Description
Summary:Invasive species have been associated with significant negative impacts in their introduced range often outcompeting native species, yet the long-term evolutionary dynamics of biological invasions are not well understood. Hybridization, either among waves of invasion or between native and introduced populations, could alter the ecological and evolutionary impacts of invasions yet has rarely been studied in marine invasive species. The European green crab (Carcinus maenas) invaded eastern North America twice from northern and southern locations in its native range. Here we examine the frequency of hybridization among these two distinct invasions at locations from New Jersey, USA to Newfoundland, Canada using restriction-site associated DNA sequencing (RAD-seq), microsatellite loci, and COI mtDNA sequences. We used Bayesian clustering and hybrid assignment analyses to investigate hybridization between the northern and southern populations. Of the samples analyzed, six locations contained at least one hybrid ... : Microsat_GenepopGenepop file of all microsatellite alleles for green crabgreen_crab_RAD_FilteredGenepop file of RAD-seq derived loci after filtering for missing data and individuals with low coverage.FinalMicrosat_Renamed_Genepop_ForSim_S1R1_NHNewHybrids file of simulated individuals for power analyses using microsatellite dataSimulated_RAD_Data_ForNewHybridsSimulated Pure 1, Pure 2, F1, F2, and BC1 and BC2 individuals using the top 200 high Fst low linkage disequilibrium loci for testing power of the SNP panel.Final_Renamed_Genepop_ForSim_200_Loci_Panel_S1R1_NH.txt ...
