“…The four Diplodus patterns are identical to those previously noted (Basaglia & Marchetti, 1990). In order to examine further these differences, muscle extracts were subjected to isoelectric focusing using narrow pH range gels (pH 4.0-6.5), thus achieving greater resolution of the anodal and middle portions of the pH gradient.…”

“…Electrophoresis is the main method for analysis of the biochemical systematics in various taxa. In most cases, where species have been examined for a sufficient number of proteins by means of high-resolution starch gel electrophoresis or polyacrylamide gel isoelectric focusing, species-specific protein patterns have been found (O'Rourke, 1974;Ferguson, 1974;Basaglia & Marchetti, 1990). In general, the more closely related the species are, the greater is the similarity in their patterns.…”

Soluble proteins of white skeletal muscle tissue of 15 species of Sparidae were analysed. Speciesspecific electrophoretic and isoelectric focusing patterns were found. Some bands exhibited the same mobility at genus level or at subfamily level, others differed significantly.Considerable similarity was observed in the species of the genera Spurus, Pugellus and Diplodus. Significant differences in the protein bands were noted between the contained subfamilies Denticinae, Sparinae and Boopsinae, confirming the existence of three separate phyletic lines within the family Sparidae.This study has shown that in these species there is a similarity between classifications based on morphological data and those derived from biochemical studies.Variation within species can be corrected for by carrying out multiple inter-specific comparisons and determining the variance of the similarity coefficients. Closely related species have similar patterns and, thus, higher similarity coefficients.The discrepancy in similarity matrices based on morphology and white skeletal muscle tissue proteins of sea bream species shows that electrophoretic methods provide additional information relevant to the systematics of fishes.Further work on comparison on soluble red muscle proteins of these species is proposed.

“…The first allozyme studies on the genetic structure of D. sargus were based on few loci and individuals; little information concerning structure and genetic variability was available (Vazzana et al ., 1990). Since then, several studies on enzymatic variability of D. sargus have been published (Basaglia & Marcheti, 1990; Santulli et al ., 1991; Reina et al ., 1994; Lenfant & Planes, 1996a, b; Cervelli, 1998, 1999). Some have shown significant differentiation between populations.…”

Allozyme analysis of tissue samples of 1249 white sea bream Diplodus sargus from five localities of the south‐west Mediterranean revealed a high degree of genetic polymorphism. The observed heterozygosity ranged from 0.4182 (Cape of Palos) to 0.3138 (Tabarca). Several populations were characterized by unique alleles. Examination of the spatial structure was performed using Nei's distances and F‐statistics, and indicated genetic differences between groups. One group, which clustered Tabarca and Guardamar, could be explained by the small geographical distance between them. Mazarrón and Cape of Palos samples showed genetic divergence from other samples (Guardamar, Tabarca and Águilas) and this difference may be as a result of local current systems and larval dispersal. © 2004 The Linnean Society of London, Biological Journal of the Linnean Society, 2004, 82, 249–261.

Soluble red muscle proteins from the lateral line of 15 Sparidae species were analysed by isoelectric focusing. Species-specific patterns were found. The species-specific protein fractions could be correlated with different metabolic activities and with different growth indexes. More protein fractions were identified for Puge//us ucurne (Risso) and Dijdodus onnuluris (L.) than for the other 13 species. This would appear to be related to growth index. The existence of red muscle with a greater number of protein bands than white muscle was confirmed in almost all species. The similarity coefficients have shown that closely related species have similar patterns and, thus, higher similarity coefficients. The derived dendrogram agrees with previous classifications based on morphological information.
