Along with worldwide urbanization, upheavals in habitat and temperature are major threats for biodiversity. However, due to their interdependence, relative roles as drivers of animal community composition remain entangled. Here, we investigated how taxonomic functional compositions arthropod communities were related uncorrelated gradients, compared landscape (i.e., Urban Heat Island (UHI)) local variables vegetation height cover, near-ground temperature). We sampled 20,499 spiders (137...
Spiders are a highly diversified group of arthropods and play an important role in terrestrial ecosystems as ubiquitous predators, which makes them suitable to test variety eco-evolutionary hypotheses. For this purpose, knowledge diverse range species traits is required. Until now, data on spider have been scattered across thousands publications produced for over two centuries written languages. To facilitate access such data, we developed online database archiving accessing at global scale....
Hedgerows are key wildlife habitats in agricultural landscapes, with presumably high multifunctionality – that is the capacity to provide multiple ecological, agronomic or cultural functions. However, knowledge gaps remain regarding drivers of hedgerow and potential synergies trade-offs between In particular, it unknown which landscapes hedgerows best support a range taxa associated We assessed effects features, adjoining farming systems, landscape context, their interactions on based four...
An important question in evolutionary ecology is to understand the drivers of phenotypic variation contrasting environments. Disentangling plasticity from responses such contexts provides a better understanding how organisms adapt changing climates. Many aspects seasonal insect populations are essential for their persistence temperate environments, including capacity overwinter. Phenotypic should result locally adapted diapause levels experienced environmental conditions. Using an outdoor...
Mechanisms underlying biological diversities at different scales have received significant attention over the last decades. The hypothesis of whether local abiotic factors, driving functional and phylogenetic diversities, can differ among taxa arthropods remains under-investigated. In this study, we compared correlations drivers diversity (FD) (PD) between spiders carabids, two dominant ground-dwelling in salt marshes. Both exhibited high correlation FD PD; was even higher probably owing to...
Abstract While mechanisms underlying biological diversities at different scales received huge attention over the last decades, whether local abiotic factors driving functional and phylogenetic can differ among ecologically phylogenetically closely related taxa remains under-investigated. In this study, we compared correlations drivers of (FD) (PD) between two dominant ground-dwelling arthropods in salt marshes, spiders carabids. Pitfall trapping sampling sites N-W France resulted collection...
<title>Abstract</title> In the Seine estuary in northern France, many artificial structures limit effect of tide on associated alluvial zones. Consequently, this affects natural environmental filtering mechanisms linked to tidal regimes and water salinity, which directly influences structure organism assemblies adjacent ecosystems. Here, we propose study influence these filters' modifications spiders plants, two compartments recognized as complementary terms bioindication. However,...
