Introduction
My research interests are based on the management, conservation and evolution of aquatic organisms, mainly fishes and molluscs. I have expertise on phylogenetic relationships, studies of genetic variability in wild populations and the effect of the different evolutionary forces driving the distribution of this variability.

European flat oyster (Ostrea edulis) is an ecologically and economically important marine bivalve, that has been severely affected by the intracellular parasite Bonamia ostreae. In this study, a flat oyster SNP array (~14,000 SNPs) was used to validate previously reported outlier loci for divergent selection associated with B. ostreae exposure in t...

In this study, we quantified the three key biological processes, growth, recruitment, and dispersal pattern, which are necessary for a better understanding of the population dynamics of the blue and red shrimp Aristeus antennatus. This marine exploited crustacean shows sex-related distribution along the water column, being females predominate in th...
Article
Full-text available
The blue and red shrimp Aristeus antennatus has been intensively exploited by trawling fishery in the Western Mediterranean Sea. Implementation of an adequate management plan needs complete genetic data of the non-spawning and spawning grounds of the species. During the reproductive period, the species forms spawning aggregations in the middle slop...

The population biology of the deep-sea shrimp Aristeus antennatus, as with other exploited demersal species, is usually studied using data from fishery statistics. Such statistical analyses have shown female-biased sex ratios during the spawning season in this species. Because the abundance of males increases at greater depths that are not exploite...

The maintenance of biological diversity at ecosystem, species and intraspecific levels is essential to ensure the survival of forests. The palaeartic yew Taxus baccata is part of a number of threatened forest types with prioritized conservation value in Europe. We investigated the spatial distribution of microsatellite genetic diversity in forty-si...

The impact of escapees from aquaculture is of general concern for the sustainability of natural resources. Turbot Scophthalmus maximus is a marine flatfish of great commercial value whose land-based aquaculture started approx. 40 yr ago; hence, a low impact of escapees is expected on wild populations. However, enhancement of wild stocks using farme...

Spanish National Parks (PNs), due to their ecological, educative and research value are areas of special interest for conservation issues. Currently, there are two different Marine National Parks in Spain (Islas Atlánticas, PNIA; Archipiélago de Cabrera, PNAC). The aim of the present study was the analysis of distribution, phylogenetic relationship...

Productivity traits, such as prolificacy, are of high importance in livestock species. These traits depend basically on many environmental and genetic factors. In sheep, some genes (mainly belonging to the transforming growth factor β genes superfamily) have an important effect on prolificacy, where the bone morphogenetic factor 15 (BMP15, also nam...

1. Brown trout (Salmo trutta) is an important conservation resource in the Iberian Peninsula. The Atlantic is considered the most hydrologically stable region for the species, although inner Galicia (NW Spain) shows Mediterranean (unstable) climatic conditions. The Galician region, threatened by past releases of brown trout individuals from central...
Chapter
The survival of populations in several glacial refuges allowed the accumulation of genetic differences, the apparition of ancestral divergent lineages and ultimately promoted speciation. As a consequence, high genetic richness is common in extant brown trout populations from southern Europe. In the Iberian Peninsula, as many as four ancient mitocho...

The American mosquitofish, Gambusia holbrooki, is a worldwide invasive species. Multiple paternity might contribute to the invasive success of this species, by locally increasing effective population size. Using microsatellite loci, we examined multiple paternity of mosquitofish in Spanish basins. The percentage of gravid females that mated multipl...

Since the end of the 20th century, some headwaters of rivers in the eastern Pyrenees have been designated as genetic refuges to protect remaining native brown trout (Salmo trutta) diversity. The declaration was based on limited or no evidence of genetic impact from released non-native Atlantic hatchery fish. Hatchery releases were completely banned...

The crucial step of most of the current genetic studies is the extraction of DNA with sufficient quantity and quality. Several genomic DNA isolation methods have been described to successfully obtain male DNA from shrimp species. However, all current protocols require invasive handling methods on males for DNA isolation. Using Aristeus antennatus a...

Length polymorphism was observed in the mitochondrial DNA (mtDNA) control region (CR) of brown trout (Salmo trutta). Length variability was due to the presence of an 81 or 82 bp tandem duplication segment located in the 3′ hypervariable domain of the mtDNA CR in specimens from two European river basins, in the north-western Iberian Peninsula and in...
