Melissa J. Reynolds-Hogland, Auteur ; Lara B. Pacifici, Auteur ; Michael S. Mitchell, AuteurIdentifying the resources that limit growth of animal populations is essential for effective conservation; however, resource limitation is difficult to quantify. Recent advances in geographical information systems (GIS) and resource modelling ca[...]
