Effects of landscape fragmentation on floodplain fishes as revealed by species–habitat networks

Conservation Biology, EarlyView.
Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.

Genetic origins and climate‐induced erosion in economically important Asian walnuts

Conservation Biology, EarlyView.
Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little

Understandings and critiques of biocultural diversity conservation and future recommendations for conservation actors

Conservation Biology, EarlyView.
Abstract As biocultural approaches to conservation gain traction (e.g., through international commitments to Indigenous Peoples and local communities) and external conservation actors increasingly seek to engage with on‐the‐ground holders of biocultural diversity, improved understanding is needed of what biocultural diversity means.

Changes in Key Biodiversity Area networks following national comprehensive assessments

Conservation Biology, EarlyView.
Making comprehensive assessments of Key Biodiversity Area (KBA) networks in a country greatly increases their number and area. Countries that have not yet done so will be missing about half of these globally significant sites and missing the opportunity to get 30 × 30 conservation in the right places. Abstract Key Biodiversity Areas (KBAs) are sites of

肾素－血管紧张素系统基因多态性与冠心病合并慢性心力衰竭的关系

Zhongshan Daxue xuebao. Yixue kexue ban, 2008
【目的】探讨中国南方部分汉族人群的冠心病患者中，肾素－血管紧张素系统中的关键成分即血管紧张素转换酶(ACE)及血管紧张素原（AGT）双基因多态性与冠心病合并慢性心力衰竭（CHF）发病的关系。【方法】 应用聚合酶链反应及限制性片段长度多态性技术，对215例冠心病患者的ACE基因插入/缺失(I/D)及AGT M235T多态性进行检测。将其中105例合并CHF者作为病例组，其余110例心功能正常者作为对照组。【结果】①冠心病合并CHF组DD基因型及D等位基因的频率均高于对照组（前者为45.7％vs23.6 ...

Use of species’ responses to cryptic anthropogenic disturbances for monitoring biodiversity outcomes in tropical forests

Conservation Biology, EarlyView.
Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.
