Integrative Conservation, Volume 5, Issue 3, Page 306-316, September 2026.ABSTRACT In today's rapidly urbanizing world, the survival of wildlife in cities faces significant challenges, and the attitudes of urban residents toward wildlife play a crucial role in their survival. Otters, as top predators in freshwater ecosystems who are highly sensitive to environmental changes, had once gone extinct in Shenzhen—a megacity ...

Functional Ecology, Volume 40, Issue 9, Page 2843-2860, September 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Drylands are mainly structured by both vascular plants and biological soil crusts (biocrusts), the latter often regarded as a self‐organizing component of these ecosystems.

Intangible drivers of tolerance shape human–elephant coexistence in Southwest China
People and Nature, Volume 8, Issue 8, Page 2763-2780, August 2026.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

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Ultrathin, lightweight, and mechanically compliant electromagnetic interference (EMI) shields are increasingly required for high‐frequency electronic devices. However, conventional metallic shields predominantly rely on conductivity‐driven reflection mechanisms, which become ineffective at reduced thickness and may cause severe secondary ...

Gaoya dianqi, 2023 电池储能系统被认为是解决可再生能源的不确定性和不平衡性导致的功率不足和频率波动的有效途径。基于此，文中提出了一种基于电池的荷电状态SOC(state of charge)的电池储能系统混合控制策略。首先，文中将电池的SOC、调频和调峰需求划分为不同的区域，并对调频和调峰提出相应的控制策略，提出SOC自恢复控制策略。之后提出储能的混合控制策略，基于电池储能的SOC，将储能的调频与调峰功能与SOC自恢复策略相结合，实现储能对电力系统的优化。最后通过仿真分析验证该控制策略的合理性与应对可再生能源波动的能力。

Magnetization Dynamics Control for Noise Reduction in Fluxgate Sensors
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Fluxgate sensors are indispensable for the detection of weak magnetic fields. However, their noise performance remains constrained by an incomplete understanding of the interplay between the high‐frequency magnetization dynamics of the core material and the overall sensor behavior.

全球能源互联网面对新型电力系统的低惯量趋势，规模庞大而位置分散的温控负荷在参与电力系统频率响应的同时，能够为电网提供虚拟惯量和一次调频支撑将是提升电网频率安全的新思路。为此，以集中-分布式调控框架下的温控负荷集群为研究对象，首先在详细分解控制层调控中心、协调层聚合商、响应层温控负荷终端三者在辅助调频过程中的采样、计算、控制、执行一系列实时任务的基础上，设计了事件触发与时间触发相结合的温控负荷集群终端异步响应机制，实现温控负荷集群功率遵从综合惯性控制律的效果。随后 ...

Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Knowledge of species distributions is essential for informing policies on nature conservation and restoration. However, updating them on a regular basis and doing so in a harmonized manner at the international level is difficult. The European Bird Census Council integrated national monitoring data covering 5 years to update farmland bird ...

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...
