Variable Description Spatial Resolution Temporal Resolution Reference
Human influence Influence index created by combining scores across 9 global data layers covering human population pressure (population density), human land use and infrastructure (built-up areas, nighttime lights, land use/land cover), and human access (roads, coastlines, navigable rivers). 1km 1995-2004 Wildlife Conservation Society & Center for International Earth Science Information Network (2005)
Snow cover National Centers for Environmental Prediction North American Regional Reanalysis is a high-resolution reanalysis of the North American region including assimilated precipitation. 5km Annual averages taken during winter (October-March) between 1979-2003 Mesinger et al., (2006)
Snow depth
Mean temperature of the warmest quarter Part of 19 bioclimatic variables estimated monthly and averaged annually for North America. 10km Annual averages estimated between 1981-2010 McKenny et al., (2011)
Mean temperature of the coldest quarter
Precipitation of the wettest quarter
Precipitation of the driest quarter
Land cover Global composites and land cover maps allocate land cover into 22 categories, using input observations from the 300m MERIS sensor on board the ENVISAT satellite mission. This data was reclassified into a binary matrix to estimate the proportion of suitable (1) and unsuitable (0) lynx habitat. 300m January-December 2009 European Space Agency & Université Catholique de Louvain (2010)
