Close-Kin Mark-Recapture Models [PDF]

, 2019
Close-Kin Mark-Recapture (CKMR) is a recent extension of the ordinary mark–recapture methods used to estimate animal abundance and other population parameters. Where ordinary mark–recapture only consider the subsequent identification of the same animal a

Counting All the Imaginary Fish and More

, 2023
Avoiding overexploitation of marine resources requires being able to accurately estimate the size and health of a population. This thesis presents methods that improve upon existing fisheries stock assessment methods.

Schlussbericht des Thünen-Instituts für Fischereiökologie und des Thünen-Instituts für Seefischerei [PDF]

Das Projekt hatte das Ziel, eine neue Methode zur Populationsgrößenabschätzung namens Close Kin Mark-Recapture (CKMR) am Beispiel des Europäischen Stints (Osmerus eperlanus) am Thünen-Institut zu etablieren und zu testen. Die CKMR-Methode basiert auf der

Identification of Individual Fish by SNP Genotyping of emCells

Environmental DNA, Volume 8, Issue 3, May–June 2026.
emCell‐seq enables genotyping of individuals from environmental DNA. The approach uses fluorescence‐activated cell sorting to isolate cells from a target species. Isolated cells can then be analyzed with a range of ‐omics technologies. In this study, we demonstrate emCell‐seq SNP genotyping.

A Conceptual Framework and Methods for Studying the Connectivity of Fishes

Fish and Fisheries, Volume 27, Issue 2, Page 342-369, March 2026.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Pedigree‐Informed Abundance Estimation for the Endangered North Atlantic Right Whale (Eubalaena glacialis) via Gametic Mark‐Recapture

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Pedigrees can provide important data for abundance estimation by providing a means to infer the presence of individuals that might otherwise not be detected. Such information may be particularly important for endangered species, where the addition or removal of just a few individuals can make the difference between population growth and ...

Simulation‐Based Inference for Close‐Kin Mark‐Recapture: Implications for Small Populations and Nonrandom Mating

Environmetrics, Volume 36, Issue 8, December 2025.
ABSTRACT Close‐kin mark‐recapture (CKMR) uses data on the frequency of kin pair relationships (e.g., parent‐offspring, half‐siblings) in genetic samples from animal populations to estimate parameters such as abundance and adult survival probability.

Genomic Insights Into the Origin, Decline and Recovery of the Once Critically Endangered Iberian Lynx

Molecular Ecology, Volume 34, Issue 23, December 2025.
ABSTRACT The Iberian lynx was at the brink of extinction by the year 2000 but has since then, and thanks to intensive conservation measures, gone through a remarkable recovery, providing a much‐welcomed and encouraging conservation success story.

Putting Regional Fisheries Management Organisations' Climate Change House in Order

Fish and Fisheries, Volume 26, Issue 6, Page 1040-1047, November 2025.
ABSTRACT Climate change is expected to have significant impacts on the biology, abundance and distribution of transboundary fish stocks, not only among neighbouring countries within the jurisdictions of regional fisheries management organisations (RFMOs) but also between adjacent RFMOs.
