Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, EarlyView.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Shuitu Baochi Xuebao, 2004 采用旱棚人工控水，蒸发桶整体称重法，对4种地面覆盖材料、50％覆盖度条件下，土壤水分蒸发与移动性能进行了研究。结果表明，在持续干旱时段，覆盖不仅改善了覆盖区土壤水分状况，而且强化了覆盖区与相邻非覆盖区下层土壤液态水的运移与再分布，提高了相邻非覆盖区下层土壤水分状况，有利于减轻持续干旱对造林成活和幼林生长的威胁。通过非线性参数拟合，首次求得了表征塑料地膜、渗水地膜、干草和塑料泡膜4种地面覆盖材料对土壤蒸发的阻抗特征参数，为建立不同覆盖材料在局部覆盖条件下的土壤蒸发量模型奠定了基础 ...

Conservation Biology, EarlyView.Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Harnessing social media data to track species range shifts
Conservation Biology, EarlyView.Abstract Biodiversity monitoring programs and citizen science data remain heavily biased toward the Global North. Especially in megadiverse countries with limited biodiversity records, incorporating social media data can help address existing data gaps.

Biodiversity‐driven spatial conservation planning to delineate temporally stable regions
Conservation Biology, EarlyView.Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

Watershed Level Risk Assessment of Nitrogen Discharge Using Probabilistic Risk Assessment Tools [PDF]
, 2006 采用故障树及概率分析方法,对九龙江流域氮的流失风险进行定性与定量评价.通过建立故障树定性分析了九龙江流域氮流失的主要风险来源.结果表明,氮流失风险大小主要与肥料施用、畜禽养殖废物的处置及农田耕作有关.在GIS技术支持下,通过土地利用、土壤等数据的计算,结合田间调查结果与专家意见,确定故障树基本故障事件概率,继而对氮流失风险进行定量评价.最佳管理措施模拟评价结果表明,降低施肥水平,在养殖场周边建立植被过滤带,增加河岸林截留入河沉积物等措施可以有效降低氮流失风险,在九龙江流域可以考虑优先实施. 【英文摘要】
