摘要: We studied the differences among apparent survival and capture probabilities, sex ratio, population size of Mexican endemic rodent Oryzomys chapmani associated to a chronosequence integrated by three succesional stages cloud forest. The study was made at Sierra Norte de Oaxaca region, regeneration times forests were 15 (Young), 40 (Medium), 100 (Mature) years. 227 adult specimens capture, marked, released 14 months. probabilities similar in Young Medium forests, without fluctuations across time, whereas Mature Forest dry season shows higher value. did not show variation time but showed difference, with value rainy season. significant excess males, do differ significantly from 1:1 ratio. 42 individuals hectares 302 season, both Forest.
