Abstract
The demography of Peromyscus leucopus and P. maniculatus was studied in deciduous 4 forest sites in Indiana, Virginia, Ohio and Pennsylvania. In Virginia and Pennsylvania the 2 species were sympatric; at the other sites P. leucopus was the only species present. Peak densities varied greatly among sites (range: Indiana P. leucopus peak = 30/ha; Pennsylvania P. maniculatus peak = 120/ha). Except for an apparent synchronous high in 1981, there was no strong temporal concordance of peaks or lows among sites over 1979-1986. 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. Local processes appear to be more important than regional ones in Peromyscus demography. -from Authors
