Predator-prey: predation strategies of Leptodactylus macrosternum and defensive...
Costa, Claylton Abreu; Uchôa, Lucas Rafael; Araújo, Sâmia Caroline Melo; Oliveira, Mariane Silva; Andrade, Etielle BarrosoCongeneric predation between two Leptodactylus species was recorded and information was collected on the predation strategy of L. macrosternum and the defensive behavior and distress call of L. fuscus. The entire predation event lasted about 90 min and ended when predator tore integument of the prey's ventral region, facilitating swallowing. The distress call description was based on a record of 40 s containing...
Characterization and Biological Activities of Ocellatin Peptides from the Skin ...
Marani, Mariela Mirta; Dourado, Flávio Santos; Quelemes, Patrick Veras; Araujo, Alyne Rodrigues de; Perfeito, Márcia Luana Gomes; Barbosa, Eder AlvesEight new peptides were isolated from the skin secretion of the frog Leptodactylus pustulatus and their amino acid sequences determined by de novo sequencing and by cDNA cloning. Structural similarities between them and other antimicrobial peptides from the skin secretion of Leptodactylus genus frogs were found. Ocellatins-PT1 to -PT5 (25 amino acid residues) are amidated at the C-terminus, while ocellatins-PT6...
