    The origin of the mammalian order Eulipotyphla has been debated intensively with arguments around whether they began diversifying before or after the Cretaceous-Palaeogene (K-Pg) boundary at 66 Ma. Here, we used an in-solution nucleotide capture method and next generation DNA sequencing to determine the sequence of hundreds of ultra-conserved elements (UCEs), and conducted phylogenomic and molecular dating analyses for the four extant eulipotyphlan lineages—Erinaceidae, Solenodontidae, Soricidae, and Talpidae. Concatenated maximum-likelihood analyses with single or partitioned models and a coalescent species-tree analysis showed that divergences among the four major eulipotyphlan lineages occurred within a short period of evolutionary time, but did not resolve the interrelationships among them. Alternative suboptimal phylogenetic hypotheses received consistently the same amount of support from different UCE loci, and were not significantly different from the maximum likelihood tree topology, suggesting the prevalence of stochastic lineage sorting. Molecular dating analyses that incorporated among-lineage evolutionary rate differences supported a scenario where the four eulipotyphlan families diversified between 57.8 and 63.2 Ma. Given short branch lengths with low support values, traces of rampant genome-wide stochastic lineage sorting, and post K-Pg diversification, we concluded that the crown eulipotyphlan lineages arose through a rapid diversification after the K-Pg boundary when novel niches were created by the mass extinction of species.

    Shrew species have been proposed to utilize an echo‐based orientation system to obtain additional acoustic information while surveying their environments. This system has been supported by changes in vocal emission rates when shrews encounter different habitats of varying complexity, although detailed acoustic features in this system have not been reported. In this study, behavioral experiments were conducted using the long‐clawed shrew (Sorex unguiculatus) to assess this orientation system. Three experimental conditions were set, two of which contained obstacles. Short‐click, noisy, and different types of tonal calls in the audible‐to‐ultrasonic frequency range were recorded under all experimental conditions. The results indicated that shrews emit calls more frequently when they are facing obstacles or exploring the experimental environment. Shrews emitted clicks and several different types of tonal calls while exploring, and modified the use of different types of calls for varying behavior. Furthermore, shrews modified the dominant frequency and duration of squeak calls for different types of obstacles, that is, plants and acrylic barriers. The vocalizations emitted at short inter‐pulse intervals could not be observed when shrews approached these obstacles. These results are consistent with the echo‐based orientation hypothesis according to which shrews use a simple echo‐orientation system to obtain information from their surrounding environments, although further studies are needed to confirm this hypothesis.

    The Japanese white-toothed shrew (Crocidura dsinezumi) is a species endemic to Japan. For this species, only minimal phylogeographic investigations have been conducted. We obtained DNA sequences of mitochondrial cytochrome b and control region and nuclear ApoB genes for 191 individuals of C. dsinezumi from 107 locations collected throughout its known range. In the phylogenetic trees based on mitochondrial DNA sequences, two haplogroups (Eastern and Western Clades) were recognized, and the demarcation line between them was located in central Honshu without an overlapping area. The estimated divergence time between the two major clades indicated that they could have diverged prior to the final geologic division of Hondo and the Asian Continent (100–150 KYA). For the ApoB gene, Types A, G, and R (heterozygote) were recognized although there was a single site mutation. Type A mainly occurs in eastern and central Japan and Types G and R in central and western Japan. It was suggested in the present study that some shrews in Hokkaido were introduced recently from eastern Honshu (possibly the Tohoku Region) whereas others might have been distributed there naturally, and that population in Jeju (South Korea) was introduced recently from Kyushu.

    An individual of Laxmann’s shrew (Sorex caetutiens Laxmann, 1788) with completely white pelage was captured on 5 December, 2011 in Hamanaka-cho, Hokkaido, Japan. It was captured alive by a house cat and kept in a cage until it died on 12 May, 2012. It is the first record of S. caetutiens with a completely white pelage in Japan. Owing to its pinkish skin and iris, it seems to be albinistic rather than leucistic, although the gene causing the white pelage has not been determined yet. This specimen (skin, skull and bodies in ethanol) was tentatively deposited at the Institute of Low Temperature Science, Hokkaido University.

    The house shrew (Suncus murinus-S. montanus species complex) is considered to have been unintentionally introduced by humans from their original range to other regions around the Indian Ocean and neighboring seas, but this has yet not fully been investigated. A phylogenetic tree and haplotype network were reconstructed based on the mitochondrial cytochrome b gene nucleotide sequences (1140 bp) of 179 individuals of house shrews from 46 localities in southern East Asia, Southeast Asia, West Asia, and islands in the western Indian Ocean. There was small genetic variation among shrews in Japan (Okinawa), southern China, Vietnam, and insular Southeast Asia. However, the shrew populations in Myanmar and Sri Lanka showed of a variety of different haplotypes. In the region of the western Indian Ocean, three interesting findings were obtained. First, the shrews on Zanzibar Island (Tanzania) shared same haplotype as those in southwestern Iran, and the haplotype was close to a group in Pakistan, despite these three regions being distantly located. Second, inferring from the haplotype network, it was suggests that the shrews in Yemen might have derived from Madagascar/Comoros populations. Third, the shrews on Réunion Island were genetically different from other populations around the western Indian Ocean but closer to Malaysia and Myanmar populations. Thus, the present study demonstrates that there have been dynamic immigration/emigration processes in the house shrews, especially for those around the western Indian Ocean. In addition, the house shrews in Myanmar may include several different species.

    A phylogenetic tree was reconstructed based on the mitochondrial cytochrome b gene nucleotide sequences of 169 individuals of house shrews (Suncus murinus and S. montanus) from 44 localities in East Asia, Southeast Asia, West Asia, and islands in the western Indian Ocean. Shrews from China (Zhejiang), Japan (Okinawa), Vietnam, and Indonesia (Java) formed a monophyletic group with less genetic variation. Therefore, the shrews of these regions appeared to have originated from one or a few localities. Contrary to this, shrews from Sri Lanka, Myanmar, and Pakistan consisted of several haplogroups. This finding suggests immigration movements to these areas. Fascinating findings were also obtained concerning the islands in the western Indian Ocean. First, shrews on Zanzibar Island (Tanzania) had almost the same haplotype as those in southwestern Iran. Therefore, the house shrew in Zanzibar may have immigrated from Iran (or vice versa). Second, shrews from Madagascar and Grande Comore Island shared the same haplotype, whereas the shrews on Reunion Island were clearly different from those of Madagascar and Comoros. Thus, there appears to have been several immigration routes to the islands of the western Indian Ocean.

