Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects
Wildlife Biology, EarlyView.Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)

Den attendance by Arctic foxes experiencing 10 years of increasing tourism
Wildlife Biology, EarlyView.Wildlife tourism is a growing industry, and an increasing number of people seek to observe and interact with wild animals in their natural surroundings. In Iceland, the native Arctic fox Vulpes lagopus is widespread and has been under heavy hunting pressure for centuries.

Wildlife Biology, EarlyView.This research paper investigates the efficacy of leading machine learning (ML) models for detecting and identifying ungulate species in African savanna using nadir imagery from unmanned aerial vehicles (UAVs). Traditional aerial counting methods, while widely used, suffer from significant limitations in accuracy and precision, in part due to human ...

Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain
Wildlife Biology, EarlyView.Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

Wildlife Biology, EarlyView.Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Wildlife Biology, EarlyView.Food acquisition is arguably the most important, and among the riskiest behaviours for most mammals. Carcasses are an ephemeral resource for many scavengers, particularly black‐backed jackals Lupulella mesomelas that prey on small mammals. Landscape of fear theory suggests that prey species should reduce their activity in areas of high predator ...

Wildlife Biology, EarlyView.Long‐term captive breeding programs play a critical role in the conservation and reintroduction of endangered species, yet they face persistent challenges related to demographic structure and genetic management. The Przewalski's horse Equus przewalskii, once extinct in the wild, represents a global model for conservation breeding supported by pedigree ...

Wildlife Letters, EarlyView.Human‐caused leopard deaths in Sri Lanka averaged 9.65 ± 4.5 records year−1 over 17 years (2008–2024; n = 164), with records highly clustered in the central highland mosaic ecosystem. Mortality was dominated by adult males and driven primarily by snaring in plantation landscapes, and indicating an increase approximately 0.7–0.8 deaths per year.
