(1) Longitudinal banding, but the longitudinal replacement of species is not a uniform continuous change, and special populations can reappear throughout the river.
(2) Most of the organisms have special morphological structures that adapt to the rapids habitat. It is less in plankton; the benthic organisms are more flat. Straight line shape or sucker structure; adaptable fish and microbes are abundant.
(3) The relationship with other ecosystems is complicated. On the one hand, climate, vegetation and human disturbance intensity have great influence on river ecosystems; on the other hand, river ecosystems obviously affect the formation and evolution of coastal (especially estuary, bay) ecosystems.
(4) The self-purification ability is strong, and the recovery speed is faster after being disturbed. |
