Estimating large carnivore populations in an arid fenced reserve using spatial capture–recapture modelling

Wildlife Biology, EarlyView.
In fenced protected areas where large carnivore populations persist or have been restored through reintroduction, population monitoring is essential to inform management. Robust density estimates are particularly important given the strong influence of large carnivores on ecosystem processes, yet such data remain scarce for arid systems where ...

Estimating crippling loss from hunting with multistate models: a case study on northern bobwhites

Wildlife Biology, EarlyView.
Hunting as a recreational pursuit provides an important ecosystem service worldwide. Harvest management plays a vital role in regulating wildlife take to ensure long‐term population sustainability and meet value‐based objectives (e.g. hunter satisfaction). However, managers rarely have complete control or observability of harvest mortality.

Detecting changes in distribution and abundance using harvest data in two sympatric bear species in Southeast Alaska

Wildlife Biology, EarlyView.
Monitoring wildlife populations in remote landscapes is challenging due to the difficulties of conducting field surveys. However, harvest data, which are routinely collected by management agencies, offer valuable insights into population trends. Brown bear Ursus arctosand American black bear U.

Seasonal variation in faecal glucocorticoid metabolite concentrations of two dominant southern African murids (Lemniscomys rosalia and Mastomys coucha) across variously transformed landscapes

Wildlife Biology, EarlyView.
Global landscape transformations are a result of a growing human population and the subsequent increased use of natural habitats. Local species extinctions across various transformed landscapes emphasise the importance of monitoring wildlife responses to anthropogenic activities.

A proof of concept for linking individual identity to camera traps

Wildlife Biology, EarlyView.
Small mammal movements are difficult to monitor, both visually and with remote tracking devices, due to the animals' small body size and elusive behavior. Cameras deployed at fixed locations can provide continuous, non‐invasive records in natural habitats, yet camera‐derived indices remain sparsely validated and generally do not allow inference at the ...
