| In order to define the structure of trophic network of Ichkeul Lake in Tunisia, diet of main teleost fish species was determined during two seasons, wet and dry. A total of 491 stomachs from 16 teleost species was analyzed. The analysis revealed spatial variability (East under marine influence and West with more continental effect) and temporal one (wet and dry seasons). Based on stomach contents, nine trophic groups were revealed, including eight monospecific groups. The main prey are mudflat snails (Hydrobia ventrosa, H. acuta), bivalves (Abra alba, Cerastoderma glaucum), amphipods and isopods, as well as seagrass (Potamogeton pectinatus, Ruppia cirrhosa) and water brackish algae (Ulva spp. and Chaetomorpha spp., Cladophora sp., Polysiphonia sp.). |

| This paper is a part of the studies on the Coleoptera fauna from Vila Velha, Ponta Grossa, Parana gathered through malaise and pitfall traps in sites with different floristic conditions. The present study deal with the data of pitfall trap captures, installed close to the malaise traps. The data were obtained weekly (52 samples), from September 1999 to August 2000. This survey was carried out on five areas, three of them with different plant succession stages (initial, intermediate, and advanced). The other two sites were: in Araucaria angustifolia plantation area, with the understory invaded by native forest vegetation and in the edge area. In the last one, two pitfall traps were installed, one inside the forest and other in the field vegetation. The... |

| We described the spatial distribution of fish trophic groups in the Água Boa Stream, MS, Brazil. Specimens were caught using electrofishing in the upper, intermediate and lower stretches of the stream, between March and November 2008. We analyzed 415 stomach contents of 24 species. Detritus/sediment and aquatic invertebrates were the main exploited resources. Ordination analysis categorized the species in six trophic groups. Aquatic invertivores showed the highest richness (10 species), followed by detritivores (08 species), omnivores (03 species), terrestrial invertivores (03 species), algivores (02 species) and herbivore (01 species). Three trophic groups occurred in the upper stretch, six in the intermediate and five in the lower. Detritivores,... |
