Journal of Animal Ecology, Wiley, 17 Mar. 2026, [Peer-reviewed]
English, Scientific journal, Abstract

Predator–prey interactions have long been recognized as important selective forces in the evolution and maintenance of multiple traits in both predators and prey. Certain animal species leave information intentionally or unintentionally, in the form of urine, faeces, feeding traces and chemical trails, even after they have moved. This residual information, left behind by animals, has the potential to affect predation efficiency. However, information warfare—the use of information between predator and prey, in which predators exploit prey cues to increase predation efficiency, while prey exploit predator cues to reduce it—remains largely unexplored, especially in the context of residual information.

Marine gastropods leave a mucus trail that contains individual information as they crawl. In this study, we investigated the existence of information warfare between the predator snail Reishia clavigera and the prey limpet Siphonaria sirius through mucus trails. We observed the responses of predators and prey to their respective mucus trails under laboratory conditions.

The predators followed the prey's mucus trails. In contrast, the prey exhibited movements, such as looping, upon confrontation with the predator's mucus trails. The looping behaviour reduced the probability of the predator reaching the endpoint of the prey's mucus trail.

These results suggest a potential strategy whereby predators exploit prey mucus trails for localization, along with a counter‐strategy through which prey minimize the risk of detection. Our findings provide novel insights into how information shapes predator–prey interactions, indicating the potential existence of an information‐induced arms race.

English, Scientific journal, Abstract

The impacts of large‐scale disturbance events on the species diversity of rocky intertidal sessile assemblages across multiple spatial scales are not well understood. To evaluate the influence of the 2011 Tohoku Earthquake on alpha and beta diversities of rocky intertidal sessile assemblages, we surveyed sessile assemblages in the mid‐shore zone from 2011 to 2019 and compared the data with those collected from 2003 to 2010 before the earthquake at the same region. The census was conducted across 22 study plots on five rocky shores along 30 km of the Sanriku Coast of Japan, which is located 150–160 km north–northwest of the earthquake epicenter. Alpha diversity was measured with three Hill numbers (H₀, H₁, and H₂), which represent the number of equally common species that would exist in a community with the same diversity as the sampled community, with higher values of the subscript indicating more weight placed on abundant species. Beta diversity was measured with two metrics (BD_total at two spatial scales). Values were compared between the post‐earthquake period (2011–2019) and the pre‐earthquake period (2003–2010). The results show that the Tohoku Earthquake significantly altered the species diversity of intertidal sessile assemblages across multiple spatial scales. All diversity metrics obtained at multiple spatial scales (i.e., alpha diversities: H₀, H₁, and H₂; beta diversities: BD_total at the shore and regional scales) decreased immediately after the earthquake and then increased in subsequent years. At 2 years after the earthquake, H₀ recovered to within the range of pre‐earthquake values and H₁ and H₂ became significantly higher than pre‐earthquake values. Most metrics of alpha and beta diversities recovered to pre‐earthquake levels after several years, but regional BD_total remained low for a longer period., 41924698

Immediate Impact of the 2021 Harmful Algal Bloom in Southeast Hokkaido on the Rocky Intertidal Benthic Community and Its Spatial Variation
Yuan Yao; Takashi Noda
Journal of Marine Science and Engineering, 12, 6, 928, 928, MDPI AG, 31 May 2024, [Peer-reviewed], [Last author]
English, Scientific journal, There has been a limited number of studies on the effects of harmful algal blooms (HABs) on natural rocky intertidal ecosystems. From mid-September to early November 2021, an unprecedented HAB caused by Karenia selliformis hit the Pacific coast of southeast Hokkaido, Japan, for the first time, causing massive mortalities among marine organisms. To clarify the immediate impacts of the HAB on the abundance of 10 rocky intertidal species in four functional groups (macroalgae, sessile invertebrates, molluscan grazers, and molluscan carnivores), we focused on two questions: (1) How did the HAB affect the abundance of each species differently at the regional scale? and (2) How did the impacts of the HAB on the abundance of each functional groups vary spatially, and was the spatial variation of the HAB impacts related to the spatial distribution of the cell density of HAB species? To study these issues, we compared census data for 17 years before the HAB and within one month after it for five shores on the southeast coast of Hokkaido. The results showed that two macroalgae species and all three molluscan grazer species declined significantly after the HAB. Moreover, the decrease in molluscan grazers was significantly correlated with cell density. These results suggest that the impacts of the HAB in southeast Hokkaido on the abundance of rocky intertidal organisms are highly variable depending on species and locality, presumably because of differences in species-specific tolerances to HAB toxins and the spatial variation in the density of the HAB organisms., 41924698

