Using Harvest Data to Assess Factors Influencing Regional Population Declines of Muskrats (Ondatra zibethicus) 利用捕获数据评估影响麝鼠 (Ondatra zibethicus) 区域种群数量下降的相关因素

Wildlife Letters, EarlyView.
Reported annual per‐capita harvest of muskrats (PCHM) decreased as wetland complexity (total number of wetland patches) decreased in 13 state and federal wetland areas in the Midwest, USA. Our results support the hypothesis that regional‐scale declines in the abundance of muskrats are likely associated with the losses to wetland habitats throughout the

Updates on Breeding Success and Conservation Challenges for White‐Rumped Vulture (Gyps bengalensis) in Rampur Valley, Nepal 尼泊尔兰普尔山谷白腰兀鹫繁殖成功研究进展及其保护挑战

Wildlife Letters, EarlyView.
This study investigates the breeding success of the critically endangered White‐rumped Vulture in Khaireni Community Forest, and examines local knowledge and perceptions toward its conservation. We found that 71% of active nests were successful, with breeding success significantly influenced by the proximity to carcass deposition sites.

Detection‐Dog‐Guided Camera Placement Increases Efficiency of Surveys for Long‐Tailed Weasels (Neogale frenata) 利用探测犬引导布设相机可提升长尾鼬调查效率

Wildlife Letters, EarlyView.
By comparing widespread surveys with randomly placed cameras to a protocol pairing detection dogs with cameras, we found that the detection‐dog‐guided camera survey had approximately 33 times greater detections with fewer camera nights and reduced survey costs. We recommend using detection dogs to identify areas to focus camera trapping. ABSTRACT Multi‐

Elevated nitrogen deposition protects an invasive plant from herbivory through altering leaf volatile‐mediated tritrophic interactions

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Atmospheric nitrogen deposition disrupts plant–herbivore interactions, but its impact on leaf volatile organic compounds (VOCs)‐mediated multi‐trophic herbivore resistance remains unclear within the context of plant invasion. In this study, we initially investigated the
