Bayesian mark–recapture–resight–recovery models: increasing user flexibility in the BUGS language

Ecosphere, 2021
Estimating demographic parameters of interest is a critical component of applied conservation biology and evolutionary ecology, where demographic models and demographic data have become increasingly complex over the last several decades.

Integrating growth and survival models for flexible estimation of size‐dependent survival in a cryptic, endangered snake

Ecology and Evolution, 2022
Estimates of demographic rates for animal populations and individuals have many applications for ecological and conservation research. In many animals, survival is size‐dependent, but estimating the form of the size–survival relationship presents ...

Estimating the population structure of Javan rhinos (Rhinoceros sondaicus) in Ujung Kulon National Park using the mark- recapture method based on video and camera trap identification

Pachyderm, 2011
The population structure of the Javan rhino (Rhinoceros sondaicus) in Ujung Kulon National Park (NP) in Banten, Indonesia was assessed using visual identification and mark-recapture estimation.

Monitoring Brazilian Cavefish: Ecology and Conservation of Four Threatened Catfish of Genus Ituglanis (Siluriformes: Trichomycteridae) from Central Brazil

Diversity, 2021
We investigated population parameters using the capture-mark-recapture method (Ituglanis passensis and I. bambui) and visual censuses (I. epikasrticus and I. ramiroi).

Home‐site fidelity and homing behavior of the big‐headed turtle Platysternon megacephalum

Ecology and Evolution, 2021
Site fidelity refers to the restriction of dispersal distance of an animal and its tendency to return to a stationary site. To our knowledge, the homing ability of freshwater turtles and their fidelity is reportedly very low in Asia.

Towards the mother-of-all-models: customised construction of the mark-recapture likelihood function [PDF]

Animal Biodiversity and Conservation, 2004
With a proliferation of mark–recapture models and studies collecting mark–recapture data, software and analysis methods are being continually revised. We consider the construction of the likelihood for a general model that incorporates all the features ...

Reliability of catch per unit effort (CPUE) for evaluation of reintroduction programs – A comparison of the mark-recapture method with standardized trapping

Knowledge and Management of Aquatic Ecosystems, 2011
Catch per unit effort (CPUE) is used as a standardized trapping method by local fishermen and in monitoring studies. In this study, CPUE was compared with population estimates made with a capture-recapture method based on the passive ...

Trap configuration and spacing influences parameter estimates in spatial capture-recapture models. [PDF]

PLoS ONE, 2014
An increasing number of studies employ spatial capture-recapture models to estimate population size, but there has been limited research on how different spatial sampling designs and trap configurations influence parameter estimators.

Mobile application for wildlife capture–mark–recapture data collection and query

Wildlife Society Bulletin, 2013
Capture–mark–recapture (CMR) approaches are often used in the management and conservation of wildlife species and effective approaches to estimate populations rely on accurate data‐collection techniques.

Evidence of high longevity in an Island lacertid, Teira dugesii (Milne-Edwards, 1829). First data on wild specimens

Acta Herpetologica, 2012
Using the technique of capture, mark and recapture, here is reported a case of high longevity in the Madeiran lizard, Teira dugesii. It is one of the highest reported values for lacertid lizards (16 years or more) in a wild population.
