Wildlife Letters, EarlyView.Although once abundant across its range, gray foxes (Urocyon cinereoargenteus) are purportedly declining. While range maps indicate that gray fox potentially occur throughout the central United States, contemporary distribution maps are needed. We developed a Habitat Suitability Model for six states, leveraging gray fox presence data in an ensemble ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Methods in Ecology and Evolution, EarlyView.Abstract Molecular identification of insect food webs can accurately reveal complex trophic interactions and serve as a foundation for understanding ecosystem functioning and advancing biodiversity conservation. This process typically involves DNA library construction, high‐throughput sequencing and subsequent steps, including data assembly, annotation,

Dianci bileiqi, 2012 配电网保护间隙在提高线路跳闸重合率和防止架空绝缘导线雷击断线上,取得了较为显著的效果。但在实验中发现相对于避雷器动作时间,保护间隙动作时间和绝缘子动作时间相差不多。从保护间隙和避雷器动作时间不同出发,在分析保护间隙保护距离时考虑了保护间隙闪络时间对保护间隙保护距离的影响。先通过实验确定绝缘子和保护间隙的伏秒特性曲线,然后利用相交法计算出不同等级雷电过电压下保护间隙和绝缘子动作时间,最后根据保护间隙和绝缘子的动作时间差和雷电波在线路上传播的速度计算出不同等级雷电过电压下保护间隙的保护距离 ...

When and why to give shorebirds a head start
Conservation Biology, EarlyView.Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

Effects of parachute science on local research capacity 降落伞科学对当地研究能力的影响
Conservation Biology, EarlyView.Abstract Strengthening research capacity is essential to address the global biodiversity crisis. Yet, parachute science often undermines this goal, and its prevalence, costs, and benefits are unclear. We analyzed 13,502 publications on primate research that we extracted from Scopus (1960–2022) to evaluate the effects of parachute science on local ...

Guangtongxin yanjiu, 2017 为解决原有基于G.8132协议的Wrapping保护机制下的环网保护标签维护管理复杂的难题,提出了一种改进的基于Wrapping保护机制的环网保护方案,详细论述了环网保护业务通道的建立与倒换机制,介绍了相关功能模块的架构,并且测试验证了保护倒换时间。该环网保护方案的保护倒换时间足以满足50ms的工程应用要求,因此可为PTN（分组传送网）承载业务提供有效的网络级保护。

Conservation Biology, EarlyView.Abstract Prioritization in conservation is crucial for the development of efficient and effective decision‐making policies. For many decades, the importance of some species and their habitats has been assessed and applied in conservation legislation, but bats and their diurnal roosts have ofbeen overlooked.

The collective application of shorebird tracking data to conservation
Conservation Biology, EarlyView.Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership
