Influence of Limnological Processes and Water Level Variation on the Biodiversity of Brazilian Amazon Lakes: An Ecological Approach

This research makes a brief review of the limnology lakes in wetlands Western Amazon, associating physical-chemical and morphological aspects to biodiversity black-waters whitewaters lakes. Lakes these areas can show different patterns vertical stratification, both dissolved oxygen concentration temperature. Furthermore, there are mixing patterns. These events depend mainly on way connect rivers, time extent flooding, as well water levels variation. The availability nutrients, particularly phosphate, controls it is directly related with thermal stratification level column. In general, most Amazon floodplain be classified polymictic. Nevertheless, trend meromixy permanent stratification. Under conditions, other limnological variables also occurs, e.g., pH electrical conductivity. Consequently, systems high species richness result contrast lower abundance specimens.
