Entomological Studies At The Uwm Field Station, Eugene L. Lange
Entomological Studies At The Uwm Field Station, Eugene L. Lange
Field Station Bulletins
Although the invertebrate fauna represents the greatest number of species and individuals within most animal communities, little work on them has been done at the UWM Field Station. Most of the invertebrate work which has been done used insects, which are the largest class of animals. This reflects the orientation of the invertebrate zoologists at UWM towards the Center for Great Lakes Studies and the lack of an entomologist orientated to field work. This report is a statement of where we stand at the Field Station as far as past entomological research is concerned and where we are going in …

Many natural areas in Wisconsin have been preserved by the state legislature, acting through the Scientific Areas Preservation Council, and by public and private organizations such as the Nature Conservancy. The Field Station's beech-maple woods and Cedarburg Bog are good examples. Once a natural area has been preserved, decisions must be made about how to maintain or manage it. Management is defined as any activity directed toward maintaining a given condition in plant and/or animal populations and/or habitats in accordance with the conservation plan for an area (Leopold, et. aI., 1963). Since many biological communities are constantly changing due to …
The Effects Of An Altered Photoperiod Upon The Migratory Orientation In The White-Throated Sparrow (Zonoirichia Albicollis), Larry J. Miller, Charles M. Weise

A variety of cues are available that a nocturnal migratory bird might use to orient during its journey. Perhaps the best established is their use of the information available in the celestial sky. But how much information do they gain? Experiments have shown that the apparent nightly movement of the stars caused by the earth's rotation aids in providing the bird a north-south axis or compass information (Emlen, 1967b; Gauthreaux, 1969). In addition, certain constellations in the northern circumpolar region are crucial for this axis determination (Emlen, 1967b). The celestial sky also changes in a regular manner with the seasons. …
Seasonal Climates At The Cedar-Sauk Field Station, David Miller
Seasonal Climates At The Cedar-Sauk Field Station, David Miller
Field Station Bulletins
The climate of the Cedar-Sauk Field Station in its annual cycle can be described in terms of (a) energy inputs and their consequences, (b) water inputs and budget, and (c) weather phenomena. All these aspects of climate express a marked seasonality between long, snowy, and cold winters, and fully developed, warm summers. Let us look first at the energy factors in its climate.
Vegetation Forest Island Edges: A Preliminary Report, Marc C. Bruner, James B. Levenson
Vegetation Forest Island Edges: A Preliminary Report, Marc C. Bruner, James B. Levenson

As the original native forest has been dissected by roads and replaced by farms or towns, the amount of forest edge relative to the area of forest interior has greatly increased. Today forest edge communities are widespread in many man-modified landscapes. However, the role the edge community plays in the regional landscape, and the extent of and variation in the edge community are relatively undefined. The purpose of this study is to determine the nature of forest edge communities. The specific objectives of the study are to: (1) quantitatively survey and assess the forest edge community; (2) determine how forest …
