Uncovering the diversity in the amazophrynella minuta complex: Integrative taxo...

A new species of the genus Amazophrynella (Anura, Bufonidae) is described from the departments of Madre de Dios, Cusco and Junin in Peru. An integrative taxonomy approach is used. A morphological diagnosis, morphometrics comparisons, description of the advertisement call, and the phylogenetic relationships of the new species are provided. Amazophrynella javierbustamantei sp. n. differs from other species of Ama...

A Pan-Amazonian species delimitation: High species diversity within the genus A...

Amphibians are probably the most vulnerable group to climate change and climatechange associate diseases. This ongoing biodiversity crisis makes it thus imperative to improve the taxonomy of anurans in biodiverse but understudied areas such as Amazonia. In this study, we applied robust integrative taxonomic methods combining genetic (mitochondrial 16S, 12S and COI genes), morphological and environmental data to...

First record of Amblyomma rotundatum Koch, 1844 (Acari: Ixodidae) parasitizing ...

This is the first record of Amblyomma rotundatum parasitizing Paleosuchus palpebrosus. This record was made during a herpetofaunal study carried out in high elevation habitats that are under protection in the mountain range "Serra do Amolar", located in the western border of Brazilian Pantanal, in the state of Mato Grosso do Sul.

Hêliconias como alternativa econômica para comunidades amazônicas

Reservas extrativistas (RESEX) são espaços territoriais destinados à exploração sustentável e conservação dos recursos naturais renováveis, por populações extrativistas. Além disso, tem como finalidade implantar alternativas de renda que contribuam para a melhoria das condições de vida das famílias locais. Dentre as variadas possibilidades de renda pelas comunidades que compõem as RESEX, destacamos neste trabal...

Morphology and geographical distribution of the poorly known snake Umbrivaga py...

The article describes morphology and geographical distribution of the poorly known snake Umbrivaga pygmaea in Brazil. The South American snake genus Umbrivaga Roze, 1964, is found in Colombia, Peru, Ecuador, French Guiana, Venezuela, and Brazil. The hemipenes are slightly bilobed, bearing several spines and apical discs in the distal region of the lobes, which are neither capitate nor calyculate. Inverted, the ...

New record and range extension of the horned toad, rhinella ceratophrys (Boulen...

The Horned Toad, Rhinella ceratophrys, is widely distributed in the northwestern part of the Amazon region. It is known from Venezuela by only a single juvenile from the base of Cerro Marahuaca, Amazonas state. Herein we report four additional specimens from Venezuela: three juveniles also from Cerro Marahuaca, and a subadult female from the southern slopes of Cerro La Neblina, at the southern border of Amazona...

Integrative overview of the herpetofauna from serra da mocidade, a granitic mou...

The Brazilian mountain ranges from the Guiana Shield highlands are largely unexplored, with an understudied herpetofauna. Here the amphibian and reptile species diversity of the remote Serra da Mocidade mountain range, located in extreme northern Brazil, is reported upon, and biogeographical affinities and taxonomic highlights are discussed. A 22-days expedition to this mountain range was undertaken during whic...
