Climate change vulnerability higher in arctic than alpine bumblebees
Arctic and alpine species are expected to be particularly vulnerable to climate change as they inhabit areas of extreme climates. To understand how such species may respond, we compared two groups of bumblebees that specialise in arctic (Alpinobombus) and alpine (Mendacibombus) biomes. These bumbleb...

Arctic and alpine species are expected to be particularly vulnerable to climate change as they inhabit areas of extreme climates.

Using an ensemble of species distribution models for eighteen bumblebee species (ten Mendacibombus; eight Alpinobombus), we estimated their current distributions using selected climate variables.
