We then surveyed the existing literature to compile nine important functional traits for each species. The nine selected traits cover information about feeding ecology (feeding guild, feeding source, food acquisition, feeding mode, food specialization), habitat requirements (stratum), flight capability (aerial mobility), and size (body mass, body length). As the selected traits cover both response traits and effect traits, this database can be deployed for investigations on topics ranging from the sensitivity of arthropod communities to environmental changes (response traits) to the impact of arthropods on the functioning of ecosystems (effect traits).

In many mountainous and high-latitude watersheds, streams fed by rain and groundwater sources coexist with streams dominated by meltwater from melting glaciers, permafrost, and seasonal snowpack. The distinct physicochemical regimes of meltwater and non-meltwater fed streams can promote spatial and temporal asynchronies in biotic and abiotic environmental conditions within watersheds that promote ecological heterogeneity and stability. However, fading cryospheric inputs to watersheds threaten to homogenize and synchronize stream habitats and resources. Here, we compared the physicochemical conditions and biomass dynamics of stream food webs (course particulate detritus, periphyton, aquatic invertebrates, and fish) over a meltwater season from April to November in four streams with different predominant sources of runoff, one glacier-fed, one snow-fed, one rain-fed, and one stream transitioning from glacier- and snow-fed to a rain-fed. We then analyzed the temporal correlation (“synchrony”) of the abiotic and biotic conditions in these streams and evaluated how synchrony might change if certain stream types were lost. We found that glacier-, snow-, and rain-fed streams had distinct temperature, flow, and water chemistry regimes and asynchronous seasonal patterns of detritus, biofilm, aquatic invertebrate, and fish biomass. The strongest differences were associated with the divergence of abiotic and biotic conditions in the glacier-fed stream relative to the other stream types. Synchrony analysis suggests that the climate-driven loss of meltwater contributions from the cryosphere may synchronize the seasonal resource dynamics of meltwater and non-meltwater streams during the primary growing season within and across watersheds. Increasing synchrony of abiotic processes that drive instream production could reduce ecological stability within watersheds as seasonal conditions converge, especially for mobile consumers that will lose the opportunity to integrate resource waves across complex landscapes.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"106 4","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To anticipate how communities may respond to future invasions, it is crucial to refine how invader impacts are evaluated, especially in historically uninvaded and highly variable systems such as arid lands. While invader abundance is typically used to predict invader impacts, it may not effectively capture the dynamics that occur over time for established invaders that experience cyclical dynamics (i.e., boom-bust patterns), making it more challenging to track invader impacts. To address this issue, we leveraged a long-term vegetation dataset to develop a novel invasion regime framework for a dominant annual invader in North American deserts, <i>Brassica tournefortii</i>. Using abundance data over time, we evaluated how attributes of this invader's boom-bust dynamics (i.e., invasion level, boom frequency and magnitude) influence the long-term synchrony and stability of invaded Eolian sand dunes communities. We found that attributes that captured the temporal effects of the invader were strong indicators of the impacts of an invader on long-term attributes of communities. Specifically, the mean magnitude of invader booms led to a decrease in species asynchrony and community stability. Increasing boom frequency also decreased community stability, but this was more muted. Mean magnitude of invader booms also mediated shifts in the relationship between synchrony and stability, with this relationship becoming more shallow with increasing boom magnitudes. Our research emphasizes the significance of using community metrics that capture temporal dynamics to document invasion impacts within dynamic arid land systems. The invasion regime framework can additionally offer insights into the mechanisms that may enable the persistence of the invader over time. Together, this knowledge can be helpful in guiding decision-making and land management strategies aimed at effectively controlling and mitigating the impact of invasive species.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"106 4","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, focusing on response traits in multidimensional functional diversity studies limits our ability to make these linkages. We developed a multidimensional analytical and visual stoichiometric diversity framework that links organismal responses to and effects on environmental change using stoichiometric traits. We define these traits as the acquisition, assimilation, allocation, and excretion of key chemical elements by members of an assemblage. We discuss the considerations for using stoichiometric traits in a trait-based framework and apply the framework to case studies of temporal variation in stream benthic invertebrate assemblages and spatial variation in urban woody vegetation assemblages.

