Origin and evolution of "Mytilus" mussel satellite DNAs
(Canadian Science Publishing, 2005-04)[Abstract] A phylogenetic reconstruction based on the amplification of 3 satellite DNAs (stDNAs) was carried out in 1 crustacean species and 15 bivalve species of the subclass Pteriomorphia (10, subfamily Mytilinae; 1, ... -
Pax Romana: ‘Refuge Abandonment’ and Spread of Fearless Behavior in a Reconciling World
(Wiley, 2019-02-05)[Abstract] Intense human persecution of wildlife in the past selected for shy individuals that survived in suboptimal refuge habitats. It appears that this long-term conflict is coming to an end in southern Europe, where ... -
Phenotypic and Environmental Correlates of Natal Dispersal Movements in Fragmented Landscapes
(Springer, 2022)[Abstract] Context Natal dispersal critically influences eco-evolutionary dynamics and the persistence of spatially structured populations. As both short- and long-distance movements contribute to population persistence ... -
Phytochemical Assessment of Native Ecuadorian Peppers (Capsicum spp.) and Correlation Analysis to Fruit Phenomics
(MDPI, 2020-08-04)[Abstract] In this work, the impact of pepper (Capsicum spp.) fruits morphology on their composition for health-promoting compounds was investigated. For that purpose, pepper accessions from Ecuador, one of the hotspots ... -
Polyploidy in a Natural Population of Mussel, Mytilus Trossulus
(Canadian Science Publishing, 2000-03)[Abstract] We have analyzed natural polyploidy in a population of “Mytilus trossulus” from Vancouver Island (British Columbia, Canada) by means of cytogenetic techniques. Results obtained are the first reporting on this ... -
Population genetic analysis of "Ensis directus" unveils high genetic variation in the introduced range and reveals a new species from the NW Atlantic
(Springer Nature, 2012-07-31)[Abstract] We report current genetic variation of populations of the razor shell Ensis directus (Conrad 1843) (Mollusca: Bivalvia: Pharidae) in native (North American) and introduced (European) ranges using nuclear and ... -
Predator-Prey Collapses at the Edge of Predator Distribution: The Case of Clupeids and Common Guillemots (Uria aalge) in NW Iberia
(CSIC, 2023-02-23)[Abstract] The spatial structuring of seabird populations makes individual colonies very dependent on regional factors. That is especially the case in small edge populations located far from large colonies. We analysed ... -
Rapid Colour Shift by Reproductive Character Displacement in Cupido Butterflies
(Wiley, 2020-10-13)[Abstract] Reproductive character displacement occurs when competition for successful breeding imposes a divergent selection on the interacting species, causing a divergence of reproductive traits. Here, we show that a ... -
Response of Diverse Peanut Cultivars to Nano and Conventional Calcium Forms under Alkaline Sandy Soil
(MDPI, 2023-07-09)[Abstract] Calcium is one of the most limiting factors for the growth and reproduction of peanut, which ultimately affects pod and seed yields. A two-year field experiment was carried out to assess the impact of five calcium ... -
Species delimitation and DNA barcoding of Atlantic Ensis (Bivalvia, Pharidae)
(Wiley, 2013-09-03)[Abstract] Ensis Schumacher, 1817 razor shells occur at both sides of the Atlantic and along the Pacific coasts of tropical west America, Peru, and Chile. Many of them are marketed in various regions. However, the absence ... -
Stick Supply to Nests by Cliff-Nesting Raptors as an Evolutionary Load of Past Tree-Nesting
(Queen's University, 2019)[Abstract] The supply of sticks to cliff nests by many European raptors has been explained only as a functional means of decreasing ectoparasite loads in nests and for signalling nest occupancy. We provide here a historical ... -
Systematic analysis and evolution of 5S ribosomal DNA in metazoans
(Springer Nature, 2013-07-10)[Abstract] Several studies on 5S ribosomal DNA (5S rDNA) have been focused on a subset of the following features in mostly one organism: number of copies, pseudogenes, secondary structure, promoter and terminator ... -
Telomeric localization of the vertebrate-type hexamer repeat, (TTAGGG) ₙ, in the wedgeshell clam "Donax trunculus" and other marine invertebrate genomes
(American Society for Biochemistry and Molecular Biology, 2002-05-31)[Abstract]: The hexamer repeat sequence (TTAGGG) n, found at the ends of all vertebrate chromosomes, was previously identified as the main building element of one member of aHindIII satellite DNA family characterized in ... -
Temporal genetic variation of microsatellite markers in the razor clam "Ensis arcuatus" (Bivalvia: Pharidae)
(Cambridge University Press, 2009-12)[Abstract] The aim of this study was to characterize new microsatellite loci in the razor clam Ensis arcuatus (Bivalvia: Pharidae) and examine the temporal genetic variability of a natural bed in Cies Islands (Galicia, ... -
The 5S rDNA gene family in mollusks: characterization of transcriptional regulatory regions, prediction of secondary structures, and long-term evolution, with special attention to Mytilidae mussels
(Oxford University Press, 2011-07-01)[Abstract] Several reports on the characterization of 5S ribosomal DNA (5S rDNA) in various animal groups have been published to date, but there is a lack of studies analyzing this gene family in a much broader context. ... -
The linked units of 5S rDNA and U1 snDNA of razor shells (Mollusca: Bivalvia: Pharidae)
(Nature, 2011-08)[Abstract] The linkage between 5S ribosomal DNA and other multigene families has been detected in many eukaryote lineages, but whether it provides any selective advantage remains unclear. In this work, we report the ... -
The Selection of Anthropogenic Habitat by Wildlife as an Ecological Consequence of Rural Exodus: Empirical Examples From Spain
(Museu de Ciències Naturals de Barcelona, 2021-06-18)[Abstract] The increasing urbanization of the landscape is a major component of global change worldwide. However, it is puzzling that wildlife is selecting anthropogenic habitats despite the availability of apparently ... -
Toward Reliable Population Estimates of Wolves by Combining Spatial Cap-ture-Recapture Models and Non-invasive DNA Monitoring
(Springer Nature, 2018-02-01)[Abstract]: Decision-makers in wildlife policy require reliable population size estimates to justify interventions, to build acceptance and support in their decisions and, ultimately, to build trust in managing authorities. ... -
Tracing Back the History of Pepper (Capsicum annuum) in the Iberian Peninsula from a Phenomics Point of View
(MDPI, 2022-11-13)[Abstract] The Iberian Peninsula was the place where pepper (Capsicum annuum) entered Europe and dispersed to other continents but was also an important secondary center for its diversification. The current work evaluated ... -
Translocation in Relict Shy-Selected Animal Populations: Program Success Versus Prevention of Wildlife-Human Conflict
(Elsevier, 2022-03-11)[Abstract] Past human persecution of wildlife has acted as a major selection agent shaping many animal features including behaviour. A major component of behaviour with diverse consequences for conservation is the ...
