1. Influência da massa corporal, da filogenia e do habitat sobre a estrutura da vocalização de aves brasileiras
A comunicação é um fator muito importante para a manutanção de diversos processos ecológicos vitais entre os animais. Entre as aves, a comunicação acústica tem papel primordial e é indispensável para a reprodução, repulsão de predadores e dinâmica social. A massa corporal impõe restrições fisiológicas ao aparelho vocal e, consequentemente,

2. Conservatism and diversification of plant functional traits: Evolutionary rates versus phylogenetic signal
The concepts of niche conservatism and adaptive radiation have played central roles in the study of evolution and ecological diversification. With respect to phenotypic evolution, the two processes may be seen as opposite ends of a spectrum; however, there is no straightforward method for the comparative analysis of trait evolution that will identify these c

3. The evolution of coloration and toxicity in the poison frog family (Dendrobatidae)
The poison frogs (family Dendrobatidae) are terrestrial anuran amphibians displaying a wide range of coloration and toxicity. These frogs generally have been considered to be aposematic, but relatively little research has been carried out to test the predictions of this hypothesis. Here we use a comparative approach to test one prediction of the hypothe
