Unique mitochondrial DNAlineages in Irish stickleback populations: cryptic refugium or rapid recolonization?
Abstract Repeated recolonization of freshwater environments following Pleistocene glaciations has played a major role in the evolution and adaptation of anadromous taxa. Located at the western fringe of Europe, Ireland and Britain were likely recolonized rapidly by anadromous fishes from the North A...

To test whether a putative Irish lineage arose from a cryptic Irish refugium, we used approximate Bayesian computation ( ABC ). However, we found no support for this hypothesis.
