Taxonomic review of Scinax fuscomarginatus (Lutz, 1925) and related species (Anura; Hylidae)
(Zoological Journal Of The Linnean Society, 2014-08-01) [Artigo]
Scinax fuscomarginatus, Scinax parkeri, Scinax trilineatus, Scinax lutzorum, and Scinax pusillus are morphologically similar species with controversial taxonomy associated with open formations of South America east of the ...
Partitioning the net effect of host diversity on an emerging amphibian pathogen
(Proceedings Of The Royal Society B-biological Sciences, 2014-11-22) [Artigo]
The 'dilution effect' (DE) hypothesis predicts that diverse host communities will show reduced disease. The underlying causes of pathogen dilution are complex, because they involve non-additive (driven by host interactions ...
Integrative taxonomy supports the existence of two distinct species within Hypsiboas crepitans (Anura: Hylidae)
(Salamandra, 2017-02-15) [Artigo]
The Neotropical treefrog Hypsiboas crepitans (WIED, 1824) has an intriguing disjunct geographic distribution encompassing two large patches: the Atlantic Forest in southeastern South America and from the Guiana Shield to ...
What happened in the South American Gran Chaco? Diversification of the endemic frog genus Lepidobatrachus Budgett, 1899 (Anura: Ceratophryidae)
(Molecular Phylogenetics And Evolution, 2018-06-01) [Artigo]
The Chaco is one the most neglected and least studied regions of the world. This highly-seasonal semiarid biome is an extensive continuous plain without any geographic barrier, and in spite of its high species diversity, ...
Physiological responses of Brazilian amphibians to an enzootic infection of the chytrid fungus Batrachochytrium dendrobatidis
(Diseases Of Aquatic Organisms, 2016-01-13) [Artigo]
Pathophysiological effects of clinical chytridiomycosis in amphibians include disorders of cutaneous osmoregulation and disruption of the ability to rehydrate, which can lead to decreased host fitness or mortality. Less ...
The mitochondrial genomes of three species of poison frogs (Anura:Dendrobates)
(Mitochondrial Dna Part B-resources, 2017-01-01) [Artigo]
We reconstructed nearly complete mitogenomes for three species of poison frogs, Dendrobates auratus, D. leucomelas, and D. tinctorius, from RNAseq data. We recovered the 13 protein-coding genes, 22 tRNA genes (except ...
Perspectives on invasive amphibians in Brazil
(Plos One, 2017-09-22) [Artigo]
Introduced species have the potential to become invasive and jeopardize entire ecosystems. The success of species establishing viable populations outside their original extent depends primarily on favorable climatic ...
Molecular phylogeny of Neotropical rock frogs reveals a long history of vicariant diversification in the Atlantic forest
(Molecular Phylogenetics And Evolution, 2018-05-01) [Artigo]
The Brazilian Atlantic coastal forest is one of the most heterogeneous morphoclimatic domains on earth and is thus an excellent region in which to examine the role that habitat heterogeneity plays in shaping diversification ...
Freshwater vertebrate metabarcoding on Illumina platforms using double-indexed primers of the mitochondrial 16S rRNA gene
(Conservation Genetics Resources, 2016-09-01) [Artigo]
Metabarcoding is a promising tool for biodiversity inventories and other applications in conservation genetics. We developed a new pair of primers for efficient and affordable high-throughput analysis of a 250 base pair ...
A new species of ischnocnema parva species series (Anura, Brachycephalidae) from northern state of Rio de Janeiro, Brazil
(Herpetologica, 2013-06-01) [Artigo]
Here we describe a new species of the Ischnocnema parva species series from the Parque Estadual do Desengano, in the northern part of the State of Rio de Janeiro, Brazil. We use morphology and mtDNA sequences to allocate ...
