Subspecies taxonomy reflects social and geographic patterns of taxonomic effort in tetrapods
Conservation Biology, EarlyView.Abstract Subspecies have been used in conservation biology to account for intraspecific patterns in genetic diversity, which is crucial to long‐term population viability. Although over 3200 subspecies are currently assessed by the International Union for Conservation of Nature Red List, their biological relevance remains controversial.

, 2011 高校空间分布是一定历史时期区域高等教育资源配置稳定性的表现,对高等教育的发展有重要影响。当前,我国高校空间分布在总体上呈现均匀分布与随机分布相伴、集中分布与分散分布并存,以及条状分布与块状分布相结合等特征。对高校空间分布特征进行分析和探讨,可为高等教育改革与发展提供一定的理论借鉴。湖南省教育厅资助科研项目“高等学校布局结构变革与调整研究”的成果 ...

Wildlife Letters, Volume 4, Issue 3, Page 107-117, September 2026.Human‐caused leopard deaths in Sri Lanka averaged 9.65 ± 4.5 records year−1 over 17 years (2008–2024; n = 164), with records highly clustered in the central highland mosaic ecosystem. Mortality was dominated by adult males and driven primarily by snaring in plantation landscapes, and indicating an increase approximately 0.7–0.8 deaths per year.

Functional Ecology, Volume 40, Issue 9, Page 2726-2736, September 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The commercialization of lithium–sulfur batteries (Li–S batteries) has been hindered by the shuttle effect of lithium polysulfides (LiPSs) and sluggish redox kinetics. In this study, we constructed a three‐dimensional hollow conductive network host material for sulfur with synergistic enhancement effects.

Shuitu Baochi Xuebao, 2003 香港地区每年均有一定数量的滑坡灾害发生,诱发滑坡灾害的主要因子是强降水,即暴雨.暴雨过程中,降水强度的时空分布存在一定差异性,这种降水强度的时空与滑坡灾害的时空分布存在一定的联系.以香港地区1992年5月8日暴雨为例,以30 min为时间间隔,分析了暴雨中心时空变动与滑坡事件时空分布及出现频率之间的关系,发现空间上滑坡均出现在暴雨中心或暴雨中心的边沿地区;时间上滑坡事件出现在暴雨中心出现或上一阶段时间内;并且降水的强度与滑坡的出现频率也有一定关系.

基于有限元方法的35 kV干式空心并联电抗器匝间电场分布研究
Gaoya dianqi, 2018 深入开展35 k V干式空心电抗器匝间电场分布研究,对35 k V干式空心电抗器匝间放电故障分析和提高35 k V干式空心电抗器的可靠运行具有重要意义。为此,文中基于有限元仿真计算开展了35 k V干式空心电抗器匝间电场分布研究。研究结果表明:35 k V干式空心电抗器外层支路匝间电场强度大于内层支路的匝间电场强度,且由于35 k V干式空心电抗器电磁场分布的特殊性导致了每层支路中端部的匝间电场强度小于中间部分的匝间电场强度;10 k Hz下的匝间电压比与50 Hz下的匝间电压比近似相同。

Flexible, Robust Transparent Conductive Films With Excellent Electromagnetic Shielding Properties
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Transparent conductive films (TCFs) are indispensable components for next‐generation wearable electronics, intelligent robots, and electromagnetic interference (EMI) shielding devices. However, the fabrication of conventional random metallic mesh suffers from an inherent trade‐off between “randomness and controllability”.

Shuitu Baochi Xuebao, 2016 采用电磁感应(EMI)、地统计学半变异函数和Kriging空间插值方法研究小泊湖退化湿地土壤盐分的空间分布。结果表明：土壤表观电导率(ECa)和0—40 cm土壤盐分呈线性显著正相关，说明在小泊湖湿地土壤表观电导率的变化可以用以反映土壤盐分含量的变化；半变异函数分析表明，土壤盐分具有强空间相关性[C/(C0+C)＞0.5]，其空间分布主要是由结构性因素引起的；高斯模型(R2=0.98)插值土壤盐分表明，土壤盐分空间分布与退化湿地的空间分布表现出明显的一致性，放牧活动强烈的退化区域土壤盐分相对较高 ...

Collaboration in Cross‐Jurisdictional Water Quality Governance: A Novel Framework and Case Study
World Water Policy, Volume 12, Issue 3, August 2026.ABSTRACT Collaborative governance is often employed to address the inherent complexity of surface water quality governance and provides a structure for cooperation across federal, tribal, state, and local boundaries. However, although guidance exists for assessing specific dimensions of collaborative governance, tools to comprehensively evaluate the ...