English, Scientific journal, Abstract

The effects of seed dispersers on plant fitness (seed dispersal effectiveness, SDE) have been evaluated based on the number (quantity) and recruitment probability (quality) of dispersed seeds. Although seeds of most zoochorous species are dispersed by two or more animal species, which may interact with each other, SDE has often been studied assuming a one-plant and one-animal species system. We compared the SDE of Japanese walnut (Juglans ailanthifolia) between squirrel-only and squirrel-mouse sites in natural forests of Hokkaido, Japan, and found that the SDE from the red squirrel (Sciurus vulgaris), considered a primary seed disperser, was altered by an alternative seed disperser species, the Japanese wood mouse (Apodemus speciosus). Seed removal rates at the squirrel-mouse site were significantly higher than those at the squirrel-only site, and both dispersed seeds and seedlings were less aggregated, with a strongly repulsive relationship with adult conspecific trees at the squirrel-mouse site. Seedlings established themselves at a location with fewer medium-sized trees (< 10 cm DBH) at the squirrel-mouse site. These results suggest that the interactive effect of the rodent species affects the SDE of Japanese walnut.

English, Scientific journal, The frequency and duration of marine heat waves (MHWs) have recently increased. There is therefore an urgent need to understand the response of marine organisms to MHWs. However, most estimates of MHW impacts on abundances include the effects of environmental stochasticity other than the MHWs. In addition, although MHWs sometimes persist for year-round or occur repeatedly for shorter periods, the accumulative carryover effects (ACEs)— the effects of sequential events accumulating additively over time— of MHWs on organisms have never been evaluated. Furthermore, the relationship between species niche traits other than thermal niches and susceptibility to MHWs is unknown. We examined the impacts of MHWs in southeastern Hokkaido, northern Japan, in summer from 2010 to 2016 on rocky intertidal communities by distinguishing MHW effects from environmental stochasticity. We asked (1) Did MHWs have ACEs on four major functional groups: macroalgae, sessile invertebrates, herbivorous invertebrates, and carnivorous invertebrates? (2) Does ignoring ACEs lead to biased assessments? (3) How did the effects of the MHWs on functional groups and their subsequent recovery differ? And (4) How does the susceptibility to MHWs differ with species niche (thermal and vertical) traits? We detected ACEs of MHWs and found that if they are ignored, the effects of MHWs can be underestimated. Although MHWs are known to reduce the abundance of macroalgae and increase that of sessile invertebrates in rocky intertidal habitats, our results show that macroalgal abundance increased during and after MHWs, whereas sessile invertebrates showed no change during or after MHWs. The abundance of herbivorous mollusks decreased during and after MHWs. Carnivorous invertebrates declined during MHWs and in the first year after MHWs. During and after MHWs, abundances of species with low thermal niches decreased and those with high thermal niches increased. There were no differences in response to MHWs between vertical niches when accumulative carryover effects were ignored. These results emphasize the importance of considering ACEs when assessing the response of marine organisms to MHWs, and that more studies of these responses are needed for a variety of ecosystems, regions and organisms to predict the responses of marine organisms.

English, Scientific journal, Long-term patterns in trajectories of natural communities provide insights into ecological resilience, but their assessment requires long-term census data. We analyzed 16-year census data for intertidal communities from 30 rocky shores along Japan’s Pacific coast to assign community change to four possible trajectories (stable, reversible, abrupt, or linear) representing different aspects of ecological resilience, and to estimate multiple metrics of temporal invariability (species richness, species composition, and community abundance). We examined (1) how the prevalence of the four trajectories differs among regions, (2) how the features (model coefficients) of each trajectory vary among regions, and (3) how the temporal invariabilities differ among trajectories and regions. We found that the stable trajectory was the most common. Its features differed among regions, with a faster recovery to steady-state equilibrium in low-latitude regions. Furthermore, trajectories and temporal invariabilities both varied among regions, seemingly in association with the strength of ocean current fluctuations. Thus, the relationship between community temporal invariability and trajectory may be weak or absent, at least at the regional scale., 11970374

