Data for "Decreasing snow cover alters functional composition and diversity of Arctic tundra"

This page links to the data and code associated with the publication Niittynen et al. (2020) "Decreasing snow cover alters functional composition and diversity of Arctic tundra" published in PNAS ( https://doi.org/10.1073/pnas.2001254117 ). The species data contain cover values of 200 vascular plant species recorded in 1325 study sites in Rastigaisa area in Northern Norway. The trait data includes species level median trait values for the 200 species calculated from records extracted from public databases for seven plant functional traits and community weighted means of these traits calculated for all the 1325 study sites. The environmental data contain six spatially continuous predictors used in the species level models. The data and analyses are described in the linked publication.
