Abstract Aims Climate change is known to drive both the reshuffling of whole assemblages and range shifts individual species. Less about how local colonizations extinctions species contribute changes at community level. Our aim was estimate contribution a in composition attributed climate relate these species‐specific contributions species’ commonness, climatic niche characteristics life history traits most likely influence sensitivity change.

Abstract Land use intensification favours particular trophic groups which can induce architectural changes in food webs. These impact ecosystem functions, services, stability and resilience. However, the imprint of land management intensity on food‐web architecture has rarely been characterized across large spatial extent various uses. We investigated influence six facets architecture, namely apex basal species proportions, connectance, omnivory, chain lengths compartmentalization, for...
Abstract Aim Protected areas ( PA s) are the mainstay of our conservation strategies. While they may succeed in locally preventing species and habitat degradation due to human activities, their ability mitigate impacts climate change on biodiversity is still debated. We assessed whether community responses were related s by testing three main predictions: (1) thermal adjustment composition temperature changes should be positively proportion s, (2) that benefit most from less impacted change,...
Abstract Biotic interactions are widely recognised as the backbone of ecological communities, but how best to study them is a subject intense debate, especially at macro‐ecological scales. While some researchers claim that biotic need be observed directly, others use proxies and statistical approaches infer them. Despite this ambiguity, studying predicting influence on biogeographic patterns thriving area research with crucial implications for conservation. Three distinct currently being...
The local spatial congruence between climate changes and community has rarely been studied over large areas. We proposed one of the first comprehensive frameworks tracking in composition related to changes. First, we investigated whether how 12 years bird communities were variations. Then, tested consequences this climate-induced adjustment on Grinnellian (habitat-related) Eltonian (function-related) homogenization. A standardized protocol monitoring temporal trends birds France from 2001...
Abstract The spatial tracking of climatic shifts is frequently reported as a biodiversity response to change. However, species’ range are often idiosyncratic and inconsistent with shift predictions. At the community scale, this discrepancy can be measured by comparing in relative composition cold‐ vs. warm‐adapted species local assemblage [the temperature index ( CTI )] isotherms. While distribution climate change velocity promising approach downscaling pressure responses, has only been...
Abstract Conserving functionally diverse bird communities in European farmland is becoming critical, with no exception for regions of wine production. Management intensification combined the loss semi‐natural habitats wine‐growing landscapes has led to a long‐term decline not only birds conservation concern but also once common insectivores and seed eaters. These declines are expected threaten key ecological services provided by vineyard birds, such as pest or weed control, their cultural...
Abstract Aim We disentangle three facets of species commonness (local abundance, geographical range size, degree habitat generalization) to identify how segregate along these axes and each determines the relative functional originality (i.e. mean trait distance a with others). At community level we test whether changes in abundances different levels contribute spatial temporal dynamics assemblages local trend homogenization. Location F rance.

The Anthropocene is characterized by a rapid pace of environmental change and causing multitude biotic responses, including those that affect the spatial distribution species. Lagged responses are frequent species distributions assemblages consequently pushed into disequilibrium state. How characteristics change-for example, gradual 'press' disturbances such as rising temperatures due to climate versus infrequent 'pulse' extreme events-affect magnitude relaxation times biota has been...
Robust predictions of ecosystem responses to climate change are challenging. To achieve such predictions, ecology has extensively relied on the assumption that community states and dynamics at equilibrium with climate. However, empirical evidence from Quaternary contemporary data suggest species communities rarely follow change. This discrepancy between conceptual foundation many predictive models observed casts doubts our ability successfully predict future states. Here we used response...
Beyond the local abundance of species, their functional trait distinctiveness is now recognized as a key driver community dynamics and ecosystem functioning. Yet, since species always relative to given pool, distinct at regional scale might not necessarily be or scale, reciprocally. To assess importance (i.e. definition pool) when quantifying how it distort ecological conclusions derived from it, we quantified 1350 plant regional, scales over ca 88 000 grassland plots in France. We measured...
Abstract Aim The functional trait composition of plant communities is thought to be determined largely by climate, but relationships between contemporary distributions and climate are often weak. Spatial mismatches climatic conditions commonly arise from disequilibrium responses past environmental changes. We aimed investigate whether current trait–climate likely emerge during Holocene warming. Location North America. Time period 14–0 ka. Major taxa studied Terrestrial plants. Methods joined...
Global changes alter the dynamics of biodiversity, and are forecasted to continue or worsen in decades come. Modelling approaches used anticipate these impacts mainly based on equivalence between spatial temporal response environmental forcings, generally called space‐for‐time substitution. However, several processes known generate deviations responses, potentially undermining prediction We here high‐resolution data from french breeding bird survey quantify map deviation patterns abundances...
Despite evidence of a positive effect functional diversity on ecosystem productivity, the importance functionally distinct species (i.e. that display an original combination traits) is poorly understood. To investigate how affect we used forest-gap model to simulate realistic temperate forest successions along environmental gradient and measured productivity at end successional trajectories. We performed 10 560 simulations with different sets numbers species, bearing either or indistinct...
Abstract Little is known about whether changes in lake ecosystem structure over the past 150 years are unprecedented when considering longer timescales. Similarly, research linking environmental stressors to ecological resilience has traditionally focused on a few sentinel sites, hindering study of spatially synchronous across large areas. Here, we studied signatures paleolimnological by tracking change diatom community composition last 2000 four Ecuadorian Andean lakes with contrasting...
Abstract Aim Understanding how combinations of ecological traits at the community‐level vary with environmental conditions is crucial to anticipate and respond biodiversity crisis. While this topic popular, most attempts analyse predict multiple in space time ignore inherent correlations between these traits. In doing so, predicted unobserved environments are likely be flawed (i.e. unrealistic trait combinations). Here, we propose a framework that addresses methodological question functional...

Whether how much associations between are also changing less documented.
