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...
We describe a new species of Lynchius from the eastern montane forest southern Ecuador. also report occurrence L. parkeri in Ecuador, on paramos Yacuri National Park, near border with Peru. used morphological and genetic evidence for description parkeri. Phylogenetic analyses were carried out using both maximum likelihood Bayesian inference DNA sequences mitochondrial nuclear genes. The phylogeny shows that simmonsi is sister to clade composed remaining flavomaculatus. has prominent heavily...
Elachistocleis is a Neotropical genus of microhylid frogs with 18 species, most which occur east the Andes in South America. Here, we present new phylogeny Gastrophryninae and describe name species from southern Ecuador—the first to be found west also Ecuador. Our based on DNA sequences mitochondrial genes 12S rRNA, 16S COI, nuclear BDNF, cmyc2, H3A, 28S, SIA1, Tyr. araios sp. n., sister all other Elachistocleis. The finding this taxon highlights probability existence more Andes.
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...
We describe a new species of Anolis lizard from the Pacific slopes Andes southwestern Ecuador at elevations between 372–1,000 m. The belongs to Dactyloa clade and may be distinguished other by size, external anatomy, mitochondrial DNA divergence, dewlap color. Based on phylogenetic analyses nuclear sequence data, we found that is sister A. fraseri in composed primarily large Dactyloid species. known protected area southern Ecuador, Buenaventura Reserve, which suggests least some its...
Comparative phylogeography allow us to understand how shared historical circumstances have shaped the formation of lineages, by examining a broad spectrum co-distributed populations different taxa. However, these types studies are scarce in Neotropics, region that is characterized high diversity, complex geology, and poorly understood biogeography. Here, we investigate diversification patterns five lineages amphibians reptiles, across Choco Andes ecoregions northwestern Ecuador....
Over the past decade, research in montane forests of Mira River basin, spanning Ecuador and Colombia, has identified it as crucial for adaptive radiation flora fauna, shaped by its complex geological climatic history. This study focuses on phylogenetic systematic revision a frog clade initially labeled Pristimantis verecundus , revealing significant cryptic diversity. Through detailed analyses type material expanded molecular sampling, we found that original description actually included...
This document contributes 15 new items to the prey list of genus Chironius in Ecuador, based on an examination 89 specimens seven Ecuadorian species. The results agree with previous reports its feeding preference for small ectothermic prey, specifically anurans. Like other studies, data indicate that species inhabiting lower Amazon basin have extensive anuran diet consisting mainly most diverse group anurans region, family Hylidae. In contrast, tropical Andes may be more specialized...
Abstract We present a flora and fauna dataset for the Mira-Mataje binational basins. This is an area shared between southwestern Colombia northwestern Ecuador, where both Chocó Tropical Andes biodiversity hotspots converge. systematized data from 120 sources in Darwin Core Archive (DwC-A) standard geospatial vector format geographic information systems (GIS) (shapefiles). Sources included natural history museums, published literature, citizen science repositories across 13 countries. The...
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...
Galápagos snakes are among the least studied terrestrial vertebrates of Archipelago. Here, we provide a phylogenetic analysis and time calibrated tree for group, based on sampling major populations known to occur in Our study revealed presence two previously unknown species from Santiago Rábida Islands, one Tortuga, Isabela, Fernandina. We also recognize six additional Pseudalsophis Archipelago (Pseudalsophis biserialis San Cristobal, Floreana adjacent islets; hoodensis Española dorsalis...
A new species of Anolis lizard from the Andean slopes southwestern Colombia and northwestern Ecuador, between 1187 2353 m in elevation, is described. The can be distinguished other squamation, cranial osteology, hemipenial morphology, nuclear mitochondrial DNA. sister to Anolisaequatorialis , it suggested that previous records A.aequatorialis correspond described herein.
We provide information about the composition of terrestrial frogs genus Pristimantis in upper basin Upano River, located on Eastern slope Andes Mountain range Morona Santiago province, south-east Ecuador. The compendium 37 species comes from collections conducted an altitudinal gradient between 1170 to 3750 meters. Four are described as new: albujai sp. nov, P. churuwiai sambalan nov and saturtinoi nov. Two reported for first time Santiago, expanding their known distribution. Eight have...
We describe a new species of Pristimantis from the montane forest Río Zuñag Ecological Reserve, upper basin Pastaza River, Ecuador. Pristimantismalliisp. n. is characterized by snout-vent length 11.6-21.3 mm in adult males (n = 12), 22.6-34.3 females 8), and compared morphologically genetically with Pristimantismiktos other relevant Pristimantis.
