Indo-Pacific Red Lionfish
Indo-pacific red lionfish (Pterois volitans) has invaded at an exponential rate along the Atlantic Seaboard, east to Bermuda, and throughout the Caribbean and Gulf of Mexico. We build a ddRADseq library from samples throughout the introduced part of the range and some samples from the native part of the range. We found evidence of source region for the introduced population near Taiwan and evidence of directional selection between the source and introduced regions. We are working on a grant ot address a population genomic analysis of the lionfish addressing the critical conservation and evolutionary questions related to this invasive species including potential for hybridization in the native range, and directional selection between the core and peripheral populations in the introduced range.
