The threats facing Ecuador's Yasuní National Park are emblematic of those confronting the greater western Amazon, one world's last high-biodiversity wilderness areas. Notably, country's second largest untapped oil reserves--called "ITT"--lie beneath an intact, remote section park. conservation significance may weigh heavily in upcoming state-level and international decisions, including whether to develop or invest alternatives.
Abstract Systematic assessments of species extinction risk at regular intervals are necessary for informing conservation action 1,2 . Ongoing developments in taxonomy, threatening processes and research further underscore the need reassessment 3,4 Here we report findings second Global Amphibian Assessment, evaluating 8,011 International Union Conservation Nature Red List Threatened Species. We find that amphibians most threatened vertebrate class (40.7% globally threatened). The updated...
Comprehensive assessments of species' extinction risks have documented the crisis1 and underpinned strategies for reducing those risks2. Global reveal that, among tetrapods, 40.7% amphibians, 25.4% mammals 13.6% birds are threatened with extinction3. Because global been lacking, reptiles omitted from conservation-prioritization analyses that encompass other tetrapods4-7. Reptiles unusually diverse in arid regions, suggesting they may different conservation needs6. Here we provide a...
Accurate and detailed species distribution maps are fundamental for documenting interpreting biological diversity. For snakes, an ecologically diverse group of reptiles, syntheses data on patterns remain scarce. We present the first comprehensive collection detailed, voucher-based, point-locality, range all described documented Brazilian with major aim mitigating Wallacean shortfall as a contribution towards better understanding this rich, threatened, poorly studied megadiverse fauna....
Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense also affects tolerance to abiotic stressors. Urban-rural gradients associated with the of clines 47% throughout world. Variation strength was explained changes drought stress and vegetation cover varied...
Ecuador is one of the most biodiverse countries in world, but faces severe pressures and threats to its natural ecosystems. Numerous species have declined require be objectively evaluated quantified, as a step towards development conservation strategies. Herein, we present an updated National Red List Assessment for amphibian Ecuador, with detailed complete coverages any Ecuadorian taxonomic group date. Based on standardized methodologies that integrate work, spatial analyses, ecological...
Abstract Visual systems adapt to different light environments through several avenues including optical changes the eye and neurological in how signals are processed interpreted. Spectral sensitivity can evolve via visual pigments housed retinal photoreceptors gene duplication loss, differential coexpression, sequence evolution. Frogs provide an excellent, yet understudied, system for evolution research due their diversity of ecologies (including biphasic aquatic-terrestrial life cycles)...
Anurans of the family Centrolenidae are a diverse clade arboreal frogs distributed across tropical America. Knowledge their taxonomy, systematics, ecology, behavior, morphology, and other evolutionary aspects biology is deficient. Relationships among centrolenid species remain largely unresolved, with no satisfactory phylogenetic hypothesis, none current genera has compelling evidence monophyly. Further, understanding phylogeny glassfrogs constrained by species-level taxonomic problems,...
Abstract Motivation We generated a novel database of Neotropical snakes (one the world's richest herpetofauna) combining most comprehensive, manually compiled distribution dataset with publicly available data. assess, for first time, diversity patterns all as well sampling density and biases. Main types variables contained three databases species occurrences: downloaded from Global Biodiversity Information Facility (GBIF), verified built through taxonomic work specialized literature,...
Glassfrogs (family: Centrolenidae) represent a fantastic radiation (~150 described species) of Neotropical anurans that originated in South America and dispersed into Central America. In this study, we review the systematics Ecuadorian glassfrogs, providing species accounts all 60 species, including three new herein. For provide information on evolution, morphology, biology, conservation, distribution. We present molecular phylogeny for Centrolenidae address cryptic diversity within family....
We describe a new species of Pristimantis from southern Ecuador, province Zamora Chinchipe. The is closely related to an undescribed Reserva Tapichalaca, Ecuador and with clade historically assigned the P. unistrigatus group, such as parvillus, luteolateralis, walkeri, among others. miniaturized frog (females 17.11.1 mm; males 13.20.9 mm), characterized by presence -shaped scapular folds, two subconical tubercles on medial posterior regions folds; tympanic membrane annulus present but not...
<title>Abstract</title> Islands offer invaluable opportunities for studying evolutionary processes due to their isolation and distinct environmental conditions. The Galapagos Islands, renowned rich biodiversity, host several endemic gecko species of the genus <italic>Phyllodactylus</italic> (Gekkota: Phyllodactylidae). Despite importance derived from specialized adaptations crucial role in maintaining ecosystem balance, few studies have been conducted on these geckos. This highlights need...
Abstract Land use changes can have morphological and physiological impacts on wildlife. This study aimed to explore the influence of anthropogenic land morphology corticosterone concentrations in two songbirds endemic Galapagos archipelago: granivorous Small Ground Finch Geospiza fuliginosa insectivorous Yellow Warbler Setophaga petechia aureola San Cristobal Island. Birds were caught measured between June August 2018 July 2019 across four areas with different human uses: urban green coastal...
This study investigated geographic variation in a suite of reproductive behavioral traits Hyalinobatrachium fleischmanni across several sites Mexico and Ecuador. We made observations on the frequency egg-mass brooding behavior compared encounter rates between wet dry forest types. Brooding were significantly higher drier region, suggesting potential relationship paternal care climatic conditions. also calling oviposition regions tested for associations with distributional range frog-eating...
A molecular phylogeny of the Neotropical snail-eating snakes (tribe Dipsadini) is presented including 43 (24 for first time) 77 species, sampled both nuclear and mitochondrial genes. Morphological phylogenetic support was found four new species Dipsas one Sibon , which are described here based on their unique combination molecular, meristic, color pattern characteristics. Sibynomorphus designated as a junior subjective synonym . Dipsaslatifrontalis D.palmeri resurrected from synonymy...

Fast and accurate taxonomic identification of invasive trans-located ladybird beetle species is essential to prevent significant impacts on biological communities, ecosystem functions, agricultural business economics. Therefore, in this work we propose a two-step automatic detector for beetles random environment images as the first stage towards an automated classification system. First, image processing module composed saliency map representation, simple linear iterative clustering...
Abstract Geographical barriers like mountain ranges impede genetic exchange among populations, promoting diversification. The effectiveness of these in limiting gene flow varies between lineages due to each species' dispersal modes and capacities. Our understanding how the Andes orogeny contributes species diversification comes from well‐studied vertebrates a few arthropods plants, neglecting organisms unable fly or walk long distances. Some arachnids, such as Gasteracantha cancriformis ,...
