| Methods: |
A 15 minute drift sampling technique was used to collect drift samples at nine different stations (-550m, -320m, -267m, -136m, 233m, 482m, 1056m, 1370m, and 1800m) with three replicates at each station in the Oksrukuyuk Creek. Two different dates were sampled, the same procedure was used for every date, except that on 3-Jul-89 the 233m station was not sampled and on 31-Jul-89, the 1800m station was not sampled. The stations are measured relative to the future site of the new dripper. The samples were preserved in ethanol then picked, sorted, counted, and measured in Duluth using a digitizing pad. Notes: There is one sample missing from this worksheet: #2 482m from 31-July-1989. *** All insect numbers are counts of larval forms. ***
