Climate‐Modulated Particle Toxicity: Acute Exposure to an Environmentally Informed Microplastic Mixture Induces Sex‐Dependent Systemic Reorganization in Swiss Mice

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Microplastic (MP) pollution is widely recognized as an emerging environmental threat. Yet, most studies still rely on controlled experimental conditions that poorly reflect environmental complexity, potentially underestimating risks under realistic scenarios, particularly during short‐term exposures. Here, we tested whether acute oral exposure

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
