    Scientific journal, Abstract

    The horse (Equus caballus) varieties from Skyros and Rhodes islands (Greece) in the Aegean archipelago are extremely small, reaching shoulder heights of only about 1 m. Furthermore, the Japanese archipelago is home to eight small, native horse breeds. We investigated the evolutionary morphology and provided a review of historical documentations of these horses of cultural interest in Greece and Japan, thus providing a comparison of the independent evolution of small size in islands. We integrate cranial data from historical literature with data from newly gathered and curated skulls and analyse a measurement dataset featuring various domestic and mainland horse breeds and varieties. We use non-invasive imaging to study and measure 3D models of the bony labyrinth, housing the inner ear, and the braincase endocast. When considering the effects of allometry by regressing each PC1 scores (for each set of measurements) with the cranial geometric mean from linear measurements as a body size proxy, we show that size explains a large amount of the shape variation in horse crania, the bony labyrinths and brain endocasts. We found high intrabreed variation in all the analysed datasets. Globally, there are at least 30 distinct horse populations on islands, offering the chance to further study processes of convergence in morphological divergence and evaluate the effect of drift and the environment.

    Genes & Genetic Systems, 97, 4, 193, 207, Cold Spring Harbor Laboratory, 10 Sep. 2022, [Peer-reviewed]
    English, Scientific journal, In Madagascar, the house mouse (Mus musculus) is thought to have colonized with human activities and is now one of the most abundant rodents on the island. In this study, we determined the whole-genome sequences of five Madagascar house mice captured from the wild. We examined the evolutionary history of the population by analyzing the mitochondrial and autosomal genomes. We confirmed that the mitochondrial genome lineages of Madagascar house mice formed a monophyletic clade placed at one of the most basal positions in the species. An analysis of autosomal genomic sequences indicates that the Madagascar house mice are genetically members of M. m. castaneus (CAS), but also contain genetic elements of M. m. domesticus (DOM) resulting from hybridization between subspecies. The signature of a strong population bottleneck 1000-3000 years ago was observed in both mitochondrial and autosomal genomic data. All samples showed strong genetic affinity to many CAS samples across a wide range of Indian Ocean coastal and island regions, with divergence time estimated around 4000 years ago. These findings support that the Madagascar house mice started to colonize the island with human agricultural activity, and experienced complex history for the establishment.

  • Post K-Pg diversification of the mammalian order Eulipotyphla as suggested by phylogenomic analyses of ultra-conserved elements

    English, Scientific journal, 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.
  • Acoustic emissions of Sorex unguiculatus (Mammalia: Soricidae): Assessing the echo‐based orientation hypothesis

    Ecology and Evolution, 9, 2629, 2639, Feb. 2019, [Peer-reviewed]
    English, Scientific journal, 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.

    Mammal Study, 43, 4, 245, 259, Dec. 2018, [Peer-reviewed]
    English, Scientific journal, 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.

    Honyurui Kagaku (Mammalian Science), 58, 1, 63, 65, Jun. 2018, [Peer-reviewed]
    Japanese, Scientific journal, 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.

    English, 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.

    English, 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.

    北海道立北方民族博物館研究紀要, 21, 21, 65, 94, 北海道立北方民族博物館, Mar. 2012, [Peer-reviewed]
    Japanese, 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.
  • Estimation for the shape of sable coat or jacket in ancient Japan

    Biostory, 14, 70, 81, 生き物文化誌学会, Dec. 2010, [Peer-reviewed]
    Japanese, 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.

    Pakistan Journal of Wildlife, 1, 2, 57, 63, Pakistan Wildlife Foundation, 2010, [Peer-reviewed]
    English, 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.

The feature and arrangement of pads suit with the specie specific patterns of locomotion in each species. Mole (Mogera wogura) possesses the medial tarsal process as same as those in sibling mole (Mogera imaizumii). The others (Urotrichus, Suncs and Sorex) have metatarsal pad.

