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...
In the arid landscapes of Arabian Peninsula, high levels cryptic diversity among reptiles, and especially in geckos, have recently been revealed. Mountain ranges within peninsula were shown to contain highest richness reptile endemicity, serving as refugia species less adapted hyper-arid conditions lowlands. With up 19 endemic species, Hajar Mountains southeastern Arabia are a clear example this pattern. Owing its old geological history, complex topography geographic isolation from rest...
Complex social communication is expected to evolve whenever animals engage in many and varied interactions; that is, sociality should promote communicative complexity. Yet, informal comparisons among phylogenetically independent taxonomic groups seem cast doubt on the putative role of factors evolution complex communication. Here, we provide a formal test hypothesis alongside alternative explanations for We compiled data documenting variations signal complexity closely related species...
Abstract Aim To understand the patterns of genetic, geographical and morphological diversification in Arabian gecko subspecies Pristurus rupestris , to discuss various processes that generate shape diversity arid mountain ranges. Location Hajar Mountains, south‐eastern Peninsula. Methods We sampled 466 individuals across entire range P. r. Mountains sequenced one mitochondrial gene for all samples, extra four nuclear genes a subset 75 specimens. A total 155 were characterized...
Abstract Anuran amphibians undergo major morphological transitions during development, but the contribution of their markedly different life-history phases to macroevolution has rarely been analysed. Here we generate testable predictions for coupling versus uncoupling phenotypic evolution tadpole and adult phases, underlying expression genes related feature formation. We test these by combining evidence from gene in two distantly frogs, Xenopus laevis Mantidactylus betsileanus , with...
Abstract Ecological stoichiometry and studies of biogeochemical niches have mainly focused on plankton vascular plants, but the phenotypically closest modern relatives early bryophytes, been largely neglected. We analysed C:N:P stoichiometries elemental compositions (K, Na, Mg, Ca, S, Fe) 35 widely distributed bryophyte species inhabiting springs. estimated ratios their niches, investigated how elementomes respond to environment determined whether they tend diverge more for coexisting than...
Islands have long been recognized as key contributors to biodiversity because they facilitate geographic isolation and ecological divergence from mainland ancestors. However, island colonization has traditionally considered an evolutionary dead-end process, its consequences for continental remain understudied. Here, we use the radiation of Columbiformes (i.e. pigeons doves) examine if niche shifts on islands shaped biological diversification community composition continents. We show that by...
Abstract Biologists have long noted that endotherms tend to larger bodies (Bergmann’s rule) and shorter appendages (Allen’s in colder environments. Nevertheless, many taxonomic groups appear not conform these ‘rules’, general explanations for frequent exceptions are currently lacking. Here we note by combining complementary changes body extremity size, lineages could theoretically respond thermal gradients with smaller either trait than those predicted Bergmann’s or Allen’s rule alone. To...
A molecular phylogeny of the sphaerodactylid geckos genus Pristurus is inferred based on an alignment 1845 base pairs (bp) concatenated mitochondrial (12S) and nuclear (acm4, cmos, rag1 rag2) genes for 80 individuals, representing 18 23–26 species, three subspecies P. rupestris. The results indicate that rupestris polyphyletic includes two highly divergent clades: eastern clade, found in coastal Iran throughout Hajar Mountain range northern Oman UAE; western distributed from central Oman,...
In the present work, we use an exceptional database including 5,359 records of 101 species Oman's terrestrial reptiles together with spatial tools to infer patterns richness and endemicity, habitat preference each better define conservation priorities, especial focus on effectiveness protected areas in preserving this unique arid fauna. Our results indicate that sampling effort is not only remarkable from a taxonomic point view, multiple observations for most species, but also coverage...
The acquisition of key innovations and the invasion new areas constitute two major processes that facilitate ecological opportunity subsequent evolutionary diversification. Using a lizard radiation as model, Australasian diplodactyloid geckos, we explored effects (adhesive toepads snake-like phenotype) environments (island colonization) in promoting evolution phenotypic species diversity. We found no evidence had significantly increased diversification, which challenges common assumption has...
The existence of elaborate ornamental structures in males is often assumed to reflect the outcome female mate choice for showy males. However, appears weak many iguanian lizards, but still exhibit an array ornament-like around throat. We performed a phylogenetic comparative study assess whether these have originated response male-male competition or need improved signal efficiency visually difficult environments. found little evidence influence competition. Instead, forest species were more...
Abstract The processes that allow some lineages to diversify rapidly at a global scale remain poorly understood. Although earlier studies emphasized the importance of dispersal, expansions expose populations novel environments and may also require adaptation diversification across new niches. In this study, we investigated contributions these radiation crows ravens (genus Corvus ). Combining phylogeny with comprehensive phenotypic climatic data, show experienced massive expansion niche was...
Flying squirrels are the only group of gliding mammals with a remarkable diversity and wide geographical range. However, their evolutionary story is not well known. Thus far, identification extinct flying has been exclusively based on dental features, which, contrary to certain postcranial characters, unique them. Therefore, fossils attributed this clade may indeed belong other squirrel groups. Here we report oldest fossil skeleton (11.6 Ma) that displays gliding-related diagnostic features...
Island colonization is often assumed to trigger extreme levels of phenotypic diversification. Yet, empirical evidence suggests that it does not always so. In this study we test hypothesis using a completely sampled mainland-island system, the arid clade Hemidactylus, group geckos mainly distributed across Africa, Arabia and Socotra Archipelago. To such purpose, generated new molecular phylogeny on which mapped body size head proportions. We then explored whether island continental taxa...
Abstract Metabolomes, as chemical phenotypes of organisms, are likely not only shaped by the environment but also common ancestry. If this is case, we expect that closely related species pines will tend to reach similar metabolomic solutions same environmental stressors. We examined metabolomes two sympatric subspecies Pinus sylvestris in Sierra Nevada (southern Iberian Peninsula), summer and winter exposed folivory pine processionary moth. The overall differed between both tended respond...
Plants respond locally and systemically to herbivore attack. Most of the research conducted on plant-herbivore relationships at element molecular levels have focused elemental composition or/and certain compounds or specific families defence metabolites showing that herbivores tend select plant individuals species with higher nutrient concentrations avoid those compounds. We performed stoichiometric metabolomics, both local systemic, analyses in two subspecies Pinus sylvestris under attack...
Abstract Mosses are amongst the oldest and simplest plants, they can be found almost everywhere in world, condition structure function of many ecosystems. Their sensitivity to environmental changes makes them very interesting subjects study ecology, understanding provide insights into evolutionary history plants. However, moss traits their relationship with environment is far behind that vascular We sampled 303 assemblages aquatic semi‐aquatic (hygrophytic) mosses growing semi‐natural...
