Open population maximum likelihood spatial capture-recapture [PDF]
, 2019 Funding: Part-funded by UK EPSRC grant EP/K041061/1 (DB); Richard Glennie was funded by the Carnegie Trust.Open population capture‐recapture models are widely used to estimate population demographics and abundance over time.

Trace-contrast models for capture-recapture without capture histories [PDF]
, 2018 This work was funded by the Royal Society of New Zealand through Marsden Grant 14-UOA-155. Ben Stevenson was supported by EPSRC/NERC Grant EP/1000917/1.Capture-recapture studies increasingly rely upon natural tags that allow animals to be identified by ...

Frontiers in Conservation Science, 2022 Reliable estimates of population density and size are crucial to wildlife conservation, particularly in the context of the Endangered Species Act. In the United States, ocelots (Leopardus pardalis pardalis) were listed as endangered in 1982, and to date,

Accommodating False Positives Within Acoustic Spatial Capture–Recapture, with Variable Source Levels, Noisy Bearings and an Inhomogeneous Spatial Density [PDF]
Journal of Agricultural Biological and Environmental Statistics, 2022 Passive acoustic monitoring is a promising method for surveying wildlife populations that are easier to detect acoustically than visually. When animal vocalisations can be uniquely identified on an array of sensors, the potential exists to estimate ...

Study design and mark-recapture estimates of dispersal: A case study with the endangered damselfly Coenagrion mercuriale [PDF]
, 2012 Accurate data on dispersal ability are vital to the understanding of how species are affected by fragmented landscapes. However, three factors may limit the ability of field studies to detect a representative sample of dispersal events: (1) the number of

PLoS ONE, 2015 Capture-recapture studies are frequently used to monitor the status and trends of wildlife populations. Detection histories from individual animals are used to estimate probability of detection and abundance or density.

Journal of Vertebrate Biology, 2022 . As apex predators with a regulating effect on interspecific competitors and prey demographics, monitoring of spotted hyaena (Crocuta crocuta) population trends can provide a reliable indicator of ecosystem health. However, the ability of current survey

Testing the consistency of wildlife data types before combining them: the case of camera traps and telemetry. [PDF]
, 2014 Wildlife data gathered by different monitoring techniques are often combined to estimate animal density. However, methods to check whether different types of data provide consistent information (i.e., can information from one data type be used to predict

A comparison of four different methods to estimate population size of Alpine marmot (Marmota marmota) [PDF]
, 2017 Obtaining reliable information on animal abundance in mountainous landscapes is challenging. Highly heterogeneous habitats tend to reduce detection probabilities, and the three-dimensional, rugged nature of the terrain poses severe limits to the ...
