Benthic macroinvertebrate community structure in a stream of the north-west region of Paraná State, Brazil
Provedor de dados: Biota Neotropica
Autores: Bagatini,Yara Moretto; Delariva,Rosilene Luciana; Higuti,Janet.
This study aimed to survey the benthic macroinvertebrate fauna of a first order stream located in an agricultural area, and to assess the environmental factors involved in the spatial distribution of this community. Invertebrates were gathered in November 2007 at three sampling sites distributed along the Itiz Stream, located in Marialva municipality, Paraná State. At each site, we measured the physical and chemical variables of the water, and then took four samples, using Surber sampler. In order to evaluate the differences in density, richness, diversity and evenness, we employed an ANOVA and a DCA to summarize biotic data. The invertebrates were categorized into functional groups and the BMWP score was applied to calculate the biological integrity of...

Caloric variability of Corbicula fluminea (Mollusca, Bivalvia) in Rosana Reservoir, Brazil
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: 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.
