Long‐term apparent survival of a cold‐stunned subpopulation of juvenile green turtles
Ecosphere, 2022 Understanding the effects of extreme weather on animal populations is fundamental to ecological and conservation sciences and species management. Climate change has resulted in both warm and cold temperature extremes, including an increased frequency of ...

HOME RANGE AND MICROHABITAT ASSOCIATIONS OF THE SOUTHERN RED-BACKED VOLE (MYODES GAPPERI) IN NEW HAMPSHIRE FORESTS [PDF]
, 2018 Resources, such as food and shelter, are unevenly distributed across the landscape at both macro and micro scales. Home range is one measure of space use that reflects an individual’s resource requirements (e.g., microhabitat characteristics) and ...

The Journal of Wildlife Management, Volume 90, Issue 1, January 2026.We present an approach for estimating wildlife abundance from unstructured aerial surveys. We combine a spatial model for count data with auxiliary information on detection probability. This framework is intended to be flexible, requiring lower survey costs and less computation time than other alternatives for estimating abundance.

Estimation of Time-Specific Survival Rates from Tag-Resighting Samples: A Generalization of the Jolly-Seber Model [PDF]
Biometrics, 1983 On étudie le comportement d'animaux capturés, marqués puis remis en liberté, en les observent plutot qu'en les recapturent on étudie ainsi l'influence de la capture et du marquage sur leur survie. On généralise ici les modèles de Cormack et de Jolly-Seber, qui ont le défaut de considérer que la capture n'influe pas sur leur survie, et dont les ...

River Research and Applications, Volume 42, Issue 1, Page 40-59, January 2026.ABSTRACT The upstream migration of juvenile American eels (Anguilla rostrata) is frequently obstructed by dams and other in‐stream barriers, leading to habitat loss and fragmentation, factors that are believed to contribute to the species' population decline.

A range‐wide full‐annual‐cycle model informs conservation of a declining migratory shorebird
Journal of Applied Ecology, Volume 63, Issue 1, January 2026.The tōrea population decline suggests the need for a higher IUCN threat classification and a conservation strategy (e.g. habitat protection and restoration) targeting multiple demographic rates across the annual cycle of tōrea. Our novel approach using population growth rates to link fragmented local, season‐specific data to model range‐wide full ...

Modelos jerárquicos de marcaje–recaptura: un marco para la inferencia de procesos demográficos [PDF]
, 2004 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 ...

The average laboratory samples a population of 7,300 Amazon Mechanical Turk workers [PDF]
, 2015 Using capture-recapture analysis we estimate the effective size of the active Amazon Mechanical Turk (MTurk) population that a typical laboratory can access to be about 7,300 workers.

Scientia Marina, 2007 Survival probabilities of loggerhead sea turtles (Caretta caretta) are estimated for the first time in the Mediterranean by analysing 3254 tagging and 134 re-encounter data from this region. Most of these turtles were juveniles found at sea.
