“…The GenBank data set included 21 sequences of Gambusia spp. and one outgroup species, Belonesox belizanus, described in Lydeard et al (1994) (GenBank codes U18115.1, U18206.1 to U18209.1 and U18211.1 to U12228.1), three sequences of G. affinis and 3 of G. heterochir described by Davis et al (2006) (GenBank codes DQ075681.1 to DQ075686.1) and four sequences of four other Gambusia species reported by Hrbek et al (2007) (GenBank codes EF017514.1 to EF017516.1 and EF017518.1). All sequences were aligned using ClustalW Multiple Alignment accessory application implemented in the Bioedit software (Hall 1999) and the G. affinis EF017514.1 sequence as reference.…”

“…Four of them were assigned to G. affinis because they clustered together with GenBank EF0175141 (Hrbek et al 2007) and DQ075681.1 (Davis et al 2006) G. affinis sequences. The other eight haplotypes grouped, with strong bootstrap support, with G. holbrooki GenBank sequence U18210.1 of Lydeard et al (1994) (Fig.…”

Origin and genetic diversity of mosquitofish (Gambusia holbrooki) introduced to Europe

et al. 2009

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 Evolutionary Consequences of Dams and Other Barriers for Riverine Fishes

et al. 2022

View full text Add to dashboard Cite

Dams and other anthropogenic barriers have caused global ecological and hydrological upheaval in the blink of the geological eye. In the present article, we synthesize 307 studies in a systematic review of contemporary evolution following reduced connectivity and habitat alteration on freshwater fishes. Genetic diversity loss was more commonly observed for small populations impounded in small habitat patches for many generations behind low-passability barriers. Studies show that impoundments can cause rapid adaptive evolution in migration timing, behavior, life history, temperature tolerance, and morphology, as well as reduce phenotypic variance, which can alter adaptive potential and ecological roles. Fish passage structures can restore migratory populations but also create artificial selection pressures on body size and migration. The accelerating pace of dam removals and the paucity of data for fishes other than salmonids, other vertebrates, invertebrates, and tropical and southern hemisphere organisms highlights the urgent need for more studies on the rapid evolutionary effects of dams.
