TEMPORAL DIFFERENCES IN THE ORDERS EPHEMEROPTERA, PLECOPTERA AND TRICHOPTERA (EPT) IN OAK CREEK (BENTON COUNTY, OREGON) FOLLOWING A FLOOD DISTURBANCE
 
Taxa diversity and life histories were analyzed for the Ephemeroptera, Plecoptera and Trichoptera (EPT) community in an agricultural reach of Oak Creek (Mary's River watershed) prior to and following flooding in February of 1996. Samples collected in June of 1993 were compared to samples taken in June, 1996 and showed dominance of the genus Labiobaetis. Post-flood changes within the site included increased community evenness in association with lower abundance of and dramatic changes in EPT community composition as detected using Jaccard similarity coefficients. Temporal succession was examined by including samples taken in March and October of 1996 and considered in relation to EPT life histories.
