Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Conservation Biology, EarlyView.Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

Zhejiang Daxue xuebao. Lixue ban, 2022 基于浙江省1980—2020年8期土地利用数据，分析了浙江省不同时期水域系统时空格局、水面率、转换趋势、景观格局等特征，揭示了水域系统面积变化的驱动因素。结果表明：（1）浙江省水域面积总体呈增加趋势，河流、滩地面积缩减，湖泊、水库坑塘、滩涂面积增加。水域系统转移集中于河流、湖泊和沿海一侧。（2）浙江省水域景观格局MPS、NP、LST、FRA、CCONTAG指数上升，PD、ED、LPI、COHESION、AI指数下降，突出反映了水域景观破碎化、离散化、复杂化。（3）不同地级市水域系统面积存在差异 ...

Dizhen xuebao, 2021 为分析场地的横向不均匀性对水平竖向谱比HVSR曲线产生的显著影响，本文基于Sánchez-Sesma等提出的扩散场方法，通过计算总波场格林函数虚部对二维沉积地形上的HVSR曲线进行模拟。格林函数虚部则通过刚度矩阵和平面内斜线格林函数采用间接边界元方法进行求解。对二维沉积地形和相应的一维层状半空间的HVSR曲线进行了参数分析，着重讨论了沉积地形的形状、相对计算点位置等因素对HVSR曲线的影响规律。结果表明：沉积地形内外材料阻抗比对HVSR曲线的影响最为显著 ...

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years
Conservation Biology, EarlyView.Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal
Conservation Biology, EarlyView.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 ...

Justice in coexistence: Pastoralism and large carnivores on the Qinghai‐Tibet Plateau
People and Nature, Volume 8, Issue 7, Page 2186-2199, July 2026.Abstract The conflict between livestock husbandry and large carnivore conservation presents significant challenges in grassland ecosystems worldwide. Achieving sustainable coexistence among herders, livestock and large carnivores requires reconciling diverse perspectives and interests through equitable, inclusive and fair processes that address both ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Multicomponent transition metal oxides (TMOs) incorporating rare‐earth (RE) elements have emerged as promising materials for the oxygen evolution reaction (OER). However, knowledge of how to regulate the structure of TMO‐based nanomaterials through RE incorporation to enhance catalytic performance remains limited.

Functional Ecology, Volume 40, Issue 4, Page 983-1000, April 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.
