Insights for conservation from the Ecological Knowledge Games project
Conservation Biology, EarlyView.Abstract Environmental conservation research requires robust methods for collecting large‐scale behavioral data and engaging diverse stakeholders in decision‐making processes. We (Y.P., A.B.D., and N.B.) created EcoKnowGames (Ecological Knowledge Games), a transdisciplinary project that develops knowledge games for conservation science and data ...

Scientists’ warning on the global destruction of rock outcrop ecosystems
Conservation Biology, EarlyView.Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

E-选择素基因rs3917422A和rs5355C位点多态性与哈尼族原发性高血压相关性研究
Zhongguo shiyan zhenduanxue, 2009 目的探讨E-选择素基因rs3917422A\C和rs5355C\T位点多态性与哈尼族原发性高血压的关系。方法采用PCR测序技术,对云南哈尼族172例原发性高血压患者和133例正常对照的E-选择素基因rs3917422A\C和rs5355C\T的错义突变进行检测。结果在哈尼族中未发现有rs3917422A多态存在,发现rs5355C基因有多态存在。rs5355C等位基因频率在原发性高血压组中为10.5%,正常对照组中为13.2%,两组之间无显著性差异（P=0.311,P>0.05）。结论哈尼族中E ...

Twelve principles for successful governance of community‐based coastal marine restoration
Conservation Biology, EarlyView.Abstract Global agreements, such as the Global Biodiversity Framework, call for urgent, large‐scale action to halt biodiversity loss through a whole‐of‐society approach. Community‐based restoration can play a crucial role in achieving this goal, yet there remains limited understanding of what makes these projects effective and sustainable.

Conservation Biology, EarlyView.Abstract Ecological niche models (ENMs) are used to assess the abiotic preferences of species by linking their occurrences to the environmental conditions in which they live. We developed a fossil‐informed ENM framework that integrates mid‐Holocene and modern occurrences to test niche stability and reconstruct abiotic niche characteristics for four ...

Fbgβ455基因多态性与CRP协同作用对动脉粥样硬化的影响
Zhongguo shiyan zhenduanxue, 2010 目的研究血浆纤维蛋白原Fbgβ455基因多态性与此反应蛋白CRP的协同作用对动脉粥样硬化的影响。方法采用限制性长度多态性聚合酶链反应检测血浆Fbgβ455基因态性及免疫比浊法检测CRP。结果心肌梗塞组与冠心病组患者外周血基因组DNAFbgβ455多态性分布G/G,G/A,A/A具有显著性差异（P0.05）。结论血浆Fbgβ455等位基因型G/A,A/A可能是急性心肌梗塞发病的遗传性危险因素,Fbgβ455与CRP在动脉硬化的发生过程中无协同作用。

Assessing and strengthening community‐based coastal governance
Conservation Biology, EarlyView.Abstract Community‐based coastal governance is essential for biodiversity conservation and sustainable livelihoods, yet many communities continue to face significant challenges in establishing and sustaining effective governance systems. We sought to improve understanding of the current status of community‐based coastal governance across five countries
