AMADEU SANTANA, Ana Rute; WERTH, Martin  and  BENEDITO-CECILIO, Evanilde. USE OF FOOD RESOURCES BY DETRITIVOROUS FISH IN FLOODPLAINS: A SYNTHESIS. Acta biol.Colomb. [online]. 2015, vol.20, n.1, pp.5-14. ISSN 0120-548X.

The present review investigated the sources of energy for detritivorous fish species in floodplains. Recent studies have shown that environmental changes that alter the terrestrial vegetation affect essentially the resource base in these areas, such as the detritus. In aquatic environments, especially floodplains, a major part of metabolic processes is supported by terrestrial detritus, which accounts for maintaining the detritivorous food chain. Thus, one way to evaluate environments changes is through isotopic studies of organic matter, which allows acquiring information about the quantity and quality of organic matter. This approach is required for understanding the interactions between the organic matter dynamics and its ecological effects, allowing the monitoring of these resources. However, researches on the energy flow in food chains should also employ an approach that quantifies the magnitude of these food subsidies, as also the access routes of aquatic consumers, in watersheds of different sizes and in diverse land uses.

Keywords : environmental changes; detritus; microbial biomass; stable isotopes.
