[dynamics of the intensity of respiration in early embryogenesis of amphibians].we studied growth and respiration rate during early ontogenesis of the axolotl ambystoma mexicanum, bosca's newt triturus waltlii, the green toad bufo viridis, and the smooth clawed frog xenopus laevis. the respiration rate in these amphibian species increases during embryonal and larval development, peaks after transition to active feeding, and decreases at later stages of ontogenesis. the patterns of dynamics of this energy metabolism index in tailed and tailless amphibians have some differenc ...200011036669
exotic fish in exotic plantations: a multi-scale approach to understand amphibian occurrence in the mediterranean region.globally, amphibian populations are threatened by a diverse range of factors including habitat destruction and alteration. forestry practices have been linked with low diversity and abundance of amphibians. the effect of exotic eucalyptus spp. plantations on amphibian communities has been studied in a number of biodiversity hotspots, but little is known of its impact in the mediterranean region. here, we identify the environmental factors influencing the presence of six species of amphibians (th ...201526061096
sensitivity and behavior of the iberian newt, triturus boscai, under terrestrial exposure to ammonium nitrate. 200516400545
mitochondrial dna phylogeography of lissotriton boscai (caudata, salamandridae): evidence for old, multiple refugia in an iberian endemic.in europe, southern peninsulas served as refugia during cold periods in the pleistocene, acting both as centres of origin of endemisms and as sources from which formerly glaciated areas were recolonized during interglacial periods. previous studies have revealed that within the main refugial areas, intraspecific lineages often survived in allopatric refugia. we analysed two mitochondrial markers (nad4, control region, approximately 1.4 kb) in 103 individuals representing the entire distribution ...200616968276
alteration of courtship behavior because of water acidification and minor effect of ammonium nitrate in the iberian newt (lissotriton boscai).although many studies have assessed the effects of water pollution on amphibians, few have focused on the alteration of vital behaviors. newt species usually display complex courtship behavior that may be altered by sublethal levels of contaminants. we analyzed the effects of ammonium nitrate and water acidification on courtship behavior of the iberian newt (lissotriton boscai). we exposed newt couples to three treatments (control, nominal 90 mg n--no3nh4/l, and nominal ph 4) and recorded the oc ...200919220079
de novo transcriptome assembly and polymorphism detection in two highly divergent evolutionary units of bosca's newt (lissotriton boscai) endemic to the iberian peninsula.this article reports the de novo transcriptome assemblies of two highly divergent evolutionary units of the iberian endemic bosca's newt, lissotriton boscai. these two units are distributed mostly allopatrically but overlap in the central-southwestern coastal region of portugal. the resources we provide include the raw sequence reads, the assembled transcripts, the annotation and snps called for both lineages.201727470435
pigmentation plasticity enhances crypsis in larval newts: associated metabolic cost and background choice behaviour.in heterogeneous environments, the capacity for colour change can be a valuable adaptation enhancing crypsis against predators. alternatively, organisms might achieve concealment by evolving preferences for backgrounds that match their visual traits, thus avoiding the costs of plasticity. here we examined the degree of plasticity in pigmentation of newt larvae (lissotriton boscai) in relation to predation risk. furthermore, we tested for associated metabolic costs and pigmentation-dependent back ...201728051112
discordant patterns of introgression across a narrow hybrid zone between two cryptic lineages of an iberian endemic newt.the study of natural hybrid zones can illuminate aspects of lineage divergence and speciation in morphologically cryptic taxa. we studied a hybrid zone between two highly divergent but morphologically similar lineages (south-western and south-eastern) of the iberian endemic bosca's newt (lissotriton boscai) in sw iberia with a multilocus dataset (microsatellites, nuclear and mitochondrial genes). structure and newhybrids analyses retrieved few admixed individuals, which classified as backcrosses ...202031677317
evolutionary history of lissotriton helveticus: multilocus assessment of ancestral vs. recent colonization of the iberian peninsula.the pleistocene was characterized by climatic changes that greatly altered the distribution of organisms. population extinctions, bottlenecks, isolation, range expansions and contractions were often associated with glaciations, leaving signatures in the spatial patterns of genetic diversity across species. lissotriton helveticus belongs to a pan-european lineage of newts that were strongly affected by glaciations and represent an excellent model to analyse the effect of generalized climatic chan ...201121530664
high pathogen prevalence in an amphibian and reptile assemblage at a site with risk factors for dispersal in galicia, spain.ranaviruses are agents of disease, mortality and population declines in ectothermic vertebrates and emergences have been repeatedly linked to human activities. ranaviruses in the common midwife toad ranavirus lineage are emerging in europe. they are known to be severe multi-host pathogens of amphibians and can also cause disease in reptiles. recurrent outbreaks of ranavirus disease and mortality affecting three species have occurred at a small reservoir in north-west spain but no data were avail ...202032730306

temporal changes in cutaneous bacterial communities of terrestrial- and aquatic-phase newts (amphibia).animal-associated bacterial communities play essential roles for their host's ecology, physiology and health. temporal dynamics of these communities are poorly understood, but might be of high relevance for amphibians with a well-expressed biphasic biology of adults where the structure of their skin changes drastically between the aquatic and terrestrial phases. here, we investigated the temporal dynamics of cutaneous bacterial communities of lissotriton boscai and triturus marmoratus by monthly ...201728419728
