Urban spatial heterogeneity shapes the evolution of an antiherbivore defense trait and its genes in white clover
Tomoki Ishiguro, Marc T. J. Johnson, Shunsuke Utsumi
Oikos, 2024, 2, Wiley, 19 Dec. 2023
Scientific journal, Urbanization is a global threat to biodiversity due to its large impact on environmental changes. Recently, urban environmental change has been shown to impact the evolution of many species. However, much remains unknown about how urban environments influence evolutionary processes and outcomes due to the non‐linearity and discontinuity of environmental variables along urban–rural gradients. Here, we focused on the evolution of hydrogen cyanide (HCN) production and its components (presence/absence of cyanogenic glycosides and the hydrolytic enzyme linamarase) in the herbaceous plant white clover Trifolium repens, which thrive in both urban and rural areas. To comprehensively elucidate how plants evolve and adapt to heterogenous urban environments, we collected 3299 white clover plants from 122 populations throughout Sapporo, Japan. We examined the spatial variation in environmental factors, such as herbivory, sky openness, impervious surface cover, snow depth, and temperature, and how variation in these factors was related to the production of HCN, cyanogenic glycosides, and linamarase. Environmental factors showed complex spatial variation due to the heterogeneity of the urban landscape. Among these factors, herbivory, sky openness, and impervious surface cover were highly related to the frequency of plants producing HCN in populations. We also found that impervious surface cover was related to the frequency of plants producing cyanogenic glycosides, while herbivory pressure was not. As a result, the cyanogenic glycoside frequency showed a clearer trend along urban–rural gradient rather than HCN frequency, and thus, the predicted spatial distributions of HCN and cyanogenic glycosides were inconsistent. These results suggest that urban landscape heterogeneity and trait multifunctionality determines mosaic‐like spatial distribution of evolutionary traits.

English, Scientific journal, Interactions between plants and herbivores are central in most ecosystems, but their strength is highly variable. The amount of variability within a system is thought to influence most aspects of plant-herbivore biology, from ecological stability to plant defense evolution. Our understanding of what influences variability, however, is limited by sparse data. We collected standardized surveys of herbivory for 503 plant species at 790 sites across 116° of latitude. With these data, we show that within-population variability in herbivory increases with latitude, decreases with plant size, and is phylogenetically structured. Differences in the magnitude of variability are thus central to how plant-herbivore biology varies across macroscale gradients. We argue that increased focus on interaction variability will advance understanding of patterns of life on Earth.

When to help juveniles, adults, or both: analyzing the evolutionary models of stage-structured mutualism

Frontiers in Ecology and Evolution, 11, Frontiers Media SA, 19 Jun. 2023, [Peer-reviewed]
Scientific journal, Mutualism is common in nature and is crucial for population dynamics, community structure, and ecosystem functioning. Studies have recently pointed out that life-history stage structure (e.g., juveniles and adults) is a key factor to better understand the ecological consequences of mutualism (termed stage-structured mutualism). Despite the potential importance, little is known about what kinds of stage-structured mutualism can evolve and when it is likely to occur. Here, we theoretically investigated how a mutualistic partner species should allocate efforts of mutualistic associations for different life-history stages of its host species to maximize its fitness. We assessed the partner’s optimal strategy by using a one host–one partner model with the host’s juvenile-adult stage structure. The results showed that different forms of stage-structured mutualism can evolve, such as juvenile-specialized association, adult-specialized association, and inter-stage partner sharing (i.e., the partner associates with both the juvenile and adult stages of the host) depending on the shape of association trade-off, i.e., how much association with one stage is weakened when the partner strengthens its association with the other stage. In general, stage-specialized association (either juvenile-specialized or adult-specialized association) tends to evolve when being associated with that stage is relatively beneficial. Meanwhile, when the association trade-off is weak, inter-stage partner sharing can occur if the mutualistic benefits of juvenile-specific and adult-specific associations are sufficiently large. We also found that when the association trade-off is strong, alternative stable states occur in which either juvenile-specialized or adult-specialized associations evolve depending on the initial trait value. These results suggest that pairwise interspecific mutualism is more complicated than previously thought, implying that we may under-or overestimate the strength of mutualistic interactions when looking at only certain life-history stages. This study provides a conceptual basis for better understanding the mechanisms underlying ontogenetic shifts of mutualistic partners and more complex mutualistic networks mediated by the life-history stages of organisms and their stage-structured interactions.

