Data for: Rapid shifts in Arctic tundra species’ distributions and inter-specific range overlap under future climate change

Aim: The Arctic is one of the planet’s most rapidly warming regions, with trends expected to intensify in the future. Projections of shifts in species distributional ranges under future climate change are thus far lacking for most vertebrate species using the Arctic tundra. Our aim was to assess possible climate-induced changes in distributional ranges and inter-specific overlap of an Arctic species assemblage within the world’s largest land-based protected area.

Location: During 1979-2013 location data of eight Arctic birds and mammals: Arctic fox (Vulpes lagopus), Arctic hare (Lepus arcticus), Arctic wolf (Canis lupus arctos), muskox (Ovibos moschatus), polar bear (Ursus maritimus), rock ptarmigan (Lagopus muta), snow bunting (Plectrophenax nivalis), and snowy owl (Bubo scandiacus) were collected in the Northeast Greenland National Park.

Methods: The maximum entropy (MaxEnt) algorithm and Schoener’s D niche overlap index were used to assess shifts and changes in overlap of spec..., Location data of 8 Arctic vertebrate species were collected in the Northeast Greenland National Park during reconnaissance trips by the Sirius Dog Sled Patrol between 1979-2013. Location data were analysed using the maximum entropy (MaxEnt) algorithm to assess shifts and changes in overlap of species-specific distributions under recent (1979-2013) and future (2061-2080; representative concentration pathways [RCPs] 2.6, 4.5 and 8.5) bioclimatic conditions.
