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

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

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

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

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 …

Colorado Deer Hunting Experiences, Perry J. Brown, Jacob Hautaluoma, S. Morton Mcphail

Forest Management Faculty Publications

Those responsible for managing environmental resources, like big game, have often posed questions regarding how best to manage and allocate the resource to “provide benefits to people.” One approach to obtaining information for answering these questions is based on consumer behavior concepts and research.

Our consumer-oriented approach to deriving management information for environmental resources, particularly game and other recreational resources, rests on ideas conceptualized by Wagar (1966) and having their theoretical base in psychology’s expectancy-value theory (Lawler 1973). The general theoretical orientation we follow is described in Driver and Brown (1975). We also acknowledge a debt to the multiple satisfactions …

The primary impact area of the proposed project (project area) includes the St. John River watershed upstream of the proposed damsites to the confluence of Nine-mile Brook. The area is bounded by the watershed divide with the Allagash River on the east and the Canadian Border on the west.

Dickey-Lincoln School Lakes Project Environmental Impact Statement: Appendix C: Social And Economic Assessment, Edward C. Jordan, Roger Creighton

Dickey-Lincoln School Lakes Project

The purpose of this assessment of the social and economic impact of implementing the Dickey-Lincoln School Lakes Project, therefore, is not to flatly predict impacts. Rather, the intent is to provide information and judgments which can help people recognize the potential for changes and take appropriate steps to prepare for, accommodate, and adjust to those changes. Thus we hope that this report's success will be measured by how well it provides information with which local citizens and all others involved in this project can proceed with their planning and decision-making processes.

Aggregation Of The Southern Pine Beetle In Response To Attractive Host Trees, Jack E. Coster, T.L. Payne, E.R. Hart, L.J. Edson

Faculty Publications

Dendroctonus frontalis Zimmerman were attracted to shortleaf pines, Pinus echinata MilL, using infested shortleaf pine bolts. Response was monitored during the ensuing mass attack period by the use of sticky traps suspended along the tree boles. Uninfested host materials or host materials containing only male beetles did not elicit mass attack of trees. Female beetles either alone or in combination with males, usually stimulated mass attack within 24 h. Traps at 3-4 m above the ground caught the greatest number (26.7%) of beetles. Trap catches peaked on the 3rd day of attack and declined rapidly thereafter. Daily flight activity was …

Distribution Of Some Predators And Parasites Of The Southern Pine Beetle In Two Species Of Pine, Jack E. Coster, Catherine Stein

Faculty Publications

Southern pine beetle, Dendroctonus frontalis Zimmerman, and its natural insect enemies were reared from infested loblolly pines, Pinus taeda L., and shortleaf pines, P. echinata Mill. Southern pine beetle broods were most dense during spring (Mar.-May) and least dense in late summer. Populations were higher in late winter than in midsummer. There were no differences in beetle densities between the pine species. Twelve predators and 9 parasites comprised ca. 99% of the natural enemy complex.

Total density of the 12 predators did not vary with either season or tree species. Total parasite density, however, was highest in midsummer, lowest in …

Site Factors Affecting Growth Of Slash Pine In The Texas Post Oak Belt, W. D. Hacker, M. Victor Bilan

Faculty Publications

A study was conducted in the Post Oak Belt of East Texas to determine which site factors affected height growth of slash pine (Pinus elliottii Engelm.). Height-age pairs were developed from stem analysis data. Nonlinear regression was implemented to develop a generalized height-age model. After curves were developed, stepwise regression was used to determine impacts of environmental variables on height growth. Environmental factors correlated with height growth included A horizon depth and those related to moisture relations including seasonal precipitation, average daily temperature, and texture of the A horizon. South. J. . Appl. For. 21(2):71-74.

Stomatal Opening, Transpiration, And Need/E Moisture In Loblolly Pine Seedlings From Two Texas Seed Sources, M. Victor Bilan, C.T. Hogan, H.B. Carter

Faculty Publications

Relationships among percentage of open stomates, transpiration, and needle moisture content in seedlings of loblolly pine of two Texas provenances were studied under changing soil moisture conditions. Needle moisture content correlated very well with transpiration under favorable moisture conditions, and with percentage of open stomates under soil moisture stress. Transpiration and percentage of open stomates were correlated under a wide range of moisture conditions. Foliage moisture content was still relatively high in both ecotypes when stomates closed and transpiration drastically declined. The "Lost Pines" seed source appeared to have superior ability to conserve moisture under droughty conditions by closure of …

Towards Integrated Protection From The Southern Pine Beetle, Jack E. Coster

Faculty Publications

Current southern pine beetle ( Dendroctonus frontalis Zimm.) control depends heavily upon direct approaches having short-term payoffs. Chemical or physical tactics have fidled to check epidemics in the Gulf South. A major challenge lies in developing and using indirect methods for managing this pest. Promotion of stand resistance and biotic agents, and manipulation of stand density and cutting practices, hold prospect for reducing the incidence and severity of beetle-caused losses.

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.
