Abstract
This repository contains the dataset analyzed in 'Winter conditions structure extratropical patterns of species richness of amphibians, birds, and mammals globally' - published in the journal Global Ecology and Biogeography - and the R code used to generate the correlations, generalized additive models, and related figures presented in the manuscript. Column descriptions for the data can be found in the associated README.txt file. Please refer to the manuscript for further detail on the variables and how they were derived.
The Winter Indices (WIs) were derived using satellite remote sensing data from optical (MODIS, snow cover) and microwave (MEaSUREs freeze/thaw, frozen ground) sensors. The species richness maps were derived using IUCN range maps for individual species of amphibians, birds, and mammals (data requests can be made here: https://www.iucnredlist.org/resources/spatial-data-download). Climatic varibales were derived from WorldClim v2.0 data, elevation from USGS GMTED2010 data, and primary productivity from the cumulative dynamic habitat index available here: http://silvis.forest.wisc.edu/maps-data/.