Scientific journal, Abstract

Precipitation‐induced landslides, which are predicted to increase under the changing climate, may have large impacts on insect community properties. However, understanding of how insect community properties shift following landslides remains limited because replicated research involving landslides, which are large‐scale disturbances with stochastic natural causes, is difficult. To tackle this issue, we conducted a large‐scale field experiment by artificially causing landslides at multiple sites. We established 12 landslide sites, each 35 m × 35 m, and 6 undisturbed sites in both planted and natural forests and collected ground‐dwelling beetles 1 year later. We found that forest type (i.e., pre‐disturbance vegetation) did not affect the structure of a ground‐dwelling beetle community disturbed by a landslide (landslide community), but the structure of an undisturbed community was affected by forest type. Moreover, the structures of landslide and undisturbed communities were completely different, possibly because landslides create harsh environments that act as an ecological filter. Thus, a niche‐selection process may have a critical role in community assembly at landslide sites. There were no significant differences in species diversity between undisturbed and landslide communities, suggesting that landslides to not reduce species richness overall. However, among‐site variability in species composition was much greater at landslide sites than at undisturbed sites. This result suggests that stochastic colonization predominated at the landslide sites more than undisturbed sites. Synthesis and applications. Overall, our results suggest that both deterministic and stochastic processes are critical in community assembly, at least in the early post‐landslide stage. Our large‐scale manipulative field experiment with replications has thus resulted in new insights into biological community properties after a landslide.

Community assembly in plant-bacterium symbiotic interactions in a natural environment: Does host genetic variation matter?
Shinnosuke Kagiya, Ken-ichi Kucho, Shunsuke Utsumi
Authorea, Inc., 24 Sep. 2021
Scientific journal, Community assembly of diverse mutualistic symbionts in host plants have
recently received much attention. On the other hand, for decades,
researchers have also focused on a role of genetic variation for shaping
ecological communities. However, it remains unclear how local
interaction networks between a host and symbionts are shaped from the
pool of genetically diverse microorganisms in the natural rhizosphere.
In this study, we comprehensively analyzed local and regional genetic
communities of Frankia in host individuals and in surrounding
soils using metabarcoding to unravel community assembly in shaping
interaction networks between plants and root nodule symbionts, both of
which are genetically diverse, in natural ecosystems. We found that
Frankia communities in rhizosphere soil were consisted of
tremendously diverse strains. The diverse Frankia communities in
rhizosphere soils were heterogeneously structured by the presence of
host individuals and soil nutritional status. Furthermore,
quantification of the filtering forces by community analysis
demonstrated that the filtering forces that shape symbiotic networks
would depend on genetic variation in the host plant. This study suggests
that filtering mechanisms and host genetics would have a profound role
in shaping plant-bacterium symbiotic networks in natural environments.

Japanese Journal of Conservation Ecology, 25, 2, n/a, The Ecological Society of Japan, Dec. 2020, [Peer-reviewed], [Last author]
Japanese, Research has shown that evolution occurs on the same timescales as changes in population size, and that gene frequency and population dynamics interact with each other. A growing recognition of such eco-evolutionary dynamics highlights a need to study how ecological and evolutionary interactions play out on timescales most relevant to conservation and management. However, the roles of evolution in the outcomes of conservation and ecosystem management are not well understood. This review aims to illustrate the importance of considering evolutionary perspectives in conservation ecology when faced with anthropogenic environmental changes such as climate change, habitat fragmentation, and alien species. We describe the fundamental processes underlying evolution and discuss how evolutionary approaches affect conservation outcomes, as well as specific measures and future prospects for improving conservation and ecosystem management.

