Abstract: This is a Kuparuk River rock- scrubbing. The insects are brachycentrus. The file simply lists the length of each insect measured, as well as when and where along the river it was captured. Only the actual measurements of the insects are listed, for example, if there wasn't a particular insect found from a replicate at a station, then that station isn't listed either. This file is for brachycentrus.

Organisms studied

A rock-scrubbing technique was used to collect
samples at eight different stations (-1000m, -500m, -400m, -100m, 1000m,
1400m, 2000m, and 2500m), with two replicates at each bottom scrub
station, on three different dates. The same sampling procedure was used
for each date. The stations were measured relative to the site of the
The samples were preserved in ethanol then picked, sorted, counted,
and measured in Duluth using a digitizing pad.
