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.

基于mtDNA D-loop区和Cyt b基因序列对鹅喉羚南疆亚种遗传多样性与系统进化地位的分析
野生动物学报, 2022 为进一步明确南疆地区鹅喉羚(Gazella subgutturosa)的遗传分化、遗传多样性水平和系统进化地位,以鹅喉羚南疆亚种(G.s.yarkandensis)为研究对象,运用PCR扩增和测序技术,研究mtDNA D-loop区和mtDNA Cyt b基因的序列特征,利用邻接法构建系统发育树和中介网络关系,以此阐明鹅喉羚南疆亚种的遗传多样性水平和系统进化地位。结果表明:鹅喉羚南疆亚种mtDNA D-loop区序列碱基A、T含量为60.38%,存在23个多态位点,占总位点数的2.90 ...

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Zhejiang Daxue xuebao. Lixue ban, 2010 按胸径将浙江省桐庐县白云源森林公园长叶榧群体划分为成体、小树、幼苗3个年龄级,利用RAPD和ISSR分子标记对不同年龄级的遗传多样性及遗传分化进行分析.12个RAPD引物和12个ISSR引物分别扩增出199和180个条带,总多态位点百分率分别为44.72%和56.11%. RAPD和ISSR分析均显示3个年龄级的多态位点百分率、Shannon信息指数、Nei指数以成体最高,小树次之,幼苗最低,表明长叶榧群体遗传变异呈衰退趋势.分子方差分析(AMOVA)表明长叶榧群体不同年龄级内、年龄级间均存在遗传变异 ...
