Evolutionary history of lamprey paired species Lampetra fluviatilis (L.) and Lampetra planeri (Bloch) as inferred from mitochondrial DNA variation
A remarkable trend in the evolution of lampreys is the occurrence in most genera of ‘paired species’, in which the parasitic anadromous lampreys are believed to have given rise to nonparasitic… Expand
Lampreys of the Iberian Peninsula: distribution, population status and conservation
The 3 lamprey species, sea lamprey Petromyzon marinus L., European river lamprey Lampetra fluviatilis L. and European brook lamprey L. planeri Bloch, that inhabit the Iberian Peninsula are of… Expand
A Ranking System for Reference Libraries of DNA Barcodes: Application to Marine Fish Species from Portugal
Background The increasing availability of reference libraries of DNA barcodes (RLDB) offers the opportunity to the screen the level of consistency in DNA barcode data among libraries, in order to… Expand
The genetics of maintenance of an all-male lineage in the Squalius alburnoides complex
Squalius alburnoides is a complex of minnows common to the Iberian Peninsula, consisting of two distinct forms. The most common form is comprised of diploid and polyploid asexual hybrids heterozygous… Expand
Strong genome-wide divergence between sympatric European river and brook lampreys
Lampreys, together with hagfishes, are the only extant representatives of jawless vertebrates and thus of prime interest for the study of vertebrate evolution . Most lamprey genera occur in two… Expand
Diversity in the Reproductive Modes of Females of the Rutilus alburnoides Complex (Teleostei, Cyprinidae): A Way to Avoid the Genetic Constraints of Uniparentalism
Effects of an extreme flash flood on the native fish assemblages across a Mediterranean catchment
Abstract The effects of an extreme flash flood on the native fish assemblages across a Mediterranean catchment in Southwest Portugal were investigated. The fish community structure and habitat were… Expand
Paralog-specific primers for the amplification of nuclear Loci in tetraploid barbels (barbus: cypriniformes).
Thirty paralog-specific primers were developed, following an intron-primed exon-crossing strategy, for S7 and growth hormone genes in Barbus (subgenera Barbus and Luciobarbus). We found that… Expand

The karyotype of the endangered fish Anaecypris hispanica was revisited using advanced cytogenetic techniques to elucidate its putative relationship with the paternal ancestor of the hybrid complex… Expand
EXPLOITATION AND CONSERVATION OF ECHINODERMS
The phylum Echinodermata contains some of the most charismatic benthic marine invertebrates and has become a symbol of marine life. However, growing global pressures on the collection of echinoderms… Expand
