Effects of calcium depletion caused by acid deposition on several forest tree species in southern China [PDF]
, 2012 随着经济的高速发展，SO2和NOx排放急剧增加，酸沉降问题日益严重，并且在将来很长一段时间内都是我国难以回避的重要环境问题。 在北美和欧洲的许多长期观测研究认为酸雨导致森林生态系统营养元素大量流失，特别是钙（Ca）的流失是酸雨导致森林衰退的一个重要的原因。但由于中国酸沉降具有高Ca2+含量的特点，沉降通量较欧美地区高出几倍到几十倍，因此目前对中国森林生态系统中Ca流失所带来的影响及危害还研究的不多。 本研究项目通过野外观测和室内模拟控制实验，较为系统的研究了中国主要的森林植物物种在酸沉降下的响应 ...

Combining camera trap surveys and IUCN range maps to improve knowledge of species distributions
Conservation Biology, Volume 38, Issue 3, June 2024.Abstract Reliable maps of species distributions are fundamental for biodiversity research and conservation. The International Union for Conservation of Nature (IUCN) range maps are widely recognized as authoritative representations of species’ geographic limits, yet they might not always align with actual occurrence data. In recent area of habitat (AOH)

Integrative Conservation, Volume 3, Issue 1, Page 22-35, March 2024.Rubber plantations that are larger in size and remotely located have a higher probability of being linked to forest loss and degradation. The global rubber price can act as a significant driver of both deforestation and degradation. Identifying high‐risk plantations and mitigating associated threats could help curb future forest loss due to rubber ...
