| sexual dichromatism in the neotropical genus mannophryne (anura: aromobatidae). | recent reviews on sexual dichromatism in frogs included mannophryne trinitatis as the only example they could find of dynamic dichromatism (males turn black when calling) within the family aromobatidae and found no example of ontogenetic dichromatism in this group. we demonstrate ontogenetic dichromatism in m. trinitatis by rearing post-metamorphic froglets to near maturity: the throats of all individuals started as grey coloured; at around seven weeks, the throat became pale yellow in some, and ... | 2020 | 32639962 |
| external gill motility and striated muscle presence in the embryos of anuran amphibians. | anuran external gills were assessed for motility and striated muscle content in 16 species from seven families. motility of three kinds was observed. pulsatory movements related to heart beat rhythm were common. in embryos developing to a late stage before hatching, movements of the whole embryo were frequent, with gills rearranging as a consequence. the only clearly active movement, presumably muscle driven, was 'gill flicking', a posterior movement of the entire gill into the body either on on ... | 2013 | 23116755 |
