Biodiversity of intertidal food webs in response to warming across latitudes
International audience Global warming threatens community stability and biodiversity around the globe. Knowledge on the underlying mechanisms depends heavily on generic food-web models that do not account for changes in network structure along latitudes and temperature gradients. Using 124 marine ro...

International audience Global warming threatens community stability and biodiversity around the globe. Knowledge on the underlying mechanisms depends heavily on generic food-web models that do not account for changes in network structure along latitudes and temperature gradients.

We used dynamic modelling to test if communities from warmer regions were more sensitive to warming and found a general humped-shaped relationship between simulated biodiversity and temperature (gradient from 0-50°C).
