Snow depth observations, Northern Sweden The effect of reindeer on snow depth has been measured in two study sites. The first is a large enclosure used for winter feeding of Norwegian reindeer (Gielas reindeer herding districts) in Northernmost Sweden, close to the Vassijaure railway station (68({}^{circ }2{5}^{{prime} }46.{2}^{{primeprime} })N,(1{8}^{circ }2{0}^{{prime} }47.{3}^{{primeprime} })E). Inside the enclosure, 700 […] More

This paper introduced homophily based friendship choice into a model in which individuals replace missing kin with non-kin friends. The results show that similarity-based friendship choice increases the clustering coefficient, and thus it is an adaptive response to decreasing interconnectedness within the individual’s immediate social network. This is of import as although the clustering coefficient […] More

Conservation, restoration, and rewilding of complex systems are global grand challenges. Important conceptual developments in these fields include habitat occupancy models1, species distribution models2, and home-range analyses with occurrence data3. We need to know how plants and animals use and occupy space. Nonetheless, many animal populations including endangered species likely have limited access to potential […] More

County-level data in California We use annual crop yields, harvested area, production and economic value data for 58 counties in California for the years 1980–2015 from the California County Agricultural Commissioners’ reports21.
