[1] Lake ecosystems are a prime example of lentic ecosystems (lentic refers to stationary or relatively still freshwater, from the Latin lentus, which means "sluggish"), which ...

Riparian zone. A riparian area is the transition from the aquatic area to the upland area. Vegetation is expected to change from species adapted to wetter sites near the channel to species adapted to drier sites in the upland, with a mixture of species occurring in between. In this example, an assessment of riparian function would consider the ...

Freshwater biology is the scientific biological study of freshwater ecosystems and is a branch of limnology. This field seeks to understand the relationships between living ...
Introduced trout in lake ecosystems. Since the recession of the last glaciation, isolated bodies of water high in mountain crevasses have been topographically separated from fish. [1] Within Washington state a number of lakes in the Olympic and Cascade Mountains have been stocked since the early 20th century.
