Estimation of Parental Abundance Using Hierarchical Bayesian Modeling With Data Augmentation [PDF]

Ecol Evol
Pedigree accumulation estimators leverage the fact that each offspring in a cohort is genotypically “marked” by its parents and represent a recent and promising toolset for estimating population dynamics. We developed a hierarchical Bayesian pedigree accumulation estimator and compared it to previously evaluated non‐parametric approaches.

Effective Population Size Estimation in Large Marine Populations: Considering Current Challenges and Opportunities When Simulating Large Data Sets With High-Density Genomic Information. [PDF]

Evol Appl
ABSTRACT Next‐generation‐sequencing has broadened perspectives regarding the estimation of the effective population size (Ne) by providing high‐density genomic information. These technologies have expanded data collection and analytical tools in population genetics, increasing understanding of populations with high abundance, such as marine species ...

Estimating effective population size using close‐kin mark–recapture

Methods 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).

Spatial close‐kin mark‐recapture models applied to terrestrial species with continuous natal dispersal

Methods in Ecology and Evolution
Close‐kin mark–recapture (CKMR) methods use information on genetic relatedness among individuals to estimate demographic parameters. An individual's genotype can be considered a ‘recapture’ of each of its parent's genotype, and the frequency of kin‐pair ...

Genomic Insights Into the Origin, Decline and Recovery of the Once Critically Endangered Iberian Lynx. [PDF]

Mol Ecol
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.

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

Environmetrics
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.

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

Feasibility of a Close-Kin Mark-Recapture for Stock Assessment of Indian Ocean Swordfish (Xiphias gladius)

Fishes
The Indian Ocean Tuna Commission (IOTC) manages swordfish, Xiphias gladius, a species of high economic importance in the Indian Ocean. Current stock assessments rely on catch per unit effort indices, which can be biased, complicating reliable abundance ...

Genes, fish and fisheries: translating science into policy

Journal of Fish Biology, EarlyView.
Abstract The 2024 Annual Symposium of the Fisheries Society of the British Isles reviewed the burgeoning impact of ‘omics’ technologies on fish ecology, management and forecasting. As with life sciences more generally, major advances in speed, cost‐effectiveness and breadth of applications in ‘omics’ has had profound societal and environmental impacts.