    Variability in the coat color of the house mouse, Mus musculus, provides an opportunity to study the evolution of phenotypes in this species. Here we associated genetic variations with coat color in seven mice from Madagascar that had identical M. m. gentilulus mitochondrial DNA sequences. The entire coding region of the 948-base pair (bp) coat-color-related gene, Mc1r, was shown to have no nonsynonymous changes. However, analyses of the two exon-1 promoter regions-termed 1A (317 bp) and 1B (499 bp)-from a second gene, Asip, which is also involved in the evolution of coat color, revealed two distinct haplotypes in each region. Associations between Asip promoter regions and dorsal color were ambiguous; however, two ventral color types-light and dark gray-were associated with the haplotypes of 1A, as determined by clustering analysis. Notably, the haplotype of the light gray animals was identical to the Asip A(w) allele that is associated with white bellies.

    In a soil ecosystem, bottom-up control is generally considered more influential than top-down control, although some empirical studies have suggested that predators have a trophic cascade effect on soil animals at lower trophic levels. In the present study, the effects of the long-clawed shrew, a mammalian predator at a high trophic level, on the soil invertebrate community and litter decomposition were investigated in a field experiment using enclosures. In the presence of the shrew, the population densities of earthworms, isopods and spiders tended to decrease, whereas that of large springtails and centipedes appeared to increase. This result might have been caused by the shrew's direct predation on the former invertebrates and the release from predation by spiders on springtails. The reason of the increase of centipedes was unknown. Shrew had no effects on litter decomposition rates both by litter trap analysis and litter-bag test. The top-down effects of shrews on litter decomposition might have been diluted through a complex food-web and the observing period of the present study might be too short to detect litter decomposition process. Experiment for longer time might demonstrate more explicit effect of the shrew on the soil ecosystem.

    The Cuban solenodon (Solenodon cubanus) is one of the most enigmatic mammals and is an extremely rare species with a distribution limited to a small part of the island of Cuba. Despite its rarity, in 2012 seven individuals of S. cubanus were captured and sampled successfully for DNA analysis, providing new insights into the evolutionary origin of this species and into the origins of the Caribbean fauna, which remain controversial. We conducted molecular phylogenetic analyses of five nuclear genes (Apob, Atp7a, Bdnf, Brca1 and Rag1; total, 4,602 bp) from 35 species of the mammalian order Eulipotyphla. Based on Bayesian relaxed molecular clock analyses, the family Solenodontidae diverged from other eulipotyphlan in the Paleocene, after the bolide impact on the Yucatan Peninsula, and S. cubanus diverged from the Hispaniolan solenodon (S. paradoxus) in the Early Pliocene. The strikingly recent divergence time estimates suggest that S. cubanus and its ancestral lineage originated via over-water dispersal rather than vicariance events, as had previously been hypothesised.

    Although based on very limited M and L segment sequences, Artybash virus (ARTV) was proposed previously as a unique hantavirus harbored by the Laxmann's shrew (Sorex caecutiens). To verify this conjecture, lung tissues from 68 Laxmann's shrews, captured during 2006 to 2014 in eastern Siberia, Russia, and Hokkaido, Japan, were analyzed for ARTV RNA using reverse transcription polymerase chain reaction (RT-PCR). ARTV RNA was detected in six Laxmann's shrews. Pairwise alignment and comparison of partial-and full-length S, M, and L segment sequences from these Laxmann's shrews, as well as phylogenetic analyses, using maximum likelihood and Bayesian methods indicated that ARTV was distinct from other soricine shrew-borne hantaviruses and representative hantaviruses harbored by rodents, moles, and bats. Taxonomic identity of the ARTV-infected Laxmann's shrews was confirmed by full-length cytochrome b mitochondrial DNA sequence analysis. Our data indicate that the hantavirus previously known as Amga virus (MGAV) represents genetic variants of ARTV. Thus, the previously proposed designation of ARTV/MGAV should be replaced by ARTV.

    The multiple skeletal components of the skull originate asynchronously and their developmental schedule varies across amniotes. Here we present the embryonic ossification sequence of 134 species, covering all major groups of mammals and their close relatives. This comprehensive data set allows reconstruction of the heterochronic and modular evolution of the skull and the condition of the last common ancestor of mammals. We show that the mode of ossification (dermal or endochondral) unites bones into integrated evolutionary modules of heterochronic changes and imposes evolutionary constraints on cranial heterochrony. However, some skull-roof bones, such as the supraoccipital, exhibit evolutionary degrees of freedom in these constraints. Ossification timing of the neurocranium was considerably accelerated during the origin of mammals. Furthermore, association between developmental timing of the supraoccipital and brain size was identified among amniotes. We argue that cranial heterochrony in mammals has occurred in concert with encephalization but within a conserved modular organization.

    Assessing local people's knowledge of endangered species is important not only for the planning and implementation of environmental education programs, but also to address community-based conservation issues and guarantee an effective engagement of local residents in conservation efforts. A questionnaire-based study conducted in Alejandro de Humboldt National Park assessed local people's knowledge of the endangered Cuban Solenodon (Solenodon cubanus). From this it was found that although children seem to be better informed than adults with respect to the Cuban Solenodon, more needs to be done to educate both age and groups alike. This study also highlighted local residents' positive disposition to actively participate in the Cuban Solenodon conservation effort.

    Invasion status and impacts of nonnative brook trout (Salvelinus fontinalis) in a Hokkaido stream were investigated with field surveys and genetic analyses. Nonnative brook trout was detected in nine (41 %) of the 22 sampled reaches in three tributaries of the Sorachi River, Hokkaido, Japan. Based on the external pigmentation, twelve putative hybrids between brook trout and native white-spotted charr (Salvelinus leucomaenis) were collected in two reaches. Microsatellite and mitochondrial DNA data established that 58% of these hybrids were first-generation (F-1) progenies between male brook trout and female white-spotted charr. Our results suggest potential negative impacts of nonnative brook trout on native charr populations in Hokkaido through interspecific interactions.

    Phylogenetic analysis was conducted for various populations of the Sorex minutissimus-S. yukonicus complex based on mitochondrial gene (cytochrome b and/or the control region) sequences. Sorex minutissimus was divided into some monophyletic groups in Eurasia; it was divided into 2 main groups, eastern and western Eurasian clades, based on combined data of the cytochrome b and the control region. Monophyly of shrews from Hokkaido-Sakhalin, Primorye, Mongolia-Transbaikalia, southeastern Finland was strongly supported respectively in most analyses. Sorex yukonicus was phylogenetically close to S. minutissimus in eastern Siberia. Some shrews from western and central Siberia were included in the clade of southeastern Finland Also, most shrews from central-northern Finland and Norway made a clade close to but different from the southeastern Finland clade. This finding suggests that Fennoscandian shrews might consist of individuals which were recolonised from various refugia after the Last Glacial Maximum. Nucleotide diversity of shrews from Hokkaido and Alaska was low. Three regional groups in Kamchatka-Sakha, Sakhalin, and Mongolia-Transbaikalia tended to have medium nucleotide diversity. In contrast, shrews from Cisbaikalia-western Siberia and Fennoscandia had high nucleotide diversity. The S. minutissimus-S. hosonoi group appears to have experienceed a quit different biogeographic history from two shrews with similar ranges, the S. caecutiens-S. hosonoi group and S. tundrensis.

