Última Reproductive Strategies of Plagioscion squamosissimus Heckel, 1840 (Osteichthyes Sciaenidae) in the Itaipu Reservoir, Brazil BABT Carnelós,Regina Cintia; Benedito-Cecilio,Evanilde. Plagioscion squamosissimus is a dominant species in the Itaipu reservoir and has a significant role in the regional economy. The aim of the present research was the investigation of the curvina's reproductive strategies during the first years of the Itaipu reservoir (November 1983 to October 1989). Collections were undertaken from eleven sampling sites in the reservoir area, left bank tributaries, Paraná River and its tributaries. Species begin the reproduction in the area of influence of the Itaipu reservoir only in 1986. Size of early maturation, local and period of spawning showed gradual variations, with a broadening trend of this activity in the area, and thus guaranteeing success of the species. Mean size of early sexual maturation for the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Reproduction; Itaipu reservoir; Plagioscion squamosissimus; Impact.

The aim of this work was to determine the caloric density of leaves, stems and roots of aquatic macrophytes in different environments of the Baía subsystem (Baía river and Fechada and Guaraná lagoons) on the Upper Paraná river floodplain, in addition to identify the variability between ecological groups. Samplings of Eichhornia crassipes, Salvinia spp, Pistia stratiotes, Eichhornia azurea, Polygonum sp, Cyperaceae and Poaceae were carried out in February 2003. Spatial differences in the caloric densities were not observed for these plants. Caloric density values varied from 1906.9 cal/g dry weight (root) to 4675.0 cal/g dry weight (leaf). However, significant differences between the caloric content averages of the vegetative structures were observed only...

Ano: 2006 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-89132006000600018 Caloric variability of Corbicula fluminea (Mollusca, Bivalvia) in Rosana Reservoir, Brazil BABT Bagatini,Yara Moretto; Benedito-Cecilio,Evanilde; Higuti,Janet. The purpose of the present study was to investigate temporal and longitudinal variation of caloric density of Corbicula fluminea in Rosana Reservoir. Significant differences concerning the caloric density of C. fluminea were observed throughout the year at the three reservoir sites. The caloric density variation during the year was probably related to reproductive activity, which demanded higher allocation of energy in certain period. The food source used by this species might be an important factor in the caloric value temporal and spatial variation of C. fluminea in Rosana Reservoir.
