Cohesion Species Delimitation
We employed the Bond and Stockman (2008) approach by utilizing two criteria to define cohesion species: genetic exchangeability and/or ecological interchangeability, which means that two or more populations exchanging genes and having similar ecological niche attributes are considered a cohesion species. To identify the number of evolutionary lineages, we used the RAxML topology (Figure 2) to establish a baseline evolutionary framework.