    he sable is an important animal for fur trade in the world since the ancient time in Eurasia. Therefore,it is important to review the names for the sables in various languages in Eurasia to investigate the transmission of words for the sables. In the present paper, to give basic information for the transmission and transformation of the words for the sable in Eurasia, words for the sable and 3 other species of marten (Martes sp.), weasels, and squirrels in Eurasian languages were investigated. In East Asia, the sable is called in various words. The sable was called "furuki" (or fuluki) in ancient Japan (ca. 8 to 13 c.). It is called “hoinu" -like words in Ainu language,"dambi" with modifiers or other words in Korean, "bulgan"-like words in Mongolic languages,and "segep" -like words in Tungusic languages, and "diao" with modifiers in Chinese. In the regions of central-western Eurasia where the sable is (was) distributed,the sable is called in words of "bulgan"-like words in Mongolic languages, those of "kish"-like words in Turkic languages, "nukse"-like words in Finno-Ugric languages, and "sobol'" in Russian. In Iranian languages, the sable is fundamentally called in "samur". The word "samur" is spread in central-western Asia and southeastern Europe. In northern-western Europe,the sable is called in "sobol"-like words. In Eurasian languages, martens are sometimes called in the words related with squirrels. Especially,it is note worthy that squirrels are called "uluki" -like words in Tungusic languages.

    During the 8th-12th centuries in Japan, "furuki-no-kawaginu" or sable coat was the rage among high class aristocrats and was a symbol of nobility and wealth. However, the shape is almost unknown because there are no remains or no drawings. However, "furuki-no-kawaginu" was described in some literary works and diaries in ancient Japan, which contain a little information of the shape. In addition, drawings and remains of sable coats in other regions and periods in East Asia potentially have information of the shape of the ancient Japanese coat. In this report, the shape is inferred based on those sources of information. "Furuki-no-kawaginu" was divided into at least two size groups : long and short types. Further, the front part of the coat seems to divide right and left. Some other features were also inferred.

    Soil bacteria play important roles as litter decomposers in most terrestrial ecosystems and microbial activity is affected by activities of soil invertebrates. In soil ecosystems of forests in Hokkaido, the long-clawed shrew is an important predator whose preying on soil invertebrates may indirectly affect soil bacterial communities. To estimate indirect top-down effects of shrews on the soil bacterial community, field experiments were conducted using enclosures in which shrews were introduced and removed, and changes in bacterial community composition, species richness, diversity, and evenness were observed using automated ribosomal intergenic spacer analysis (ARISA). Abiotic environmental conditions (ambient temperature, soil temperature, soil moisture content and soil pH) were also considered. Bacterial community structure was significantly affected by soil moisture content and soil temperature. The significant causes of the change in bacterial species richness, diversity, and evenness varied among experimental treatments; however, soil moisture tended to have significantly negative effects on these indices in all cases. In the present study, effects of shrews on the bacterial community were not detected.

    Taxonomic status of fossil Sorer shrew specimens from the late Middle Pleistocene of Honshu Island was addressed. Multivariate analyses of upper and lower jaws were conducted for the fossil specimens as well as for 8 species of Recent Sorer shrews from Japan and adjacent regions. It was confirmed that S shinto and S hosonoi already inhabited Honshu Island in the late Middle Pleistocene. Most fossil specimens previously referred to S minutissimus and S gracillimus Honshu should be regarded as S hosonoi, although some specimens could not be completely distinguished from S gracillimus. Thus, the appearance of S hosonoi ascends, at least, to the late Middle Pleistocene during which time they were more broadly distributed, including northern Honshu, than at present (only in central Honshu) Most middle size fossils should be regarded as S shinto, but at least one specimen was identified as S caecutiens It was also demonstrated that other species of Sorex shrews larger than S shinto and S hosonoi were present during the Middle Pleistocene of Japan Most of the large fossils were considered to be S isodon, which had not been recorded from and is now absent in the Japanese Islands In addition, there was one specimen of another large species, S unguiculatus, in Honshu during the Middle Pleistocene, which now is absent in Honshu.

    Asiatic wild cat, Felis silvestris ornata, once regarded as least concern is declining rapidly in its natural habitat in the Xinjiang desert region of China mainly because of excessive hunting for pelt trade followed by shrinkage of its habitat due to cultivation, oil and gas exploration and excessive use of pesticides. Prior to 1950, it was the most abundant felid in Xingjian dwelling along all major river basin systems and Taklimakan desert but later it got confined to three regions of southern Xinjiang only viz., Bayingolin Mongol Autonomous Oblast, Aksu and Hotan. Despite several expeditions, correct distribution and status of this illusive cat was unknown. This review article is an update on current status, distribution, ecological behavior, conservationand habitat characteristics of Asiatic wild cat in Xinjiang arid region of China. Specimen collected from various parts of Xinjiang exhibit varied phenotypic characters. It has protruding morphological features like many other desert animals. It has dense and soft hairs on the forelimb pads like other felids but rarely behaves nocturnally, adjusting its movement with seasonal variation and food availability. Tarim hare, Lepus yarkandensis, is the primary source of food followed by gerbil, jerboa, birds, fish and lizards. Literature and the statistics both reveal that it's remnant population is declining fast limiting it to only a few fragmented habitats in the lower reaches of Hotan, Yarkand, Tarim, Qarqan, Niya and Keriya river basins, rendering it no more a least concern species at least in China. Therefore, adequate policy decisions and concrete conservation actions are required to halt and eventually reverse the declining population of the cat and its deteriorating habitat in Xinjiang.

    Recent molecular evidence of genetically distinct hantaviruses in shrews, captured in widely separated geographical regions, corroborates decades-old reports of hantavirus antigens in shrew tissues. Apart from challenging the conventional view that rodents are the principal reservoir hosts, the recently identified soricid-borne hantaviruses raise the possibility that other soricomorphs, notably talpids, similarly harbor hantaviruses. In analyzing RNA extracts from lung tissues of the Japanese shrew mole (Urotrichus talpoides), captured in Japan between February and April 2008, a hantavirus genome, designated Asama virus (ASAV), was detected by RT-PCR. Pairwise alignment and comparison of the S-, M-, and L-segment nucleotide and amino acid sequences indicated that ASAV was genetically more similar to hantaviruses harbored by shrews than by rodents. However, the predicted secondary structure of the ASAV nucleocapsid protein was similar to that of rodent- and shrew-borne hantaviruses, exhibiting the same coiled-coil helix at the amino terminus. Phylogenetic analyses, using the maximum-likelihood method and other algorithms, consistently placed ASAV with recently identified soricine shrew-borne hantaviruses, suggesting a possible host-switching event in the distant past. The discovery of a mole-borne hantavirus enlarges our concepts about the complex evolutionary history of hantaviruses.

