Shuitu Baochi Xuebao, 2021 团聚体是土壤的基本结构单位，其稳定性是评价土壤质量的重要指标。以南亚热带地区不同母质（石灰岩、第四纪红黏土、砂页岩）发育的土壤作为研究对象，采用湿筛法和LB法测定不同母质发育土壤团聚体稳定性特征。结果表明：（1）随着土层深度的增加，土壤容重呈上升趋势，而孔隙度、有机质和游离氧化铁含量呈下降趋势。砂页岩母质发育的土壤有机质含量最高，为22.44~42.97 g/kg。石灰岩和第四纪红黏土母质发育的土壤以黏粒（40.93%，42.51%）和粉粒（41.69%，42.31%）为主 ...

Wildlife Letters, Volume 4, Issue 1, Page 23-31, March 2026.American badgers, a medium‐sized carnivore occurring in much of North America, are important predators in prairie landscapes though our understanding of their habitat use requirements in these areas is unclear. We used a multi‐scale approach to understand American badger habitat use at both local and landscape scales.

World 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,
