Morphology and development of additional bony elements in the genus Brachycephalus (Anura: Brachycephalidae)
We describe the extra bony elements, plates, and osteoderms present in species of the genus Brachycephalus. Samples of eight species of Brachycephalus, including seven populations of BrachycephalusExpand
Antimicrobial peptides from the Brazilian frog Phyllomedusa distincta1
Different peptides were purified by chromatographic procedures from the skin-secretory glands of the frog Phyllomedusa distincta. These are the first peptides reported from this frog species. TheirExpand
Further report of the occurrence of tetrodotoxin and new analogues in the Anuran family Brachycephalidae.
Tetrodotoxin (TTX) is one of the most potent toxin already isolated, which occurs in a wide range of marine as well as terrestrial animals such as in newts and anurans. In this work, the occurrenceExpand
The auditory region of Brachycephalus and its bearing on the monophyly of the genus (Anura: Brachycephalidae)
We surveyed the morphology of the auditory region of members of the anuran genus Brachycephalus. The sample included seven of the eleven known species; in addition, Brachycephalus ephippium and B .Expand

A novel heterodimeric antimicrobial peptide from the tree‐frog Phyllomedusa distincta
We present here the purification and the analysis of the structural and functional properties of distinctin, a 5.4 kDa heterodimeric peptide with antimicrobial activity from the tree‐frogExpand
The occurrence of 11-oxotetrodotoxin, a rare tetrodotoxin analogue, in the brachycephalidae frog Brachycephalus ephippium.
11-oxoTTX is an analogue 4-5 times more toxic than TTX itself, been rare even in marine animals. Two ions at m/z 320 and 336 corresponding to TTX and 11-oxoTTX (M+H(+)), respectively, were detectedExpand
A large new species of Rhinella (Anura: Bufonidae) from Cerrado of Brazil
A new toad, Rhinella cerradensis, is described, including its tadpole and the advertisement call. The new species occupies Cerrado habitats in the Brazilian states of Piaui, Bahia, Goias, MinasExpand
The largest lungless tetrapod: report on a second specimen of Atretochoana eiselti (Amphibia: Gymnophiona: Typhlonectidae) from Brazil
The discovery is reported of a second specimen of the radically divergent lungless aquatic caecilian Atretochoana eiselti (Taylor), previously known only from the holotype. Aspects of the morphologyExpand
Internal larval characters in anuran systematic studies: a phylogenetic hypothesis for Leptodactylus (Anura, Leptodactylidae)
There are few systematic studies based on internal buccal and larval cranium morphology of anuran tadpoles. Here we hypothesized phylogenetic relationships of frogs of the Leptodactylus genus with 84Expand
