“…Much more surprising is the deep phylogeographic break found on either side of the Apalachicola River estuary, with over 5% divergence among mtDNA lineages on either side. The Apalachicola River is a well-known barrier to gene flow for terrestrial organisms (Donovan, Semlitsch, & Routman, 2000;Pauly, Piskurek, & Shaffer, 2007) and freshwater fish (Bagley, Sandel, Travis, Lozano Vilano, & Johnson, 2013;Bermingham & Avise, 1986;Nedbal, Allard, & Honeycutt, 1994;Wooten & Lydeard, 1990), but this is to our knowledge the first reported case for a similar phylogeographic break in a marine fish, although at least one marine mollusk, the arrow squid (Loligo plei), was found to show a break there as well (Herke & Foltz, 2002).…”

The adaptive radiation of the seven-spined gobies (Gobiidae: Gobiosomatini) represents a classic example of how ecological specialization and larval retention can drive speciation through local adaptation. However, geographically widespread and phenotypically uniform species also do occur within Gobiosomatini. This lack of phenotypic variation across large geographic areas could be due to recent colonization, widespread gene flow, or stabilizing selection acting across environmental gradients. We use a phylogeographic approach to test these alternative hypotheses in the naked Haplotype phylogenies and spatial patterns of genetic diversity reveal frequent population bottlenecks followed by rapid population growth, particularly along the Gulf of Mexico. The magnitude of the genetic divergence among intraspecific lineages suggests the existence of cryptic species within Gobiosoma and indicates that modes of speciation can vary among lineages within Gobiidae.

“…Although the genetic diversity of both mosquitofish species has been thoroughly analyzed in the native populations of North America (Stearns 1983;Wooten and Lydeard 1990;Scribner and Avise 1994;Mulvey et al 1995) and in G. holbrooki introduced to Australia (Congdon 1994(Congdon , 1995, the only study in Europe is Grapputo et al (2006), performed only on four collections from Italy and Spain. Interestingly, founder events and population bottlenecks in early stages of introductions, which are considered responsible for the loss of diversity of many invasive species (Allendorf and Lundquist 2003;Roman and Darling 2007;Dlugosch and Parker 2008;Suarez and Tsutsui 2008), were observed in these four European mosquitofish populations.…”

We provide mitochondrial sequence variation of the invasive fish Gambusiaholbrooki from 24 European populations, from Portugal to Greece. Phylogeographic structure in Europe was compared with genetic data from native samples (USA) and historical records were reviewed to identify introduction routes. Overall, data agree with records of historical introductions and translocations, and indicate that the most abundant haplotype throughout Europe originated from North Carolina and corresponded to the first introduction in 1921 to Spain, being transferred to Italy in 1922 and to many countries afterwards. Our results also show that at least another independent introduction occurred first in France and subsequently from France to Greece. Haplotypes of G. affinis were not detected in our European sampling effort but historical records and other data suggest that this species was introduced to Italy in 1927 and it might be present. At the continental scale, there is less diversity in Europe than in North America, in agreement with the low number of introduced fish. At the local scale, some European populations gained diversity from multiple introductions and from "de novo" mutationsThis study was financially supported by the Spanish Ministry of Education (CGL2006-11652-C02-02/BOS) and the Government of Catalonia (Catalan Government Distinction Award for University Research 2004 to EGB

“…The eastern mosquitofish, G. holbrooki, is a small, livebearing fish of the family Poeciliidae native to the southeastern United States (Rosen and Bailey, 1963;Wooten et al, 1988;Wooten and Lydeard, 1990). It and its sister-species, the western mosquitofish (G. affinis), have been introduced worldwide as mosquito-control agents.…”
