Combining individual and close-kin mark-recapture to design an effective wildlife population survey. [PDF]

Ecology
Abstract Close‐kin mark–recapture (CKMR) is a promising approach for assessing population size of species that have been difficult to survey using more traditional methods. Here, we combine individual and close‐kin mark–recapture in a single modeling framework (ICKMR) and provide an example of study design using this approach for Pacific walrus ...

Expanding the feasibility of fish and wildlife assessments with close‐kin mark–recapture

Ecosphere, 2020
Close‐kin mark–recapture (CKMR) is a powerful new method for the assessment of fish and wildlife population dynamics. Unlike traditional mark–recapture techniques, the use of kinship as an identifying mark is robust to many forms of capture heterogeneity

Methods to estimate marine functional connectivity: A primer. [PDF]

Ecol Appl
Abstract Organism movement is a key process in the transfer of individuals, genes, functional traits, matter, and energy among habitat patches, at sea and across the land–sea interface. The resulting fluxes, collectively termed marine functional connectivity (MFC), underpin planetary health and an array of ecosystem services.

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

, 2019
1. 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 ...
