Article
Full-text available
Understanding the mechanisms underlying diversification and speciation by introgressive hybridization is currently one of the major challenges in evolutionary biology. Here, the analysis of hybridization between two pairs of Iberian Leuciscinae provided new data on independent hybrid zones involving Achondrostoma oligolepis (AOL) and Pseudochondros...
Article
Six microsatellite loci were identified for the demersal deep-sea fish Helicolenus dactylopterus. All loci were highly polymorphic (5–21 alleles per locus). Observed heterozygosities were from 0.378 to 0.868, while the expected heterozygosities ranged from 0.529 to 0.925. Multiplex PCR reactions were optimized. Microsatellite markers were developed...
Article
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.
Article
Full-text available
Pseudochondrostoma duriense and Achondrostoma oligolepis are two Iberian endemic cyprinid fish species that occur in sympatry over most of their distribution range and that are suspected to hybridize in nature. Here, we employed a combination of mitochondrial and microsatellite markers to explore the extent of introgressive hybridization between th...
Article
Helicolenus dactylopterus is an Atlantic benthopelagic fish species inhabiting high-energy habitats on continental slopes, seamounts and islands. Partial sequences of the mitochondrial control region (D-loop) and cytochrome b (cyt b) were used to test the hypothesis that H. dactylopterus disperses between continental margin, island and seamount hab...
Article
Full-text available
The tenet that ecological adaptation can lead to recurrent eco-morphological trends resulting from repetitive processes has long been a primary topic of investigation in evolutionary ecology. To explore this aspect further, this study provides an analysis of the morphological diversity in chondrostoms (Cyprinidae). This freshwater fish group shows...

To explore this aspect further, this study provides an analysis of the morphological diversity in chondrostoms (Cyprinidae). This freshwater fish group shows a...
Article
The phylogeography of Iberian freshwater fish species strongly reflects the geomorphological history of Iberian water drainages and formation of mountain ranges. In particular, the Iberian Central Massif limits two ichthyogeographical districts based on fish distribution assemblages: the Northwest district, which comprises all river basins north of...
Article
Interplay between the complex geography, hydrogeomorphological history, past climatic changes, and anthropogenic pressures is likely responsible for the current diversity and species' distribution of freshwater fishes in the Iberian Peninsula. To further disentangle the evolutionary processes promoting the diversification of endemic Iberian Cyprini...

ABOIM 2004. Annotated list of fishes caught by the R/V ARQUIPÉLAGO off the Cape Verde archipelago. Arquipélago. Life and Marine Sciences 21A: 57-71. A prospective survey was carried out in October-November of 2000, in the Cape Verde archipelago, by the R/V ARQUIPÉLAGO. The main objective was to determine the species composition and relative abundan...
