Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain

open access: yesWildlife 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 ...

Assessing the accuracy of field‐based versus laboratory methods for determining the age of roe deer

open access: yesWildlife Biology, EarlyView.
Accurate age determination in roe deer Capreolus capreolus is essential for selective harvesting and informed population management, yet field‐based methods widely used by hunters remain imprecise. This study compared field‐based and laboratory age determination methods in 204 harvested roe deer, categorized by sex and habitat type (forest versus open ...

Availability bias and responsive movement during ground‐based wildlife surveys revealed by concurrent thermal drone surveys

open access: yesWildlife Biology, EarlyView.
Methods to estimate abundance from unmarked populations of animals are widely used because of their efficiency and presumed accuracy. These methods account for imperfect detection by comparing observed data against the assumed distribution of the entire population.

Jaguar Densities and Land Cover Change in a Multi‐Use Landscape: A 10‐Year Comparison in the Colombian Llanos 美洲豹种群密度与复合用地景观下的土地覆被变化:哥伦比亚亚诺斯地区10年比较研究

open access: yesWildlife Letters, EarlyView.
We used spatially explicit capture‐recapture to estimate jaguar densities in a private reserve in the Colombian Llanos and quantified land cover change in and around the reserve from 2014 to 2024. Densities increased 22% since 2014, while disturbed land cover increased by 39%–54% around the reserve depending on buffer distance. Our study indicates that

Spatiotemporal mapping the usable space of free‐roaming equids across the western United States

open access: yesWildlife Society Bulletin, EarlyView.
Identification of the inter‐decadal (2010‐2011) enhancement‐degradation gradients in the usable space for wild equid Herd Management Areas in the Great Basin, USA. Abstract Management of feral equids in the American West is hindered by the lack of a formal habitat map and monitoring system.