    We sequenced 2167 base pairs (bp) of mitochondrial DNA cytochrome b and 16S, and 1390 bp of nuclear genes BRCA1 and ApoB in shrews taxa (Eulipotyphla, family Soricidae). The aim was to study the relationships at higher taxonomic levels within this family, and in particular the position of difficult clades such as Anourosorex and Myosorex. The data confirmed two monophyletic subfamilies, Soricinae and Crocidurinae. In the former, the tribes Anourosoricini, Blarinini, Nectogalini, Notiosoricini, and Soricini were supported. The latter was formed by the tribes Myosoricini and Crocidurini. The genus Suncus appeared to be paraphyletic and included Sylvisorex. We further suggest a biogeographical hypothesis, which shows that North America was colonized by three independent lineages of Soricinae during middle Miocene. Our hypothesis is congruent with the first fossil records for these taxa. Using molecular dating, the first exchanges between Africa and Eurasia occurred during the middle Miocene. The last one took place in the Late Miocene, with the dispersion of the genus Crocidura through the old world. (c) 2006 Elsevier Inc. All rights reserved.

    Molecular phylogeny of soricid shrews (Soricidae, Eulipotyphla, Mammalia) based on 1140 bp mitochondrial cytochrome b gene (cytb) sequences was inferred by the maximum likelihood (ML) method. All 13 genera of extant Soricinae and two genera of Crocidurinae were included in the analyses. Anourosorex was phylogenetically distant from the main groupings within Soricinae and Crocidurinae in the ML tree. Thus, it could not be determined to which subfamily Anourosorex should be assigned: Soricinae, Crocidurinae or a new subfamily. Soricinae (excluding Anourosorex) should be divided into four tribes: Neomyini, Notiosoricini, Soricini and Blarinini. However, monophyly of Blarinini was not robust in the present data set. Also, branching orders among tribes of Soricinae and those among genera of Neomyini could not be determined because of insufficient phylogenetic information of the cytb sequences. For water shrews of Neomyini (Chimarrogale, Nectogale and Neomys), monophyly of Neomys and the Chimarrogale-Nectogale group could not be verified, which implies the possibility of multiple origins for the semi-aquatic mode of living among taxa within Neomyini. Episoriculus may contain several separate genera. Blarinella was included in Blarinini not Soricini, based on the cytb sequences, but the confidence level was rather low; hence more phylogenetic information is needed to determine its phylogenetic position. Furthermore, some specific problems of taxonomy of soricid shrews were clarified, for example phylogeny of local populations of Notiosorex crawfordi, Chimarrogale himalayica and Crocidura attenuata.

    We investigated the genetic structure of Sorex unguiculatus and Sorex caecutiens populations in Hokkaido, Japan, using hypervariable microsatellite DNA markers. We used five microsatellite loci to type 475 S. unguiculatus individuals from 20 localities on the Hokkaido mainland and four localities from each of four offshore islands (and 11 shrews from one locality in southern Sakhalin for a particular analysis). We used six microsatellite loci to type 240 S. caecutiens individuals from 13 localities on the Hokkaido mainland. Genetic variation was high in mainland populations of both species and low in the island populations of S. unguiculatus. Allelic richness and island size were positively correlated for S. unguiculatus, suggesting that genetic drift occurred on those islands due to small population size. In addition, four insular populations of S. unguiculatus were genetically differentiated from the mainland populations, although clear phylogeographic clustering was not confirmed among populations on the Hokkaido mainland for either S. unguiculatus or S. caecutiens. Heterozygosity excess was observed in more than half of the populations including the mainland populations of the two species, suggesting recent bottleneck events in these populations. Population dynamics of the shrews might be explained by a metapopulation scheme. According to autocorrelation analysis, the extent of non-random spatial genetic structure was approximately 100 km. Isolation by distance was observed in S. unguiculatus, but not in S. caecutiens although there is a positive trend. The lack of correlation for S. caecutiens might have been due to small sample size. Thus, no obvious differences in population genetic structure were found between the two species on the Hokkaido mainland in the present study, while previous investigations using mitochondrial DNA sequences inferred that these two species might have rather different biogeographic histories.

    We estimated phylogenetic relationships among shrews of the <i>Sorex caecutiens/shinto</i> group (Eulipotyphla, Soricidae) from various locations through its range, based on restriction fragment length polymorphism (RFLP) analysis of the nuclear ribosomal RNA gene (rDNA) spacer region. Seven rDNA-RFLP repetitive types (repetypes) were recognized among 15 shrews examined. Restriction patterns of <i>Sorex caecutiens</i> Laxmann, 1788 and <i>S. shinto</i> Thomas, 1905 were distinguishable from each other, but the separation was not statistically supported in the maximum parsimony analysis. The RFLP repetype from Cheju Island was close to that of <i>S. caecutiens</i> from the Eurasian continent, indicating that the shrew of Cheju should be classified as<i> S. caecutiens</i>. Within <i>S. caecutiens</i>, there were two alternative phylogenetic hypotheses. According to a parsimonious tree and a simple network, the Hokkaido population was regarded to be derived from the Sakhalin population, which in turn was derived from the continental population. Alternatively, it was inferred that the continent and Hokkaido populations were firstly separated from the ancestral population, and then shrews from both populations immigrated into Sakhalin and hybridization occurred there. The latter hypothesis seems to be more plausible because it is more congruent with a previous mitochondrial phylogeny.<br>

    A new tissue kallikrein-like protease, blarinasin, has been purified from the salivary glands of the short-tailed shrew Blarina brevicauda. Blarinasin is a 32-kDa N-glycosylated protease with isoelectric values ranging between 5.3 and 5.7, and an optimum pH of 8.5 for enzyme activity. The cloned blarinasin cDNA coded for a pre-pro-sequence and a mature peptide of 252 amino acids with a catalytic triad typical for serine proteases and 43.7-54.0% identity to other mammalian tissue kallikreins. Blarinasin preferentially hydrolysed Pro-Phe-Arg-4-methylcoumaryl-7amide (MCA) and N-tert-butyloxycarbonyl-Val-Leu-Lys-MCA, and preferentially converted human high-molecular-weight kininogen (HK) to bradykinin. The activity of blarinasin was prominently inhibited by aprotinin (K-i=3.4 nm). A similar kallikrein-like protease, the lethal venom blarina toxin, has previously been purified from the salivary glands of the shrew Blarina and shows 67.9% identity to blarinasin. However, blarinasin was not toxic in mice. Blarinasin is a very abundant kallikrein-like protease and represents 70-75% of kallikrein-like enzymes in the salivary gland of B. brevicauda.

