The Cedar-Sauk Field Station As A Background Site For Urban-Rural Spectral Comparisons Of Direct Beam Solar Radiation In The Visible, Howard A. Bridgman
The Cedar-Sauk Field Station As A Background Site For Urban-Rural Spectral Comparisons Of Direct Beam Solar Radiation In The Visible, Howard A. Bridgman
Field Station Bulletins
The general effects of urban atmospheric pollutants on incoming solar radiation have been observed for many years. Estimates of shortwave depletion usually fall in the 15-20% range (Landsberg, 1956, p. 589), but only a few studies have concentrated on depletion across the spectrum. Such studies have generally been concentrated on absorptive effects of gases in the infrared and the ultraviolet (see Kondratyev, 1969 and Robinson, 1966 for examples). The visible spectrum has largely been ignored. Essential to a study of urban spectral depletion effects is a properly chosen rural background site for comparison purposes, free from urban influences. The results …
Wetlands In Environmental Education, Paul E. Matthiae
Wetlands In Environmental Education, Paul E. Matthiae
Field Station Bulletins
Wetlands are one of the most useful resources the environmentally oriented educator has at his disposal. They are his best teaching facility. Most wetlands allow active use. They provide rapid and easy "direct contact" study of their components. Because one can get an overall perspective, it is often easier to observe the animal populations and to sample the plant communities. Whether the wetland is a wet cattail marsh, sedge meadow, woodland swamp or acid bog the student can see it, feel it and appreciate it as a reservoir for living things. The wetland is not only easy to observe and …
Selected Physical And Chemical Properties Of An Alkaline Bog Lake, Nancy E. Liptak, Margaret Summerfield
Selected Physical And Chemical Properties Of An Alkaline Bog Lake, Nancy E. Liptak, Margaret Summerfield
Field Station Bulletins
Mud Lake is located in Ozaukee County, Wisconsin, on land adjoining the UW-Milwaukee Field Station. It is surrounded by Cedarburg Bog, the most extensive bog in southeastern Wisconsin. This lake is unusual among bog lakes in being alkaline. Some work has been done on the chemistry of acid bog lakes (Malins Smith, 1942; Gorham, 1956; Gorham and Pearsall, 1956; Hayward, 1957), but none of these authors sampled sites with pH values approximating those of Mud Lake. The primary purpose of this study was to begin a data bank of chemical analyses of Mud Lake water samples. The availability of such …
Cedarburg Bog -A National Natural Landmark, Forest Sterns, Diane Ringger
Cedarburg Bog -A National Natural Landmark, Forest Sterns, Diane Ringger
Field Station Bulletins
The Cedarburg Bog and adjoining upland beech woods were designated, with nine other Wisconsin locations, as National Natural Landmarks. The other sites are the Wyalusing Hardwood Forest in Grant County, Summerton Bog in Marquette County, the Kakagon Sloughs in Ashland County, Abraham's Woods in Green County, Spruce Lake Bog in Fond du Lac County, the Flambeau River Hardwood Forest in Sawyer County, the Finnerud Pine Forest in Oneida County, the Chippewa River Bottoms in Buffalo County and the Chiwaukee Prairie in Kenosha County. Previously, the Ridges Sanctuary in Door County was the only Wisconsin site included.
A Study Of Aquatic Hyphomycetes Of Southeastern Wisconsin, John W. Baxter, Juanita Bronaugh
A Study Of Aquatic Hyphomycetes Of Southeastern Wisconsin, John W. Baxter, Juanita Bronaugh
Field Station Bulletins
This paper presents a portion of the results of a distributional and ecological study of aquatic Hyphomycetes in seven counties of southeastern Wisconsin. Results of the water chemistry studies and laboratory studies on the physiology of these fungi will be published separately in Mycopathologia et Mycologia Applicata. Part of this research was supported by a grant from the Graduate Faculty Research Committee. In the present investigation 28 species, representing 21 genera, were found growing on submerged decaying leaves in streams, lakes and bogs. Three previously undescribed species were found as loose spores in foam samples from Cedar Creek and Sauk …
Dispersal Movements Of Juvenile Black-Capped Chickadees, John R. Meyer, Charles M. Weise
Dispersal Movements Of Juvenile Black-Capped Chickadees, John R. Meyer, Charles M. Weise
Field Station Bulletins
To learn more about Chickadee dispersal this study was undertaken from the summer of 1970 through the summer of 1973, involving the color-banded population of Black-capped Chickadees at the UW-M Cedar-Sauk Field Station described by Weise (1971). The most intensively studied birds were located in about 26 hectares of upland beech-maple forest and about 30 hectares of the cedar-tamarack bog forest at and immediately surrounding the Field Station. The territories of the breeding pairs in these areas were mapped, and as many nests as possible were located. The development of the young in accessible nests was followed, and just before …
