野生动物学报, 2022 棕熊(Ursus arctos)是我国二级重点保护野生动物,棕熊鉴定是生物资源调查和多样性保护的一项重要内容,更是解决人兽冲突和打击珍稀动物非法盗猎的重要技术手段之一。研究设计棕熊物种鉴定特异性PCR引物,建立基于粪便材料的棕熊特异性PCR鉴定方法,并对粪便材料进行物种鉴定。结果表明:研究设计的棕熊特异性引物可以鉴别藏棕熊(U.a.pruinosus)、东北棕熊(U.a.lasiotus)和喜马拉雅棕熊(U.a.isabellinus)等亚种且具有较高的特异性,能从粪便材料中高效特异性地鉴定藏棕熊 ...

Rare Metals, EarlyView.ABSTRACT Efficient and durable bifunctional electrocatalysts are vital for scalable water electrolysis. Here, we realize cobalt‐vacancy (Covac) engineering in CoFeP supported on N,P‐codoped carbon nanocages (Co1‐vacFeP/NPC) through a simple route comprising a CoFe Prussian blue analog precursor, phosphidation–pyrolysis, tannic‐acid etching, and a ...

Methods in Ecology and Evolution, EarlyView.Abstract DNA barcode‐based species identification has become pivotal in biodiversity research. Current barcoding‐based deep learning methods have advantages in species identification but exhibit significant limitations. By using COI barcoding alone, previous studies were unable to fully capture species identification features. Prior methods showed that