    Karyotypes of Sorex caecutiens from Cheju Island of Korea were examined with conventional staining and G-banding by trypsin treatment stained with Giemsa (GTG). The diploid and fundamental autosomal arm numbers were 42 and 66, respectively. The autosomal complement in the karyotype comprised six pairs of metacentrics, seven pairs of submetacentrics or subtelocentrics, and seven pairs of acrocentrics. The X was a largest acrocentric chromosome, and the Y was a small subtelocentric chromosome. Chromosomal constitutions and G-banding partern of S. caecutiens from Cheju Island were essentially identical to those reported for S. shinto from Honshu Island, Japan. This similarity may indicate the ancestral character of the monophyletic S. caecutiens/shinto group.

    We investigated the morphological relationships among eight populations of Sorex caecutiens/ shinto group in East Asia using 11 cranial and dental characters and four external characters. Univariate and multivariate analyses of these characters failed to distinguish S. caecutiens and S. shinto. Morphological characters were, in fact, continuous between populations. Sorex shinto from Honshu was similar to S. caecutiens from the Korean peninsula and Primorye in skull dimensions and to S. caecutiens from Hokkaido-Sakhatin in external dimensions. Sorex caecutiens from Cheju Island is morphologically similar to S. shinto from Sado and Shikoku islands. These three insular populations were characterized by having large body sizes. Sorex caecutiens from Cheju was the Largest of the S. caecutiensl/hinto group in East Asia. This shrew from Cheju was classified definitively as S. caecutiens on DNA data, but has a unique morphology among S. caecutiens populations in East Asia. We therefore regard this Sorex shrew on Cheju Island as a new subspecies of S. caecutiens and designate it S. c. hallamontanus Abe and Oh. (c) 2005 Deutsche Gesellschaft fur Sugetierkunde.

    Phylogenetic relationships among 8 species of white-toothed shrews (Crocidurinae, Mammalia) in East and Central Asia were evaluated based on mitochondrial cytochrome-b gene sequences. The taxon formerly regarded as Crocidura suaveolens in East Asia phylogenetically is distinct from that of true C. suaveolens in Europe, suggesting that specimens in East Asia should be considered a distinct species, C. shantungensis. All shrews from Central Asia were regarded as C. sibirica, although phylogenetic comparison with the unsampled C. gmelini is needed to confirm its taxonomic status. C. shantungensis, C. suaveolens, and C. sibirica formed a well-supported monophyletic group. C. dsinezumi, C. lasiura, C. kurodai, and C. watasei also formed a well-supported monophyletic group. Within C. dsinezumi, there were 2 clusters, referable to western and eastern Japan. Based on low genetic divergence, C. dsinezumi on Cheju and Hokkaido islands appear to be the result of a recent introduction from western Japan and northern-eastern Honshu, respectively.

    Venomous mammals are rare, and their venoms have not been characterized. We have purified and characterized the blarina toxin (BLTX), a lethal mammalian venom with a tissue kallikrein-like activity from the submaxillary and sublingual glands of the shorttailed shrew Blarina brevicauda. Mice administered BLTX i.p. developed irregular respiration, paralysis, and convulsions before dying. Based on the amino acid sequence of purified protein, we cloned the BLTX cDNA. It consists of a prosequence and an active form of 253 aa with a typical catalytic triad of serine proteases, with a high identity with tissue kallikreins. BLTX is an N-linked microheterogeneous glycoprotein with a unique insertion of 10 residues, L(106)TFFYKTFLG(115). BLTX converted kininogens to kinins, which may be one of the toxic pathogens, and had dilatory effects on the blood vessel walls. The acute toxicity and proteolytic activity of BLTX were strongly inhibited by aprotinin, a kallikrein inhibitor, suggesting that its toxicity is due to a kallikrein-like activity of the venom.

    Chromosomes of the short-tailed shrew Blarina brevicauda, which display the numerical polymorphism arisen from Robertsonian rearrangements, were analyzed with conventional and silver staining and G- and C-banding techniques. With respect to all specimens examined in the present study, the diploid chromosome number (2n) and fundamental autosomal arm number (FN) were 50 and 48, respectively. The karyotype consisted of 24 pairs of acrocentric autosomes, a large-sized metacentric X chromosome, and a small-sized submetacentric Y chromosome. The comparison with previous findings suggested the geographic polymorphism of Y chromosome in this species. All autosomes and the X chromosome carried slight centromeric constitutive heterochromatin, whereas the Y chromosome was entirely heterochromatic. On the satellites of short arms of two autosomal pairs, the nucleolus organizer regions (NORs) were recognized. The G- and C-banded and Ag-NOR-stained karyotypes presented in the present study could be useful cytogenetic characteristics for specification of chromosomes participating in Robertsonian rearrangements within this species and for karyo-systematic study of genus Blarina.

    Phylogenetical positions of Sorex specimens unassigned to species from Cheju Island, Korea, and S. caecutiens from southern Korean Peninsula were investigated based on full nucleoticle sequences (1, 140 bp) of the mitochondrial cytochrome b gene, comparing specimens of the S. caecutiens/shinto group from locations throughout its range. In the phylogenetic tree obtained, S. caecutiens were separated into two main groups: Hokkaido and Continent-Sakhalin-Cheju clusters. Shrews from Cheju and Korean Peninsula were included in the latter cluster. Thus, we suggest that the shrew on Cheju Island should be ranked as S. caecutiens, although taxonomic description of the shrew has to be conducted elsewhere. The Cheju shrews formed a single sub-cluster while the peninsular shrews were not included in a single sub-cluster. The clustering of individuals in Continent-Sakhalin-Cheju cluster did not always reflect the geographical proximity of their capture locations. We interpret these findings as indicating ancestral isolation of a Hokkaido population and recent rapid range expansion of the modern population in Eurasian Continent-Sakhalin-Cheju.

    We isolated six microsatellite markers from the partial genomic libraries of two Sorex shrews, S. unguiculatus and S. caecutiens, and examined their allelic variation. All loci showed high allelic variation ranging from 15 to 19 alleles and all but one locus conformed to Hardy-Weinberg expectations in the species where the loci were isolated. Cross-species amplifications showed that all primers derived from S. unguiculatus were useful for S. caecutiens, while among primer sets derived from S. caecutiens only one was useful for S. unguiculatus. Accordingly, at least five microsatellite markers were useful in S. caecutiens and three in S. unguiculatus.

