Zhongguo shiyan zhenduanxue, 2013 目的探讨原发性宫颈癌人群中NF-κB信号传导通路相关基因多态性与宫颈癌发生发展的关系。方法以广西壮族自治区肿瘤医院2008年9月-2009年9月收治的宫颈癌患者与健康体检者各100名为研究对象,利用限制性片段长度多态性检测法检测研究对象该通路相关基因的基因多态性,进行对比分析。结果 NF-κB信号传导通路相关基因多态性型别在两组研究对象中出现的频率无显著性差别,P>0.05;变异等位基因出现频率与以往结果相一致。结论 NF-κB信号传导通路相关基因多态性与宫颈癌的发生发展无明确的相关关系。

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 ...

不同栖息地类型对东北大兴安岭红花尔基地区鸟类群落结构与组成的影响
野生动物学报, 2010 2001～2002年和2004～2005年分别于5～6月,在内蒙古红花尔基地区,应用样方调查法研究了环境因子与鸟类群落结构的关系,结果表明:（1）在草地生境中,鸟类多样性与草的高度和盖度相关性显著,鸟的密度与草的高度和盖度相关性不显著。（2）在樟子松森林生境中,叶层高度多样性指数（FHD）与鸟类多样性指数（BSD）呈正相关（r=0.814 ...

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

Evaluating the use of taxonomy in the IUCN Red List
Conservation Biology, EarlyView.Abstract Taxonomy defines the units that conservationists strive to preserve for future generations. However, the discovery of new species and the taxonomic revision of existing species affect conservation efforts. Despite the importance of taxonomy for a species’ conservation, there is currently no overview of how those leading species extinction risk

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 ...