Scientific journal, We studied movement of a native salmonid, white-spotted char (Salvelinus leucomaenis), in a 1-km tributary in northern Hokkaido, Japan, in May–July 2018. Based on physical mark–recapture of 501 unique individuals and detection by mobile PIT antenna over monthly intervals, a majority of fish (70%–80%) stayed within 60 m of previously released locations, demonstrating what appeared to be restricted movement patterns. However, fixed PIT antenna data showed that as much as 17% of marked individuals emigrated from the study area during the 2-month study period. Probability of emigration did not depend on where in the 1-km segment individuals had been released, indicating that emigration likely represented long-distance movement. Once emigrants made a decision to emigrate, they left the tributary within 1–3 median days by moving downstream in a unidirectional manner, based on detections at a total of three antenna arrays deployed throughout the tributary. Our multiscale analysis provided strong support for co-existence of short- and long-distance movement patterns, and we conclude that movement data at multiple spatial scales complement each other to characterize population-scale movement.

気候変動に伴う温暖化の進行による生物の絶滅リスク上昇が懸念されている。温暖化に対する生物応答として、分布シフトとフェノロジー変化の二つがもっぱら注目されてきたが、近年、第三の応答として体サイズ変化（特に、体サイズ減少）が指摘されている。体サイズは基盤的な機能形質であり、その応答パターンや変化のメカニズムを明らかにしすることは、生物個体群の存続可能性と絶滅リスクの予測に対して重大な意義を持つ。しかし、温暖化進行下の野外における体サイズ変化を調べた先行研究では、群集レベルあるいは種間レベルの応答に焦点をあてることが多く、種内変異が考慮されておらず、体サイズ変化が迅速な進化による応答なのか、あるいは可塑的応答なのかといった根本的メカニズムの解明に繋がる知見は乏しい。また、これまで体サイズ変化は、気温上昇下での一貫した線形的変化が仮定されてきた。しかし、可塑的応答と進化的応答の交絡、そして、急激な気候変動による複合的な環境因子の交絡によって、体サイズの時間変化は非線形的である可能性がある。以上を踏まえると、気候変動による生物適応動態のメカニズムの解明と適切な将来予測を目指すためには、まずは種内レベルでの形質応答パターンの時空間動態を明らかにする必要がある。そこで今年度は、日本各地で過去20年にわたって標本が収集されてきたクロツヤヒラタゴミムシに着目し、体サイズの時空間動態を解明することを目的とした。特に、1）線形的な体サイズ減少傾向はみられるのか、2）局所集団間で体サイズ動態は異なるのか、を検討した。北海道から和歌山にかけた5地点の解析結果より、温度上昇に対して非線形的な体サイズ変化が示された。また、標本からのDNA抽出を行うとともに、生体からのDNA抽出を行い、HiSeqシーケンスとNanoporeシーケンスを実施して、リファレンス配列を取得した。

複数都市において都市中心から郊外にかけて様々な地点で採集したシロツメクサのジェノタイピングを行った。札幌や旭川ではシアン化水素生成能について明瞭な都市進化が見られることが分かった。一方、釧路や函館でも同様の傾向であったものの空間構造は弱かった。都市化の進行度、および、都市中心から郊外にかけての環境勾配の大きさの違いによるものと考えられた。すなわち、都市化の進行が平行的に都市進化を促進することが、包括的な空間解析によって明らかになった。さらに、このように平行的に生じる都市進化が、シロツメクサに訪花するハチ類の行動への波及性について人工蜜を作成し実験的に検証した。その結果、郊外由来ハナバチはシアン配糖体を含有する蜜もそうでない蜜も選好性を示さなかったが、都市部由来のハナバチはシアン配糖体を含有する蜜に対して選好性を示した。進化的な応答なのか、学習によるものなのかはまだ分かっていないが、植物の都市進化が送粉昆虫の行動に影響を及ぼすという新規な知見が得られた。
また、環境DNAを活用した野外での生態ー進化動態の観測においても重要な発展が得られた。６月から１０月にかけての毎週の調査によって環境DNAを取得し、メタバーコーディングによって樹上の節足動物群集の構造についてのデータが得られた。さらに同時に、核ゲノムにおける一塩基多型についてもデータの収集ができ、そのアリル頻度に関する時系列データが得られた。このように、環境DNAによって種レベルの多様性情報と、アリル頻度という種内レベルの多様性情報を高頻度で同時に得られたことはきわめて新規性が高い。しかも、時系列モデリングによる因果推論によって、節足動物群集の動態がアリル頻度の時間変化を駆動することが示された。これは、群集が迅速な進化を駆動する証拠であるとともに、昆虫の実サンプルを収集して示された生態ー群集動態のパターンとも合致する。

