Understanding the impact of correlation within pair‐bonds on Cormack–Jolly–Seber models [PDF]
Ecology and Evolution, 2021 The Cormack–Jolly–Seber (CJS) model and its extensions have been widely applied to the study of animal survival rates in open populations. The model assumes that individuals within the population of interest have independent fates. It is, however, highly

Survival Estimation Using Multistate Cormack–Jolly–Seber Models—The Case of the Bearded Vulture Gypaetus barbatus in Spain [PDF]
AnimalsThe bearded vulture (Gypaetus barbatus) is an endangered species with a specialist osteophagous (bone) diet. We estimated the survival and productivity of this vulture in the Aragonese Pyrenees, where the main population of the species in Europe is found.

Age-Specific Demographic Response of a Long-Lived Scavenger Species to Reduction of Organic Matter in a Landfill [PDF]
Animals, 2023 Food availability shapes demographic parameters and population dynamics. Certain species have adapted to predictable anthropogenic food resources like landfills. However, abrupt shifts in food availability can negatively impact such populations.

Rcapture: Loglinear Models for Capture-Recapture in R [PDF]
Journal of Statistical Software, 2007 This article introduces Rcapture, an R package for capture-recapture experiments. The data for analysis consists of the frequencies of the observable capture histories over the t capture occasions of the experiment. A capture history is a vector of zeros

Similar Survival Rates of Territorial and Sneaker Males in a Polymorphic Damselfly: A Multi‐Year Study [PDF]
Ecology and EvolutionMale alternative reproductive tactics (ARTs) have been documented across diverse taxa and typically involve a male morph that defends resources to attract females and an alternate morph that exploits this behavior to obtain matings by stealth ...

Continuous time-dependent Individual covariates and the Cormack-Jolly-Seber model [PDF]
Animal Biodiversity and Conservation, 2004 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 ...

Age‐specific survival of reintroduced swift fox in Badlands National Park and surrounding lands [PDF]
Wildlife Society Bulletin, 2016 In 2003, a reintroduction program was initiated at Badlands National Park (BNP), South Dakota, USA, with swift foxes (Vulpes velox) translocated from Colorado and Wyoming, USA, as part of a restoration effort to recover declining swift fox populations ...

Salmon Louse Infestation Impairs the Long‐Term Survival of Sea‐Run Brown Trout [PDF]
Ecology and EvolutionAnadromous salmonids, including sea‐run brown trout, are exposed to ectoparasitic salmon lice during their sea migrations. The development of intensive aquaculture in coastal areas has promoted louse epidemics by substantially increasing the number of ...

Demography and Behaviour of Teinopodagrion oscillans (Odonata: Megapodagrionidae) in a Protected Area of the Colombian Andean Region [PDF]
InsectsThe demography and behaviour of Teinopodagrion oscillans was studied in a protected area in the Andean region of Colombia. Adult damselflies were individually marked, and using their recapture histories, we estimated survival, longevity, sex ratio, and ...
