Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia
Conservation Biology, EarlyView.Abstract The international trade in live birds poses risks to animals, people, and biodiversity. To effectively mitigate these risks, decision‐makers require information on the volume, dynamics, and direction of trade. Despite Africa once being the largest exporter of birds by region, very little data exist on recent trade in live birds not listed on ...

Genetic Analysis on Grain Shape and Mapping, Cloning and Characterizing of Major Grain length Gene in rice [PDF]
, 2014 水稻是世界上最重要的禾谷类作物之一，提高水稻产量和改善稻米品质是水稻遗传与育种研究的永恒主题。水稻粒形是粒长、粒宽、长宽比及粒厚的综合性状，是稻米外观品质的重要指标，同时对稻米的碾磨品质、食味品质及产量均有重要影响。厦门大学水稻遗传育种研究室长期致力于大粒优质水稻新品种的遗传与育种研究，前期采用60Co-γ射线辐照水稻成熟花粉诱变方法，获得了一批遗传上稳定的长粒大粒水稻种质材料并广泛应用于优质籼稻育种中。为了解这些大粒材料谷粒性状的遗传基础，本研究选择其中的三个大粒品系JF171、JF178 ...

A more‐than‐human political ecology of Indonesian songbird trade
Conservation Biology, EarlyView.Abstract Since its inception, conservation science has considered wildlife trade a problem. In focusing on conservation outcomes, conservationists almost completely ignore the welfare of traded animals and plants and the harms they endure. We developed a political ecology approach that incorporates the interconnectedness of people with animals and ...

MDR1基因+3435C/T基因型单核苷酸多态性对硼替佐咪治疗的多发性骨髓瘤预后的影响
Zhongguo shiyan zhenduanxue, 2013 目的探讨MDR1基因+3435C/T的单核苷酸多态性对硼替佐咪治疗的多发性骨髓瘤患者预后的影响。方法采用DNA测序方法检测MDR1基因+3435C/T的单核苷酸多态性;应用Kaplan-Meier来确认MDR1基因+3435C/T的单核苷酸多态性对硼替佐咪治疗/未治疗患者生存率的影响。结果 52.8%（n=47）的多发性骨髓瘤患者MDR1+3435位点的基因型为C/T,其余多发性骨髓瘤患者MDR1+3435位点的基因型均为T/T。MDR1+3435C/T基因型的患者的平均生存期为43.3月,而MDR1 ...

Conservation Biology, EarlyView.Abstract Procedural, distributional, recognitional, and epistemic justice aspects of conservation interventions are well documented in contexts where pastoralism is a key livelihood and way of life. Geospatial analyses and representations of wildlife conservation and restoration that are increasingly applied in pastoralist rangeland socioecological ...

糖尿病、冠心病患者ABCA1基因R219K多态性的频率分布特点
Zhongguo shiyan zhenduanxue, 2011 目的旨在探讨我国北方地区汉族人ABCA1基因R219K多态性的频率分布特点,对血脂水平的影响,及其与冠心病、糖尿病和糖尿病合并冠心病的关系。方法采用改良碘化钠法提取基因组DNA,聚合酶链反应限制性片段长度多态性（PCR-RFLP）法分析ABCA1基因R219K多态性。结果正常对照组ABCA1基因R219K多态性RR、RK、KK基因型频率、R等位基因频率、K等位基因频率分别为28.5%、48.6%、22.9%、52.8%、47.2%;糖尿病组分别为29.6%、63.9%、6.5%、61.5%、38.5 ...

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework
Conservation Biology, EarlyView.Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.
