Age-structured Jolly-Seber model expands inference and improves parameter estimation from capture-recapture data. [PDF]

open access: yesPLoS ONE, 2021
Understanding the influence of individual attributes on demographic processes is a key objective of wildlife population studies. Capture-recapture and age data are commonly collected to investigate hypotheses about survival, reproduction, and viability ...

Parameter redundancy in Jolly‐Seber tag loss models [PDF]

open access: yesEcology and Evolution, 2021
Capture–recapture experiments are conducted to estimate population parameters such as population size, survival rates, and capture rates. Typically, individuals are captured and given unique tags, then recaptured over several time periods with the ...

Understanding the impact of correlation within pair‐bonds on Cormack–Jolly–Seber models [PDF]

open access: yesEcology 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

Population Dynamics of the Florida Softshell Turtle (Apalone ferox) in a Protected Spring Ecosystem [PDF]

open access: yesBiology
The Florida softshell turtle, Apalone ferox, is considered common and found in many different types of freshwater habitats throughout its range. However, despite its prevalence where it occurs, little is understood about the species’ life history and ...

Survival Estimation Using Multistate Cormack–Jolly–Seber Models—The Case of the Bearded Vulture Gypaetus barbatus in Spain [PDF]

open access: yesAnimals
The 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.

Rcapture: Loglinear Models for Capture-Recapture in R [PDF]

open access: yesJournal 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

Using Known Births to Account for Delayed Marking in Population Estimation of North Atlantic Right Whales [PDF]

open access: yesEcology and Evolution
Population estimation using capture–recapture modeling typically requires that individuals are identifiable by unique marks. North Atlantic right whales (Eubalaena glacialis) can be identified by natural callosity patterns on their heads that are ...

Large, but Dispersal‐Limited Populations of the Marsh Fritillary Euphydryas aurinia Persist on Abandoned Military Training Areas Three Decades After the End of the Cold War [PDF]

open access: yesEcology and Evolution
Military training areas can host important biodiversity, due to the preservation of diverse, nutrient‐poor historical cultural landscapes and an insect‐friendly disturbance regime.

Similar Survival Rates of Territorial and Sneaker Males in a Polymorphic Damselfly: A Multi‐Year Study [PDF]

open access: yesEcology and Evolution
Male 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 ...