生態系復元実験のために、北海道大学雨龍研究林・中川研究林・天塩研究林の３地域において、大規模な山腹崩壊を模した実験地を造成することができた。本年は、その実験地における研究を開始することができた。実験地は、各林に35ｍ四方のサイトが５か所で、合計１５か所である。
まず、北海道の異なる地域から昨年度中に集めておいた樹木の種子（ケヤマハンノキ・ダケカンバ・イタヤカエデ・トドマツ）を用いて、2021年6月に播種を行った。このとき、遺伝的多様性の操作（種子の由来地域における単独と混合）と種多様性の操作（単種と４種混合）のすべての組み合わせで処理区を設定し（20処理区）、各サイトに３つの反復を設けた。すなわち、合計900区画の播種実験を行った。秋にまず最初の発芽状況の調査を行った。
次に、大規模撹乱に対する節足動物群集の新たな形成過程を実験的に検証するため、上記の実験地を活用して、地上徘徊性昆虫の調査を行った。実験地を山腹崩壊処理区とし、隣接する天然林・人工林を対照区として、地上徘徊性昆虫群集の撹乱応答を比較した。その結果、処理区と対照区では、群集の種組成がまったく異なることが分かった。さらに、処理区では各サイト間での組成の変異性（β多様性）が対照区と比較してきわめて高いことが分かった。すなわち、大規模撹乱が生じた際には、森林内に生息する昆虫種は定着できず、周囲の撹乱地をハビタットとするような種が移入すること、その移入には確率性も大きく貢献していること、という過程を通して群集が形成されることが分かった。そしてこの移入が機能しない場合には、多様性回復は遅くなることが示唆された。
さらに、植物上の陸域昆虫群集について環境DNAによる調査を行った。それにより、環境DNAによって、植物上の陸域昆虫群集の種組成や多様性を調べることが可能であることが新たない明らかになった。

豪雨などによる山腹崩壊後の森林の生態系機能を効率的に回復させる上では、森林植生を速やかに回復させる植林技術の開発が鍵になる。特に、広範囲で適応可能な山腹崩壊後の植生回復指針を確立するためには、多様な立地環境において発生した山腹崩壊地を対象に、 環境特性にあった植栽樹種を明らかにすることが有効である。山腹崩壊跡地では、しばしば窒素固定植物が植栽された際に高い生存率・成長率を示すことが知られているが、多様な窒素固定植物の中でも、どの樹種が、どのような立地で発生した山腹崩壊跡地への生存に適しているかは明らかにされていない。そこで本年は、前年に多様な立地環境に人工的に作成した15箇所の人工山腹崩壊試験地に植栽していた北海道に自生する2種の窒素固定植物（ヤマハギおよびケヤマハンノキ ）について、その生存率と環境要因の関係を検証した。
環境条件を調査した結果、15箇所の山腹崩壊跡地では、斜面の斜度が急になるとともに、土壌含水率は低下し、表層土砂の流出量は増加した。一方、斜面の斜度が急になるとともに、エゾシカの発見頻度は低下した。植栽木については、同じ窒素固定植物であっても、ヤマハギとケヤマハンノキでは、ケヤマハンノキの方が山腹崩壊跡地の生存率は高いことがわかった。また、２種間で生存率へ影響する立地環境は異なり、ヤマハギへは土壌の母岩の違いが、ケヤマハンノキへは崩壊地の斜度、土壌の粒径、土壌含水率が影響を及ぼしていた。興味深かったのは、ケヤマハンノキの生存が、斜度が急な立地で生存率が高かったことである。急傾斜地へ植栽したケヤマハンノキが高い生存率を示したことについては、近年増加しているエゾシカによる食害が急傾斜地では起きにくいことが関係していることが考えられた。

