Does Your Species Have Memory? Analysing Capture-Recapture Data with Memory Models. [PDF]
1. We examine memory models for multi-site capture-recapture data. This is an important topic,as animals may exhibit behaviour that is more complex than simple first-order Markov movement between sites, when it is necessary to devise and fit appropriate ...

How does spatial study design influence density estimates from spatial capture-recapture models? [PDF]
When estimating population density from data collected on non-invasive detector arrays, recently developed spatial capture-recapture (SCR) models present an advance over non-spatial models by accounting for individual movement.

Embedding population dynamics in mark-recapture models [PDF]
Mark-recapture methods use repeated captures of individually identifiable animals to provide estimates of properties of populations. Different models allow estimates to be obtained for population size and rates of processes governing population dynamics.

A generalised likelihood framework for partially observed capture-recapture-recovery models [PDF]
We provide a closed form likelihood expression for multi-state mark-recapture-recovery data when the state of an individual may be only partially observed.

Recommendations for photo-identification methods used in capture-recapture models with cetaceans [PDF]
Capture-recapture methods are frequently employed to estimate abundance of cetaceans using photographic techniques and a variety of statistical models. However, there are many unresolved issues regarding the selection and manipulation of images that can ...

Estimating abundance of rare, small mammals: A case study of the Key Largo woodrat (Neotoma floridana smalli) [PDF]
Estimates of animal abundance or density are fundamental quantities in ecology and conservation, but for many species such as rare, small mammals, obtaining robust estimates is problematic.

Estimating fault numbers remaining after testing [PDF]
Testing is an essential component of the software development process, but also one which is exceptionally difficult to manage and control. For example, it is well understood that testing techniques are not guaranteed to detect all faults, but more ...

Face Value: Towards Robust Estimates of Snow Leopard Densities. [PDF]
When densities of large carnivores fall below certain thresholds, dramatic ecological effects can follow, leading to oversimplified ecosystems. Understanding the population status of such species remains a major challenge as they occur in low densities ...

Estimating Wildlife Density as a Function of Environmental Heterogeneity Using Unmarked Data
Recent developments to spatial-capture recapture models have allowed their use on species whose members are not uniquely identifiable from photographs by including individual identity as a latent, unobserved variable in the model.

Best practices for reporting individual identification using camera trap photographs
Camera traps have become a popular sampling tool in ecological studies. This is especially true for studies that estimate population densities through spatial capture-recapture models of species with physical traits allowing individual identification ...
