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

Scientific Reports, 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)

Evaluating the suitability of close‐kin mark‐recapture as a demographic modelling tool for a critically endangered elasmobranch population [PDF]

Evolutionary Applications, 2023
Estimating the demographic parameters of contemporary populations is essential to the success of elasmobranch conservation programmes, and to understanding their recent evolutionary history. For benthic elasmobranchs such as skates, traditional fisheries‐

Population abundance in arctic grayling using genetics and close‐kin mark‐recapture [PDF]

Ecology and Evolution, 2021
Arctic Grayling (Thymallus arcticus) are among the most widely distributed and abundant freshwater fish in the Yukon Territory of Canada, yet little information exists regarding their broad and fine‐scale population structures or the number and size of ...

Considering sampling bias in close‐kin mark–recapture abundance estimates of Atlantic salmon [PDF]

Ecology and Evolution, 2021
Genetic methods for the estimation of population size can be powerful alternatives to conventional methods. Close‐kin mark–recapture (CKMR) is based on the principles of conventional mark–recapture, but instead of being physically marked, individuals are

Low levels of sibship encourage use of larvae in western Atlantic bluefin tuna abundance estimation by close-kin mark-recapture [PDF]

Scientific Reports, 2022
Globally, tunas are among the most valuable fish stocks, but are also inherently difficult to monitor and assess. Samples of larvae of Western Atlantic bluefin tuna Thunnus thynnus (Linnaeus, 1758) from standardized annual surveys in the northern Gulf of

Robustness of close‐kin mark–recapture estimators to dispersal limitation and spatially varying sampling probabilities [PDF]

Ecology and Evolution, 2020
Close‐kin mark–recapture (CKMR) is a method for estimating abundance and vital rates from kinship relationships observed in genetic samples. CKMR inference only requires animals to be sampled once (e.g., lethally), potentially widening the scope of ...

Absolute abundance of southern bluefin tuna estimated by close-kin mark-recapture [PDF]

Nature Communications, 2016
Accurate determination of population size for highly-mobile marine animals is often prohibitively difficult. Here, Bravingtonet al.estimate the abundance of southern bluefin tuna using a method based on the number of parent-offspring pairs detected ...

Spatial close-kin mark-recapture methods to estimate dispersal parameters and barrier strength for mosquitoes. [PDF]

PLoS Computational Biology
Close-kin mark-recapture (CKMR) methods have recently been used to infer demographic parameters for several aquatic and terrestrial species. For mosquitoes, the spatial distribution of close-kin pairs has been used to estimate mean dispersal distance, of

A simulation-based evaluation of methods for estimating census population size of terrestrial game species from genetically-identified parent-offspring pairs [PDF]

PeerJ, 2023
Estimates of wildlife population size are critical for conservation and management, but accurate estimates are difficult to obtain for many species. Several methods have recently been developed that estimate abundance using kinship relationships observed
