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 …
A Management Plan For A Swamp Forest Based On Vegetation Analysis, Bonnie Swartz
A Management Plan For A Swamp Forest Based On Vegetation Analysis, Bonnie Swartz
Field Station Bulletins
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
The Effects Of An Altered Photoperiod Upon The Migratory Orientation In The White-Throated Sparrow (Zonoirichia Albicollis), Larry J. Miller, Charles M. Weise
Field Station Bulletins
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
Field Station Bulletins
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 …

Dickey-Lincoln School Lakes Project
Throughout this report, the following naming conventions will be used: the study area is the region of the Saint John River from Fort Kent to Ninemile Bridge and the drainage areas of all Saint John tributaries between Lincoln School and Ninemile Bridge within the United States, excluding the Allagash River drainage; the Dickey Lake Area is that region which would be inundated by the proposed Dickey Dam and the drainage areas of all rivers and streams (excluding the Saint John River) flowing into that proposed reservoir; the Lincoln School Reservoir area is that region which would be inundated by the …

Final Report On The Recreation Plan For Dickey-Lincoln School Lakes Project, Maine : Prepared For The Corps Of Engineers, New England Division, Northern Maine Regional Planning Commission, Land Use Consultants, Inc
Dickey-Lincoln School Lakes Project
The purpose of this report is to evaluate and describe the existing recreational use and resources of the project area and the encompassing study area and to project the future use of those resources both with and without the Dickey-Lincoln School Lakes Project. This study develops and evaluates a concept plan for the recreation potential of the Dickey-Lincoln School project and assesses the recreational impact of this recommended concept plan.
Visual Detection Of Cryptic Prey By Blue Jays (Cyanocitta Cristata), Alexandra T. Pietrewicz, Alan Kamil
Visual Detection Of Cryptic Prey By Blue Jays (Cyanocitta Cristata), Alexandra T. Pietrewicz, Alan Kamil
Avian Cognition Papers
Blue jays learned to respond differentially to the presence or absence of Catocala moths in slides. This detection of the moths by the jays was affected by the background upon which the moth was placed and its body orientation, thus providing an objective measure of crypticity. These procedures are useful for the study of visual detection of prey.