    Molecular phylogeny of crocidurine shrews (Insectivora, Soricidae) in northeastern Asia was investigated to confirm the taxonomic status of unidentified specimens of Crocidura from Cheju Island, South Korea. Phylogenetic trees were constructed by neighbor-joining (NJ) and maximum likelihood (ML) methods, based on mitochondrial cytochrome b gene sequences (402 base pairs) of 37 individuals of seven crocidurine species and three unidentified specimens from 31 localities mainly in northeastern Asia. Phylogenetic position of the three unidentified specimens from Cheju Island were compared with those of Suncus marinus, C. attenuata, C. dsinezumi, C. lasiura, C. sibirica, C. suaveolens, and C. walasei. Both in NJ and ML trees, the three unidentified specimens were included in the cluster of C. dsinezumi and were obviously different from C. suaveolens on Cheju Island, Thus, the present investigation demonstrated that both C. suaveolens and C. dsinezumi exist on Cheju Island.

    In order to develop a new accurate method for sexing in Sorex species (Soricidae, Insectivora), we synthesized a polymerase chain reaction (PCR) primer set to amplify a part of Sry HMG box in the long-clawed shrew, Sorex unguiculatus. When the primers were applied to the samples of known sex, PCR products were successfully obtained for males as a clear, single band on 3% agarose gels after electrophoresis in Sorex unguiculatus and five other Sorex species, but not for females of these six species. Thus, PCR amplification using the primer set may be applicable to discern sex in the six Sorex species.

    Intraspecific phylogeny and genetic variation were investigated based on nucleotide sequences of the mitochondrial cytochrome b gene in six soricine shrew species, Sorex unguiculatus, S. caecutiens, S. shinto, S. gracillimus, S. minutissimus and S. hosonoi, collected primarily from northeastern Asia. Maximum likelihood trees and a phylogenetic network were generated to estimate intraspecific phylogenies. S. minutissimus showed high congruence between phylogenetic position and geographical origin and S. gracillimus showed low congruence. In contrast, there was no congruence between phylogeny and geography in S. unguiculatus and the S. caecutiens from Sakhalin-Eurasia. Positive correlation between genetic and geographical distances was found in S. minutissimus and S. gracillimus, but not in the other species (or regional populations). The results of the phylogenetic and genetic analyses suggest that S. minutissimus and S. gracillimus have occupied their present ranges for a longer time than the other species if we assume a stepping-stone model of population structure. In addition, there was no contradiction between the present investigations and the hypotheses of multiple immigration by S. gracillimus and a single immigration by S. unguiculatus into Hokkaido Island. It is proposed that these six northeastern Asian species experienced different historical processes of range expansion and dispersal despite the fact that some of them currently show similar patterns of distribution.

    We revised the taxonomic status of a white-toothed shrew (Insectivora, Mammalia) on Cheju Island, South Korea, which has been regarded as Japanese white-toothed shrew, Crocidura dsinezumi, by analyzing karyotype and restriction fragment length polymorphism (RFLP) for the nuclear ribosomal RNA gene (rDNA) spacer regions. Karyotype of a specimen of Crocidura from Cheju Island was the same as in lesser white-toothed shrew, C. suaveolens, from Tsushima Island and the Eurasian Continent, carrying 2n = 40 and FN (fundamental arm number of diploid autosomal set) = 46, whereas C. dsinezumi from the Japanese Islands shows 2n = 40 and FN = 52. The rDNA-RFLP was examined in two specimens of Crocidura from Cheju Island, two C. dsinezumi from Japan (Honshu and Kyushu), and one C. suaveolens from the Korean Peninsula, using six restriction sites with the 28S mouse rDNA probe. The shrews from Cheju Island possessed four restriction sites common to C. suaveolens from the Korean Peninsula but only one site common to C. dsinezumi, indicating the shrews from Cheju Island are genetically more close but distinct from the Korean Peninsula populations of C. suaveolens. From the results of karyotype and rDNA-RFLP, the specimens from Cheju Island can be regarded as C. suaveolens as a taxonomic unit.

    To establish phylogenetic relationships within the corvine birds at the interspecific and intergeneric levels, the sequence of the mitochondrial DNA cytochrome b gene was analyzed. The NJ, UPGMA, and MP trees showed similar clustering. Relationships between the jungle crow, on the one hand, and the rook and Australian raven, on the other hand, were closer than those between the jungle crow and the hooded and carrion crows. The mitochondrial genome of the Australian raven displayed the closest similarity to the ancestral genome of the genus Corvus. Populations inhabiting the eastern part of the carrion crow C. corone orientations area were statistically significantly subdivided into three lineages. These data also confirmed the hypothesis on the location of the carrion crow's ancestral lineage in the southeastern part of the area. In general, the transition and transversion substitution levels, their relationships, and distribution over codon positions were similar to that already reported for birds. Synonymous transitions in the third codon position were the prevailing substitution type. Using standard calibration scales, the time of divergence between species and genera within the corvine family was estimated to be 3.1-4 and 3.8-8.8 Ma, respectively. The divergence time between the examined corvine birds and birds of paradise was from 8 to 10 Ma.

    The morphometric relationships among five operational taxonomic units of the <i>Sorex caecutiens</i>/<i>shinto</i> group (Soricidae) (<i>S. caecutiens</i> of Hokkaido, <i>S. shinto shinto</i> of Honshu including the <i>S. chouei</i> holotype, <i>S. s. shikokensis</i> of Shikoku, and <i>S. s. sadonis</i> of Sado) in the Japanese Islands, were examined using uni- and multivariate analyses of 15 cranial, dental, and external characters. The morphological analyses showed that the shrew from Hokkaido (<i>S. caecutiens</i>) and those from Honshu, Shikoku, and Sado (<i>S. shinto</i>) were exclusively differentiated. In particular, the surface structure of the fourth upper premolar completely separated the two taxa. In contrast, <i>S. s. sadonis</i> from Sado could not be completely distinguished from related taxa from Honshu and Shikoku. Thus these morphometric analyses re-confirm that <i>S. caecutiens</i> of Hokkaido, and <i>S. shinto</i> from Honshu, Shikoku, and Sado, should be treated as two separate species, as has previously been proposed on the basis of a molecular phylogenetical study.

    A hypothetical biogeographical history of northeastern Asiatic soricine shrews in the late Quaternary was developed by integrating their present distributions, fossil records, a hypothetical phylogeny, and geological investigations. First, a biological area cladogram of the northeastern Asiatic region was constructed by applying the vicariance hypothesis to the phylogeny of the caecutiens/shinto group, a monophyletic group proposed by Ohdachi et al. (1997). Comparing the biological area cladogram with a geological hypothesis by Ohshima(1990, 1991, 1992), we hypothesized a geographical history of northeastern Asia. Species were then located on the dendrogram of the geographical history, referring to the present distributions, fossil records, and phylogeny of shrews. According to our hypothesis, higher species diversity of the northern region of northeastern Asia (Hokkaido, Sakhalin, and Eastern Siberia) was achieved by several series of colonizations and habitat expansion. On the other hand, the shrew communities of the southern region (Honshu, Sado, Shikoku, and Kyushu) were created by extinction and isolation followed by speciation.

