Data from: Global connectivity patterns of the notoriously invasive mussel, Mytilus galloprovincialis Lmk using archived CO1 sequence data.

The invasive mussel, Mytilus galloprovincialis has established invasive
populations across the globe and in some regions, have completely
displaced native mussels through competitive exclusion. The objective of
this study was to elucidate global connectivity patterns of M.
galloprovincialis strictly using archived cytochrome c oxidase 1 sequence
data obtained from public databases. Through exhaustive mining and the
development of a systematic workflow, we compiled the most comprehensive
global CO1 dataset for M. galloprovincialis thus far, consisting of 209
sequences representing 14 populations. Haplotype networks were constructed
and genetic differentiation was assessed using pairwise Analysis of
Molecular Variance. There was significant genetic structuring across
populations with significant geographic patterning of haplotypes. In
particular, South Korea, South China, Turkey and Australasia appear to be
the most genetically isolated populations. However, we were unable to
recover a northern and southern hemisphere grouping for M.
galloprovincialis as was found in previous studies. These results suggest
a complex dispersal pattern for M. galloprovincialis driven by several
contributors including both natural and anthropogenic dispersal mechanisms
along with the possibility of potential hybridization and ancient
vicariance events.
