| Izvleček: | Population dinamics of the big-eared climbing rat (Ototylomys phyllotis) was studied in a subdeciduous tropical rainforest located at Rancho Hobonil, Tzucacab, Yucatan using a mark-recapturetechnique, from April 1996 to April 1998 during five nights per 24 months. The minimum-numberknown-alive technique (MNKA) was used to estimate population size. We captured 123 rats, 52% werefemales and 48% males. The sex ratio was 1:1 during this study. Density ranged from 10 to 46 ind./ha. And was not significantly correlated with precipitation (p>0.05). Presence of reproductive individuals from both sexes during the majorities of the studied months and the reproductive activity from females suggest a continuous poliestric pattern for this species. |
