River impoundment and the alteration of the hydrological regime of aquatic ecosystems are suggested to be one of the major disturbances to aquatic ecosystem functions and biodiversity. Reservoirs are "novel"ecosystemsthat combinefeaturesoflakes(i.e.vertical gradients)and rivers(i.e.horizontal gradients). We know very little about the dominantecological processesin reservoirs,how they can be comparedto natural lakes andrivers,and howtrophic interactionsandfood webs evolvein reservoirs.
