Increasing importance of climate change and other threats to at-risk species in Canada
In a previous analysis, six major threats to at-risk species in Canada were quantified: habitat loss, introduced species, over-exploitation, pollution, native species interactions, and natural causes (O. Venter et al. 2006. Bioscience, 56(11): 903–910). Because of rapid environmental change in Canad...
