Introduction
My background in the MNCN-CSIC started studing morphological characters of different seastars of the genus Asterina.
My current research studies, in population genetics, include developing microsatellites and gene fragments of several marine species as mollusks and corals. Studying gene flow, phylogenetic relationships, genetic structure in order to know connectivity among populations.

Population connectivity studies are a useful tool for species management and conservation planning, particular of highly threatened or endangered species. Here, we evaluated the genetic structure and connectivity pattern of the endangered coral Cladocora caespitosa across its entire distribution range in the Mediterranean Sea. Additionally, we exam...
Oceanographic features such as currents, waves, temperature, and salinity, together with life history traits, control patterns and rates of gene flow and contribute to shaping the population genetic structure of marine organisms. Seascape genetics is an emerging discipline that adopts a spatially‐explicit approach to examine biotic and abiotic fact...
We analysed the patterns of genetic variability of eastern Mediterranean populations of the scleractinian coral Cladocora caespitosa, from the Aegean and Levantine seas, using 19 polymorphic microsatellite loci, 11 of which were newly characterized. The observed genetic pattern reflects a scenario of isolation by environment: FST comparisons showed...
Declines in Panulirus echinatus Smith, 1869 populations along their wide distribution in the Atlantic Ocean have spurred efforts to improve their fisheries management and conservation. In this study, the genetic structure of these populations is reported for the first time. In a survey of 18 species‐specific polymorphic microsatellite markers, 152...
Context
Spatially heterogeneous oceanographic properties such as currents, waves, and biogeochemical gradients control the movement of gametes and larvae of marine species. However, it is poorly understood how such spatial dynamics may shape the genetic connectivity, diversity, and structure of marine populations.
Objectives
We applied a seascape...
Genetic connectivity studies are essential to understand species diversity and genetic structure and to assess the role of potential factors affecting connectivity, thus enabling sound management and conservation strategies. Here, we analyzed the patterns of genetic variability in the marine snail Gibbula divaricata from five coastal locations in t...
Dendropoma petraeum, considered the primary vermetid reef-building species in the Mediterranean, has recently been shown to be a species complex of at least four cryptic species. These species have highly restricted, non-overlapping distributions, causing concern for their conservation status. To better study the genetic diversity of these populati...
Three species of the genus Asterina are known to inhabit the Mediterranean Sea and the north-eastern Atlantic Ocean: Asterina gibbosa (Pennant, 1777), A. pancerii (Gasco, 1870) and A. phylactica Emson & Crump, 1979. Differentiation of these species has primarily been based only on subtle characters (some highly debatable), such as colour or size. T...
This volume contains the main results of the EC FP7 “The Ocean of Tomorrow” Project CoCoNet, divided in two
sections: 1) a set of guidelines to design networks of Marine Protected Areas in the Mediterranean and the Black Seas; 2) a smart wind chart that will allow evaluating the possibility of installing Offshore Wind Farms in both seas. The concep...
In the present study we used the high-throughput sequencing technology Illumina MiSeq to develop 26 polymorphic microsatellite loci for the marine snail
Gibbula divaricata
. Four to 32 alleles were detected per locus across 30 samples analyzed. Observed and expected heterozygosities ranged from 0.130 to 0.933 and from 0.294 to 0.956, respectively....

Microsatellite loci (26 in total) were isolated
for the first time for the entocommensal nemertean Malacobdella
arrokeana, using 454 GS-FLX Titanium pyrosequencing.
We developed conditions for amplifying these markers in 8 multiplex and 5 individual reactions. One to 14 alleles were detected per locus across 25 samples analyzed from San Matı´as Gul...
This article documents the addition of 83 microsatellite marker loci and 96 pairs of single-nucleotide polymorphism (SNP) sequencing primers to the Molecular Ecology Resources Database. Loci were developed for the following species: Bembidion lampros, Inimicus japonicus, Lymnaea stagnalis, Panopea abbreviata, Pentadesma butyracea, Sycoscapter hirti...

Panulirus echinatus from Canary Archipelago population has undergone a drastic decline in the last decades and this specie is currently included as ‘‘In danger of extinction’’ in the archipelago. This project is intended to evaluate genetic population structure and create tools for conservation management for this specie in all different islands that was habitat for P. echinatus.
