 Population Variables



 Trap success varied per study site, but the mean for all study sites was 0.07,
with 2755 total trap nights. Of the 218 captures, 78% (n=164) were recaptures
(Table 9). Total animals captured at all study sites consisted of 32 males and 22
females, which resulted in a sex ratio of 1.6:1, favoring males. Weights of adult
woodrats fluctuated considerably throughout the study period; a phenomenon also
observed by Fitch and Rainey (1956). A t-test demonstrated that although male
woodrats weighed significantly more than females, their body measurements were
not larger (p=0.05). (The mean values for weight and body measurements are
presented in Table 10.)
 Reproduction occurred throughout the year. A Chi-square test demonstrated
that no significant differences existed in reproductive activity for males or females
between months or seasons (p=0.05). However, peaks occurred in April and
November for males, and July and November for females (Fig. 2).
