Genetic signature of a recent invasion: The ragged sea hare Bursatella leachii in Mar Menor (SE spain)

In the last years, bioinvasions are increasing their ecological and economic impacts on different habitats all over the world, and are therefore becoming the target of much recent research (Ricciardi et al., 2004, Bernardi et al., 2010, Zenetos et al., 2012). The leading hypothesis for the origin of invasions is that colonization by invasive species is most often associated with founder events of introduction by occasional windows of opportunity (Montefalcone et al., 2010, Zhan et al., 2010), although distinct invasion processes might occur simultaneously in different parts of the invaded range, and some can create local accumulation of genetically distinct invaders. In a typical invasion scenario, however, the few founders are then the source of rapid demographic expansions in the new habitats. Such processes result in extreme genetic diversity loss. Biological invasions thus contradict the paradigm of genetic diversity being essential for adaptation to novel habitats.
