The Origin and Invasion Pathway of Brown Rats Rattus norvegicus on Dok-Do Island Revealed by Genome-Wide Markers from 3-RADseq Approach

ABSTRACT:

Simple Summary

Biological invasion on islands poses ecological threats, and understanding invasion pathways can aid in preventing invasive species. Recently, brown rats (Rattus norvegicus) arrived on Dok-do, a remote, small island in the East Sea of Korea. Due to strict regulation on human disturbances, including trapping, we adopted 3-RADseq to compensate for our small sample size and determine the origin of the invading rats. Our genomic analysis will aid in controlling and managing invasive species on this protected island.

Abstract

Biological invasions are known to cause local extinctions on islands. Dok-do, a small, remote volcanic island in the East Sea of Korea in the western Pacific, has recently been invaded by rats, posing ecological problems. To infer their ori
