| Popis: | Osgoodomys banderanus (Osgood's deermouse) was studied in January 2006 and 2007 in north-central Colima, Mexico. During 8 nights each year, five mark-recapture grids were established with elevated and ground traps. For 16,000 trap-nights, 123 individuals were captured 385 times (comprising 9.4% of captures on grids); one-third of captures were in elevated traps. The ratio of males to females was 1.51:1 (significantly different from 1:1). No sexual dimorphism in mass was detected, 84.4% were adults, and 41.5% of adult females were pregnant or lactating. Average distance between successive captures was 19.62 m, and average distance from a central point of capture was 12.74 m. Osgoodomys banderanus was captured on 6 of 10 grids (densities 0.76–30.55 individuals/ha). Probability of capture or recapture was influenced by trapping night, with probabilities peaking on nights 6 and 7. Habitat preferences were based on 14 environmental variables taken at each trapping station. Logistic regression indicate... |
