Outline - Tropical Rivers
PP SLIDE - river traits:
1. flow is unidirectional; downstream reaches are influenced by upstream reaches
2. running waters are linear and occupy small portion of the watershed.
3. channel substrata and morphology are dynamic; they are unstable and undergo constant change
4. much of organic matter is allochthonous, especially in low-order streams
5. spatial and temporal heterogeneity are high
6. high variablity of biotic and abiotic characteristics in streams and rivers
7. biota are adapated to flowing water conditions.