    Aggression and the use of vertical and horizontal space in the presence of con- or hetero-specific individuals were investigated in laboratory for <i>Sorex unguiculatus</i>, <i>S. caecutiens</i>, and <i>S. gracillimus</i> in Hokkaido, Japan. <i>S. unguiculatus</i> frequently used the below floor strata of experimental cages or subterranean burrows as their main area of activity, whereas <i>S. caecutiens</i> and <i>S. gracillimus</i> mainly used the cage floor or the ground surface. The presence of con- or hetero-specific individuals led to no changes in any of the three species in the use of space, or in behavioral patterns (active/inactive ; underground/resting/ moving on the ground surface). When two individual shrews were introduced into two interconnected cages, they tended to remain in separate cages, with the exception of <i>S. gracillimus</i> with a conspecific. Dominance rank was highest in <i>S. unguiculatus</i>, intermediate in <i>S. caecutiens</i>, and lowest in <i>S. gracillimus</i>. <i>S. caecutiens</i> attacked <i>S. gracillimus</i> most frequently and <i>S. gracillimus</i> received attacks from <i>S. caecutiens</i> most frequently. The implication of this research is that severe interference competition may occur in the field between <i>S. caecutiens</i> and <i>S. gracillimus</i>.

    Phylogenetic relationships among 31 operational taxonomic units of shrews (Soricidae, Mammalia), mainly from eastern Eurasia, were inferred from partial nucleotide sequences of the mitochondrial cytochrome b gene by maximum likelihood !ML! and neighbor joining (NJ) methods, Eleven monophyletic groups were recognized among the soricine shrews examined in the ML tree. However, branching orders of the groups were obscure judging from the local bootstrap values, and two out of the 11 groups were not monophyletic in the NJ tree. The phylogenetic relationships among Sorer caecutiens, S. shinto, and S. sadonis in the Japanese and Sakhalin islands, whose taxonomy was controversial, were clarified. S. shinto in the Honshu and Shikoku Islands is genetically differentiated enough to be considered a separate species from S. caecutiens, while S. sadonis could be treated as a subspecies of S. shinto. Some other taxonomic problems are also discussed.

    Synopsis. Distribution of shrews (Soricinae: Soricidae: Insectivora) and their mitochondrial gene types were investigated in the Shiretoko Peninsula. Shrews were collcted at low, medium, and high locations of both slope sides of the central mountains, Utoro and Rausu sides. Sorex unguiculatus, S. gracillimus, and S. caecutiens were captured, but the number of captured S. caecutiens was small. Sorex unguiculatus tended to be numerically dominant on Rausu side, and so did S. gracillumus on Utoro side. Densities of both of S. unguiculatus and S. gracillimus were higher on Rausu side than on Utoro side, while those did not variate among three different altitudes. 402-base regions of the mitochondrial cytochrome b gene were sequenced in 30 S. unguiculatus, and 14 gene types (haplotypes) were recognized. No clear difference in the distribution of the types was observed between altitudes nor slope sides, although it was implied that distributions of some gene types might deviate between the two sides.遠音別岳原生自然環境保全地域調査報告書 : Long term ecological studies in the Onnebetsudake wilderness area and its surrounding areas, 環境庁自然保護局[編], pp.203-210

    We conducted a survey of small terrestrial mammals by collecting samples from nine locations in southern Sakhalin, during the summer months of 1994 and 1995. Target animals included both murid and soricid species. "Panchu" kill traps and pitfall traps were used to capture animals. Most murid species captured were <i>Apodemus peninsulae</i>, <i>Clethrionomys rutilus</i>, and <i>C. rufocanus</i>. In addition, an individual of <i>Myopus schisticolor</i> was collected. Soricid species captured include <i>Sorex gracillimus</i>, <i>S. unguiculatus</i>, <i>S. caecutiens</i>, and <i>S. daphaenodon</i>.

    The diets and abundances of three sympatric shrew species (<i>Sorex unguiculatus</i>, <i>S. gracillimus</i>, and <i>S. caecutiens</i>), food resource conditions, and environmental characteristics were investigated in three habitat types (riparian forest, wind-shelter belt, and spruce forest), during seasons without snow-cover in northern Hokkaido, Japan. <i>S. unguiculatus</i> outnumbered <i>S. gracillimus</i> in both the riparian forest and wind-shelter belt, and <i>vice versa</i> in the spruce forest. <i>S. caecutiens</i> was rare in the study area. Abundances of <i>S. unguiculatus</i> and <i>S. gracillimus</i> seemed to be unrelated to those of their principal foods. The main prey of <i>S. unguiculatus</i> was earthworms, whereas <i>S. gracillimus</i> and <i>S. caecutiens</i> mainly consumed small terrestrial arthropods. <i>S. unguiculatus</i> tended to consume more earthworms in the spruce forest than in the other habitat types. The earthworm consumption appeared to directly reflect their availability per capita. Food consumption by <i>S. gracillimus</i> tended to be constant regardless of the habitat type.<br>

    Growth, metamorphosis, and gape-limited cannibalism and predation on tadpoles (Rana pirica) in larvae of salamanders (Hynobius retardatus) were investigated in laboratory. Larval period and the size at metamorphosis were correlated positively to one another in the salamanders. When embryos were exposed to low temperature, larval period were prolonged and the size at metamorphosis increased in the salamanders while larval period were extended and the size at metamorphosis decreased in the frogs. Salamander larvae reared in group had shorter larval period and smaller size at metamorphosis than those reared individually. Small salamander larvae were more vulnerable to cannibalism and mutilation than large ones. Tadpoles incurred high probability of predation and mutilation by salamander larvae even when the head widths of tadpoles attained the maximum sizes.

    Daily activity rhythms of three sympatric soricine shrews in Hokkaido were investigated. Nineteen <i>Sorex unguiculatus</i>, 13 <i>S. caecutiens</i>, and 11 <i>S. gracillimus</i> were captured, and their total activities were studied using an infrared sensor system under two different laboratory regimes (16L8D, 20&deg;C and 10L14D, 5-15&deg;C). All the three shrew species were more active during periods of darkness than during light periods; however, during the light periods most of <i>S. gracillimus</i> and some of <i>S. unguiculatus</i> and <i>S. caecutiens</i> exhibited short intermittent activity. Activity during periods of darkness was polymodal for all the three species under the 10L14D, 5-15&deg;C regime, but was bimodal in <i>S. unguiculatus</i> under the 16L8D, 20&deg;C regime. The actogram pattern of <i>S. caecutiens</i> proved to be intermediate between <i>S. unguiculatus</i> and <i>S. gracillimus</i>. Interspecific differences in activity pattern seem to be related to body size in the genus Sorex.<br>

    I investigated the number of embryos, corpora lutea, and placental scars in Sorex unguiculatus from Hokkaido, Japan, and reported supplemental data on reproduction in S. caecutiens and S. gracillimus. Counts of corpora lutea and placental scars were not efficient indicators for reproductive history because some of them disappeared immediately after ovulation or parturition in S. unguiculatus.

