The Diatom Flora Of The Red Lake Peatland, Minnesota, Thomas P. Pienkowski, Daniel E. Wujek
Journal of the Minnesota Academy of Science
Diatoms collected from three transects in the Red Lake Peatland occur in characteristic assemblages. One hundred two taxa were observed from 26 sample sites, with Eunotia exigua and Pinnularia rupestris the most dominant species. Clustering indicated three peatland types were present: rich fen, transitional and poor fen, and bog.

Northern And Southern Brook Lampreys (Ichthyomyzon Fossor And I. Gagei) In Minnesota, Philip A. Cochran, Timothy C. Pettinelli
Journal of the Minnesota Academy of Science
ABSTRACT - The presence of two species of brook lampreys, genus lchtbyomyzon, in Minnesota was confirmed. The northern brook lamprey (1 f ossor) occurs in the Blackhoof River of the lake Superior drainage. The southern brook lamprey (1 gagei)was found in the St. Croix River drainage above Taylors Falls. At least three microhabitats are used by 1 gagei during its life cycle. Adults prior to spawning are found in crevices beneath boulders in deep, fast water; spawning is associated with gravel substrate at the head of riffies; and larvae burrow in fine substrate in quiet water. The reproductive biology of …
