Marine sublittoral benthos fails to track temperature in response to climate change in a biogeographical transition zone
Abstract Species ranges are shifting globally to track temperature changes in response to climate warming, with substantial variability among taxa. In the English Channel, a biogeographical transition zone between the cold temperate and warm temperate provinces of the North-East Atlantic, distributi...

These results suggest that ongoing climate change could lead to a decrease in benthic biodiversity at range limits, especially where connection routes are lacking for new migrants.

Abstract Species ranges are shifting globally to track temperature changes in response to climate warming, with substantial variability among taxa.
