Decomposition and Arthropod Succession in Whitehorse, Yukon Territory, Canada
Abstract Forensic arthropod succession patterns are known to vary between regions. However, the northern habitats of the globe have been largely left unstudied. Three pig carcasses were studied outdoors in W hitehorse, Y ukon T erritory. Adult and immature insects were collected for identification a...
