Calling rate, corticosterone plasma levels and immunocompetence of Hypsiboas albopunctatus

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2016
During the breeding season, male anuran amphibians produce advertisement calls. Androgens play a permissive role in the activation of calling activity, which is often positively correlated to androgen plasma levels and testes mass. Additionally, calling effort is also correlated to corticosterone plasma levels (hereinafter referred to as CORT), which ...

Skeletal development and adult osteology of Hypsiboas pulchellus (Anura: Hylidae)

Acta Herpetologica, 2012
Osteological and skeletal characters have long been proven to be particularlyinformative in taxonomic and systematic research. Furthermore, ossification sequencesare assumed to be a potential tool to investigate developmental states and developmentalmodes of fossil and extant skeletal specimens.

Post-secretory events alter the peptide content of the skin secretion of Hypsiboas raniceps [PDF]

Biochemical and Biophysical Research Communications, 2008
A novel family of antimicrobial peptides, named raniseptins, has been characterized from the skin secretion of the anuran Hypsiboas raniceps. Nine cDNA molecules have been successfully cloned, sequenced, and their respective polypeptides were characterized by mass spectrometry and Edman degradation.

Antimicrobial Peptides from Skin Secretions of Hypsiboas pulchellus (Anura: Hylidae)

Journal of Natural Products, 2014
The skin of many amphibians produces a large repertoire of antimicrobial peptides that are crucial in the first line of defense against microbial invasion. Despite the immense richness of wild amphibians in Argentina, knowledge about peptides with antimicrobial properties is limited to a few species.

Living together, sometimes feeding in a similar way: the case of the syntopic hylid frogs Hypsiboas raniceps and Scinax acuminatus (Anura: Hylidae) in the Pantanal of Miranda, Mato Grosso do Sul State, Brazil Vivendo juntos e algumas vezes alimentando-se de forma semelhante: o caso das pererecas sintópicas Hypsiboas raniceps e Scinax acuminatus (Anura: Hylidae) no Pantanal do Miranda, Mato Grosso do Sul, Brasil

Brazilian Journal of Biology, 2010
We studied the feeding ecology of two Hylinae anurans (Hypsiboas raniceps and Scinax acuminatus), living sympatrically and syntopically in the Pantanal of Miranda, Mato Grosso do Sul State, Brazil.

B Chromosomes in the Tree FrogHypsiboas albopunctatus(Anura: Hylidae)

Herpetologica, 2012
Supernumerary or B chromosomes are one of the main causes for numerical chromosomal variation in higher eukaryotes. These extragenetic elements have been studied for more than a century, with the goal of trying to understand their origin, and how they survive as a polymorphism in natural populations.
