Evaluating trends in abundance of immature green turtles, Chelonia mydas, in the Greater Caribbean [PDF]
Many long-lived marine species exhibit life history traits. that make them more vulnerable to overexploitation. Accurate population trend analysis is essential for development and assessment of management plans for these species. However, because many of

In capture–recapture studies, recycled individuals occur when individuals lose all of their tags and are recaptured as though they were new individuals. Typically, the effect of these recycled individuals is assumed negligible. Through a simulation‐based

Taking individual heterogeneity in mortality risks into account in demographic studies of wild animal populations: development and use of statistical models. [PDF]
The Cormarck-Jolly-Seber model incorporating frailty implemented in WinBUGS, using the 9000 kittiwake’s dataset monitorized during 22 years, showed that the convergence is very low over computational view. We developed different kind of multistate model,

Seasonal body mass dynamics mediate life‐history trade‐offs in a hibernating mammal
We tested a suite of ecological hypotheses to explain variation in seasonal body mass dynamics of a fat‐storing mammalian hibernator. We further demonstrated that pre‐hibernation mass gain in ground squirrels mediates an annual allocation trade‐off between current and future reproduction as the squirrels forage and rear young under predation risk ...

We investigated the breeding season, growth rate and dispersal of the dark chub, Candidia sieboldii, an endangered species in Japan. A mark–release–recapture survey was performed in three branches of the Ishizu River system in Osaka Prefecture, Japan ...

We evaluated whether the Indo-Pacific bottlenose dolphins around the fast-developing island of Mayotte are threatened. We used opportunistic photo-identification data and capture-mark-recapture models to estimate key demographic parameters and then ...

We used pattern recognition software to correct misidentifications in a 15‐year photographic database of the last, vulnerable West African giraffe population in Niger. After revealing substantial methodological errors that had inflated population estimates by nearly 19%, we corrected individual encounter histories and applied capture‐mark‐recapture ...

Covariantes continuas individuales dependientes del tiempo y el modelo de Cormack–Jolly–Seber [PDF]
The Cormack–Jolly–Seber model provides the basic framework for analyzing the survival of animals in open populations using capture–recapture data. Extensions of this model have already been developed that allow the survival and capture probabilities to ...

The demography of the lizard Tropidurus torquatus (Squamata, Tropiduridae) in a highly seasonal Neotropical savanna [PDF]
The demography of a population of Tropidurus torquatus was studied from March 1996 until December 1998, in the Cerrado biome of the Central Brazil, using the method of capture and recapture.
