Conservation Biology, EarlyView.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

Effects of landscape fragmentation on floodplain fishes as revealed by species–habitat networks
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.

Gaoya dianqi, 2021 近年来高压电缆缓冲层故障频发,可能由波纹护套与缓冲层空气间隙局部电场畸变引起,现有电场仿真研究缺乏对波纹护套压纹深度、节距以及缓冲层阻抗的考虑。文中基于麦克斯韦方程建立了考虑电缆波纹金属护套实际几何结构的数值仿真模型和平滑金属护套电缆的电路计算模型,定量分析了110 kV电缆缓冲层材料电导率和介电常数以及波纹金属护套几何结构对空气间隙电势与电场分布的影响。研究表明,当缓冲层材料电导率在10-6～10-9S/m时,空气间隙电势主要受缓冲层材料电导率的影响;当缓冲层材料电导率小于10-9S/m时 ...
