Advancing Water Security in the Tropical and Subtropical Regions: An Integrative Topic Modeling Approach

open access: yesWorld Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,

Underrepresentation of bats in Africa's protected areas

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Biodiversity is severely threatened globally, with habitat loss and other human pressures accelerating species extinctions. Protected areas (PAs) are a critical conservation tool; however, their effectiveness in safeguarding many taxa, such as bats, remains unclear.

Threshold responses of floating meadow fish communities to floodplain forest cover in the lower Amazon River

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...

Reoccurrence of Dust Storms in South Asia and Their Implications for Vegetation Health 南亚沙尘暴的再次出现及其对植被健康的影响

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 362-380, September 2025.
Occurrences of dust storms and long‐distance movement of dust across landscapes is constantly increasing in south Asia. This dust is expected to have profound impact on vegetation health and sustainability as dust may contribute to nutrient budgets of the forest ecosystems, while it could impart various stresses to the plants.

不同植被覆盖度对紫色土坡面侵蚀过程的影响

open access: yesShuitu Baochi Xuebao, 2017
为研究植被覆盖度对紫色土坡面侵蚀过程的影响,探讨有效控制水土流失的坡面植被临界盖度问题,利用人工模拟降雨试验与室内分析相结合的方法对紫色土坡面侵蚀过程进行分析。结果表明:(1)总体上,紫色土坡面产流量随植被覆盖度的增大而减小,二者之间呈现线性负相关,但是植被覆盖度在25%以下,径流量变化不明显,植被覆盖度达75%时,径流量处于较低的稳定值,明显低于植被覆盖度0%,25%,50%;(2)坡面侵蚀泥沙量随植被覆盖度的增加而减少,二者呈现二次项相关(R2=0.99),植被覆盖度25%以下对坡面减沙起到重要作用,
