Disproportionate mortality of males, presumably an important cause of the change in sex ratio of the snow leopard
population in Tost, is reported in
several carnivores as resulting from human - induced factors such as poaching and retaliatory killing, including Amur
tigers in southeast Russia [32], leopards in South Africa [34], and cougars in the Pacific Northwest [33], although there are exceptions (e.g.
tiger population in Panna, Central India, that had turned male - biased prior to extinction due to poaching; [36], [37]-RRB-.
Several projects were successfully completed or reached significant milestones, including: First time in 100 years that the global
population of wild
tigers has increased, with 60 % growth where WWF - Canada works on
tiger conservation in Nepal; first ever certified sustainable cod fishery in Canada; first ever national measure of the health of our freshwater ecosystems reaching 75 % completion; and, end of oil exploration interests near Arctic's Lancaster Sound region
