Hollies In Wisconsin, Peter J. Salamun
Hollies In Wisconsin, Peter J. Salamun
Field Station Bulletins
With the coming of the winter season botanical interests are directed chiefly toward yuletide plants, one of which is the holly. The species most commonly used in wreaths and decorations is the English Holly (Ilex aquifolium L.); however, many people are unaware that a number of native holly species are found in eastern North America and two of them occur in Wisconsin. Unfortunately, the Wisconsin representatives are deciduous shrubs and not suitable for Christmas decorations. Although' of no value to us for the holiday season, their fruits are eaten by overwintering birds and squirrels, hence they may be considered as …
Some Bog Denizens, G W. Prescott
Some Bog Denizens, G W. Prescott
Field Station Bulletins
Tucked away in the bogs and swamps of Wisconsin, and in similar habitats throughout the world, thrive a myriad of unicellular plants known as Desmids. They are among the most aesthetic of all microorganisms and vie with the glassywalled Diatoms as "Jewel Plants." If it were not for the inquisitive biologist and the students of the microscopic cosmos, Desmids well might exist unnoticed. For although they have highly intriguing biological features they play no role in water spoilage problems, nor are they important in the food cycle of aquatic animals. Hence they do not attract attention nor invite the condemnations …
Fungi At The Field Station, John W. Baxter
Fungi At The Field Station, John W. Baxter
Field Station Bulletins
The UWM Field Station now has a mycological reference collection, for use in identifying fungi of the area. Botanists and zoologists doing research at the Field Station will find the collection useful. It can also be used by visiting groups who have some interest in identifying the more conspicuous fungi that are likely to be seen during a tour of the area.
Insectivorous Plants In Cedarburg Bog, Peter J. Salamun
Insectivorous Plants In Cedarburg Bog, Peter J. Salamun
Field Station Bulletins
Bogs, with their poorly drained organic soils, high water tables, low mineral content and cool sluggish water, offer unique habitats for a variety of unusual plants of which the insectivorous ones are especially interesting. These plants have one feature that separates them from others-their leaves are capable of attracting, holding and partially digesting insects. Because bogs are difficult to traverse during the warmer months of the year, and the mosquitoes are numerous, many persons have never observed these plants in their native habitats and few professional botanists have studied the nature of their physiological adaptations to this environment. A series …
The Late-Glacial And Post-Glacial History Of The Cedarburg Bog Area, Wisconsin, Norman P. Lasca
The Late-Glacial And Post-Glacial History Of The Cedarburg Bog Area, Wisconsin, Norman P. Lasca
Field Station Bulletins
Continental glaciers moving over Wisconsin four times in the last two million years sculptured the underlying Paleozoic dolomites and limestones in the Cedarburg area and deposited vast amounts of debris on the bedrock surface. Since the retreat of the Wisconsinan ice, about 12,000 years ago, mass-wasting, fluvial activity, and weathering have modified the landscape and produced the topography we see today. The Pleistocene deposits of the Cedarburg area are late Wisconsinan in age, and the earlier history of the area must be inferred from studies done in Southern Wisconsin and the surrounding states. As early as the mid-1800's mention is …
The Stadium Interstate Freeway And Cedarburg Bog, Millicent S. Ficken, Forest Stearns
The Stadium Interstate Freeway And Cedarburg Bog, Millicent S. Ficken, Forest Stearns
Field Station Bulletins
Although the initially favored corridor for the Stadium interstate freeway was adjacent to Cedarburg Bog, the highway department is now favoring a route at least a mile from the Bog. Many different individuals had written highway officials stressing the scientific, educational and recreational value of the Bog. It is appropriate that the highway officials of a state which has been a leader in preserving natural areas for scientific and educational use should show concern with preserving Cedarburg Bog as a wilderness area. A hearing about the proposed route will be held July 10 in Ozaukee County, and testimony will be …
The Fat And Weight Cycle In Wisconsin Juncos, Charles M. Weise
The Fat And Weight Cycle In Wisconsin Juncos, Charles M. Weise
Field Station Bulletins
Our study was aimed at answering three specific questions. First, do wild Juncos in Wisconsin exhibit spring premigratory fat deposition. Second, it has been reported that during the winter, fat deposits and body weights are high during cold periods and lower during warm spells: in other words fat condition is inversely temperature-dependent. Our second objective then was to get large samples of weights and fat conditions under a variety of winter weather conditions in order to test the reality of the inverse temperature-dependence claimed by others. Third, we wanted to investigate the diurnal patterns of fat deposition.
