Stream Classification& Abiotic Factors
![Page 2: Stream Classification & Abiotic Factors Watershed A contiguous area that is contained with an elevated ridge such that rainfall within the area flows.](https://reader036.fdocuments.us/reader036/viewer/2022081516/56649ef65503460f94c09594/html5/thumbnails/2.jpg)
Watershed
• A contiguous area that is contained with an elevated ridge such that rainfall within the area flows down and ultimately out through one point (the lowest in elevation).

Lotic Ecosystem
• Lotic ecosystems are freshwater systems with flowing water.
• Examples include rivers, streams, creeks, and brooks.
• Ambiguity of commonly used terminology has led to the “stream orders” system of classification.

Stream Orders
• 1st order streams occur where the stream originates
• 2nd order streams arise where two 1st order streams join
• The order doesn’t change where two streams of different orders come together
• 3rd order streams arise where two 2nd order streams join

Stream Ecology
• Ecology is the study of the interactions between the non-living (abiotic) and living (biotic) components of an ecosystem, and the interactions between the living components with each other.
• What are important abiotic factors that help to distinguish the low order, headwater streams, from the high order, riverine habitat?

Headwaters
• Lower order streams compose the headwaters.
• Important abiotic factors include elevation, water velocity, temperature, dissolved oxygen, and turbidity, available sunlight, substrate size, and stream width and depth.

Riverine Habitat
• Higher order streams compose the riverine habitat
• Important abiotic factors are the same as those found in the headwater streams but are generally opposite in nature
