Integrative Conservation, EarlyView.Accurate species identification is critical for conserving endangered Firmiana trees in China. However, morphological similarities among closely related Firmiana species complicate its taxonomic identification. We conducted genome skimming on 62 samples representing all 10 Chinese species and discovered nrITS as the optimal DNA barcode, achieving 100 ...

Integrative Conservation, EarlyView.Implementing ecosystem restoration remains challenging for policymakers and practitioners. Focusing on Rwanda, we used a participatory world‐café approach involving scientists, practitioners, and decision‐makers working on ecosystem restoration to identify emerging challenges and future research priority areas. We identified five critical frontiers for

Design of multivalued shift-register type counter(多值移位型计数器设计)
Zhejiang Daxue xuebao. Lixue ban, 2005 分析和讨论了基于全状态图的多值移位型计数器的设计方法，指出了当将该方法用于更多值的移位型计数器的设计时，将变得非常复杂，失去了直观性和方便性的特点.提出了多值全状态表及基于全状态表的多值移位型计数器设计方法.此方法能解决上述问题，并给出了二变量四值移位型计数器的设计实例.

Population genetic structure and phylogentic analysis for Morone americana in Delaware Bay of United States [PDF]
, 2016 美洲狼鲈(Moroneamericana，Gmelin，1789)隶属于鲈形目(Perciformes)，狼鲈科(Moronidae)，狼鲈属(Morone)，别名美洲白鲈、白石鮨。美洲狼鲈是在美国东海岸浅海区域十分常见的一种溯河洄游鱼类，每逢春末夏初，生活于近海和河口区域的美洲狼鲈便溯河洄游至河流中上游产卵繁衍。美洲狼鲈也经常被用作海区污染程度的指示种。鉴于美洲狼鲈广泛的分布范围以及巨大的种群数量，其十分适合作为近岸洄游性鱼类群体研究的模式种类。同时，其在检测环境污染方面也具有主要作用 ...

Integrative Conservation, EarlyView.We profiled nutritional and physiological markers in captive sifakas, endangered primates from Madagascar, managed in expansive, non‐native forest enclosures. Variation in many markers reflects freely foraged diets and the energy required to maintain homeostasis under more naturalistic conditions.

Characterizing China's Illegal Trade in Avifauna on Social Media 中国社交媒体上非法鸟类贸易的特征分析
Integrative Conservation, EarlyView.Worldwide, illegal wildlife trade is an increasing threat to species conservation. Here, we used the social media data to characterize China's illegal online trade in avifauna for conservation implications. Our results found that 178 avian species have been posted online for illegal trading. ABSTRACT The illegal wildlife trade poses a growing threat to

Protein phosphatase 2A-B55δ enhances chemotherapy sensitivity of human hepatocellular carcinoma under the regulation of microRNA-133b [PDF]
, 2016 目的：原发性肝细胞癌(hepatocellularcarcinoma，HCC)是我国公共卫生关注的热点问题之一，寻找增强HCC化疗敏感性的有效干预靶点具有重要意义。蛋白磷酸酶2A(proteinphosphatase2A，PP2A)是重要的肿瘤抑制因子；PPP2R2D基因编码的PP2A-B55δ亚基参与细胞周期有丝分裂调控。我们前期研究验证了PPP2R2D基因3’-非翻译区(3’-untranslatedregion，3’UTR)的+15G>C多态性位点受微小RNA-133b(microRNA-133b，

Integrative Conservation, EarlyView.Key Largo woodrats are a small and endangered island species, whose individuals tend to occur in family groups. Isolation from mainland populations, predation, and habitat fragmentation have caused genetic drift, leading to low overall diversity. Here, we found that a major category 4 hurricane promoted genetic diversity in the Key Largo woodrat ...
