Table 5 Analysis of molecular variance (AMOVA) testing for partition of the genetic variance among populations of Eriphia verrucosa under different biogeographic hypotheses

From: Phylogeographic and evolutionary history analyses of the warty crab Eriphia verrucosa (Decapoda, Brachyura, Eriphiidae) unveil genetic imprints of a late Pleistocene vicariant event across the Gibraltar Strait, erased by postglacial expansion and admixture among refugial lineages

Tested hypotheses of population genetic structure across potential barriers to gene flow

F-statistics based on Tajima and Nei distance

F-statistics based on haplotype frequency

1-Genetic structure across the Gibraltar Strait:

 Atlantic Ocean (Azores, Canary Islands, Sesimbra) vs. Mediterranean Sea (Alboran Sea, Alicante, Valencia, Tarragona, Tyrrhenian Sea, Northern Tunisia, Eastern Tunisia, Tripoli, Istra, Ionian Sea, Aegean-Black seas, Levantine Sea)
