Invasion of non-native species exposed by environmental DNA

Monday, September 7, 2015 - 05:30 in Biology & Nature

A research group, headed by Dr. MINAMOTO Toshifumi (Project Assistant Professor, Graduate School of Human Development and Environment, Kobe University), Dr. UCHII Kimiko (Assistant Professor, Faculty of Pharmacy, Osaka Ohtani University), and Dr. DOI Hideyuki (Graduate School of Simulation Studies, University of Hyogo), have used environmental DNA (eDNA) to quantify the proportion of Japanese native common carp to non-native strains from the Eurasian continent. Their method is based on single nucleotide polymorphism (SNP), and it is hoped that this novel approach will facilitate the detection of non-native genotypes in various species. The findings were published in Molecular Ecology Resources on August 27.
