Ecology and status of piscivores in Guri, and oligotrophic
The predominance of inverted biomass pyramids in the plankton of oligotrophic
areas would suggest, according to this alternative hypothesis, a greater impact of allochthonous organic subsidies on these communities.
Similar distinctions between oligotrophic
blackwater (sediment-poor) and eutrophic alluvial or redwater (sediment-rich) systems occur in many other regions of the world and, in particular, in the southeastern United States (Sharitz & Mitsch, 1993; Walbridge & Lockaby, 1994; Wharton et al.
