Shuitu Baochi Xuebao, 2023 为揭示森林生态系统养分循环和水分循环对氮沉降的响应机制,以滇中高原华山松(Pinus armandii)和云南松(Pinus yunnanensis)为研究对象,开展野外氮添加下凋落叶、枝原位分解研究试验,设置对照、低氮、中氮和高氮共4个处理,利用尼龙网袋法和室内浸泡法,探究凋落叶、枝养分元素残留率、持水量和持水率及吸水速率对氮添加的响应。结果表明:(1)随着分解时间的持续,2种林分凋落叶、枝碳(C)、氮(N)、磷(P)分别呈释放、富集—释放、富集过程,凋落叶C、N、P残留率显著小于凋落枝(p＜0.05)

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity
Conservation Biology, EarlyView.Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).