English, Scientific journal, By analyzing data obtained from 23 plots on five shores along the Pacific coast of Japan over 7 years, we explored theinfluence of the 2011 Tohoku Earthquake on the population dynamics of a rocky intertidal barnacle, Chthamalus challengeri. Weaddressed the following three questions. (1) At local and intermediate scales, how did the spatial patterns of larval recruitmentchange after the earthquake? (2) At broader spatial scales encompassing the entire meta-population, did larval recruitmentchange with the alteration of stock size after the earthquake? (3) How did the relative importance of larval recruitment as a determinantof local population growth rate change after the earthquake? The results demonstrated that while the spatial patternof C. challengeri larval recruitment was only slightly modified by the 2011 earthquake, the population dynamics were significantlychanged immediately (1–2 years) after the earthquake at two contrasting spatial scales. At a broad spatial scale encompassingseveral bays, the population size increased, consequently enhancing recruitment intensity, whereas at the local scale,the dependence of local population growth rate on larval recruitment increased. The former finding contradicts a widelyaccepted assumption that severe physical disturbances occurring at a broad spatial scale heavily impact natural populations.Special Issue（東日本大震災特集）

近年、地球規模での生物多様性の減少が問題となっている。生物多様性を保全する理由のひとつとして、生物多様性と生態系機能に正の相関があることが指摘されている。このことは最近の群集生態学における大きなテーマのひとつであり、草原や微生物群集を対象に研究が進んでいる。しかし両者の関係が野外生物群集一般に適用できるかどうかは不明である。特に環境要因の変異や空間スケールの差異が与える影響については十分に検討されていない。そこで本研究では岩礁潮間帯生物群集を対象に、複数の空間スケールを階層的に配置した研究デザインによりその関係性を解析した。
日本の太平洋側の6つの地域(道東、道南、三陸、房総、南紀、大隅)において、地域内に5海岸、さらにその海岸内に５測点を選定した。各測点で岩礁潮間帯のほぼ垂直な岩盤上で平均潮位の上下それぞれにコドラート(50cm×50cm)を設置し、各コドラート内の100の格子点を占有する種の変遷と潮位ごとでの全出現種を記録した。計300コドラートの2003年春から2004年春への1年間のデータの推移を基に解析を行った。本実験での生物多様性とは、種多様性を意味し、_丸1_Simpsonの多様度指数、_丸2_全出現種数の２つを空間スケールごとに求めた。また生態系機能の指標としては、_丸1_現存量(2004年の被度)_丸2_安定性(2003-2004年の被度の変化_丸3_抵抗性(2003年は生物だった点が2004年に裸地にならない割合_丸4_回復性(2003年は裸地であった点が2004年に生物になる割合)を求めた。これらについて空間スケールごとに相関解析を行った。また、環境要因をとりいれた多変量解析を行い、環境要因と種多様性が生態系機能に与える相対的重要性を検討した。

Holocene Fluctuation of the Warm Tsushima Current and Warm Molluscan Assemblages from Hokkaido, Japan
Norio Kito; Takashi Noda; Toshitaka Minami
The Quaternary Research, 37, 1, 25, 32, Japan Association for Quaternary Research, 1998
Japanese, A molluscan assemblage including warm water species such as Meretrix lusoria, Mactra veneriformis, Umbonium moniliferum, etc., found in the Hakodate Plain was dated 2, 400-2, 300yrs BP by the ¹⁴C method. This age is younger than the known warm Jomon transgression (Flandrian transgression) period. Based on the newly dated assemblage, three stages of Holocene warm assemblages are recognized from southern Hokkaido: 7, 500yrs BP, 4, 000yrs BP, and 2, 400-2, 300yrs BP. These stages are concordant with three periods of strong northward inflow of the warm Tsushima Current. Warm molluscan assemblages probably extended their geographical range to Hokkaido three times synchronously with strong inflow of the current.

