Effect Of Sewage Effluent On Bird Abundance And Species Composition In A Northern Minnesota Wetland, Joann M. Hanowski, Gerald J. Niemi Jan 1994

Effect Of Sewage Effluent On Bird Abundance And Species Composition In A Northern Minnesota Wetland, Joann M. Hanowski, Gerald J. Niemi

Journal of the Minnesota Academy of Science

Bird abundance was monitored before (1985 and 1987) and after (1989) sewage wastewater effluent was added to a northern Minnesota wetland. Community parameters (i.e., number of individuals and species richness) varied annually, but, overall bird communities in 1985 and 1989 were more similar to each other than they were to the 1987 community. Relative abundance of 35 bird species was unchanged between years and species abundance ranks were not different between years. Distribution of numbers of individuals (relative percent) within nesting and foraging guilds (species that have similar nesting or feeding requirements) was similar among years. Numbers of species that …


Additions And Confirmations To The Algal Flora Of Itasca State Park Ii. Diatoms From Chambers Creek, Mark B. Edlund Jan 1994

Additions And Confirmations To The Algal Flora Of Itasca State Park Ii. Diatoms From Chambers Creek, Mark B. Edlund

Journal of the Minnesota Academy of Science

A survey of the summer diatom flora of Chambers Creek, Clearwater County, Minnesota, is presented, continuing an inventory of the algal flora from Itasca State Park. Chambers Creek is a short, second-order, hardwater stream with great habitat diversity and a rich algal flora. One hundred and twenty-six diatom taxa representing 45 genera are reported, with many new reports from the park. Recent taxonomic revisions have been incorporated into this study and seven new nomenclatural combinations proposed.

Ecosystem Studies At Cedar Creek Natural History Area, Iii: Water Use Studies, A. N. Bonde, J. D. Ives, D. B. Lawrence Jan 1961

Ecosystem Studies At Cedar Creek Natural History Area, Iii: Water Use Studies, A. N. Bonde, J. D. Ives, D. B. Lawrence

Journal of the Minnesota Academy of Science

Previous articles in this series (Lawrence et al. 1957-58, 1960) have dealt with the nature of ecosystems, history of the ecosystem analysis approach, and some of the objectives and the methods that have been used at the Cedar Creek Natural History Area of the University of Minnesota and the Minnesota Academy of Science. The area, which was acquired in large part through a generous grant from the Fleischmann Foundation, is located in Anoka and Isanti Counties in east central Minnesota. The work has been generously supported by the Hill Family Foundation since the early summer of 1957.

One main objective …

The Interrelationships Of Bark Beetles And Blue-Staining Fungi In Felled Norway Pine Timber, J. G. Leach, L. W. Orr, Clyde Christensen Jan 1935

The Interrelationships Of Bark Beetles And Blue-Staining Fungi In Felled Norway Pine Timber, J. G. Leach, L. W. Orr, Clyde Christensen

Journal of the Minnesota Academy of Science

A study of two species of bark beetle (lps pini Say and I. grandicollis Eichh.) and the fungi associated with them has been made as the first part of a general investigation of the interrelations of insects and fungi in the deterioration of felled logs of Norway pine.
