1. Otolith morphometry provides length and weight predictions and insights about capture sites of Prochilodus lineatus (Characiformes: Prochilodontidae)
RESUMO Neste trabalho o curimba Prochilodus lineatus foi utilizado para responder as seguintes questões: Como o comprimento e o peso dos otólitos são correlacionados com o comprimento e o peso do peixe? Até que ponto as medidas dos otólitos são confiáveis para predizer a idade do P. lineatus? Finalmente, nós propomos equações preditivas do comprime

2. Migration and brackish environment use of Prochilodus lineatus (Characiformes: Prochilodontidae) inferred by Sr:Ca ratio transects of otolith
ABSTRACT The streaked prochilod, Prochilodus lineatus, represents the most important fishery in the La Plata Basin (South America). Our objective was to analyze brackish environment use by the streaked prochilod captured from Paraná and Uruguay rivers. To accomplish this, lapillus otolith sections were analyzed for Sr:Ca with laser ablation-inductively coup

3. Morphological variations of the three otoliths of some species of the family Loricariidae (Ostariophysi: Siluriformes)
ABSTRACT Otoliths are three pairs of calcareous structures found in the inner ear of bony fish. In many cases they display a species-specific morphology. The present study describes morphological variations of otoliths, namely lapillus, asteriscus and sagitta, of eleven species belonging to four loricariid subfamilies. Otolith structures that characterize th

4. Idade e crescimento de Hemiramphus brasiliensis (Linnaeus, 1758) no litoral de Pernambuco
The Ballyhoo, Hemiramphus brasiliensis, has a key role in the ecosystem and in the fisheries. Studies on the biology and dynamics of populations are of fundamental importance for the management of fisheries resources and to better understand its role in the ecosystems. This work aims to study the age and growth of H. brasiliensis at Pernambuco coast, using t

5. Morphological and biochemical analyses of otoliths of the ice-fish Chionodraco hamatus confirm a common origin with red-blooded species
The morphology and composition of the three otoliths of the Antarctic ice-fish Chionodraco hamatus were studied by scanning electron microscopy and X-ray diffraction. The composition of the sagitta, lapillus and asteriscus protein matrices was also analysed by sodium dodecyl sulphate-polyacrylamide gel electrophoresis, western blots and confocal laser scanni

6. Calcification in marine molluscs: how costly is it?
Although crucial to our understanding of skeletal evolution in marine invertebrates, the cost of calcification has remained elusive for a simple reason: CaCO3 is an inorganic material. Its cost thus derives solely from the metabolic expenses of accumulating, transporting, and precipitating CaCO3 and cannot normally be separated from other metabolic costs. Tr
