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.

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.

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.

Shuitu Baochi Xuebao, 2016 采用电磁感应(EMI)、地统计学半变异函数和Kriging空间插值方法研究小泊湖退化湿地土壤盐分的空间分布。结果表明：土壤表观电导率(ECa)和0—40 cm土壤盐分呈线性显著正相关，说明在小泊湖湿地土壤表观电导率的变化可以用以反映土壤盐分含量的变化；半变异函数分析表明，土壤盐分具有强空间相关性[C/(C0+C)＞0.5]，其空间分布主要是由结构性因素引起的；高斯模型(R2=0.98)插值土壤盐分表明，土壤盐分空间分布与退化湿地的空间分布表现出明显的一致性，放牧活动强烈的退化区域土壤盐分相对较高 ...

Evaluating the empirical basis for threat attribution in the IUCN Red List
Conservation Biology, EarlyView.Abstract Understanding the impacts of different threats on species is key to successful conservation interventions and policies. The International Union for Conservation of Nature (IUCN) assesses threats to species, and the organization's Red List of Threatened Species is a key conservation tool.

Zhongguo shiyan zhenduanxue, 2008 目的为了研究AQP1在胃腺癌分化中的表达和作用。方法采用HE法和SP免疫组织化学法研究不同分化程度的人胃腺癌的AQP1的表达。结果高、中分化的胃腺癌细胞形成腺泡,并且AQP1表达于其细胞质和细胞膜,在它们的细胞质中可见阳性反应的泡状结构;无腺泡形成的低分化的腺癌细胞不表达AQP1,有腺泡形成的低分化腺癌细胞具有弱阳性AQP1。结论AQP1参与胃腺癌细胞的分化和外分泌功能。

Zhejiang Daxue xuebao. Lixue ban, 2016 用HZSM-5，USY-1，H-beta 3种不同类型的分子筛对木屑的快速热裂解气进行原位催化转化.研究了不同分子筛对积碳量、生物油产率、生物油组分分布的影响.实验结果表明，分子筛积碳量排序为：USY-1>H-beta> HZSM-5.生物油产率在使用催化剂后有所降低，并且HZSM-5产生的生物油产率最高.使用催化剂后生物油组分种类和含量都有明显的变化.3种分子筛中，HZSM-5催化产生的烃类含量大大增加，轻质苯酚含量也明显增加，重质苯酚和糖类含量明显降低，催化效果显著 ...

Conservation Biology, EarlyView.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...
