| Description | Genic heterozygosity values in the 4 spp. of Peromyscus (Rodentia: Cricetidae) in this study span the range in variability known for the genus. Heterozygosity is high in populatons of P. maniculatus (.hivin.H = 0.11-0.15) and low in P. boylii and P. truei (.hivin.H < 0.05). P. californicus is strongly differentiated at several polymorphic loci between geographically northern and southern population groups. In this species heterozygosity values vary geographically from 0.03-0.12, with the higher values found in the zone of contact and in southern populations. Genetic variability measured by variability in epigenetic characters is significantly correlated with the electrophoretic measure of variability. Habitat niche width was chosen as the most appropriate measure of environmental heterogeneity in these species. Neither the electrophoretic nor the epigenetic measure of genetic variability is significantly correlated with species niche width. The potential impact of geographic differentiation within a species, population patterns and reproductive potential on levels of variability is discussed. Hastings was one of four study sites. Hastings Natural History Reservation, the third site, is located in the Santa Lucia Mountains in upper Carmel Valley (Monterey Co.: 14 mi SE Carmel Valley, 36?22'N, 121?33'W). All four species, P. maniculatus, P. boylii, P. truei, and P. californicus, were present at Hastings. TABLE 4.-Summary of numbers of Peromyscus captured. Numbers given are the total number of animals caught in each habitat from July 1975 through March 1977. Relative numbers (the number of individuals per 100 trap nights) are given in parentheses. Marked animals were counted only once in each time period. |