    Home ranges of sympatric shrews, Sorex unguiculatus Dobson, 1890 S. gracillimus Thomas, 1907 and S. caecutiens Thomas, 1907 were studied by a mark-recepture method during the non-snow covered seasons in northern Hokkaido, 1988 and 1989. Home range size of S. unguiculatus, the largest species (15.1 g for adult males), was not significantly different from that of S. gracillimus, the smallest species (4.4 g for adult males). Both S. unguiculatus and S. gracillimus had more exclusive home ranges within species than between species. Tolerance of home range overlap may be related to the reduction of dietary overlap. No reliable information of home range for S. caecutiens was obtained in this study.

    The growth, sexual dimorphism, and geographical variation in skulls of 596 brown bears (<i>Ursus arctos</i>) hunted in Hokkaido, Japan from 1971 to 1986 were investigated. Most cranial traits continued to increase after the age of sexual maturity, and in particular skulls became progressively wider with age. Skulls of males, even those of cubs and yearlings, were larger than those of females, and the difference became significant after two years of age. Skull dimensions tended to increase from south to north, in Hokkaido, and bears from the north-eastern region possessed higher brain cases and longer mandibles relative to skull length and width, than those in the southern region.<br>

    Geographic distribution and relative abundance of four species of Sorex in Hokkaido were investigated. S. unguiculatus Dobson, 1890, S. caecutiens Thomas, 1907, and S. gracillimus Thomas, 1907 are distributed throughout the mainland of Hokkaido, and S. minutissimus Thomas, 1906 appears to be distributed only in the northern and eastern regions. S. unguiculatus was recorded on 5 out of 10 investigated islands near the mainland, S. caecutiens was recorded on one island, S. gracillimus was recorded on three islands, and S. minutissimus was recorded on one island. S. unguiculatus was the dominant species in a majority of habitats (22 out of 32) and was the second most dominant in the others. S. caecutiens was the second or third most dominant species in a majority of habitats (26 out of 32) and was the dominant in the others. S. gracillimus was a less dominant species in a majority of habitats (19 out of 23) but was the dominant in the moors and highlands in the northern regions. S. minutissimus was the rarest species in Hokkaido.

    Food habits of the brown bear (Ursus aretos yesoeruis) were studied from 1975 to 1984 in 4 diverse areas on Hokkaido Island. Foods of bears varied seasonally in each area and differed among areas largely because of differences in foods available. Bears ate mainly succulent herbs in spring and summer and fruits in the fall in northern Hokkaido. Hog's-fennel (Peucedanum multivittatum) dominated the bears' diet in August and September in the alpine areas or the Daisetsu Mountains. Foods of bears on the Shiretoko Peninsula included those from the sea, but were otherwise similar to northern Hokkaido. The diet of bears on the Oshimo Peninsula was dominated by beech (Fagus crenata) buds in the spring in terms of frequency of occurrence, and actinidia (Actinidia arguta) fruit in the fall.

    Stomach contents of Mogera wogura wogura were studied based on 125 specimens trapped at the Hanno Golf Course, Hanno City, Saitama Prefecture. The contents were sorted into the following food items: animal matters, vegetable matters and others. Number of stomachs containing each food item was given for four seasonal periods, spring (March to May), summer (June to August) , autumn (September to November) and winter (December to February) . The results obtained were as follows: Insects and earthworms were the main foods of the moles. The ocourrence rate of Formicidae (adult) was the highest and Scarabaeidae (larvae) was the second. The number of stomachs containing the larvae of Scarabaeidae was found in winter and spring in plenty, but that of the adults was seen in summer and autumn, and that of the hairs of M.w. wogura as a mass was often found in winter and spring. Namely, because these seasons were breeding seasons of the moles they seemed to fight with each other. And hairs found thin in each stomachs in summer and autumn seemed to be swallowed in case of grooming. All vegetable matters were found as fibers in the stomachs in summer. Sand and soil were found in most of the stomachs. They seemed to be swallowed with other foods, moreover they might have come out of the intestines of earthworms.埼玉県飯能市の飯能ゴルフ場において採集した125個体のアズマモグラの胃内容物を調査した。1. アズマモグラの主要食物は昆虫類と貧毛類であった。2. 昆虫類のうち出現頻度は、アリ科の成虫が最も大きく、次にコガネムシ科の幼虫であった。3. コガネムシ科の幼虫を含む胃は冬と春に、また成虫を含む胃は夏と秋によく認められた。4. 貧毛類を含む胃は冬と春によく認められたが、夏と秋にはあまり認められなかった。5. アズマモグラの毛を含む胃は、とくに冬と春によく認められ、しかもかたまりとして存在していた。この時期は本種の繁殖期にあたるため、モグラどおしの闘争があったと考えられた。そして夏と秋には、わずかの毛が少数の胃内に認められたのみで、グルーミング等によって呑みこまれたものと考えられた。6. 植物質は、胃内にあっては全て繊維状を呈しており、これを含む胃は夏期に多くみられた。7. 大部分の胃内には土砂が認められたが、これは他の食物とともに不意に呑みこまれたと思われるが、土砂の一部はミミズの消化管内のものも含まれていると考えられた。

    Several kinds of shrews produce anesthetic substances which they inject into the bodies of their prey, such as earthworms and insects. The paralyzed prey are then stored in their nest. Due to the interesting ecology of shrews, we sought to isolate these anesthetic substances. We studied the American short-tailed shrew Blarina brevicauda, which produces a potent venom. Despite its classification as an "Insectivore", it consumes not only insects and other invertebrates, but also vertebrates, including prey even larger than itself. Guided by acute toxicity against mice, the extract of its submaxillary gland was separated using column chromatography, and a lethal venom, blarina toxin, and its derivative, blarinasin, were isolated. Mice injected with blarina toxin showed characteristic symptoms, i.e., irregular and quickened respiration, paralysis of the hind limbs, and convulsions before death. The mature form of the primary amino acid sequences of blarina toxin (253 residues) and blarinasin (252 residues) were determined using partial amino acid sequence analysis and cDNA cloning, respectively. Both of these proteins were a type of secretory serine protease. Studies on posttranslational modification and the mode of action of blarina toxin are in progress. We also studied the long-clawed shrew Sorex unguiculatus, which inhabits Hokkaido. Guided by the N-type calcium channel activity, the aqueous extract of its submaxillary gland was subjected to separation using ultrafiltration and column chromatography. Further purification of the active fraction using reversed-phased HPLC is in progress.
