The portion of the Steepbank River which cuts through the Athabasca oil sands deposit supported a less diverse benthic invertebrate community than did upstream areas. The variety and relative abundance of Plecoptera and Trichoptera were consistently lower in the area of oil sand exposure. As a substrate for benthic invertebrates, oil sand appears to be analogous to bedrock, supporting about 60% as many animals per unit area as adjacent rubble substrates. Burrowingand negatively phototropicorganisms were significantly less abundant on oil sand than on rubble. When high discharge of the Athabasca River flooded a riffle to form a pool near the mouth of the Steepbank, rheophilic forms, such as Barfis and Sin~uliutnw, e!-e largely eliminated from the rime and benthic standing stocks were reduced by about 50%. The invertebrate community recovered quickly after rifRe conditions returned.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><custom2><style face="normal" font="default" size="100%">Steepbank River, Athabasca River, Athabasca Oil Sands Region (AOSR), Fort McMurray</style></custom2><custom3><style face="normal" font="default" size="100%">http://www.worldcat.org/oclc/4635243639</style></custom3><custom4><style face="normal" font="default" size="100%">OSEMB</style></custom4></record></records></xml>
