Estimating Densities of Peromyscus leucopus Using Live-Trap and Nestbox Censuses

摘要: We determined if various trap and nestbox census methods used during a 22-year monthly study yielded consistent density estimates of the white-footed mouse ( Peromyscus leucopus ) in an Ohio woodlot. Because were concurrently for only 32 months study, we also compared that had been sequentially by first removing seasonality using density-dependent parameters. Nestbox lower than summer higher winter, three variations over 22 years did not result different estimates. Twenty-five percent individuals caught nestboxes never traps, increased densities 7% increasing nest-sites 15 they remained ‘minimum number alive’ estimator could overestimate population isolated woodlot, censuses underestimated accurately estimated late autumn winter.
