1. Plasticity in the shape and growth pattern of asteriscus otolith of black prochilodus Prochilodus nigricans (Teleostei: Characiformes: Prochilodontidae) freshwater Neotropical migratory fish
RESUMO Medidas e funções wavelets dos otólitos asteriscus de curimatã, Prochilodus nigricans foram analisados para identificar a variação da forma e do incremento de crescimento dos indivíduos dos rios Solimões, Japurá e Negro da bacia Amazônica, Brasil. As análises morfométricas e morfológicas não revelaram evidências de segregação populaci

2. Análise multivariada da forma do otólito sagita para discriminação de estoques de dourado, Coryphaena hippurus (Pisces : Coryphaenidae), no Nordeste do Brasil / Multivariate analysis of otolith shape for stock discrimiantion of dolphinfish,Coryphaena hippurus (Pisces :Coryphaenidae), in the Northeastern Brazilian coast
The otolith shape of dolphinfish, C. Hippurus, was studied to verify the hypotheses of two stocks in the northeastern Brazilian coast. Eighty two sagittal otoliths were collected from specimens caught by the artisanal fleet in two regions of northestern Brazil (Maranhão MA and Rio Grande do Norte RN coasts), in December of 2003 and April to May of 2004, res

3. Physiological evidence for binaural directional computations in the brainstem of the oyster toadfish, Opsanus tau (L.)
Comparisons of left and right auditory input are required for sound source localization in most terrestrial vertebrates. Previous physiological and neuroanatomical studies have indicated that binaural convergence is present in the ascending auditory system of the toadfish. In this study, we introduce a new technique, otolith tipping, to reversibly alter
