We analysed a dataset describing 125 earthworm communities sampled in 10 localities in French Guiana. DNA barcodes were used to delimit operational taxonomic units (OTUs) that we considered as species surrogates to avoid the taxonomic deficit and calculate community-scale species richness and pair-wise Sørensen beta-diversity. We used log-ratio and generalised linear models to highlight the effects of biotic interactions and environment as drivers of alpha diversity, and generalised dissimilarity models to figure out the relative contribution of space and environment to beta-diversity at different spatial extents. Community-scale alpha diversity was mainly explained by habitat filtering (soil texture) and interspecific competition that limit the number of locally co-existing species. Beta diversity between pairs of communities was mainly explained by distance when comparing communities in similar habitats, by topography and available soil phosphorus when comparing communities in different habitats, and by distance, elevation and climate when comparing all possible pairs of communities. While community composition is determined locally by neutral processes and environmental filtering, biogeographic processes linked to dispersal limitation and adaptation to local environment are the most influential on a regional scale. This highlights the complex interplay of dispersal limitation, biotic interactions and environmental filtering during the process of community assembly.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 9","pages":"151"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144963393","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}

Flowering patterns of alpine plants were formed by the combination of early-flowering fellfield and late-flowering snowbed communities, where snowbed flowers were important resources for worker bees. The flowering phenology of the fellfield communities was correlated with early season air temperature, whereas that of the snowbed communities was clearly predicted by snowmelt time. It was predicted that 1 °C warming with 10 days earlier snowmelt would advance the peak flowering time of the fellfield and snowbed communities by 3.6 and 9.5 days, respectively, resulting in a 9.2 day shorter flowering period. In contrast, the peak time of worker abundance was consistent between years, independent of temperature and snowmelt time. As a result, the time lag between the peak flowering of snowbed plants and the peak abundance of worker bees, i.e., the phenological mismatch, increased with earlier snowmelt. Mid-summer temperature was negatively correlated with worker abundance for three Bombus species, and the effect of phenological mismatch varied between Bombus species. The abundance of B. hypocrita decreased with increasing phenological mismatch in the previous year, the abundance of B. beaticola and B. yezoensis increased, and B. hypnorum showed no clear response. Therefore, changes in the phenology of alpine plants due to global warming affect pollinators in highly species-specific ways.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 9","pages":"150"},"PeriodicalIF":2.3,"publicationDate":"2025-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12374912/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144963356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One hypothesis states that these weak temporal NPP-PPT associations arise from the lagged effects of previous-year conditions, denoted as \"legacy effects,\" which may amplify or constrain NPP in subsequent years. Although evidence suggests the existence of legacy effects in many ecosystem types, their generality in drylands remains unclear. We used long-term (35-year) remotely sensed estimates of NPP, climate, and a vegetation structure across the western United States to quantify the sign, magnitude, and drivers of legacy effects, defined as the lagged effects of previous-year weather and NPP anomalies on current-year NPP. Legacy effects exert a widespread effect on interannual variability in NPP across drylands spanning annual and perennial grasslands to hot and cold deserts. Previous-year NPP anomalies were the strongest predictor of current-year NPP anomalies, both across the entire time series and during specific extreme-to-average year transitions. The association between previous- and current-year NPP anomalies was consistently positive, indicating that a productive previous year will tend to result in a productive current year, and vice versa, even after accounting for the effect of current-year PPT. The strength of legacy effects increased slightly with increasing mean annual PPT and decreased slightly with an increase in the average fraction of herbaceous NPP. We conclude that legacy effects consistently effect current-year NPP in drylands and that consideration of these effects can improve predictions of temporal variation in dryland NPP.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 9","pages":"149"},"PeriodicalIF":2.3,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12373685/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144963529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Insects are a ubiquitous group that exhibits a variety of functional traits, and studying these traits could prove useful for understanding insect community assembly. We use insect trait measurements, community sampling along a disturbance gradient, and a cafeteria-style feeding assay to elucidate the mechanisms that govern insect herbivore community assembly processes. Using a trait principal component analysis, we first identified life history trade-offs between herbivore feeding and nutrition based on 3 traits measured on 14 grasshopper species collected across 30 pine savanna field sites. In the field, we tested hypotheses regarding how competition or environmental filtering might structure communities by examining dispersion patterns of functional traits. We found that grasshopper incisor strength and C:N ratio were consistently under-dispersed, patterns that indicate trait-clustering resulting from environmental filtering. Using mesocosms, we tested the hypothesis that grasshopper species should exhibit differentiation in their feeding niches based on the traits of the plants they consume and that feeding traits should correlate with traits of consumed plants. We demonstrated that grasshopper species strongly differentiated their feeding niche based on the traits of plants incorporated into their diets. We also found linkages between herbivore incisor strength and plant leaf dry matter content, and between grasshopper C:N ratio or body size and plant C:N ratio. This study revealed likely mechanisms that govern the interactions between insect herbivores, the plants they feed on, and how they partition resources to coexist.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 9","pages":"147"},"PeriodicalIF":2.3,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12370786/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144963378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little is known about the abundance, diversity, distribution, and ecological roles of micro-invertebrates above the forest floor, particularly within tree-related microhabitats (TreMs). In this study, we sampled 18 distinct types of TreMs in the UNESCO World Heritage old-growth beech forest of La Massane, located in the southeastern Pyrenees. We extracted and counted various groups of micro-invertebrates (nematodes, tardigrades, rotifers, and mites) associated with these TreMs, and identified nematodes to the species level. Additionally, we measured the stable isotopic signatures of carbon and nitrogen in various resources and invertebrate groups to reveal the structure of TreM-associated food webs in unprecedented detail. TreMs emerged as hotspots of both abundance (averaging 195 individuals per gram of dry TreM substrate) and diversity (98 nematode morphospecies across 20 families). We found significant differences among TreM types in terms of community composition and food web structure, revealing distinct species assemblages and trophic pathways. These differences could be linked to factors such as the stage of wood decomposition, occupation by larger animals (e.g., insects, birds), and the position of TreMs within trees. Our findings suggest that micro-invertebrates serve as valuable ecological indicators, adding a new layer of biodiversity and functional understanding to TreM typology. This, in turn, supports more comprehensive strategies for nature conservation and forest management.