Freshwater ecosystems are a subset of Earth's aquatic ecosystems that include the biological communities inhabiting freshwater waterbodies such as lakes, ponds, rivers, streams, springs, bogs, and wetlands. [1] They can be contrasted with marine ecosystems, which have a much higher salinity. Freshwater habitats can be classified by different ...
Lakes and ponds experience much of the same pollution as rivers and streams, but are polluted at a quicker rate due to slower moving waters, no water flow outlets, and amount of water. [16] Standing water circulates much less than moving waters, with the deeper water layers only moving during seasonal changes twice a year. [16]
The lake sturgeon is near the southern end of its range in Arkansas, more commonly found in the Upper Midwest. [86] Pallid and shovelnose sturgeon live in large, turbid rivers of the Mississippi Alluvial Plain, including the lower Arkansas, Mississippi, and lower White rivers downstream of impoundments.

Connectivity between streams and lakes relates to the landscape drainage density, lake surface area and lake shape. [15] Other types of aquatic systems which fall within the study of limnology are estuaries. Estuaries are bodies of water classified by the interaction of a river and the ocean or sea. [13]
For natural pond conservation and development, one way to stimulate this is with general stream and river restoration. Many small rivers and streams feed into or from local ponds within the same watershed. When these rivers and streams flood and begin to meander, large numbers of natural ponds, including vernal pools and wetlands, develop. [40]
This stream operating together with its environment can be thought of as forming a river ecosystem. River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts.

a narrow channel of water that connects two larger bodies of water, and thus lies between two land masses. Stream: a body of water with a detectable current, confined within a bed and banks. Stream pool: a stretch of a river or stream in which the water is relatively deep and slow moving. Streamlet: a small stream; rivulet. [38] Subglacial lake
