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

Annual survival in a dynamic species: pronghorn survival patterns across their northern range

Wildlife Biology, EarlyView.
Quantifying variation in demographic patterns, such as survival and recruitment, is critical for understanding population dynamics and informing evidence‐based and adaptive wildlife management. In this study, we leverage an extensive dataset from over 1000 GPS collared pronghorn Antilocapra americana to provide the first large‐scale evaluation of ...

When is a parasite not a parasite? Effects of larval tick burdens on white-footed mouse survival [PDF]

, 2014
Many animal species can carry considerable burdens of ectoparasites: parasites living on the outside of a host's body. Ectoparasite infestation can decrease host survival, but the magnitude and even direction of survival effects can vary depending on the

Fate of orphans of Canada geese harvested by hunters in Connecticut, USA, depends upon which month the parents were killed

Wildlife Biology, EarlyView.
Little is known about what happens to juvenile birds after one or both of their parents are harvested by hunters during the post‐fledging dependency period. Here, we compare the fate of juvenile Canada geese Branta canadensis that lost ≥ 1 parent to hunters (orphans) during this period to other juveniles that retained both parents (non‐orphans). For 25

Covariantes continuas individuales dependientes del tiempo y el modelo de Cormack–Jolly–Seber [PDF]

, 2004
The Cormack–Jolly–Seber model provides the basic framework for analyzing the survival of animals in open populations using capture–recapture data. Extensions of this model have already been developed that allow the survival and capture probabilities to ...

State space and movement specification in open population spatial capture-recapture models. [PDF]

, 2018
With continued global changes, such as climate change, biodiversity loss, and habitat fragmentation, the need for assessment of long-term population dynamics and population monitoring of threatened species is growing.

Drone‐based radiotelemetry and imagery systems provide an advantage over traditional techniques for estimating survival of dependent juveniles

Wildlife Society Bulletin, EarlyView.
We used drone‐based radiotelemetry and multispectral imagery to estimate detection and survival probabilities of blue‐winged teal broods in Saskatchewan, Canada. Weekly brood survival probabilities, estimated via Cormack‐Jolly‐Seber models, increased with age and were comparable between drone methods.

Use of capture–recapture models to evaluate abundance and dynamics of a stocked Muskellunge population

Aquaculture, Fish and Fisheries
To evaluate the success of a stocking program in Fox Lake, Minnesota, adult (≥76 cm total length) Muskellunge were captured with large nearshore trap nets and individually marked with passive integrated transponder tags during the 2011–2013 and 2015–2017

Cryptic disease-induced mortality may cause host extinction in an apparently stable host- parasite system [PDF]

, 2017
The decline of wildlife populations due to emerging infectious disease often shows a common pattern: the parasite invades a naive host population, producing epidemic disease and a population decline, sometimes with extirpation.

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.
