Membrane-Bound Class III Peroxidases: Unexpected Enzymes with Exciting Functions
(MDPI, 2018-09-21)[Abstract] Class III peroxidases are heme-containing proteins of the secretory pathway with a high redundance and versatile functions. Many soluble peroxidases have been characterized in great detail, whereas only a few ... -
Mitogenome Phylogenetics in the Genus Palaemon (Crustacea: Decapoda) Sheds Light on Species Crypticism in the Rockpool Shrimp P. Elegans
(PLOS, 2020-08-18)[Abstract] The genus Palaemon comprises worldwide marine and freshwater shrimps and prawns, and some of them are ecologically or commercially important species. Palaemon is not currently a monophyletic group, so phylogenetics ... -
Molecular and evolutionary analysis of mussel histone genes ("Mytilus" spp.): possible evidence of an "orphon origin" for H1 histone genes
(Springer Nature, 2002-09)[Abstract:] Linker histones are a divergent group of histone proteins with an independent evolutionary history in which, besides somatic subtypes, tissue- and differentiation-specific subtypes are included. In the present ... -
Molecular evolutionary characterization of the mussel "Mytilus" histone multigene family: first record of a tandemly repeated unit of five histone genes containing an H1 subtype with orphon features
(Springer Nature, 2004-02)[Abstract] The present work represents the first characterization of a clustered histone repetitive unit containing an H1 gene in a bivalve mollusk. To complete the knowledge on the evolutionary history of the histone ... -
Molecular organization and phylogenetic analysis of 5S rDNA in crustaceans of the genus "Pollicipes" reveal birth-and-death evolution and strong purifying selection
(BioMed Central, 2011-10-17)[Abstract] Background: The 5S ribosomal DNA (5S rDNA) is organized in tandem arrays with repeat units that consist of a transcribing region (5S) and a variable nontranscribed spacer (NTS), in higher eukaryotes. Until ... -
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, ... -
