Question

what are the effects of sunlight on the aquatic life inhabiting the rio grande river

Answer 1

Rivers respond to changes in mean annual flow by a period of adjustment to the new regime after which they stabilize in a form adapted to the altered conditions. Clearly reductions in flow will result in the progressive restriction of the stream to a smaller bed within the original channel with a concomitant loss of habitats for fish and other aquatic organisms. Conversely, overall increases in flow will lead to the enlargement of the river channel by erosion of former banks and other features; these, in time, should lead to an increase in habitat diversity through extension of the aquatic system. Biotic sensitivity to changes in water regimes are not limited to alterations in absolute quantity but also to the distribution of flow in time as food peaks can be moved to different times of the year or even suppressed altogether.
