Linking behavior, life history and food supply with the population dynamics of white-footed mice (Peromyscus leucopus).

In this paper we review and integrate key aspects of behavioral and life history traits, food supply and population dynamics of the white-footed mouse (Peromyscus leucopus), a species that is abundant and widely distributed across much of eastern North America. Results are based largely on a 33-year mark-and-recapture study in a forest fragment in northwest Ohio, USA. Behavioral plasticity in such reproductive traits as mating system and parental care allows this species to adjust quickly to changing environments.

Modeling biotic and abiotic influences on population size in small mammals.

Most previous work in population ecology has modeled density-dependent effects in isolation. In this paper, we concurrently modeled the effect of density-dependent and density-independent factors on the rate of population change (R ) in Peromyscus leucopus (white-footed mouse), using a Ricker equation expanded to include weather and seasonality. From 1973 to 1996, we live-trapped P.
