Climatic conditions changing over time and space shape the evolution of organisms at multiple levels, including temperate lizards in family Lacertidae. Here we reconstruct a dated phylogenetic tree 262 lacertid species based on supermatrix relying novel phylogenomic datasets fossil calibrations. Diversification lacertids was accompanied by an increasing disparity among occupied bioclimatic niches, especially last 10 Ma, during period progressive global cooling. Temperate also underwent...
Faunal turnover in Indo-Australia across Wallace's Line is one of the most recognizable patterns biogeography and has catalyzed debate about role evolutionary geoclimatic history biotic interchanges. Here, analysis more than 20,000 vertebrate species with a model geoclimate biological diversification shows that broad precipitation tolerance dispersal ability were key for exchange deep-time gradient spanning region. Sundanian (Southeast Asian) lineages evolved climate similar to humid...
Abstract Aim Squamate fitness is affected by body temperature, which in turn influenced environmental temperatures and, many species, exposure to solar radiation. The biophysical drivers of temperature have been widely studied, but we lack an integrative synthesis actual experienced the field, and their relationships temperatures, across phylogeny, behaviour climate. Location Global (25 countries on six continents). Taxa Squamates (210 representing 25 families). Methods We measured 20,231...
The genus Karyolysus was originally proposed to accommodate blood parasites of lacertid lizards in Western Europe. However, recent phylogenetic analyses suggested an inconclusive taxonomic position these the order Adeleorina based on available genetic information. Inconsistencies between molecular phylogeny, morphology, and/or life cycles can reflect lack enough information target group. We therefore surveyed 28 localities and collected samples from 828 23 species including lacertids,...
Abstract Background The movement and spatial ecology of an animal depends on its morphological functional adaptations to environment. In fossorial animals, the underground life help face peculiar ecological challenges, very different from those epigeal species, but may constrain their ability. Methods We made a long-term capture-recapture study strictly amphisbaenian reptile Trogonophis wiegmanni analyze patterns. also used passive integrated transponder (PIT) telemetry detect follow...
Mechanisms affecting consistent interindividual behavioral variation (i.e., animal personality) are of wide scientific interest. In poikilotherms, ambient temperature is one the most important environmental factors with a direct link to variety fitness-related traits. Recent empirical evidence suggests that individual differences in boldness linked thermoregulation strategy heliothermic species, as individuals regularly exposed predators during basking. Here, we tested for links between...
Abstract Aim To understand how the activity budgets of ectotherms vary in mountain areas with high microclimatic and habitat heterogeneity, these factors together modulate assemblage ectotherm communities. Location Tajzara Basin, Cordillera de Sama (3,600–4,300 m a.s.l.), Department Tarija, Bolivia. Taxon Four lizard species genus Liolaemus . Methods After parameterizing thermal physiology each recording operative temperature time series dataloggers, we calculated for every across 30...
Female and male hosts may maximise their fitness by evolving different strategies to compensate for the costs of parasite infections. The resulting sexual dimorphism might be apparent in differential relationships between load body condition, potentially reflecting differences energy allocation anti-parasitic defences. For example, lacertids with high condition produce many offspring while being intensely parasitised. In contrast, female show a outcome trade-offs immunity, aiming better...
Abstract Assembly of ecological communities is important for the conservation ecosystems, predicting perturbation impacts, and understanding origin loss biodiversity. We tested how amphibian are assembled by neutral niche‐based mechanisms, such as habitat filtering. Species richness, β‐diversities, reproductive traits amphibians were evaluated at local scale in seven habitats different elevation disturbance levels Wisui Biological Station, Morona‐Santiago, Ecuador, on foothills Cordillera...
Short-legged, small, robust frogs of the family Craugastoridae present a remarkable beta-diversity in high Andes, their distributions being characterized by very degree micro-endemism to specific valleys. We used dataloggers study temperature and humidity conditions microhabitats several species genus Microkayla at three elevation belts: below, within, above altitudinal range distribution Bolivia. also conducted thermal physiology experiments on limited number individuals one these species....
O lagarto raro e endêmico da Bolívia Liolaemus fittkaui foi considerado extinto na localidade dos parátipos. Atualmente a espécie está classificada como Vulnerável. Discutimos credibilidade suposta paratipos, assim o evento de extinção relatado. As observações apresentadas evidenciam que distribuição L. é mais ampla do havia sido relatada, estendendo-se quase 100 km ao longo das regiões altas Cordilheira Tiraque (Províncias Chapare, Carrasco). A mantém populações em áreas seu habitat...
Narrow Orogenic Arcs (NOA) on Earth are oftenly biodiversity hotspots, where biogeographic evolution is influenced by tectonic forcing. However, the relationships between mechanisms intrinsic to NOA, landscape and speciation forming hotspots have not been dwelt with. Different inherent such as slab roll back, tearing, edge delamination, mantle upwelling flow around subducted slabs, basin archipelago migration volcanic arc growth drive a dynamic that fosters processes of dispersal...
Cannibalism is a recurrent behavior across the animal kingdom, with important ecological and evolutionary consequences due to its potential trade-offs on fitness of involved individuals demography dynamics. has been reported in eight species several phylogenetic lineages within Liolaemus, highly diverse genus Neotropical lizards. Within Liolaemus montanus series, two are eat juveniles captivity. We observed female orientalis, another L. series member, which had ingested juvenile own wild. As...
Current climate change-forced local extinctions of ectotherms in their warmer distribution limits have been linked to a reduction activity budgets by excess heat. However, species may be determined biotic interactions as well. We aimed understand the role thermal drivers limit cold-adapted mountain ectotherms, and colder partially sympatric thermophilous species.In southern slopes Sierra de Guadarrama, Madrid, Spain, (1800–2200 m asl), we collected data from surveys active individuals,...
Oviparity is the most widespread reproductive mode among reptiles. The South American genus Liolaemus contains both oviparous and viviparous species, latter generally dominating at high latitudes elevations. We report for first time evidence suggesting oviparity in variegatus, an Andean lizard endemic to Bolivia. record its presence elevations up 4,200 m on Cordillera de Tiraque, which highest localities lizards world. characterize content of oviductal aborted eggs structure shell eggs....
