Shuitu Baochi Xuebao, 2019 为探究园林废弃物制成的覆盖垫是否适用于覆盖城市裸露土壤，采取室内试验方法，对不同施胶量（胶黏剂添加质量分别占园林废弃物质量的20%，25%，30%，35%和40%）不同粒径（小粒径0~1 cm，大粒径1~3 cm）10种覆盖垫的抗压性能、透水性能和持水性能进行测试，以期选出合适施胶量合适粒径的覆盖垫。结果表明：随着施胶量的增加，不同覆盖垫的抗压性均显著增强，且泡水前优于泡水后。小粒径覆盖垫在施胶量不高于30%时透水能力相对较好，施胶量高于30%时的透水能力显著变差，渗透系数为1.09~9.35 cm/s。

Rare Metals, EarlyView.ABSTRACT Recently, cobalt/nitrogen co‐doped materials have emerged as heterogeneous catalysts to activate peroxymonosulfate (PMS) and have been applied to advanced oxidation processes for environmental remediation. However, their recyclability and reusability remain major barriers to practical application.

Shuitu Baochi Xuebao, 2019 以青海省大通县安门滩小流域7种造林密度的青海云杉人工林为研究对象，利用浸水法、环刀法测定林下枯落物、草本层及0—60 cm土壤层的持水量，定量评价不同密度的青海云杉人工林水源涵养功能。结果表明：（1）不同造林密度下的林分枯落物最大持水量变化范围为1.97~7.60 m3/hm2，枯落物持水量最大的造林密度为1 725株/hm2，造林密度为2 300株/hm2的枯落物持水量最小；不同造林密度的林下草本层持水量变化范围为1.97~7.17 m3/hm2，林下草本层持水量最大的造林密度为1 575株/hm2。（

Rare Metals, EarlyView.ABSTRACT Photocatalytic hydrogen production from water splitting is a promising strategy for sustainable and clean energy generation. However, the design of low‐cost, highly active photocatalysts remains a critical challenge. In this study, covalent organic frameworks (COFs) were loaded onto the surface of Cd0.9Cu0.1S to fabricate COF/Cd0.9Cu0.1S ...

Shuitu Baochi Xuebao, 2006 对马占相思人工林3个不同年龄阶段（4，7a和11a）的林冠层、林下植被层、枯枝落叶层、林地土壤持水量和渗透性能以及它们随林分年龄的变化规律进行了比较分析。研究结果表明，林分地上部分持水量的大小顺序为11a生（52．86t／hm^2）〉7a生（41．90t／hm^2）〉4a生（25．78t／hm^2），其趋势是随林龄的增大而增加，林地土壤（0～40cm）持水量和渗透性能也有相同的变化趋势；4，7a和11a林分的总持水量即地上部分与林地土壤的持水总量分别为2048．8，2200．3，2313．3t／hm^2，

Conservation Biology, EarlyView.Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

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 ...

A link between increased temperature and avian body condition in a logged tropical forest
Conservation Biology, EarlyView.Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves
Conservation Biology, EarlyView.Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.
