Predicted climate-induced changes in the Great Lakes include increased variability in water levels, which may shift periphyton habitat. Our goal was to determine the impacts of water level changes in Lake Superior on the periphyton community assembla

Rhoicosphenia is a relatively small genus with about 30 species and 30 infraspecific varieties. Over the past decade there has been a renewed interest in describing previously undocumented diversity in Europe, Asia and North America, from fossil and

Frustulia creuzburgensis was originally assigned to the genus Navicula and later transferred to Frustulia due to its unilaterally deflected external proximal raphe ends resembling those of F. weinholdii. Unlike most members of the genus, F. creuzburg
