Climate change reshuffles northern species within their niches

L. H. Antão, B. Weigel, et al.

Climate change is causing significant shifts in species' positions within their climatic niches, particularly at higher latitudes. This research, conducted by a team from the University of Helsinki and other institutions, reveals how biodiversity responses are complicating ecosystem integrity over four decades in Finland.

Abstract
Climate change is a pervasive threat to biodiversity. While range shifts are a known consequence of climate warming contributing to regional community change, less is known about how species' positions shift within their climatic niches. This study analyzed four decades of data for 1,478 species across a 1,200 km latitudinal gradient in Finland. Results showed substantial shifts in species' relative niche positions over time, with a greater proportion of species responding to climatic change at higher latitudes. These diverging climate imprints restructure the biome, highlighting the complexity of biodiversity responses and raising concerns about ecosystem integrity.