Japanese, Seasonal patterns in growth of shell and soft part weights were investigated for small (immature) and large (mature) individuals of the supralittoral snail, Nodilittorina exigua at Kattoshi, southern Hokkaido. Shell growth was measured monthly for marked animals. Soft part weights of the marked animals were calculated by allometric equations between shell height and dry flesh weight that derived from 50 unmarked individuals for each month. Shell growth of both small and large snails occured only in summer, and growth rate and growth period of large snails were lower and shorter than those o...

BENTHOS RESEARCH, 42, 0, 39, 48, JAPANESE ASSOCIATION OF BENTHOLOGY, 31 Jan. 1992
Japanese, Monthly measurement of growth rings along the shell margin of the North Pacific cockle Clinocardium californiense revealed that a ring is formed annually in September (above one year-old) or in October (0 year-old), when the bottom temperature is high. Age was determined by counting the number of growth rings on the shell. The VON BERTALANFFY growth equation was fitted to the age-shell length relation, and the equation, L_T=57.14(1-exp(-0.526(T-0.143))) is obtained, where L_T is the shell length (mm) at age T (year). Seasonal growth pattern was estimated by measuring the monthly shell increment from the last growth ring, and the equation obtained is L_T=57.35[1-exp(-0.522(T-0.241)+0.085sin(2π(T-0.476)))]. These equations show nearly the same growth rates with those previously reported for cardiid cockles, but are higher than those for other bivalves.

地球規模で環境変化が進行しつつある現在、生態系の変化を予測することは生態学に課せられた最大の課題である。本応募研究では生態系の数十年の変化の予測可能性を評価するための新たな研究フレームを提案し、これを岩礁潮間帯生態系に適用する。太平洋沿岸の6地域×5海岸×5岩礁の計150岩礁において、遷移区（人工裸地）とその対照区（無操作区）で集積した25年間の肉食者、植食者、固着動物、底生藻の4機能群の各種のアバンダンスデータを用いて様々な生態系属性を求める。得られた生態系属性とその安定性の約20年後の予測可能性を評価する。
本年度は，遷移区の再設置とその対照区での野外調査を行った．太平洋沿岸の6地域（北海道東部，北海道南部，三陸，房総半島，南紀，大隅半島）の5海岸、各海岸の5岩礁の計150岩礁のうち，大隅の2海岸を除く海岸において，自然撹乱を模した遷移区（人工裸地）を再設置した．再設置した遷移区の設置時期（季節），設置方法，位置およびサイズは，最初に設置した2002年の時と完全に一致するように行った．また，対照区での野外調査は，これまでの長期センサスと全く同一の調査項目について例年同様に夏季に行った．
加えて，すでに蓄積されている長期センサスデータを用いて予備解析を行った．北海道東部の21年間の岩礁潮間帯生物群集の主要機能群（底生藻類，固着動物，植食性動物，肉食性動物）を対象に地域スケールでの機能群アバンダンスと種アバンダンスについてトレンド解析を行った．その結果，機能群レベルでも種レベルでも，一部の対象において有意な時間傾向が検出された．

Effects of intra-specific variation on the coexistence of sessile organisms evaluated by long-term observation
Grants-in-Aid for Scientific Research
01 Apr. 2018 - 31 Mar. 2021
Kohyama Takashi
Large within-species variation is observed in sessile organisms, such as forest trees, shrubs and intertidal barnacleｓ. Dealing with those systems consisted of multiple species, this study examined the relationship between within-species, among-individual variations of life-history measures (in particular, size-dependent growth) and among- species coexistence. We quantified within-species variation using long-term repeated census records, applying bias-free new methods. Life-long integration of variation characterized species-level turnover rates. The fast-slow trade-off among species facilitated the equitability mechanism of coexistence.

Recovery of rocky intertidal community after the 2011 Great East Japan Earthquake elucidated by a large-scale longterm community census
Grants-in-Aid for Scientific Research
2015 - 2017
NODA Takashi
The 2011 Great East Japan Earthquake caused large tsunami and coseismic subsidence in the Tohoku region. To assess impacts of the earthquake on rocky intertidal community and the course and status of recovery of the community by before/after comparison, I carried out the survey using the same method at the same place from 2011 to 2017. The results show that the rocky intertidal community suffered significant but only relatively minor damage from the tsunami. In contrast, coseismic subsidence may have caused the considerable changes in distribution and abundance of organisms. At 6 years after the earthquake, the community has not yet returned to its normal state; for several dominant species, zonation in 2017 was obviously different from zonation before the earthquake. This community will experience a long delay before fully recovering from the impact of the earthquake because species that have not recovered include late successional species.

