Environmental DNA sequencing will enable scientists to explore Amazon piscine diversity without catching fish

Publicado em 23 novembro 2021
A scientific expedition in the Javari River basin on the border between Brazil, Colombia and Peru has shown use of environmental DNA sequencing to be feasible to investigate fish diversity in the Amazon. The eDNA method consists of extracting molecules of DNA present in water samples and identifying the species to which they belong by means of genetic markers. An article on the research published in the journal Scientific Reports also discusses the limitations of the technique for the study of [...]