Migrating ungulates, in particular, track waves of newly emerging plants from low-elevation winter ranges to high-elevation summer ranges—known as “green-wave surfing.” Because plants lose crude protein and gain insoluble fiber with maturation, ruminants are expected to exploit peaks in forage quality among individual plants (i.e., Forage Maturation Hypothesis). Although ample evidence supports the long-standing hypothesis that migratory ungulates surf peaks in forage quality during migration, the hypothesis that ungulates track peaks in forage quality at a small scale (i.e., microsurf while on summer range) remains less known. We studied a partially migratory population of mule deer (<i>Odocoileus hemionus</i>) in Wyoming, USA, to understand whether temperate ungulates optimize the use of high-quality forage as plants grow and senesce on disparate summer ranges. Specifically, we evaluated how crude protein, digestible energy, and relative abundance changed throughout the growing season and whether deer altered their diet to reflect species-specific changes in plant phenology. In support of the Forage Maturation Hypothesis, forage quality declined as large-scale patterns of phenology progressed away from a remotely sensed metric of peak green-up for most plant species on the summer ranges of deer that migrated short (&lt;50 km), medium (50–130 km), and long distances (&gt;130 km). Declining rates in forage quality among plant species were heterogeneous, providing deer with the phenological diversity required to microsurf. Deer changed their diet throughout the growing season and prioritized the consumption of some plants, including <i>Rosa woodsii</i> and <i>Purshia tridentata</i>, as the rank of forage quality increased (<i>p</i> &lt; 0.01). In light of the complexities common to studies on foraging behavior, our findings suggest that deer may have some potential to microsurf on summer range when heterogeneity in resource phenology is prevalent. Moreover, our findings validate the accuracy of remote sensing in quantifying peak forage quality for plants within sagebrush shrublands and montane habitats.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"106 4","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143857033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plant-chemical defenses mediate biotic interactions between plants and their natural enemies and provide a highly dimensional trait space in which chemically mediated niches may facilitate plant species coexistence. However, the role of chemically mediated biotic interactions in shaping plant communities remains largely untested across large-scale ecological gradients. Here, we used ecological metabolomics to quantify the chemical dissimilarity of foliar metabolomes among 473 tree species in 16 tropical tree communities along an elevational gradient in the Bolivian Andes. We predicted that tree species diversity would be higher in communities and climates where co-occurring tree species are more chemically dissimilar and exhibit faster evolution of secondary metabolites (lower chemical phylogenetic signal). Further, we predicted that these relationships should be especially pronounced for secondary metabolites known to include antiherbivore and antimicrobial defenses relative to primary metabolites. Using structural equation models, we quantified the direct effects of rarefied median chemical dissimilarity and chemical phylogenetic signal on tree species diversity, as well as the indirect effects of climate. We found that chemical dissimilarity among tree species with respect to all metabolites and secondary metabolites had positive direct effects on tree species diversity, and that climate (higher temperature and precipitation, and lower temperature seasonality) had positive indirect effects on species diversity by increasing chemical dissimilarity. In contrast, chemical dissimilarity of primary metabolites was unrelated to species diversity and climate. Chemical phylogenetic signal of all metabolite classes had negative direct effects on tree species diversity, indicating faster evolution of metabolites in more diverse communities. Climate had a direct effect on species diversity but did not indirectly affect diversity through chemical phylogenetic signal. Our results support the hypothesis that chemically mediated biotic interactions shape elevational diversity gradients by imposing stronger selection for chemical divergence in more diverse communities and maintaining higher chemical dissimilarity among species in warmer, wetter, and more stable climates.

Theory suggests such conspecific aggregation can delay competitive exclusion by sparing weak competitors. However, the extent to which spatial aggregation increases species performance and which species are likely to benefit from it remain largely unknown. In this study, we asked (1) whether spatial aggregation enhances plant performance and (2) whether the effects are biologically predictable. For the second question, we focused on “the competition-relatedness hypothesis” and the “competitive asymmetry hypothesis,” which relate the effect of spatial arrangement to niche and competitive ability differences between species, respectively. We performed phylogenetic meta-analyses to investigate whether phylogenetic and ecological differences among competitors explain the effect of spatial arrangement. We found idiosyncratic responses of plant species to spatial aggregation. While some species performed better when conspecific individuals were aggregated, others did so when conspecifics and heterospecifics were randomly distributed. The non-negligible number of species benefiting more from intraspecific aggregation indicates that intraspecific competition is sometimes weaker than interspecific competition. Further, the result contrasts with the assumption of the competition-relatedness hypothesis, which postulates the strongest competition among conspecifics, suggesting that this hypothesis does not hold for at least these species. Although phylogeny did not predict the effect of spatial arrangement, interspecific plant height differences did: Species performed better in an aggregation treatment when they were smaller than competitors. Collectively, our results lend more support for the competitive asymmetry hypothesis that interspecific differences in competitive ability underpin the effect of spatial arrangement on plant performance.
