Estimation by capture-recapture of recruitment and dispersal over several sites

摘要: Dispersal in animal populations is intimately linked with accession to reproduction, i.e. recruitment, and population regulation. processes are thus a key component of dynamics the same extent as reproduction or mortality processes. Despite growing interest spatial aspects dynamics, methodology for estimating dispersal, particular relation limited. In many populations, vertebrates, impossibility following individuals over space time an exhaustive way leads need frame estimation dispersal context capture-recapture methodology. We present here class age-dependent multistate models simultaneous natal breeding recruitment. These suitable which marked at birth then recaptured several sites. Under simple constraints, they can be used where non-breeders not observed, often case colonial waterbirds monitored on their grounds. Biological questions addressed by comparing differing structure, according generalized linear model philosophy broadly illustrate potential this approach analysis recruitment roseate tern Sterna dougallii.