気候変動・生息地断片化・外来種などの人間活動に関連する環境変化が深刻さを増しており、それによる生物の絶滅が急速に進行している。それに対し、環境ストレスに適応する、野外生物の迅速な進化によって絶滅が回避される進化的救助という新しい理論が注目を集めている。進化的救助とは、環境ストレスに対する生物の迅速な適応進化のポテンシャルを予測し、自然生態系における適応進化を制御することを通して、野外生物の保全に繋げようというこれまでに人類が成したことのない新しい挑戦である。しかし実践は容易ではない。そもそも自然生態系での実験検証が困難であり、それが進化的救助の研究の進展を妨げている。そこで本提案は、ミュゼオミクスという新興アプローチからこの分野のブレークスルーを起こそうというものである。博物館の自然史標本の生化学・分子情報を網羅的に抽出し、それにより進化史や遺伝的多様性の変遷などを推定しよういうのがミュゼオミクスである。本研究は、広域長期モニタリングによって集積された標本を対象とすることによって、集団や群集という個体よりも上位の生物階層パラメータまでも紐付けた新規なミュゼオミクスに取り組む。すなわち、過去から現在までの地球気候変動（気温上昇）・適応的な対立遺伝子頻度の変化・集団サイズの変化の３つを関連付けて解析することによって、野外生物における進化的救助の実態と意義を世界に先駆けて明らかにすることが目的である。
本年度は、この目的に対する基礎的な準備を進めた。まず、野外調査により、クロツヤヒラタゴミムシ野外個体の採集と飼育を行い、ロングリード解析の基礎となる良質で大量のゲノムDNAの抽出をすることが出来た。また、クロツヤヒラタゴミムシの標本の一部からDNA抽出を試みた。標本からのDNA抽出は部分的に成功し、標本の年代が古くなるほど抽出できる量は少なくなる傾向にあることがわかった。

In this research project, we examined the causes and consequences of temporal variation in subsidies in stream and riparian ecosystems. A large-scale monitoring revealed that phenological diversity of arthropods and their nematomorph parasites synergistically determined the duration and seasonal timing of the riparian subsidies into streams. A field experiment then revealed that the pulsed subsidy allowed salmonid fish grow more evenly among individuals, which had different cascading effects on benthic invertebrates and leaf breakdown rate compared with the prolonged subsidy. In another experiment, fish exhibited a higher numerical response to the early subsidy, but not to the late subsidy, with the timing-dependent life history adoptions and its diversity. By using these empirical results, two modeling approaches highlight underappreciated roles of phenological variation in the assemblages of across-habitat consumer and resource movements in driving community and disease dynamics.

The aim of this study was to examine how complex ecological community and rapid evolution of community members influence each other in the field. I constructed large mesocosms covering mature willow trees, and performed manipulative experiments with insect communities and one of the dominant herbivorous insects, the willow leaf beetle, Plagiodera versicolora. In the leaf beetle, a foraging trait has genetic variation (i.e., specialist which exclusively feeds on new leaves and generalist which show non-preference for leaf-age types). I inoculated leaf beetles populations into the mesocosms by the following three ways: specialist only, generalists only, and both types). As a consequence, community structure of diverse insect species differentially developed on a tree crown, according to the beetle treatment. Furthermore, community divergence could feed back to rapid evolution of the foraging trait of the leaf beetle.

Effects of aphid and lacebug herbivory on reproductive success and flower visitor communities on tall goldenrods were investigated. Lacebug herbivory decreased flower number and floral nectar. In contrast, aphid herbivory increased them. Increased flowers increased abundance of pollinators and non-pollinators. Lacebug herbivory decreased seed production, while aphid herbivory increased it. Origin of Japanese goldenrods was explored using neutral genetic marker. We found that Japanese goldenrods came from Southeastern United States, and that genetic diversity has been maintained through gene flow since their establishment in Japan. Effects of diversity and selection in goldenrod genotypes from Honshu and Hokkaido were investigated. Although we did not find the diversity effect on plant growth, the selection effect in Hokkaido genotypes was detected. The diversity effect of plant genotypes was also found in aphid abundance.
