Seasonal survival probabilities suggest low migration mortality in migrating bats. [PDF]
Migration is adaptive if survival benefits are larger than costs of residency. Many aspects of bat migration ecology such as migratory costs, stopover site use and fidelity are largely unknown.

Long-term demography of a reintroduced population of endangered falcons
We examined long-term demography of an endangered subspecies, the Northern Aplomado Falcon (Falco femoralis septentrionalis), in South Texas, USA. The population has been managed and monitored since reintroductions began in 1993.

Annual survival estimation of migratory songbirds confounded by incomplete breeding site-fidelity: study designs that may help [PDF]
Many species of bird exhibit varying degrees of site–fidelity to the previous year’s territory or breeding area, a phenomenon we refer to as incomplete breeding site–fidelity. If the territory they occupy is located beyond the bounds of the study area or

Age‐ and sex‐specific survival of the Gunnison's prairie dog (Cynomys gunnisoni)
Age‐ and sex‐specific survival rates are essential for understanding animal population dynamics and discerning environmental influences on population parameters.

State space and movement specification in open population spatial capture-recapture models. [PDF]
With continued global changes, such as climate change, biodiversity loss, and habitat fragmentation, the need for assessment of long-term population dynamics and population monitoring of threatened species is growing.

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 ...

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 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 ...

Modelos jerárquicos de marcaje–recaptura: un marco para la inferencia de procesos demográficos [PDF]
The development of sophisticated mark–recapture models over the last four decades has provided fundamental tools for the study of wildlife populations, allowing reliable inference about population sizes and demographic rates based on clearly formulated ...
