Abstract: | We study the influence of age and sex on survival and spatial fidelity of moufl on (Ovis gmelini) in the Caroux-Espinouse massif. Survival and movement probabilities are estimated through a Bayesian analysis of an age-dependent capture-recapture model. Prior information is based on external data, namely on radio-tracked animals. Recapture rates differed between age, sexes, and areas. Whatever the area, survival of males and females less than 5 years old was high and decreased for older animals, particularly males. Female spatial fidelity was high; males were as faithful as females to their capture area in their first 2 years of life but gradually used distinct areas in two successive years as they were getting older. |
