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

Contrastive ecoacoustic indices: Large‐scale global soundscape characterization with contrastive inference

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Ecoacoustics mainly aims at monitoring soundscapes by means of non‐invasive protocols. Despite the widespread adoption of machine and deep learning techniques, existing ecoacoustic models predominantly rely on supervised learning and, consequently, face two primary limitations: (1) the necessity of annotated data; and (2) the restriction to ...

Rethinking Spatial Prioritisation for Primate Conservation in an Unprotected Intact Forest Landscape in the Gulf of Guinea

open access: yesAnimal Conservation, EarlyView.
This study highlights the importance of the unprotected Yabassi Key Biodiversity Area, Cameroon, for primate conservation in the Gulf of Guinea biodiversity hotspot. We modelled primate distribution patterns and found that historically overlooked parts of the landscape have high species richness and are critical for some threatened species.
