Multiple global change factors alter the scaling of nitrogen to phosphorus in alpine plants
Functional Ecology, Volume 39, Issue 8, Page 2044-2055, August 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometry and allometry of nitrogen (N) and phosphorus (P) reflect nutrient absorption and dynamic allocation by plants, and can be regulated by global change factors (e.g. nitrogen enrichment, climate warming and altered precipitation). Yet, how multiple global

New Phytologist, Volume 247, Issue 3, Page 1117-1128, August 2025.Summary Environmental changes and their effects are among the most pressing topics of today's ecological research. Shrublands, although widespread across the globe, remain understudied in this respect. We conducted a global meta‐analysis of 81 shrubland sites subjected to experimental warming, shifts in precipitation (e.g.

Studies on Propagation and Diffusion Properties of Sonneratiaapetala in Latitude Gradient [PDF]
, 2014 摘要 无瓣海桑是1985年从孟加拉国引入中国的，由于生长快速，目前已成为红树林恢复造林的首选树种，在中国东南沿海各省广泛种植。基于对无瓣海桑的潜在入侵力的担忧，本研究在我国东南沿海各红树林区，选择海南三亚、海口，广东雷州、湛江、电白、深圳和汕头，福建漳浦、厦门和泉港等12个不同纬度的样点，对无瓣海桑的繁殖和漂浮特性进行研究，探讨入侵潜力在纬度上的差异。研究结果表明： 1．同龄无瓣海桑繁殖体数量与纬度呈极显著负相关关系（pAbstract Sonneratiaapetala, a popular ...

Shuitu Baochi Xuebao, 2021 通过室内土柱模拟淋洗试验，研究不同水分条件下添加秸秆和生物炭对海南热带水稻土氮淋失的影响。物料添加设对照（CK）、添加生物炭（B）、生物炭+水稻秸秆（BCS）、水稻秸秆（CS）4个处理，培养水分设75%田间持水量（WHC，模拟旱作土壤）和淹水（模拟水田）2个水平。结果表明，生物炭和秸秆添加均可以提高土壤pH，增加土壤有机质、全氮、速效钾和有效磷含量。75%WHC条件下，相比CK，BCS和CS处理显著增加土壤NH4+—N的淋失量，分别增加16.30%和48.56%，B处理无显著差异；CS处理增加土壤NO3-
