Mountain ecology under climate change Climate warming causes shifts in the distributions of organisms and different may move at rates, resulting changes composition functioning ecological communities. These effects are rarely considered forecasts about on biodiversity. Using experimental translocations, Descombes et al. investigated how differential upslope migration alpine plants their insect herbivores affects community interactions. Lowland modify three-dimensional vegetation structure higher altitudes, this modified favors coexistence plant species, especially by favoring small-stature species. Reorganized trophic interactions will play an important role driving future change. Science , issue p. 1469
