The collective application of shorebird tracking data to conservation
Conservation Biology, EarlyView.Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Shuitu Baochi Xuebao, 2005 在金沙江干热河谷区的退化草地上进行了2年的氮磷施肥试验,试验结束后分析了土壤特性及土壤微生物数量和生物量的变化。结果表明,在施氮量为5 ,15g/ (m2 ·a)时,土壤微生物的数量和生物量均没有明显变化,而当施氮量增加到2 5g/ (m2 ·a)时,土壤微生物的数量和生物量比对照明显增加。施磷没有引起土壤微生物数量和生物量的明显增加。施氮和施磷均没有引起土壤细菌、真菌和放线菌组成的变化。这表明氮虽然影响土壤微生物的数量,但对土壤微生物的组成没有影响。施氮导致土壤硝态氮增加,但对氨态氮影响不大 ...

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 ...

Zhejiang Daxue xuebao. Lixue ban, 2007 应用氢化物发生-原子荧光光谱方法(HG-AFS)研究了舟山岛海域沉积物和生物样中砷的质量分数并进行了评价，结果如下：1.建立方法的线性方程为，If(As) = 6.166 9 C—1.064 9，方法的检出限为0.2 ng/mL，该法测定两种标准样品的偏差分剐为—6.6%和0.2%.2.沉积物和生物体中均检测到一定量的砷，沉积物中砷质量分数为：12.33~16.49 µg/g，生物样中质量分数为：1.31~17.25 µg/g.参考海洋沉积物和生物质量标准，前者属于一类沉积物，后者属于二类海洋生物 ...

Taxonomic and functional diversity of urban bees of the world
Conservation Biology, EarlyView.Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Emerging applications of large language models in ecology and conservation science
Conservation Biology, EarlyView.Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

Shuitu Baochi Xuebao, 2011 土壤微生物生物量、土壤微生物呼吸及微生物商值(微生物商qMB、微生物呼吸商qCO2)是土壤质量的敏感性指标。对喀斯特峡谷区不同植被恢复阶段土壤微生物生物量、土壤微生物呼吸及其qMB、qCO2进行研究,结果表明:在植被恢复过程中,土壤微生物生物量、土壤微生物呼吸及qMB均表现为从退耕地到草本群落下降,从草本到灌木群落上升,从灌木到乔木群落略微上升或者趋于稳定;qCO2的变化规律与它们相反。在同一恢复阶段,土壤微生物生物量,土壤微生物呼吸,qMB值均随土层加深而减小。土壤微生物生物量、微生物呼吸及其qMB ...

Conservation Biology, EarlyView.Abstract Reversing ongoing biodiversity loss requires effectively managing anthropogenic threats. Although conservation actions can mitigate these threats, prioritizing and targeting such actions remain challenging because species respond differently depending on the nature of the threats and their biological traits.

Conservation Biology, EarlyView.Abstract Site fidelity is the tendency for animals to repeatedly return to the same locations, either within or between years. Site fidelity enables animals to utilize knowledge of previously visited locations, including assessments of seasonal variations in health and mortality risks (e.g., predation), resource availability, and social benefits such ...
