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

Survival and movements of brown‐headed nuthatches after translocation to the Missouri Ozarks

Wildlife Society Bulletin, 2023
The brown‐headed nuthatch (Sitta pusilla) was likely extirpated from Missouri in the early 1900s as a result of habitat loss through extensive logging. Conservation partners including the Missouri Department of Conservation, United States Forest Service,

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

Climatic Variability Threatens Population Growth and Persistence of a Declining Grassland Songbird. [PDF]

Ecol Evol
Determining the factors responsible for population change in threatened populations and the degree to which changing climates might put those populations at risk is one of the most pressing roles of conservation science. We tested whether increasing variability in weather could have driven recent declines in songbird population numbers using detailed ...

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.

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 ...

Seasonal body mass dynamics mediate life‐history trade‐offs in a hibernating mammal

Journal of Animal Ecology, EarlyView.
We tested a suite of ecological hypotheses to explain variation in seasonal body mass dynamics of a fat‐storing mammalian hibernator. We further demonstrated that pre‐hibernation mass gain in ground squirrels mediates an annual allocation trade‐off between current and future reproduction as the squirrels forage and rear young under predation risk ...

Methodological advances [PDF]

, 2004
The study of population dynamics has long depended on methodological progress. Among many striking examples, continuous time models for populations structured in age (Sharpe & Lotka, 1911) were made possible by progress in the mathematics of integral ...
