CMRnet: An r package to derive networks of social interactions and movement from mark–recapture data

open access: yesMethods in Ecology and Evolution, 2020
Long‐term capture–mark–recapture data provide valuable information on the movements of individuals between locations, and the contemporary and/or co‐located captures of individuals can be used to approximate the social structure of populations.

Estimating effective population size using close‐kin mark–recapture

open access: yesMethods in Ecology and Evolution
Close‐kin mark–recapture (CKMR) is a method that allows estimating population census size, among other parameters, through the observed number of pairs that are close‐kin including parent–offspring pairs (POPs) and half‐sibling pairs (HSPs).

Validation of close‐kin mark–recapture (CKMR) methods for estimating population abundance

open access: yesMethods in Ecology and Evolution, 2019
Knowing how many individuals there are in a population is a fundamental problem in the management and conservation of freshwater and marine fish. We compare abundance estimates (census size, Nc) in seven brook trout Salvelinus fontinalis populations ...

Integrating high‐speed videos in capture‐mark‐recapture studies of insects

open access: yesEcology and Evolution, 2020
Capture–mark–recapture (CMR) studies have been used extensively in ecology and evolution. While it is feasible to apply CMR in some animals, it is considerably more challenging in small fast‐moving species such as insects.

A comparison of 3 common methods for monitoring gopher tortoises

open access: yesWildlife Society Bulletin
Wildlife biologists choose monitoring techniques for threatened and endangered species that optimize time, resources, data quantity, and data quality.

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.

Modeling the distances traveled by flying insects based on the combination of flight mill and mark-release-recapture experiments

open access: yesEcological Modelling, 2019
The number of invasive species is increasing throughout the world. One of the corner stones to successfully control them is to better estimate their dispersal capabilities.

The estimation of grizzly bear density through hair‐snagging techniques above the tree line

open access: yesWildlife Society Bulletin, 2015
Assessing grizzly bears' (Ursus arctos) abundance in the Arctic has been challenging because of the large scale of their movements and the remoteness of field locations.

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

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

A Cretaceous peak in family-level insect diversity estimated with mark–recapture methodology

open access: yesProceedings of the Royal Society B, 2019
The history of insects’ taxonomic diversity is poorly understood. The two most common methods for estimating taxonomic diversity in deep time yield conflicting results: the ‘range through’ method suggests a steady, nearly monotonic increase in family ...
