Long-term trends in the use of a protected area by small cetaceans in relation to changes in population status

open access: yesGlobal Ecology and Conservation, 2014
The requirement to monitor listed species in European designated sites is challenging for long-lived mobile species that only temporarily occupy protected areas.

Reliability of trans‐generational genetic mark–recapture (tGMR) for enumerating Pacific salmon [PDF]

open access: yesEvolutionary Applications
As Pacific salmon (Oncorhynchus spp.) decline across much of their range, it is imperative to further develop minimally invasive tools to quantify population abundance.

A Mark-Recapture Approach to Estimating Item Pool Compromise. [PDF]

open access: yesAppl Psychol Meas
Testing organizations routinely investigate if secure exam material has been compromised and is consequently invalid for scoring and inclusion on future assessments. Beyond identifying individual compromised items, knowing the degree to which a form is compromised can inform decisions on whether the form can no longer be administered or when an item ...

Application of network theory to mark recapture data allows insights into population structure of two Heliconius species [PDF]

open access: yesNetwork Biology, 2015
By noting the spatial location of captured individuals mark-recapture studies create a collection of discrete events spread in space and time. This setup is appropriate for network modeling where the vertices (or nodes) are the points of capture and ...

Close-kin mark-recapture informs critically endangered terrestrial mammal status. [PDF]

open access: yesSci Rep, 2023
Reliable information on population size is fundamental to the management of threatened species. For wild species, mark-recapture methods are a cornerstone of abundance estimation. Here, we show the first application of the close-kin mark-recapture (CKMR)

Chew-cards can accurately index invasive rat densities in Mariana Island forests [PDF]

open access: yesNeoBiota, 2022
Rats (Rattus spp.) are likely established on 80–90% of the world’s islands and represent one of the most damaging and expensive biological invaders. Effective rat control tools exist but require accurate population density estimates or indices to inform ...

The Analysis of Continuous Mark-Recapture Data [PDF]

open access: yes, 2006
The purpose of this thesis is to develop a general methodology for the analysis of continuously sampled data from open populations. The thesis consists of four parts and one appendix. The four parts may be read independently of each other. The appendix consists of a submitted article based on the developments in Part III.

Estimation fish stock and composition using mark recapture studies in floodplain lake, Jambi City

open access: yesDepik Jurnal, 2023
Fish stock assessment can be estimated by dependent and independent sampling; Mark-recapture studies is a part of independent sampling method that can be used for it. This study was conducted in 2018 using purposive sampling methods.

Accurate recapture identification for genetic mark–recapture studies with error-tolerant likelihood-based match calling and sample clustering [PDF]

open access: yesRoyal Society Open Science, 2016
Error-tolerant likelihood-based match calling presents a promising technique to accurately identify recapture events in genetic mark–recapture studies by combining probabilities of latent genotypes and probabilities of observed genotypes, which may ...
