A new species of milk frog of the genus Trachycephalus tschudi (anura, hylidae)...

Made available in DSpace on 2022-04-29T07:12:53Z (GMT). No. of bitstreams: 0 Previous issue date: 2013-12-01; Smithsonian Institution; We describe a new species of Trachycephalus from the Amazon Rain Forest, which is morphologically similar to T. resinifictrix (Goeldi). This new species is characterized by a medium body size for species in the genus (males snout-vent length [SVL] 57.9-74.3 mm, females SVL 74.4-...

Systematics and historical biogeography of Neotropical foam-nesting frogs of th...

Made available in DSpace on 2021-06-25T10:21:52Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-02-01; A large proportion of the biodiversity of Amazonia, one of the most diverse rainforest areas in the world, is yet to be formally described. One such case is the Neotropical frog genus Adenomera. We here evaluate the species richness and historical biogeography of the Adenomera heyeri clade by integratin...

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...

Land use, habitat integrity, and aquatic insect assemblages in Central Amazonia...

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...

Geographic distribution of aparasphenodon venezolanus (Anura: Hylidae) in the B...

Rediscovery of Osteocephalus vilarsi (Anura: Hylidae): An overlooked but widesp...

Osteocephalus vilarsi (Melin, 1941) is an Amazonian treefrog species known for over 75 years from its holotype only. Due to a lack of published data on its morphological diagnostic characters and their variations, as well as the absence of molecular, acoustic and ecological data supporting its identity, a highly dynamic taxonomic history has led this species to be confused and even synonymised with other Osteoc...

Cinerascetins, new peptides from Hypsiboas cinerascens : MALDI LIFT-TOF-MS/MS d...

The continuous search for antimicrobial candidates pushes the pursuit of compounds in the most diverse organisms. Amphibians are known as a prolific source of antibacterial peptides. Based on the rich biodiversity of the Amazon region the unexplored green-tree frog (Hypsiboas cinerascens) was studied for its skin secretion peptide content. Chromatographic separations and established tandem mass spectrometry (MS...