    English, 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>

    Japanese, 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.

    English, Scientific journal, 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.

    English, 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>.

    Japanese, 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

    English, 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>.
  • Diets and Abundances of Three Sympatric Shrew Species in Northern Hokkaido
    OHDACHI Satoshi
    Journal of the Mammalogical Society of Japan, 20, 1, 69, 83, 一般社団法人 日本哺乳類学会, Jun. 1995, [Peer-reviewed]
    English, 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>

  • Total Activity Rhythms of Three Soricine Species in Hokkaido
    Ohdachi Satoshi
    Journal of the Mammalogical Society of Japan, 19, 2, 89, 99, 一般社団法人 日本哺乳類学会, Dec. 1994, [Peer-reviewed]
    English, 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>

    Journal of the Mammalogical Society of Japan, 17, 1, 27, 47, 一般社団法人 日本哺乳類学会, Jun. 1992, [Peer-reviewed]
    English, 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>

    Ohdachi Satoshi; Aoi Toshiki
    International Conference of Bears Research and Management, 7, 215, 220, International Association for Bear Research & Management, 1987
    English, International conference proceedings, 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.

    Bulletin of Kawagoe Senior High School, 19, 24, 29, 埼玉県立川越高等学校, 1982
    English, 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., [Domestic Conference]

    内容
    昨年度(令和3年)は、令和2年度に続いて新型コロナ対策のために北方領土に渡航することができなかった。そのかわりに研究計画にも述べてあるように北方領土に隣接した北海道東部の根室市や浜中町に哺乳動物相の捕獲調査を行った。それによると令和3年度は真無盲腸目のトガリネズミ類の個体数密度が低く、特にオオアシトガリネズミの密度がかなり減っていた。一方で浜中町ではイタチ科のラッコが海で繁殖しているのを確認した。ニホンジカについては道東地域では例年通りの高密度であった。一方、現地に直接おもむけない北方領土についての情報は国後島のクリリスク自然保護区の所長や所員から得た。それによると2021年の春の段階ではエゾシカが国後島に数頭存在しているのが確認されたが、色丹島や歯舞諸島などの他の北方領土では確認されていない。また国後島でも繁殖は確認されていない。国後島のヨーロッパミンクについては情報不足ではあるが生息していることは確かであった。事前に採集してある国後島と択捉島の環境DNAの分析では、哺乳類についてはエゾシカとヨーロッパミンクは検出されなかった。一方、淡水魚類については淡水性のサケ・マス類などが検出された。
    意義
    北方領土に隣接する北海道東部では例年通りにシカの密度は高かった。このことはいつでも北方領土へのさらなるシカの移住が起こりうることを示している。また国後島ではシカは前年に確認した個体が生存していると思われるが、繁殖していないということは、まだ当地でシカが増加するという段階にはないことを示している。一方、ヨーロッパミンクは現地調査ができない状況が最大の研究上の障害であることが明確になった。
    重要性
    モニタリングは継続することが重要であるが、現地に赴けない状況下では現地の協力機関や協力者との密な情報のやり取りにより必要な知見をえることができる。

  • Chemical Evolutionary Ecology Studies on the Repellent Substances from Shrews
    Grants-in-Aid for Scientific Research Challenging Research (Exploratory)

    Shrews are unique mammals that have poisons in saliva, and it has been suggested that their muscle tissue contain insect repellent substances, and the odor glands contain odorants that repel large mammals. In this study, we aimed to discover novel functional substances related to predation derived from shrews, and to understand their roles in evolution. The enzymatic activity of salivary gland extracts were evaluated, and we established the presence of several serine proteases related to blood coagulation, such as kallikrein, plasmin, and thrombin. In addition, the volatile components contained in the odor grands were analyzed by GC-MS or other methods, and a macrolactone known as a musk odor substance was identified. In the future, we will synthesize the identified compounds, confirm their activities, and elucidate their physiological functions.
