Redistribution of the geographical ranges of the Iberian cyprinid genus Pseudochondrostoma based on a phylogenetic analysis: implications for the historical rearrangements of the north‐western Iberian drainages

Abstract

A new distribution range is proposed for Pseudochondrostoma polylepis and Pseudochondrostoma duriense based on the phylogeny of two nuclear and one mitochondrial gene sequences, with implications on the geographic history of the north-western Iberian drainages.

MtDNA markers reveal the existence of allopatric evolutionary lineages in the threatened lampreys Lampetra fluviatilis (L.) and Lampetra planeri (Bloch) in the Iberian glacial refugium

“…The dissimilarity of ecological conditions between the tributaries of both banks may have promoted the isolation and differentiation of populations when the Tagus river basin gained its present configuration. The differentiation of the populations from the Vouga river basin and its close neighbour the Esmoriz river is somehow surprising, considering the paleogeological evidences (Rodrigues and Dias 1989) and previous phylogeographic studies with other freshwater fishes (Aboim et al 2009;Sousa-Santos et al 2007), which suggest recent connections between these basins and the Douro and the Mondego drainages. In fact, in the Pleistocene, connections between the Mondego and Douro and the Mondego and Vouga drainages were still possible (Rodrigues and Dias 1989), allowing the dispersal of freshwater fishes between these basins (Sousa-Santos et al 2007).…”

Introgressive hybridization as a promoter of genome reshuffling in natural homoploid fish hybrids (Cyprinidae, Leuciscinae)

“…For this reason, a genetic analysis on all 200 individuals was also included (see Supplementary Material), based on molecular markers previously developed for the parental species-mtDNA cyt b gene, 10 microsatellite loci (Aboim et al, 2010) and the single-copy RAG-1 nuclear gene (recombination activating gene 1) (Aboim et al, 2009). Representative sample sizes of each parental species per population/river/basin were considered, as well as the independent Figure 1 Sampling locations K across the distribution ranges of AOL, PDU and PPO in the Iberian Peninsula.…”

Cytogenetic survey of species of two distinct genera of Iberian nases (Cyprinidae, Leuciscinae) that hybridize extensively in nature. I. Evidence of a similar and conserved chromosome pattern with some few species-specific markers at macro-structural level

“…Both sister-species P. duriense and P. polylepis extend their distribution ranges to the north-western and centralsouthern parts of the Peninsula, respectively (Aboim et al 2009), and occur quite frequently in sympatry with Achondrostoma oligolepis (a Portuguese endemic inhabiting the drainages between Lima and Tejo) and Achondrostoma arcasii (an Iberian endemic confined to the northeast part of Portugal but extending from Galicia to the Mediterranean slope in Spain- Doadrio 2002).…”
