Molecular Phylogeny of North Mediterranean Freshwater Barbs (Genus Barbus: Cyprinidae) Inferred from Cytochrome b Sequences: Biogeographic and Systematic Implications

Phylogeny of the gudgeons (Teleostei: Cyprinidae: Gobioninae)

“…Recent molecular studies (e.g. Tsigenopoulos and Berrebi, 2000;Machordom and Doadrio, 2001;Tsigenopoulos et al, 2003) have provided additional evidence corroborating Howes (1987). Arai (1982) ascribed Gobiobotia and Microphysogobio to a distinct subfamily Gobiobotiinae, but he did observe that the diploid chromosome number of both genera matched that found in gobionines, prompting him to suggest that gobiobotiines were derived from gobioniines.…”

Phylogenetic relationships among Spanish Barbus species (Pisces, Cyprinidae) shown by RAPD markers

“…Molecular studies have been performed on barbel samples using different markers (Tsigenopoulos et al, 1999;Tsigenopoulos and Berrebi, 2000) in an attempt to clarify whether there is one lineage for each different ecophenotype or whether groups of Barbus species represent clusters of morphologically convergent taxa. The results have provided contradictory conclusions in this respect.…”

“…Studies based on morphology, osteology, ecology and, to a lesser extent, on genetics, have all made contributions to the present understanding of the Barbus genus Granado-Lorencio, 1988, 1997;CollaresPereira and Madeira, 1990;Torralva et al, 1997;Aparicio and Sostoa, 1998;Chenuil et al, 1998Chenuil et al, , 2000Tsigenopoulos et al, 1999, Callejas andOchando, 2000;Tsigenopoulos and Berrebi, 2000). However, basic questions on its evolutionary differentiation remain unsolved (see Tsigenopoulos and Berrebi, 2000 and references therein).…”

Variation patterns of the mitochondrial 16S rRNA gene with secondary structure constraints and their application to phylogeny of cyprinine fishes (Teleostei: Cypriniformes)

“…Molecular phylogenetic investigations of the subfamily have focused only on subgroups, including species-level analyses (Tsigenopoulos et al, 1999;Tsigenopoulos and Berrebi, 2000;He et al, 2004a,b), genus-level analyses (He et al, 2004a,b;Li et al, 2005), and intertribal evaluations (Cunha et al, 2002;Liu and Chen, 2003;He et al, 2004a,b;Wang et al, 2007). All of these analyses have failed to corroborate lineages previously identified in morphological-based classifications or resolve deep-level relationships in the subfamily.…”
