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 ...

Conservation Biology, EarlyView.Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Integrative Conservation, Volume 4, Issue 3, Page 277-286, September 2025.This study provides an innovation to address the challenge in accessibility to samples and genetic markers in Snow leopard conservation genetic studies. We performed next‐generation sequencing (NGS) on 19 fecal samples obtained from the eastern Qinghai‐Tibet Plateau, and successfully assembled 17 complete mitogenome sequences (~16,720 bp) and ...

, 2012 大头鲤(Cyprinus pellegrini)是一种云南高原湖泊特有的国家Ⅱ级重点保护鱼类。土著种大头鲤与外来种鲤(C.carpio)的渐渗杂交在星云湖野生种群中已经广泛发生。本研究结合形态和微卫星及线粒体DNA分析检测了螺蛳铺大头鲤原种种群的遗传现状。结果显示,螺蛳铺大头鲤样本所有个体在形态上位于大头鲤与鲤的参照样本之间;在微卫星因子对应分析中也显示,其位于大头鲤与鲤的参照样本之间,但与大头鲤参照样本较为相似;在线粒体DNA分析中显示,都具有鲤的单倍型 ...

Systematic Entomology, Volume 50, Issue 3, Page 495-518, July 2025.Using genomic data from 285 species across 19 planthopper families, we conducted the first phylogenomic study targeting global planthoppers and inferred their phylogeny with the highest resolution so far. We proposed taxonomic changes including the establishment of a new family Borysthenidae stat. rev. and a new superfamily Meenoploidea superfam.