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 9","pages":"148"},"PeriodicalIF":2.3,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12370837/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144963447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, there is considerable evidence that ecosystem sensitivity to drought, quantified by reductions in aboveground net primary production (ANPP), is negatively related to mean annual precipitation (MAP). Thus, arid ecosystems are more likely than mesic systems to experience dramatic reductions in productivity during drought. However, evidence for this pattern is primarily from studies that span multiple biomes making it difficult to discern if abiotic (MAP) or biotic factors (differences in plant communities) underlie this relationship. To disentangle these, we assessed patterns of drought sensitivity within a single biome, the semiarid shortgrass steppe of the western U.S., where the dominant vegetation varies minimally compared to cross-biomes studies. We used 23 years of satellite derived ANPP proxies, the Normalized Difference Vegetation Index (NDVI) and the Enhanced Vegetation Index (EVI, 157,929 pixels, 1 km2 resolution) with gridded precipitation data to assess relationships between drought sensitivity and MAP within this biome. Consistent with previous multi-biome studies, we found a negative, although relatively weaker, relationship between MAP (250-625 mm) and drought sensitivity within the shortgrass steppe. We conclude that while differences in vegetation types almost certainly contribute to patterns of drought sensitivity, the long-term precipitation history of an ecosystem (e.g. MAP) may also play a role in determining differences in drought sensitivity within ecosystems.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 9","pages":"146"},"PeriodicalIF":2.3,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12367911/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144963396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Substrate-borne vibrations provide a window that addresses this shortcoming. Under natural conditions, we implemented a passive monitoring system that measures vibrations produced by two miniaturized Puerto Rican geckos: Sphaerodactylus grandisquamis in the mesic karst forest and Sphaerodactylus townsendi in the coastal dry forest. The dichotomy between habitats allowed us to test the hypothesis that microclimate conditions drive divergence in thermoregulatory behavior. For each species in its native habitat, thirty individuals were monitored inside a field enclosure, excluding other vibration sources. We measured vibrations at two strata depths (i.e., surface and bottom) to characterize behavioral responses to diel cycle, microclimate, and predatory bird calls. Vibrational data revealed contrasting activity patterns across strata. Mesic S. grandisquamis showed continuous daytime activity at all strata levels, regardless of microclimate. Dry forest S. townsendi featured a biphasic activity pattern, peaking midday and at dusk, and increased activity in deeper litter strata during hot and dry conditions (i.e., midday). Analysis at fine temporal scales for S. grandisquamis revealed a reduction in surface activity after the onset of bird calls from three species that pose a predation risk. Our results demonstrate interspecific differences in thermoregulatory behavior that likely increase the fitness of each species in their respective habitats. Furthermore, vibrational monitoring strongly suggests Sphaerodactylus exploit their niche in a three-dimensional manner, mirroring habitat use patterns of arboreal fauna and highlighting the importance of incorporating multiple strata levels when studying leaf litter microhabitats.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 9","pages":"144"},"PeriodicalIF":2.3,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144874405","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}

In field tent experiments, we allowed caterpillars of P. brassicae to develop from leaf-feeding early instars to flower-feeding late instars and assessed pollinator response to undamaged and damaged plants during 10-min observations. We recorded behaviours with potential effect on outcrossing: (first) choice and overall plant preference, plant visit duration, number and duration of flower visits per plant, and distance travelled between plant visits. Bumblebees visited more plants and flowers, but spent less time per flower than butterflies did. Bumblebees often travelled to neighboring plants, whereas butterflies often flew longer distances to reach a next plant. Herbivory by large florivorous caterpillars altered butterfly plant choice-mostly towards plants with caterpillars, but not their behaviour on the plant. Bumblebees did not alter their choices, but changed their behaviour on the plant: they visited more flowers on plants with herbivory. However, herbivory by small leaf-feeding caterpillars did not affect the behaviour of either pollinator. Our results show that pollinator community members respond differently to herbivory and that this response changes over time, potentially affecting plant mating patterns.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 9","pages":"143"},"PeriodicalIF":2.3,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12354498/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144855941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a systematic literature review covering individual, population, and community-level assessments to determine the impacts posed to animal biodiversity by electrical infrastructure and the measures to reduce impacts. Our results show that the literature around electrical infrastructure and animal biodiversity has grown exponentially since the start of the millennium and is biased towards birds and mammals in economically developed countries. We found the majority of reported impacts were negative, occurring primarily through barrier effects (collision) and use of linear features as a resource (electrocution), causing significant population impacts in select species. However, we also found that electrical infrastructure provided positive effects (increased habitat provisioning) to certain taxonomic groups (e.g. corvids, storks), which suggests the potential to encourage conservation efforts using appropriate mitigation on electrical infrastructure. We found the majority of current literature detailed mitigation measures focused on reducing collisions through line (51%) and tower alterations (30%), but often omitted the impacts of EMF, noise, and UV, indicating significant knowledge gaps. On a wider scale, we found that mortality from electrical infrastructure ranked lower than building collisions and predation from feral cats, but remained higher than other anthropogenic energy sources, indicating the potential to cause significant impacts to large-bodied bird species if not addressed.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 9","pages":"142"},"PeriodicalIF":2.3,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12350552/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144835844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
