Future ocean climate homogenizes communities across habitats through diversity loss and rise of generalist species
Predictions of the effects of global change on ecological communities are largely based on single habitats. Yet in nature, habitats are interconnected through the exchange of energy and organisms, and the responses of local communities may not extend to emerging community networks (i.e., metacommuni...
