Extending the Latent Multinomial Model with Complex Error Processes and Dynamic Markov Bases [PDF]

, 2015
The latent multinomial model (LMM) model of Link et al. (2010) provided a general framework for modelling mark-recapture data with potential errors in identification. Key to this approach was a Markov chain Monte Carlo (MCMC) scheme for sampling possible

Computationally efficient Bayesian capture–mark–recapture models with transients, applied to survival of hand‐reared African Penguins

Methods in Ecology and Evolution, EarlyView.
Abstract Mark–recapture models are the primary framework for estimating demographic parameters in wild organisms. Complex life histories and sampling processes demand complex model formulations, yet these are vulnerable to errors in implementation and unanticipated biases.

Monitoring African Megafauna in an Anthropogenic Landscape: A 15‐Year Case Study of the Vulnerable West African Giraffe

Animal Conservation, EarlyView.
We used pattern recognition software to correct misidentifications in a 15‐year photographic database of the last, vulnerable West African giraffe population in Niger. After revealing substantial methodological errors that had inflated population estimates by nearly 19%, we corrected individual encounter histories and applied capture‐mark‐recapture ...

Age‐specific survival of reintroduced swift fox in Badlands National Park and surrounding lands

Wildlife Society Bulletin, 2016
In 2003, a reintroduction program was initiated at Badlands National Park (BNP), South Dakota, USA, with swift foxes (Vulpes velox) translocated from Colorado and Wyoming, USA, as part of a restoration effort to recover declining swift fox populations ...

Survival and abundance of polar bears in Alaska’s Beaufort Sea, 2001–2016

Ecology and Evolution, 2021
The Arctic Ocean is undergoing rapid transformation toward a seasonally ice‐free ecosystem. As ice‐adapted apex predators, polar bears (Ursus maritimus) are challenged to cope with ongoing habitat degradation and changes in their prey base driven by food‐

Lake sturgeon (Acipenser fulvescens) growth and longevity estimated from adult capture–mark–recapture data

Journal of Fish Biology, EarlyView.
Abstract Effective fishery management policy depends on accurate life‐history data, particularly for harvested species. Longevity is a core life‐history trait that is directly related to annual survival and lifetime reproductive potential, but fish longevity is generally not well documented, particularly for long‐lived species.

Estimating long-term trends in abundance and survival for nesting flatback turtles in Kakadu National Park, Australia

Endangered Species Research, 2017
Flatback turtles Natator depressus are endemic to Australia and Papua New Guineaís tropical oceans and, although the species has an extensive distribution around northern Australia, there are few published long-term abundance trends of nesting ...

Age‐specific, population‐level pedigree of wild black bears provides insights into reproduction, paternity, and maternal effects on offspring apparent survival

Ecology and Evolution, 2022
Wildlife pedigrees provide insights into ecological and evolutionary processes. DNA obtained from noninvasively collected hair is often used to determine individual identities for pedigrees and other genetic analyses.
