Aim To test the hypothesis of bioclimatic niche conservation in an alien species. Location Northern Hemisphere temperate and boreal zones. Taxon Tree squirrels of the genera Sciurus and Tamiasciurus , especially S. carolinensis (Eastern Grey Squirrel). Methods Climatic response surface species distribution models (SDMs) are fitted using a limited set of biologically‐relevant bioclimatic variables. Two models are fitted for Sci...

Aim To quantify the intra‐community variability of leaf‐out (ICVLo) among dominant trees in temperate deciduous forests, assess its links with specific and phylogenetic diversity, identify its environmental drivers and deduce its ecological consequences with regard to radiation received and exposure to late frost. Location Eastern North America (ENA) and Europe (EUR). Time Period 2009–2022. Major Taxa Studied Temperate deciduo...

Aim The geographical distribution of bacteria is an important, but poorly understood, topic in microbial ecology. A major question is how broadly distributed generalist taxa, and limitedly distributed specialist taxa, vary across a latitudinal gradient in freshwater ecosystems. We predict that: (a) generalists and specialists exhibit latitudinal diversity gradient with different patterns; (b) their community assemblies are mai...

Aim How plants can disperse in response to global change is a critical question, yet major knowledge gaps persist about long‐distance dispersal (LDD) mechanisms. We studied the potential a migratory waterfowl has for LDD of flowering plants via gut passage of seeds (endozoochory), comparing spring and autumn migration. Location United Kingdom and Iceland. Taxon Pink‐footed Goose ( Anser brachyrhynchus , Baillon) and Angiosperm...
