Communication at the NABS Annual meeting, Keystone, 2000
(352) AN INVESTIGATION USING CANONICAL CORRESPONDENCE
ANALYSIS (CCA) OF THE ENVIRONMENTAL VARIABLES THAT SHAPE THE
PERIPHYTIC ALGAL COMMUNITY IN THE SHEYENNE RIVER, ND.

The Sheyenne River is a medium-sized river which flows through central and eastern North
Dakota. Devils Lake has been flooding for the past several years. The Army Corps of Engineers
has proposed to divert water to the Sheyenne River through an outlet. The objective of this
project was to determine the periphytic community structure before the diversion has been
completed. For three years, both artifical periphytic algal communities and water chemistry
samples were collected. This data will be analyzed using canonical correspondence analysis
(CCA). Preliminary results indicate that the community structure is responding to nitrate levels
and the amount of dissolved solids.
