Intangible drivers of tolerance shape human–elephant coexistence in Southwest China
People and Nature, EarlyView.Abstract Southwest China is home to a small but rapidly expanding population of Asian elephants (Elephas maximus), whose growth has intensified conflicts with people living in shared landscapes. These conflicts result in substantial economic losses and occasional human casualties. This coexistence paradox—where conservation success leads to significant

Wildlife Letters, EarlyView.Asiatic black bears in Russia face conservation threats such as habitat destruction and fragmentation, which exacerbate food shortages caused by crop failures. This study explores an innovative approach to rehabilitating bears that abandon hibernation in mid‐winter due to extreme exhaustion by providing supplemental food near their den sites.

Wildlife Letters, EarlyView.Using a 3‐year, broad‐scale camera‐trap network in western Kansas, we tested whether coyotes and American badgers exhibit spatiotemporal patterns consistent with coordinated hunting. Despite high diel activity overlap, detection‐conditioned co‐detections occurred far less frequently than expected under independence, and short‐term temporal sequencing ...

Haiyang yu huzhao高强度养殖活动显著改变了主要生源要素的分布特征与循环过程，导致养殖水体呈现严重富营养化状态、有害藻华频发，既限制了养殖业的健康发展，又对周围海洋生态环境造成了负面影响。近年来，养殖水体水质调控成为研究热点，基于2023年5~9月份对莱州湾凡纳滨对虾精养池塘水体主要生源要素的现场观测与对比体系研究，揭示了改性粘土对主要生源要素分布特征的影响，结合培养实验，探究了改性粘土对主要生源要素循环的调控作用。结果表明，对虾养殖池塘水体中主要生源要素（碳、氮和磷）含量整体呈现波动上升的变化趋势。喷洒改性粘土24 ...

Wildlife Letters, EarlyView.Many nocturnal animals are difficult to study because they are rarely seen, including nocturnal primates, galagos and pottos, in West Africa. Working with over 600 people in 52 villages in southern Guinea‐Bissau, we found that communities frequently recognized galagos by their red eyeshine and distinctive calls, while pottos were not known.

Wildlife Letters, EarlyView.Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...
