  • Story:

    As part of the course work, a class at an upstate
    NY college collects data on streams each year. Students
    record a number of biological, chemical, and physical variables,
    including the stream name, the substrate of the stream
    (limestone (L), shale (S), or mixed (M)), the pH, the temperature
    (C), and the BCI, a measure of biological diversity.
