Demography and Population Dynamics of the Lacertid Lizard Podarcis Bocagei in North-West Spain [PDF]
[Abstract] The demography and life-history traits of a population of the lacertid lizard Podarcis bocagei in north-west Spain were investigated. Most of the conclusions presented are based on mark-recapture studies carried out over a 2-year period ...

Estimation of Population Growth Rate using Jolly-Seber Method and Robust Design [PDF]
Mark-Recapture method for open population commonly use Jolly-Seber method. This method assumes that all animals are equally likely to be caught in each sample (the equal catchability). This objects are making introduction of Mark-Recapture method for open population and using the robust design that combine a open population method with close population

An understanding of the survival probability and abundance of endangered species is critical for their effective conservation and management. In this study, long-term capture-mark-recapture data were used to estimate the apparent survival probability and

The goal of this study was to assess the population structure of Pseudis bolbodactyla Lutz, 1925 using natural markings to identify individuals. Recruitment, survival, and population size estimations were obtained using the Jolly-Seber stochastic method.

When is a parasite not a parasite? Effects of larval tick burdens on white-footed mouse survival [PDF]
Many animal species can carry considerable burdens of ectoparasites: parasites living on the outside of a host's body. Ectoparasite infestation can decrease host survival, but the magnitude and even direction of survival effects can vary depending on the

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 ...
