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 ...

Association of the polymorphis ms in STIM1 / ORAI1 / TRPC1 genes with the risk of calcium u rolithiasis [PDF]
, 2015 目的：寻找基质相互作用因子1（Stromalinteractionmolecule1，STIM1）、钙释放激活钙通道调节分子1（Calciumrelease-activatedcalciummodulator1，ORAI1）和瞬时受体电位阳离子通道1（Transientreceptorpotentialcationchannel1，TRPC1）基因中与泌尿系含钙结石发病有关的易感位点及可能存在的单体型，探讨这三者基因多态性与泌尿系含钙结石发病的关联性。 方法：1、采用病例-对照研究策略 ...

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.

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。

Gene structure analysis and differentially splicing between Plasmodium yoelii subspecies [PDF]
, 2016 啮齿类动物约氏疟原虫（Plasmodiumyoelii）是研究宿主-寄生虫相互关系和疟原虫病理分子基础的一种重要的动物模型。尽管约氏疟原虫YM虫株的基本基因组信息已被测定，在最近也有许多啮齿类动物疟原虫的RNA-seq序列信息已见报道，但不同疟原虫品系或者亚种之间可能存在基因编码区及mRNA转录结构上的差异。构建多种疟原虫品系和亚种的cDNA文库将有助于我们对疟原虫遗传模式和转录组结构的认识。 本研究，我们用约氏疟原虫NSM虫株有或无MQ药物压力的红内期原虫样本构建了两个cDNA文库并对其进行深度测序 ...

Conservation Biology, EarlyView.Abstract In the western United States, conservation practitioners are increasingly working with private landowners to restore habitat for North American beavers (Castor canadensis) and to use nonlethal mitigation techniques when beavers damage crops and infrastructure.

Zhongguo shiyan zhenduanxue, 2012 目的探讨血管紧张素原（AGT）基因M235T多态性与中国人群结直肠癌易感性的关系。方法采用聚合酶链反应-限制性片段长度多态性方法检测结直肠癌组151例患者和健康对照组202例AGT基因M235T多态性。结果结直肠癌组与对照组AGT20M235T基因型和等位基因分布差异无统计学意义（P>0.05）。根据临床病理特征进行分层分析,发现携带TT基因型个体患低分化结直肠癌的风险比携带MT/MM基因型高2.50倍（P=0.008,OR=2.50;95%CI,1.26-4.97 ...

污水处理厂中浮游生物群落DNA指纹及其与水质指标的关系 [PDF]
, 2008 以武汉龙王嘴污水处理系统为研究对象,揭示了污水处理各阶段中浮游生物群落的DNA指纹拓扑结构,进而探索了其与浮游生物群落结构和环境理化因子的关系.首先建立了污水处理系统中浮游生物群落总DNA提取方法,然后用原核与真核特异性引物对流程(A2/O氧化沟工艺)中不同阶段的浮游生物群落总DNA进行PCR扩增,用变性梯度凝胶电泳(DGGE)检测,并对平行水样分别进行常规理化因子和浮游生物物种的检测与鉴定.结果显示,各采样点理化因子、物种组成与浮游生物DNA指纹的统计分析结果十分吻合,厌氧、缺氧和好氧阶段间差异较小,

Effects of political identity activation and inaccurate metaperceptions on attitudes toward wolves
Conservation Biology, EarlyView.Abstract Polarization between groups can undermine durable conservation outcomes. Activating group identities (i.e., an individual's sense of self derived from membership in a group) can exacerbate differences, especially when people hold inaccurate perceptions of their peers and rivals.