Impact of the 2011 off the Pacific coast of Tohoku Earthquake on rocky intertidal community elucidated by a large-scale longterm community census

2012 - 2015
NODA Takashi
The 2011 off the Pacific coast of Tohoku Earthquake caused large tsunami and subsidence in the Tohoku region. Before the event, I regularly carried out a rocky intertidal community census for eight years on five shores close to the epicenter of the earthquake. To assess impacts of the earthquake by before/after comparison, I carried out the survey using the same method at the same place from 2011 to 2014. The course and status of recovery of populations substantially varied among species. A barnacle drastically increased and expanded its vertical range in 2011, then decreased. Other sessile species shifted their zonations downward according to the subsidence in 2011. Some of them did not clearly change their abundances light after the earthquake but increased and moved upward, while others continuously decreased. All mobile species did not clearly change their vertical distributions light after the earthquake. Among them two species decreased from 2012 and not recover.

To provide scientific information for the conservation and management of coastal ecosystems and resources, the present study carried out an integrated approach to investigate structure and dynamics of coastal marine community and their changes in relation to global climate change such as temperature rise. We specially targeted on seagrass bed, rocky intertidal and kelp forest communities as model systems. We conducted broad-scale, long-term monitoring of these communities based on periodical census and the use of remote sensing and GIS analyses, statistical analyses on meta-community structure, genetic analyses based on molecular data, and field manipulative experiments. The results demonstrated that structures of coastal communities are affected by multiple factors that operate at different spatial scales, and that their dynamics can be unstable with ongoing climate change through modification of species interaction processes between producers and consumers.

MINAGAWA Masao; NODA Takashi
To evaluate stability of aquatic ecosystems which are disturbed by interference such as by immigrant biota or by eutrophication, we studied and evaluated here stable nitrogen isotope proxies as a likely indicator assessing the state of nitrogen cycling and food chain structure of an ecosystem. Based on field works at Ishikari river water shed where it has been concerned about large discharge of anthropogenic nitrogenous compounds, and many dam ponds distributed in Toyama prefecture as being concerned about ecological disturbance by large-mouth bass recently. The nitrogen isotope analysis has been clarified as a useful and promising indicator to evaluate environmental problems occurring in ecology and/or nutrient cycling even though based on only snapshot observations.

岩などの硬い基質上をすみかとする底生動物では、加入個体の分布が基質の微小な割れ目に集中することが知られている。しかし、このような特定の微地形への加入個体の集中が水深や加入密度に依存してどのように変化するかは、ほとんど明らかになっていない。そこで、北海道の岩礁潮間帯に生息するキタイワフジツボを材料に、岩表面の割れ目に対する加入個体の集中度が水深、年、加入密度に依存してどのように変化するかを明らかにした。
解析には北海道南部の垂直な岩礁に設置した永久方形枠(縦1m、横50cm)で2004年から2008年の期間に収集されたデータを用いた。方形枠内の岩表面は毎年7月に無生物化し、その3ヶ月後に永久方形区内のさまざまな潮位に設置した80コドラート(各25cm^2)を写真撮影した。この写真を用い、定着個体の分布とその定着場所(岩表面の割れ目とそれ以外)を評価した。
その結果、加入個体が割れ目に集中する程度は高潮位(水深が浅い)ほど高くなることがわかった。また、加入個体が割れ目に集中する程度は、加入密度が高くなるほど低くなることがわかった。さらに、高潮位では、割れ目に見られた加入個体は、割れ目の外の個体より体サイズが大きいことが分かった。
これらの結果は、本種の幼生は定着するときに岩の割れ目を選好するが、その選好性は割れ目の内外で成長量に差の出る高潮位ほど強い可能性を示唆している。このことは、観察された加入個体の割れ目への集中度の潮位による違いは幼生の適応的な定着場所選択の結果である可能性があることを示している。

This study aims to examine the effects of spatial scale on structure, dynamics and diversity of biological communities using rocky intertidal communities as a model system. We established a total of 150 census plots along the Pacific coast of Japan according to nested hierarchical sampling design, and conducted census of community, experiment on succession and monitoring of environmental conditions. Major findings are summarized as follows :1.We found clear latitudinal gradients of regional species richness and species turnover among shores. However, these patterns were not reflected at a s...

