, 2019 农业生物多样性是指直接或间接用于粮食和农业的动物、植物和微生物的多样性和变异性,包括作物、家畜、林业和渔业等。它位于整个农业系统的底层,是农业生产信息化的重要内容,也是国家战略资源和国家安全的重要基础。国内外相关组织机构和项目积累了很多的资源和建设经验,但是仍然存在资源零散分布、缺乏顶层设计、元数据标准规范应用不足、平台之间的数据交互不够、数据的快速实时响应比较困难、高端农业智库及其资源平台建设薄弱等问题。为了更好地推动我国农业生物多样性大数据平台的研究和开发工作,本文着重从科学数据平台（基础数据平台 ...

Shuitu Baochi Xuebao, 2021 伴随气候变化下亚热带地区米槠天然林净初级生产力变化，凋落物以及植物根系输入亦会发生改变，这将显著影响土壤微生物群落。于2019年7月在设置7年的米槠天然林植物残体添加和去除试验（the detritus input and removal treatments，DIRT）样地采集不同处理（对照、去除地上凋落物、去除地下根系、无凋落物输入、添加双倍地上凋落物）的2个土层土壤（0—10，10—20 cm），测定微生物磷脂脂肪酸（phospholipid fatty acid，PLFA）含量 ...

Finding floral and faunal species richness optima among active fire regimes
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

Bright spots for advancing ecological understanding and conservation decision‐making
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract A lot can be learned by studying bright spots—defined as unexpected positive outcomes. In fields like public health, education, and oncology, identifying factors behind bright spots reveals previously unknown drivers of success that can be replicated elsewhere.

Effect of heron nesting on the nitrogen and phosphorus cycles of Acacia confuse forest in uninhabited island [PDF]
, 2011 鹭鸟是鹭科(Ardeidae)鸟类的总称，在我国分布极广，是湿地生态系统中重要的生物类群之一。鹭鸟多营巢于树、竹上，主要以幼鱼、虾、水生昆虫等水生生物和两栖类为食。当其归巢休憩时，会为营巢地带来数量可观的鸟粪。由于鸟粪中富含氮磷元素，必然会对营巢地森林生态系统的氮磷循环产生影响。本研究选取典型无居民海岛厦门市大屿岛白鹭自然保护区的鹭鸟营巢地台湾相思林(Acaciaconfuse)为试验对象，主要通过林地土壤和凋落物研究结合15N自然丰度法，揭示鹭鸟营巢对于森林生态系统氮磷循环的影响 ...

Conservation 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 ...

野生动物学报, 2021 沿海拔梯度选取不同植被群落的12个样地，通过陷阱及铗日法对秦岭南麓中、东段不同群落中小型兽类物种多样性及分布进行调查，累计2 968个工作日，捕获小型兽类2目6科21种，266只，平均捕获率711%。香农-维纳指数和均匀度指数显示，物种多样性在栎林落叶阔叶林最高，农耕带最低。秦岭中段物种多样性呈现出较为明显的中海拔分布格局，而东段的分布格局不甚明显。此外，两区域常见种存在差异，中段主要为中华姬鼠（Apodemus draco）和四川短尾鼩（Anourosorex squamipes），而东段为大林姬鼠（
