Although over winter survival was very low (, four known individuals) between the two years of this study (An- derson 2004), we did not include those four individuals in the data set for the second year. Rainfall amounts from the Ohio Agricultural Research & Development Center (OARDC) weather station on Miami Universi- ty's Oxford campus ( van ) were totaled for each summer month (June - August) in 1999 and 2000. The OARDC is located within the center of the study area. Statistical analyses Data on the proportion of mice trapped for their sec- ond capture in the exterior, edge, or interior habitats, or not subsequently recaptured, based on the three initial capture habitats (, exterior, edge, or interior) were compiled (see Table 2). The data set was analyzed with PROC CATMOD using chi-square tests to determine whether captures among habitats differed in relation to patch size, surro
