Mitochondrial genetic population structure and variation of the littoral earthworm Pontodrilus longissimus Seesamut and Panha, 2018 along the coast of Thailand

Nucleotide sequences of a 658 bp DNA fragment of the cytochrome c oxidase subunit 1 were used to investigate the population structure, phylogeographical pattern and genetic variation of Pontodrilus longissimus Seesamut and Panha, 2018 sampled from 16 localities along the coastline of Thailand. Bayesian inference, maximum likelihood analyses and the application of a haplotype network showed clearly that there were two geographically isolated...
