Última Ecomorphology and use of food resources: inter- and intraspecific relationships of fish fauna associated with macrophyte stands Neotropical Ichthyology Prado,Aline V. R.; Goulart,Erivelto; Pagotto,João P. A.. ABSTRACT Based on the form-function interaction and its consequence to niche exploitation by fish species, the study aimed to identify ecomorphological patterns and to investigate the possibility of explaining the trophic niche breadth using the pattern of intraspecific ecomorphological diversity. We tested the following hypotheses: i) the morphology explains variations in diet among fish species; ii) the intraspecific ecomorphological diversity is related to the breadth of the trophic niche explored by the species, so that species that feed on a wider range of resources have greater variation in body shape compared to those specialized in resource consumption. Fish were collected in stands of the aquatic macrophytes Eichhornia azurea and Eichhornia...

Considering th e morphology, diet and spatial distribution of Satanoperca pappaterraand Crenicichla britskii (Perciformes: Cichlidae) in the Upper Paraná River floodplain (Brazil), the following questions were investigated: (1) Could the body shape predict the use of trophic resources and habitat by C. britskiiand S. pappaterra? (2) Could the relationship between morphology and use of trophic resources and habitat be also extended to the intraspecific scale? (3) What are the most important morphological traits used to predict the variation on diet and habitat occupation within and between species? We hypothesized that intra and interspecific differences in morphological patterns imply in different forms of resource exploitation and that the...

Bras. Zool. Serafim-Júnior,Moacyr; Perbiche-Neves,Gilmar; Lansac-Tôha,Fabio A.. ABSTRACT Zooplankton exhibit several trends of variation in space and time, and these trends can be more evident in natural environments without anthropic perturbations. Examples of anthropic factors are climate change, eutrophication and construction of reservoirs. This study evaluated the influence of three factors - seasonality, type of environment and the presence of aquatic macrophytes - on various ecological attributes of rotifers in a river-lake system located in the Paraná River floodplain. Monthly samplings were conducted during 1993 and 1994. The mean species richness per sample was 60 species. The seasonality and the type of environment influenced the ecological attributes of rotifer assemblages, while the presence or absence of aquatic...

One hundred and forty-eight specimens of Prochilodus lineatus (Valenciennes, 1836) were collected on the Upper Paraná River floodplain, Brazil. Kritskyia boegeri presented significant differences in the abundance according to the host stage of gonadal maturity. Ergasilus sp. presented negative correlation between the GSR of the females and parasite abundance. K. boegeri presented negative correlation between the GSR of the males and abundance. Tereancistrum curimba and Saccocoelioides magnorchis occurred in higher abundance in the open lagoons. Rhinonastes pseudocapsaloideum and S. nanii presented higher abundance in the channels and Tylodelphis sp. presented higher abundance in the closed lagoons and in the rivers. K. boegeri and Amplexibranchius sp.... Tipo: Info:eu-repo/semantics/article Palavras-chave: Prochilodus lineatus; Parasite; Upper Paraná River floodplain; Brazil.
