Size-Dependent Selective Mechanisms on Males and Females and the Evolution of Sexual Size Dimorphism in Frogs
(American Naturalist, 2014-12-01) [Artigo]
Sexual size dimorphism (SSD) varies in animals from male biased to female biased. The evolution of SSD is potentially influenced by a number of factors, such as territoriality, fecundity, and temporal breeding patterns ...
Microsatellite markers for Bokermannohyla species (Anura, Hylidae) from the Brazilian Cerrado and Atlantic Forest domains
(Amphibia-reptilia, 2014-01-01) [Artigo]
We characterized 22 polymorphic microsatellite markers for the Brazilian treefrog Bokermannohyla ibitiguara and tested their cross-amplification in B. alvarengai, B. circumdata and B. hylax. Our focal species occurs in ...
Complex Call with Different Messages in Bokermannohyla ibitiguara (Anura, Hylidae), a Gladiator Frog of the Brazilian Cerrado
(Journal Of Herpetology, 2014-09-01) [Artigo]
The Gladiator Frog, Bokermannohyla ibitiguara, is a hylid endemic to the Brazilian Cerrado with a complex call composed of long and short notes. We describe the influence of male size and temperature on call properties and ...
Role of central nitric oxide in behavioral thermoregulation of toads during hypoxia
(Physiology & Behavior, 2008-09-03) [Artigo]
Nitric oxide (NO) is thought to play a key role in the development of hypoxia-induced anapyrexia in mammals, acting on the preoptic region of the anterior hypothalamus to activate autonomic heat loss responses. Regarding ...
