1 Ecological Implications of Erratic Floods in Large River Floodplains of the Andean Amazon Region Jorge E. Celi & Stephen K. Hamilton Department of Zoology & Kellogg Biological Station Michigan State University
2 The Flood Pulse Concept (Junk et al. 1989) Floodplains are transitional between aquatic and terrestrial zones. Large unmodified watersheds produce flood pulses of long duration and extensive seasonal floodplain inundation. Small or modified systems produce frequent flood pulses of shorter duration. Predictable pulses allow organisms to adapt to and benefit from inundation. Unpredictable pulses act as a disturbance and impede adaptation.
3 The Natural Flow Regime concept can be extended to Flood Regimes on floodplains Poff et al The Natural Flow Regime. Naiman et al. 28. Flow variability and the biophysical vitality of river systems.
4 The Napo River Drains 1 5 km 2 of a highly diverse and largely undisturbed region of the western Amazon in Ecuador and Peru. Fringed with extensive floodplains along 8 km of lowland reaches. Exceptional levels of biodiversity may be related to flood regimes. Intermediate disturbance hypothesis

Contrasts with more predictable, mono-modal regimes of the Amazon, Orinoco, Parana rivers. Stage fluctuations range from 4 m in upper reaches to 9 m in lower reaches, vs. 16 m in the central Amazon upstream Napo - Ecuador Source: INAMHI-SENAMHI, Hybam Project Source: ANA, Brazil.
