Group heterogeneity in the Jolly-Seber-Tag-Loss model

, 2014
Mark–recapture experiments involve capturing individuals from populations of interest, marking and releasing them at an initial sample time, and recapturing individuals from the same populations on subsequent occasions.

Dinámica poblacional y fidelidad de refugio por Carollia brevicauda (Quiroptera: Phyllostomidae) en un refugio artificial, en los Andes nororientales de Colombia

Mammalogy Notes, 2022
Los refugios imponen presiones selectivas a los murciélagos. Los refugios proporcionan sitios de apareamiento, hibernación y crianza; promueven interacciones sociales, digestión de alimentos; y ofrecen protección contra el clima adverso y los ...

The Jolly-Seber-Tag-Loss model with group heterogeneity

, 1969
Mark-recapture experiments are performed to estimate population parameters such as survival probabilities. Animals are captured, tagged, released, and recaptured at subsequent time periods in order to obtain parameter information.

Comparison of tributarysurvival estimates of steelhead using Cormack-Jolly-Seber and Barker models: implications forsampling effort and designs

, 2015
We conducted simulations to compare the precision and bias of survival estimates from Cormack–Jolly–Seber (CJS) and Barker models to known parameter values based on empirical data for steelhead/resident Rainbow Trout Oncorhynchus mykiss from the John Day

Decadal banding efforts pay off: Assessing Chinese Crested Tern conservation through resighting data

Avian Research
The critically endangered Chinese Crested Tern (Thalasseus bernsteini, CCT) and its common flocking companion, the Greater Crested Tern (Thalasseus bergii, GCT), have been the focus of targeted recovery efforts in the Jiushan Archipelago of Zhejiang ...

Predicting citril finch Carduelis citrinella response to climatic change: An analysis of survival and recruitment probabilities in relation to meteorological covariates

Animal Biodiversity and Conservation
Understanding the impact of climate change on species’ demography is essential for assessing their vulnerability to environmental shifts. We analysed a dataset of 6,967 citril finches Carduelis citrinella captured at a Pyrenean site between 1991 and ...

Climatic variation influences annual survival of an island‐breeding tropical shorebird

Journal of Avian Biology
Global biodiversity loss is a major environmental concern. The wildlife on islands are particularly vulnerable to threats posed by alien predators, habitat loss and overexploitation.

QUANTIFYING THE EFFECTS OF UNEQUAL CATCHABILITIES ON JOLLY-SEBER ESTIMATORS VIA SAMPLE COVERAGE

, 2011
[[abstract]]Using the concept of sample coverage, we derive an approximation of the bias in the Jolly-Seber population size estimators due to heterogeneity of capture probabilities.
