, 2014 Open source geographic information systems (GIS) tools are maturing to the point of being viable for widespread use. QGIS is a desktop GIS system that is cross-platform, free, extensible and interoperates well with other GIS tools. Data services that support desktop GIS software packages are increasingly supporting QGIS, and ideas for promoting open ...

Are human‐altered landscapes reshaping carnivore niche spaces in the Trans‐Himalaya?
Wildlife Biology, EarlyView.Understanding carnivore interactions under growing human pressures is crucial for conservation. We examined spatial and temporal niche structuring among snow leopards Panthera uncia, Himalayan wolves Canis lupus chanco, and red foxes Vulpes vulpes; while also incorporating free‐ranging dogs Canis lupus familiaris as a human‐subsidized mesopredator ...

Wildlife Biology, EarlyView.Urban green spaces experience a mix of natural and anthropogenic noises, which could disrupt the vocal communication of several species. This study investigated how such complex soundscapes affect the occurrence of Anaxipha pallidula, which communicates through calls, focusing on both sound level and quality.

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.Robust monitoring of wildlife populations to guide interventions is fundamental to conservation and wildlife management. Understanding how landscape characteristics are influencing predator population dynamics is often vital to inform recovery strategies, management, and policy. The pine marten Martes martes is recovering in the UK; however, population

Wildlife Biology, EarlyView.Limited information on moose calving behaviour, including parturition timing, cow‐calf interactions, and pre‐ and post‐partum movement patterns hinder our ability to define calving phenology and habitat use. GPS‐collars were deployed on 89 female moose over five years, including eight collars equipped with animal‐borne video and environmental data ...
