摘要：

In this study I compared live-trapping and snap-trapping as means to assess abundance and population trends of deer mice Peromyscus maniculatus (Wagner, 1845) in the southern Yukon. I also investigated the presence of "trap-shy" individuals which may invalidate the central assumption of mark-recapture and enumeration methods. Live-trapping was very efficient for this population of deer mice. Snap-trapping the two previously live-trapped populations showed that 11% and 12% of the individuals were not tagged. These untagged individuals could be either "trap-shy" or new recruits. Both snap-trapping and live-trapping provided similar estimates of population size and trend. However, the sex and age structure revealed by each method were very different. An important incidental result was that both minimum number alive and Jolly-Seber estimates were very similar.
