We describe a new species of frog of the genus Chiasmocleis from the montane forests of southeastern Ecuador, at the western slopes of Cordillera del Cóndor, between 1,224‑1,630 m of elevation. Based on new sequences of ...

We studied populations of frogs of the genus Atelopus from the Pasto Massif of the Andes in southern Colombia and north- ern Ecuador, and from the Huancabamba depression in southern Ecuador and northern Perú and conclude ...

La Escuela Superior Politécnica del Litoral, impulsando la sociedad del conocimiento, mediante la Facultad de Ciencias de la Vida encargada de organizar las cuadragésimas XL Jornadas Nacionales de Biología, evento promocionado ...

Pluralistic approaches to taxonomy facilitate a more complete appraisal of biodiversity, especially the diversification of cryptic species. Although species delimitation has traditionally been based primarily on morphological ...

Premise: Third-generation sequencing methods generate significantly longer reads than those produced using alternative sequencing methods. This provides increased possibilities for the study of biodiversity, phylogeography, ...

Many vertebrates have distinctive blue-green bones and other tissues due to unusually high biliverdin concentrations—a phenomenon called chlorosis. Despite its prevalence, the biochemical basis, biology, and evolution of ...

We describe through integrative taxonomy a new Amazonian species of leaf-litter toad of the Rhinella margaritifera species group. The new species inhabits open lowland forest in southwest Amazonia in Brazil, Peru, and ...

We describe a new species of the hylid frog genus Dendropsophus from Amazonian Ecuador. The new species, Dendrop-sophus shiwiarum sp. nov., appears to be part of the D. microcephalus species group. Dendropsophus shiwiarum ...

We describe a small frog of the genus Pristimantis inhabiting bromeliads (snout-vent length 20.3-23.3 mm in females, 16.1-17.4 mm in males), from a remote sandstone plateau of the Cordillera del Condor, in southeastern ...
