Temperature increase altered Daphnia community structure in artificially heated lakes: a potential scenario for a warmer future

Abstract Under conditions of global warming, organisms are expected to track their thermal preferences, invading new habitats at higher latitudes and altitudes and altering the structure of local communities. To fend off potential invaders, indigenous communities/populations will have to rapidly ada...
