Arctic greening and bird nest predation risk across tundra ecotones

Nature Climate Change, Published online: 01 July 2019; doi:10.1038/s41558-019-0514-9

Bird numbers are declining globally, with sharp decreases in alpine and Arctic regions. Increases in primary productivity in the Arctic (known as greening) are linked to increased nest predation, highlighting how changing climate conditions can affect food web dynamics.
