Última Variação geográfica de caracteres quantitativos em Ogcocephalus vespertilio (Linnaeus) (Teleostei, Lophiiformes, Ogcocephalidae) Zoologia Cavalcanti,Mauro José; Lopes,Paulo Roberto Duarte. Patterns of geographic variation in 10 morphometric characters were analyzed in a sample of 91 specimens of the batfish, Ogcocephalus vespertilio (L.), from the NE and SE Brazilian coast, using multivariate statistics and randomization tests. The specimens were ordinated by principal components analysis in two groups corresponding to the regions north and south of the 23ºC isotherm, and size variation was found to account for 70.3%, whereas shape differences accounted for 23.6% of the total variation in morphometric characters. The two groups were different at the 1% significance level by multivariate analysis of variance based on the Wilk's criterion, tested by a randomization procedure. Width of illicial cavity and distance from anus to anal fin were the...

Ano: 1998 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0101-81751998000100010 Morfometria comparada de Ctenosciaena gracilicirrhus, Paralonchurus brasiliensis e Micropogonias furnieri (Teleostei: Sciaenidae) pela análise multivariada de redes de treliças Zoologia Cavalcanti,Mauro José; Lopes,Paulo Roberto Duarte. Comparative morphometrics of Ctenosciaena gracilicirrhus, Paralonchurus brasiliensis and Micropogonias furnieri (Teleostei: Sciaenidae) by multivariate analysis of truss networks. Morphological differentiation among three species of sciaenid fishes, Ctenosciaena gracilicirrhus, Paralonchurus brasilliensis and Micropogonias furnieri, was analyzed by multivariate statistical techniques, using measuraments obtained from truss networks based on anatomical landmarks. Principal components analysis of interlandmark distances defined by the truss system showed that the individuais of Ctenosciaena gracilicirrhus are different from those of the other two species in relation to shape, being more similar to the individuals of Micropogonias furnieri in relation to size.
