The European spiny lobster (Palinurus elephas) is a suitable model organism to study the effects of past history and current oceanographic processes on the genetic diversity and population structure of marine species with a long-lived larval phase. A portion of the COI gene was sequenced in 227 individuals from 11 localities, covering most of the present(More)
> Abstract The order Decapoda represents a species-rich group of crustaceans. Numerous economically important and morphologically diverse members of this group have been studied extensively for many decades, in part to understand their phylogeny. There are several competing hypotheses concerning relationships among the major lineages of Decapoda. Our(More)
Molecular data can aid in the resolution of conflicting hypotheses generated through difficulties in the interpretation of morphological data and/or an incomplete fossil record. Moreover, the reconstruction of phylogenetic relationships using molecular data may help to trace back the origin of morphological innovations which had a major impact on the(More)
Lobsters are a ubiquitous and economically important group of decapod crustaceans that include the infraorders Polychelida, Glypheidea, Astacidea and Achelata. They include familiar forms such as the spiny, slipper, clawed lobsters and crayfish and unfamiliar forms such as the deep-sea and "living fossil" species. The high degree of morphological diversity(More)
Porcine teschoviruses (PTVs) have been previously shown to be the most abundant cytopathic viruses found in swine feces. In the present study, the diversity of PTVs was studied, using PTV isolates collected between 2004 and 2009 in a wide territory in Spain. In order to characterize genetically the isolates, phylogeny reconstructions were made using maximum(More)
BACKGROUND Molecular tools may help to uncover closely related and still diverging species from a wide variety of taxa and provide insight into the mechanisms, pace and geography of marine speciation. There is a certain controversy on the phylogeography and speciation modes of species-groups with an Eastern Atlantic-Western Indian Ocean distribution, with(More)
Teschovirus and Sapelovirus are two genera of the Picornaviridae family, comprising highly variable and heterogeneous enteric viruses, commonly found in faecal samples from domestic pigs. Although both of them are also known to infect wild boar, studies on their presence in these wild suids are scarce. The present study aimed at determining the presence of(More)
Comparative multispecies studies allow contrasting the effect of past and present oceanographic processes on phylogeographic patterns. In the present study, a fragment of the COI gene was analyzed in seven decapod crustacean species from five families and with different bathymetric distributions. A total of 769 individuals were sampled along the(More)
Recombination is a pervasive process generating diversity in most viruses. It joins variants that arise independently within the same molecule, creating new opportunities for viruses to overcome selective pressures and to adapt to new environments and hosts. Consequently, the analysis of viral recombination attracts the interest of clinicians,(More)
The European spiny lobster (Palinurus elephas) mean annual catches have decreased alarmingly during recent decades along its entire distribution area due to stock over-exploitation, which makes it a primary target for conservation plans. A total of 164 microsatellite loci were isolated from a genomic library of P. elephas enriched for CA, GA, CAA and GATA(More)
