Titulo: "Bayesian capture-recapture analysis: an application in modeling 
semelparity of a neotropical didelphid marsupial"

Local: Sala C-116, Centro de Tecnologia, Cidade Universitária.



Resumo:
We develop a series of Bayesian statistical models for estimating survival 
of a neotropic didelphid marsupial, the Brazilian gracile mouse opossum 
(Gracilinanus microtarsus). These models are based on the Cormack-Jolly-
Seber model (Cormack, 1964; Jolly, 1965; Seber, 1965) with both survival and 
recapture rates expressed as a function of covariates using a logit link. 
The proposed models allow taking into account heterogeneity in capture 
probability caused by the existence of different groups of individuals in 
the population. The models were applied to two cohorts (Cohort 2000 and 
Cohort 2001) with the first one including 14 and the second one 15 sampling 
occasions. The best models for each of the cohorts indicate that it G. 
microtarsus is best described as partially semelparous, a condition in which 
mortality after the first mating is high but graded over time, with a 
fraction of males surviving for a second breeding season (Boonstra, 2005).
