Estimation of Parental Abundance Using Hierarchical Bayesian Modeling With Data Augmentation

Ecology and Evolution
Pedigree‐based estimation methods 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.

Estimating the Abundance of Widely Distributed Primates

American Journal of Primatology
ABSTRACT Monitoring the abundance of widely distributed animals poses many logistic challenges, and is rarely done because the wide distribution generally suggests a lack of conservation concern and thus funding. However, as there are increasing concerns about the conservation status of some widely distributed primates, evidence based

Assessing the suitability of a one‐time sampling event for close‐kin mark‐recapture: A caribou case study

Ecology and Evolution
Abundance estimation is frequently an objective of conservation and monitoring initiatives for threatened and other managed populations. While abundance estimation via capture–mark–recapture or spatially explicit capture–recapture is now common, such ...
