Use of species’ responses to cryptic anthropogenic disturbances for monitoring biodiversity outcomes in tropical forests

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
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.

干热河谷不同引进草种水土保持效果比较

open access: yesShuitu Baochi Xuebao, 2008
对3种引进草种的生物量、枯落物量、土壤的容重、孔隙度、自然含水量、毛管持水量、饱和含水量、机械组成、有机质含量、渗透性能和抗蚀能力等进行了测定和分析。结果表明,3种引进草种的水土保持效果依次为纳罗克非洲狗尾草>威提特东非狼尾草>沙弗雷肯尼亚白三叶草,纳罗克非洲狗尾草的持水能力和土壤改良性能最好,是水土保持效果最佳的牧草,可以推广种植,其次是威提特东非狼尾草。

The Long-term Variations and Influencing Factors of Soil Saturated Hydraulic Conductivity in Terraces on the Loess Plateau [PDF]

open access: yes
[Objective] The long-term variations of soil saturated hydraulic conductivity (Ks) and its primary controlling factors in terraces on the Loess Plateau were explored. [Methods] Terraces were selected for three land use types, i.e.

Developments and applications of terrestrial biosphere model [PDF]

open access: yes, 2020
Exchanges of energy and matter between terrestrial biosphere and atmosphere and hydrosphere create critical feedbacks to Earth’s climates. To quantify how terrestrial ecosystems respond and feedback to global changes, terrestrial biosphere model (TBM ...

Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
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.

密度调控对华北落叶松人工林枯落物水文特征的影响

open access: yesShuitu Baochi Xuebao, 2016
为探究密度调控措施对华北落叶松(Larix principis-rupprechtii Mayr)人工林枯落物水文效应的影响,以山西太岳山好地方林场35 a生华北落叶松(principis-rupprechtii L.)人工林为研究对象,采用样地调查和室内浸泡法分析了不同密度调控处理下未分解层和半分解层枯落物储量、枯落物持水特征、枯落物持水量和持水速率及其与浸水时间的关系。结果表明:(1)4种密度调控处理枯落物储量由大到小依次为:轻度密度调控处理(LT)>中度密度调控处理(MT)>重度密度调控处理(HT)

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.

open access: yesNew Phytologist, Volume 250, Issue 2, Page 1231-1247, April 2026.
Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

黄土高原农田水量平衡研究

open access: yesShuitu Baochi Xuebao, 1995
黄土高原由北向南顺序分布有沙壤带、轻壤带、中壤带和重壤带;2m土层最大持水容量约相当于各自所处地区的年降水量;2m土层有效持水容量约相当于各自作物耗水量的70%以上。

关帝山不同林分结构华北落叶松林枯落物水文效应

open access: yesShuitu Baochi Xuebao, 2021
为研究北方山区典型人工林水源涵养效应和更新状况,选取吕梁山脉落叶松纯林为研究对象,采用室内浸水法测定不同林分密度下枯落物的持水性能,用RDA冗余度分析法探究林分结构对枯落物厚度和拦蓄功能的相关关系。结果表明:(1)不同密度华北落叶松样地的枯落物厚度为0.84~4.50 cm,蓄积量范围为9.64~24.14 t/hm2,350株/hm2样地蓄积量最大,200株/hm2样地最小。(2)样地最大持水量范围为27.12~62.07 t/hm2,500株/hm2样地持水量最大,150株/hm2样地最小 ...