An experimental test of the effects of productivity and environmental stress on a rocky intertidal food web
Grants-in-Aid for Scientific Research(基盤研究(C))
2001 - 2002

Food web dynamics can be controlled by both external factors of primary productivity and environmental stress of ecosystem. However, little is know about how these two factors affect the food web dynamics in natural communities. Here I report a field factorial experiment manipulating the nutrient levels (as an external factor controlling primary productivity), and desiccation stress (as a factor of envilonmental stress), and the presence /absence of macrograzer (limpets ; their grazing is a key process in the food web) in a rocky intertidal algae-grazer food web. The results revealed that d...

岩礁潮間帯生物群集におけるトップダウン/ボトムアップコントロールの実験的検証
科学研究費補助金(奨励研究(A))
1999 - 2000

栄養塩レベルの違いが群集内の種の共存や種間関係に及ぼす影響は、古くから生態学者の興味を引いてきたが、これまでの研究の多くは平衡群集における栄養塩レベルの影響に注目したものである。植物が固着性である生息場所では、植物群落は非同調的に生じる撹乱とその後の住み着きと絶滅(パッチダイナミクス)によってその多様性が維持される非平衡な系であることが多い。このような系で、栄養塩レベルが植物同士の共存機構や食物網関係にどのように影響を及ぼすかは良く判ってはいない。北海道南部の岩礁潮間帯中部では、二枚貝のムラサキインコガイが高密度に生息している。ここで競争的優占種であるムラサキインコガイが波により剥がされてできた撹乱パッチ(空き地)には様々な海藻と、これを餌とするグレーザー(マクログレーザーのカサガイとメソグレーザー)が生息している。本研究ではパッチ内に成立するこの群集における栄養塩レベルの影響を明らかにするため、栄養塩供給量とカサガイの密度を実験的に操作し、群集構造の変化を一年間追跡し、得られた結果から、栄養塩レベルが、種間相互作用(グレージングと競争)と、種の住み着きと絶滅率を通して群集構造の時空間変異に及ぼす影響を解析した。その結果、栄養塩添加により、海藻の増殖速度は早くなり海藻間の競争が強くなった。またカサガイが増加し海藻へのトップダウン効果とメソグレーザーに対する排除が強くなった。ま...

【研究目的】岩礁潮間帯では地形構造決定を通して地質が生物群集構造と多種共存機構に及ぼす影響を調べた研究はない。そこで北海道南部で火山岩と火山砕犀岩からなる岩礁海岸のムラサキインコガイ帯で、地質の違いに対応して地形構造と群集構造は異なるか、地質の違いが群集形成作用にどのように影響するか、地質の異なる岩礁海岸で固着生物群集の多種共存メカニズムはどのように異なるか、を明かにすることを目的とした。【平成9年単年度の実績】火山岩と火山砕屑岩からなる11の海岸で地形の複雑さとムラサキインコガイ群集構造を調査した。また各海岸にムラサキインコガイを剥いだ人工パッチを5個つくり、パッチ内の初期遷移と海水成分(栄養塩・chl a)の反復観測を開始した。その結果、火山岩海岸は火山砕犀岩海岸に比べ、1-10cm、1-10m空間スケールでの地形の複雑さが大きく、ムラサキインコガイは少なく、ムラサキインコガイを餌とする肉食性巻貝は多く、また種多様性種数は高いことが明らかになった。このことは火山岩海岸では肉食性巻貝が競争的優位種ムラサキインコガイの競争的排除を抑えることにより多様性が高くなっている可能性を示唆する(key stone predation仮説)。【平成10年度の研究実績】key stone predation仮説を検証するため、4つの火山岩海岸と火山砕犀岩海岸で、肉食性巻貝の密度操作実験を行...
