Martin, J., Royle, J. A., Mackenzie, D. I., Edwards, H. H., Kéry, M., & Gardner, B. (2011, April 26). Methods in Ecology and Evolution.

By: J. Martin *, J. Royle *, D. Mackenzie *, H. Edwards*, M. Kéry * & B. Gardner n

author keywords: beta-binomial distribution; binomial mixture; correlated Bernoulli outcomes; correlated behaviour; manatees; truncated Poisson distribution
topics (OpenAlex): Marine animal studies overview; Fish Ecology and Management Studies; Wildlife Ecology and Conservation
TL;DR: This work has shown that correlated behaviour, affecting the non‐independence of individual detections, may also be relevant in other systems (e.g. correlated patterns of singing in birds and amphibians). (via Semantic Scholar)

Comparison of five modelling techniques to predict the spatial distribution and abundance of seabirds

Oppel, S., Meirinho, A., Ramírez, I., Gardner, B., O’Connell, A. F., Miller, P. I., & Louzao, M. (2011, December 31). Biological Conservation.

By: S. Oppel *, A. Meirinho*, I. Ramírez *, B. Gardner n, A. O’Connell *, P. Miller *, M. Louzao *

author keywords: Species distribution model; Machine learning; Marine protected area; Important bird area (IBA); Shearwater; Portugal
topics (OpenAlex): Wildlife Ecology and Conservation; Species Distribution and Climate Change; Avian ecology and behavior
TL;DR: This paper advocates the use of ensemble modelling that combines the output of several methods to predict the spatial distribution of seabirds, and uses these predictions to target separate surveys assessing the abundance of seABirds in areas of regular use. (via Semantic Scholar)

Improving density estimates for elusive carnivores: Accounting for sex-specific detection and movements using spatial capture–recapture models for jaguars in central Brazil

Sollmann, R., Furtado, M. M., Gardner, B., Hofer, H., Jácomo, A. T. A., Tôrres, N. M., & Silveira, L. (2011, January 24). Biological Conservation.

By: R. Sollmann *, M. Furtado *, B. Gardner n, H. Hofer *, A. Jácomo, N. Tôrres *, L. Silveira

author keywords: Bayesian analysis; Camera trapping; Cerrado; Panthera onca; Sex-specific movements
topics (OpenAlex): Wildlife Ecology and Conservation; Primate Behavior and Ecology; Wildlife-Road Interactions and Conservation
TL;DR: To estimate jaguar density in Emas National Park in the central Brazilian Cerrado grassland, an ecological hotspot of international importance, spatially explicit sex-specific capture–recapture models were used and the spatial model is preferable because it explicitly considers animal movements and allows incorporating site-specific and individual covariates.
