Efeitos da variação térmica no sistema pigmentar extracutâneo do anuro Eupemphix nattereri (Anura: Leiuperidae)
(Universidade Estadual Paulista (Unesp), 2010-06-02)
Os vertebrados ectotérmicos apresentam um desenvolvido sistema de células com pigmentos melânicos em seu citoplasma, localizadas em diversos órgãos e estruturas formando um sistema pigmentar extracutâneo. Esses tipos ...

Biomarkers at different levels of organisation after atrazine formulation (SIPTRAN 500SC®) exposure in Rhinella schineideri (Anura: Bufonidae) Neotropical tadpoles
(2019-01-01)
Brazil is an important consumer of herbicides. In sugarcane cultivation—the country's most extensive agricultural crop—atrazine-based formulations are the principal form of weed control. Several studies have investigated ...
A comparative study of the extracutaneous pigmentary system in three anuran amphibian species evaluated during the breeding season.
(2009-04-01)
The present investigation examined the extracutaneous pigmentation pattern of three species of anuran amphibians, Dendropsophus nanus, Physalaemus cuvieri, and Rhinella schneideri, during the course of their breeding ...

Pigmentation in Anuran Testes: Anatomical Pattern and Variation
(Wiley-Blackwell, 2009-02-01)
In amphibians, pigmented cells are present in several organs, composing an extracutaneous pigmentary system. Seventeen species from two families were studied to develop a protocol for pigmentary classification. The amount ...
