Previous studies have given substantial attention to external factors that affect the distribution and diversification of freshwater fish in Europe and North America, in particular Pleistocene and Holocene glacial cycles. In the present paper we examine sequence variation at one mitochondrial and four nuclear loci (over 3kbp) from populations sampl...
Genetic surveys of the endemic Padanian barbel Barbus plebejus (Osteichthyes: Cyprinidae) were completed on the lowland Adda River, a heavily regulated Italian Alpine river in which the European Barbus barbus is invasive. Both Barbus species are of the large fluvio-lacustrine ecophenotype and thus they share habitats in the river. Mitochondrial (N...
The presence of the Iberian barbel Luciobarbus graellsii is recorded for the first time in the Tiber River (Central Italy). Because of its abundance at the sampling site and the presence of different size classes we assume that the species is established. Introduction of the allochthonous species is probably due to illegal release by local anglers....
Il genere Barbus è costituito da specie ittiche primarie distinte in due gruppi monofiletici contraddistinti da diversa vocazione ecologica: specie reofile e fluvio-lacustrine. Nota l’elevata plasticità del genere, sono probabili fenomeni di ibridazione nelle zone di sutura lungo il tratto fluviale. In questo studio è stato indagato il mescolamento...
RIASSUNTO -Studio preliminare della filogenesi del genere Barbus nel fiume Po -Il genere Barbus è caratterizzato da una complessa struttura tassonomica. Nel distretto ittiogeografico Padano-Veneto sono state identificate due specie autoctone: Barbus caninus, specie prettamente reofila, e Barbus plebejus, reofilo anch'esso, ma distribuito più a vall...
