13. Relações tróficas e limnológicas no reservatório de Itaipu: uma análise do impacto da biomassa pesqueira nas comunidades planctônicas / Trophic and limnological interactions in the Itaipu reservoir: an analysis of the impact of the fishing biomass in the planktonic communities
Many experimental studies contributed for the development of the theory of the lacustrine food web, disclosing the important paper of the fish, for decades ignored by the limnology. These studies, in its majority, had been developed in Europe and North America and the generality of the hypotheses supporting the theory was not tested yet in subtropical and tr

14. INFLUÊNCIA DO PULSO DE INUNDAÇÃO NA COMPOSIÇÃO ISOTÓPICA (d13C E d15N) DAS FONTES PRIMÁRIAS DE ENERGIA NA PLANÍCIE DE INUNDAÇÃO DO RIO PARAGUAI (PANTANAL MS) / SEASONAL PATTERN DETERMINING PRIMARY ENERGY SOURCES d13C AND d15N IN THE PARAGUAY RIVER FLOODPLAIN TROPHIC WEB, PANTANAL WETLAND - BRAZIL
The food web of the Pantanal wetland in Brazil was investigated during a complete hydrologic cycle (1998-99) using a multiple stable isotope approach (d13C and d15N) with the goal of identifying the primary carbon sources, which drive the system energy flux. The sampling was done in a representative marginal lake (Baía do Castelo) of Paraguay River floodpla
