Natura 2000 is a European network of sites dedicated to the conservation of vulnerable habitats. The definitions of Natura 2000 habitats are mainly based on plant communities. We investigated if the increase of the dominance of warm-adapted species observed in plant communities, described as thermophilization, had already led to measurable changes...

High rates of species extinction have been predicted for the next century as a consequence of climate change. Although species range shifts have been widely reported, evidence of changes in species frequency linked to recent climate change is scarce. Moreover, studies have mainly focused on mountainous ecosystems and species. There is thus a clear...
Article
Poleward and upward species range shifts are the most commonly anticipated and studied consequences of climate warming. However, these global responses to climate change obscure more complex distribution change patterns. We hypothesize that the spatial arrangement of mountain ranges and, consequently, climatic gradients in Europe, will result in ra...

... L'augmentation des températures est toutefois plus rapide que leur capacité de déplacement, en particulier pour la flore (Martin et al. 2019). Le réchauffement climatique induit également des changement à l'échelle des habitats forestiers, avec des impacts différenciés sur les habitats des régions en altitude (modification vers des habitats plus chauds) et les plaines (où les communautés végétales semblent inertes et développent une « dette climatique ») (Maciejewski et al. 2020). Par ailleurs, d'autres paramètres que la température déterminent la répartition des espèces, par exemple des obstacles limitant la possibilité de colonisation de nouveaux espaces plus au nord ou en altitude. ...
... Conditions generally become more suitable in the poleward direction whereas they become unsuitable in the equatorial direction . Similar changes are seen over elevational gradients (Kuhn and Gegout 2019). However, rearrangement in space requires the presence of suitable habitat, connectivity, species mobility, and successful population establishment (Schippers et al. 2011). ...
... Marine currents that flow predominately in one direction along a coastline (when propagules are released) will limit the directionality of range shifts in a similar way that animal movements limit range shifts of certain plants (Box 2) [56,57]. The east-west orientation of physical features, such as mountain ranges or coastlines, will also impede poleward shifts or even shift species toward lower latitudes at higher elevations or deeper depths [58,59]. Finally, habitat discontinuities are important across realms, including the absence of rocky habitat amid long stretches of sandy, marine habitat or the absence of upland forest at lower elevations. ...
