Organisms studied

A rock-scrubbing sampling technique was
used to collect samples at several different stations, with two
replicates at each station on three different dates. The same
sampling procedure was used for all dates. The stations were measured
relative to the site of the dripper ("-" = upstream of the dripper).
The samples were preserved in ethanol then picked, sorted, counted,
and measured in Duluth using a digitizing pad.

Notes: *** All insect numbers are larval counts unless noted otherwise. ***
