Comparative studies of mortality in the wild are necessary to understand evolution aging; yet, ectothermic tetrapods underrepresented this comparative landscape, despite their suitability for testing evolutionary hypotheses. We present a study aging rates and longevity across tetrapod ectotherms, using data from 107 populations (77 species) nonavian reptiles amphibians. test hypotheses how thermoregulatory mode, environmental temperature, protective phenotypes, pace life history contribute...
The flat-headed frog, Barbourula busuangensis , is a poorly known, riverine species, endemic to the province of Palawan in Philippines. We applied capture-mark-recapture (CMR) methods follow individuals at two sites (Malbato and San Rafael) island Busuanga over 10 months 2022–2023. used passive internal transponders (PITs) mark adult subadults single-colored visual elastomers (VIEs) for cohorts juveniles. From total 196 frogs PIT-tagged Malbato 144 Rafael, we obtained overall recapture rates...
Abstract Aim To test the role of mountains as barriers to gene flow in co‐distributed taxa with different life history traits. Location Sierra de Guadarrama, Central Spain. Methods We used larval genotypes four amphibian species ( Epidalea calamita , Hyla molleri Pelophylax perezi and Pelobates cultripes ) sampled on northern southern slopes Guadarrama describe genetic structure F ST migration rates per generation, clustering algorithms resistance by elevation surfaces. also recorded...
Accurate characterization of genetic diversity is essential for understanding population demography, predicting future trends and implementing efficient conservation policies. For that purpose, molecular markers are routinely developed nonmodel species, but key questions regarding sampling design, such as calculation minimum sample sizes or the effect relatives in sample, often neglected. We used accumulation curves sibship analyses to explore how these 2 factors affect marker performance...
Abstract Aim To reconstruct the historical biogeography of Hyla molleri , a tree frog endemic to Eurosiberian and Mediterranean bioclimatic zones in Iberian Peninsula. Location Methods We used molecular data (mt DNA species‐specific, polymorphic microsatellite loci) species distribution modelling ( SDM ) from Last Interglacial LIG present characterize spatial patterns genetic diversity this assess their relationship with climatically favourable areas through time. Results Genetic is...
Telomere shortening with age has been documented in many organisms, but few studies have reported telomere length measurements amphibians, and no information is available for growth after metamorphosis, nor wild populations. We provide both cross-sectional longitudinal evidence of net attrition a amphibian population natterjack toads ( Epidalea calamita ). Based on age-estimation by skeletochronology qPCR the framework an individual-based monitoring programme, we confirmed recaptured males....
Abstract Natural breeding sites for amphibians are decreasing in quantity and quality temperate regions, resulting local extinctions increasing population fragmentation. Artificial water bodies (e.g., tanks or cattle troughs) can represent suitable reproductive habitats some amphibians, but demographic data required to assess this assumption. We evaluated the role of artificial persistence a species concern, common midwife toad, Alytes obstetricans (Laurenti, 1768), at regional scales....
Abstract The ratio of the effective number breeders ( N b ) to adult census size a ), / , approximates departure from standard capacity population maintain genetic diversity in one reproductive season. This information is relevant for assessing status, understanding evolutionary processes operating at local scales, and unraveling how life‐history traits affect these processes. However, our knowledge on ratios nature limited because estimation both parameters challenging. sibship frequency...
Sex-related differences in mortality are widespread the animal kingdom.Although studies have shown that sex determination systems might drive lifespan evolution, chromosome influence on aging rates not been investigated so far, likely due to an apparent lack of demographic data from clades including both XY (with heterogametic males) and ZW (heterogametic females) systems.Taking advantage a unique collection capture-recapture datasets amphibians, vertebrate group where repeatedly evolved...
Abstract Natural populations often persist at the landscape scale as metapopulations, with breeding units (subpopulations) experiencing temporal extinction and recolonization events. Important parameters to forecast population viability in these systems include ratio of effective number breeders ( N b ) total adults a migration rates among subpopulations. Here, we present results 10‐year integrative monitoring program metapopulation Iberian green frog Pelophylax perezi central Spain. We...
Robust assessment of functional connectivity in amphibian population networks is essential to address their global decline. The potential graph theory characterize among populations has already been confirmed, but the movement data on which modelled graphs rely are often scarce and inaccurate. While probabilistic methods that account for intraspecific variability dispersal better reflect biological reality connectivity, they must be informed by systematically recorded individual data,...
Abstract The plant-trade is among the main sources of accidental introduction alien biodiversity. This includes amphibians, although effective colonization pathways have rarely been reported except from tropical areas. We document discovery an established breeding population Catalonian midwife toad, Alytes almogavarii Arntzen and García-París, 1995, in a plant nursery Madrid (Central Spain), 400 km away its natural distribution. During surveys 2023 we found adults, juveniles, tadpoles,...
Information about demography and habitat use is key for the effective management of amphibian populations, because it basis long-term monitoring endangered species provides insights processes by which common thrive in heavily transformed habitats. A capture-mark-recapture study was performed on a population Perez’s frog (Pelophylax perezi) central Spain. The area includes three breeding sites at maximum distance 700 metres straight line. aim to obtain information demographic parameters,...
Abstract In the face of worldwide amphibian declines, integrative studies combining individual‐based information and genetic data represent a powerful approach to produce robust, reliable, comparable assessments demographic dynamics. The Iberian painted frog ( Discoglossus galganoi ) is endemic Spain Portugal shows decreasing population trends across its range, but few have attempted estimate census sizes or assess diversity in wild populations, little known about their reproductive biology....
Ample variation in body size is common vertebrates over extensive geographical distances, or isolated populations, where effective barriers may cause dwarfism gigantism. Here we study potential causes of extreme reduction continental populations amphibians within a short distance and the absence barriers. Natterjack toads Epidalea calamita Doñana National Park (Spain) experience up to 2.1‐fold difference mass as little 37 km. Studying six divergent size, tested for genetic isolation dwarf...
Abstract Assessing patterns of functional connectivity among amphibian demes is crucial to unravel their population dynamics and prevent isolation eventual extinction. Integrative studies based on direct (capture-mark-recapture) indirect (genetic) estimates dispersal provide robust, biologically realistic inferences structure connectivity, with applications for conservation efforts. We focused two pond-breeding amphibians contrasting life-history traits: the short-lived, semi-arboreal Hyla...
Adaptive divergence has long been a core topic in the field of evolutionary biology, with natural selection traditionally considered its only driver. Here we focus on ability matching habitat choice to generate population and reproductive isolation. This alternative mechanism considers that individuals choose their habitats based an evaluation ecological match between phenotype available environments, which subsequently limits gene flow. To test this, conducted experiments captive zebra...
Abstract Wetland ecosystems worldwide are threatened by habitat alteration, climate change and the introduction of invasive species, even within protected areas. Unravelling reliance sensitive wetland‐dwelling such as amphibians, on characteristics is thus essential to identify conservation targets. Here we assess distribution genetic diversity two strongly aquatic amphibians ( Pelophylax perezi Pleurodeles waltl ) in association with features across most extensive, wetland Iberian...
Trypanosoma commonly parasitizes anuran hosts but very few studies have investigated ecological relationships in multiparasitized amphibians. We analysed a sample of 29 adult Iberian green frogs (Pelophylax perezi) from monitored population central Spain and found that 28 these individuals (96.5%) were infected with blood parasites. The protozoa genera Lankesterella (Apicomplexa: Eimeriorina) (72.4%) (Euglenozoa: Trypanosomatida) (69%) had the highest prevalence, followed by an...
