The demography of Peromyscus leucopus and Peromyscus maniculatus was studied from 1979 to 1986 in four deciduous forest sites in Indiana, Virginia, Ohio, and Pennsylvania. In two sites (Virginia and Pennsylvania) the two species were sympatic; at the other two sites, Peromyscus leucopus was the only species present. Peak densities varied greatly among sites (range: Indiana Peromyscus leucopus peak = 30/ha; Pennsylvania Peromyscus maniculatus peak = 120/ha). Except for an apparent synchronous high in 1981, there was no strong temporal concordance of peaks or lows among sites. Breeding seasons were of comparable length at all four sites and typically showed a late summer (August–September) hiatus followed by some fall breeding. There was no consistent relationship among sites between over-winter survival and peak density the following summer or between the percentage of adult females pregnant and peak density. Thus, our data suggest that local processes are more important than regional ones in Peromyscus demography.

Breeding Seasons

Reproductive characteristics of Peromyscus maniculatus in Manitoba and Peromyscus leucopus in Ontario were compared in order to determine the extent to which breeding compensates for relatively short breeding seasons. Peromyscus maniculatus had a shorter breeding season than P. leucopus, but frequency of litters, litter size, and age of females at sexual maturity were the same for both species. A comparison of breeding characteristics among Peromyscus from different geographic areas indicated that basic reproductive characteristics do not vary in relation to length of the breeding season.In general, we have no evidence that the basic reproductive characteristics of Peromyscus vary in relation to length of the breeding season. Peromyscus with short breeding seasons, on average, must have a lower annual reproductive rate than Peromyscus with long breeding seasons.
