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)

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

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 ...

Simulation‐Based Spatially Explicit Close‐Kin Mark–Recapture [PDF]
Molecular Ecology ResourcesABSTRACT Estimating the size of wild populations is a critical priority for ecologists and conservation biologists, but tools to do so are often labour intensive and expensive. A promising set of newer approaches are based on genetic data, which can be cheaper to obtain and less invasive than information from more direct observation.

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

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‐

Close-kin mark-recapture methods to estimate demographic parameters of mosquitoes. [PDF]
PLoS Computational Biology, 2022 Close-kin mark-recapture (CKMR) methods have recently been used to infer demographic parameters such as census population size and survival for fish of interest to fisheries and conservation.

Validation of close‐kin mark–recapture (CKMR) methods for estimating population abundance [PDF]
Methods in Ecology and Evolution, 2019 Abstract 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 using standard mark–recapture (MR) and the close‐kin mark–recapture (CKMR) method.

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