Latitudinal Variation In The Relationship Between Rosette Diameter And Fate In Common Mullein (Verbascum Thapsus L.), James A. Reinartz

Field Station Bulletins

There is currently a good deal of interest in the "biennial" life history. This stems from the fact that theoretical analysis of the selective advantage of alternate life histories predicts that biennials should seldom be favored relative to annual or perennial alternatives (Hart, 1977). However biennials often appear highly successful in terms of abundance, being both common and widespread, even though they constitute only a small proportion of any flora. This paper describes the effects of latitude on the relationship between rosette diameter at the end of one growing season and a plant's fate in the next (death, continued vegetative …

Primary Production In Wild And Cultivated Cranberries, Mark Walstrom, Forest Stearns

Field Station Bulletins

Cranberries grow in many Wisconsin sphagnum bogs. One of the two species, the large cranberry, Vaccinium macrocarpon Alt., is among the few American fruit crops in cultivation. Most of the cultivated cranberries have been derived by selection from wild, and more recently from cultivated clones. Like the large cranberry, the small cranberry, Vaccinium oxycoccos L., is native to Wisconsin bogs and it, too, provides wildlife food, though it has not been selected for cultivation. This study examined the primary productivity of wild and cultivated cranberries (Wahlstrom 1979).

Seasonal Activity Patterns In The Bat Community At Neda Mine, Charles Rupprecht

Field Station Bulletins

Even though bats represent a relatively abundant, biologically fascinating and highly beneficial component of Wisconsin's wildlife, they remain poorly studied and greatly misunderstood. Accounts of the seasonal adaptive strategies of most bats are inadequate or fragmentary (Barbour and Davis 1969). Rarely have researchers investigated more than one species at a single time and place. The aim of this study was to make simultaneous comparisons by sex and species of the various adaptive strategies employed by members of the Neda Mine bat community on an annual basis.

Muskrat Population Dynamics And Vegetation Utilization: A Management Plan, Thomas R. Mccabe, Michael L. Wolfe

Aspen Bibliography

Muskrat (Ondatra zibethicus) populations are located in extensive marshes that are managed either privately or by state or federal refuge personnel. Maintenance of a balanced muskrat population is important to marsh management, therefore necessitating accurate density estimates. Feasibility of a vegetational utilization index as a reliable population indicator is being tested at Fish Springs NWR, Utah.

Wilderness Recreation Experiences: The Rawah Case, Perry J. Brown, Glenn E. Haas

Forest Management Faculty Publications

This research focused on defining wilderness recreation experiences in terms of the psychological outcomes sought by the recreational users of the Rawah Wilderness in Colorado. Information on the outcomes was used to type users so that groups seeking different experiences could be identified. From a sample of 264 people, there were five types of wilderness recreation experiences identified. Use of information on the psychological outcomes sought by recreationists and on the types of recreationists pursuing specific activity and experience opportunities is discussed. Such information would aid in the development of more specific, quantifiable, and evaluative management objectives; could provide a …

Terrestrial Gastropods At The Uwm Cedar-Sauk Field Station, Joan P. Jass

Field Station Bulletins

A base line survey of the terrestrial gastropod fauna of the UWM Field Station near Saukville was conducted from June-September 1978 to complement other faunistic surveys conducted at this locality and to increase our information on the distribution of these mollusks in southeastern Wisconsin. To date there have been very few surveys of terrestrial gastropods in southeastern Wisconsin. In this survey 2975 specimens of 20 different identities were retrieved.

Flambeau Forest Blowdown, Glenn R. Guntenspergen, Christopher Dunn, John R. Dorney

Field Station Bulletins

On July 4,1977, the 160 acre Flambeau River Forest Scientific Area was struck by a downburst of hurricane proportions (Fujita 1977) which destroyed most of the preserve. This stand had been one of the few relatively untouched old growth northern hardwood forest stands in the Upper Great Lakes region. Hemlock, yellow birch, and sugar maple are the dominant canopy tree species. The vegetation of this stand had been studied in 1967 (Anderson 1968) and 1973 (Anderson unpublished). Thus, the Flambeau River Forest Scientific Area in northern Wisconsin provides a unique opportunity to examine the changes following large scale disturbance in …

Land Use Changes In Southeastern Wisconsin: The Landscape Pattern Project, John Dorney, Forest Stearns

Field Station Bulletins

Since settlement began in the 1830's, the native forest, wetland and prairie vegetation has been replaced by pasture, cultivated fields, highways, towns and cities. Fragmentation of the forest into smaller and smaller isolated patches influences the biological diversity of the remaining patches, as well as species replacement patterns and dispersal of seed and other propagules. This drastically alters the integrity of the regional system. This study documents changes in patterns of land use and forest vegetation and investigates factors influencing these changes and the effect of the present pattern on ecosystem maintenance. This work is part of a larger study …

Behavior Of The Southern Pine Beetle On The Bark Of Host Trees During Mass Attack, Jack E. Coster, W.D. Bunt, P.C. Johnson

Faculty Publications

Twenty-two percent of the southern pine beetles, Dendroctonus frontalis Zimmermann (Coleoptera: Scolytidae), that landed on the bark during the 1st 4 days of mass attack in East Texas, eventually entered the tree. Other beetles either flew away (43%), dropped off the host (32%), or were eaten (2%). No significant difference in searching time or distance traveled was found for day of attack or beetle sex. Males spent significantly less total time on the bark than females.

Spatial Distribution Of Flying Southern Pine Beetle (Coleoptera:Scolytidae) And The Predator Thanasunus Dubius (Coleoptera:Cleridae), Jack E. Coster, Paul C. Johnson, Reed J. Reeve

Faculty Publications

Spatial dispersion patterns of flying southern pine beetles, Dendroctonus frontalis Zimm., and the clerid predator Thanasimus dubius (F.) were determined within 3 natural infestations of southern pine beetle (SPB) in eastern Texas using grids of sticky traps. There was significant positive association of the 2 insects throughout the trapping grids, although aerial population densities of the clerid were inversely related to aerial densities of SPB. Aggregation patterns were quantified using the index of patchiness (lP) and the regressions of mean crowding (m) on mean density (m). Both methods showed a highly clumped pattern for both beetle species. SPB density in …

Outlook For Timber From Mississippi’S Private Nonindustrial Forests, Steven H. Bullard, G. H. Weaver

Faculty Publications

Forestry is the dominant land use in Mississippi. Fifty-five percent of the State's total land base is commercial forest and 73 percent of this is held by private nonindustrial owners. The estimated timber harvest value for 1979 was over $550 million. Forest products were second only to soybeans in value in Mississippi's agricultural and forestry crops. The 1979 value is the fourth consecutive record harvest and represents increases in both harvest volume and product prices.

Propagation Of Quaking Aspen (Populus Tremuloides Michx.) From Root Cuttings, Karen Elizabeth Burr

Aspen Bibliography

Lateral root cuttings were collected at five quaking aspen (Populus tremuloides Michx.) clones in Larimer County, Colorado on October 2, 1977 and May 30, 1978. The October 1977 root cuttings were stored eight months in air-tight plastic bags at 0 to 4°C. On June 1, 1978 the stored (October 1977) and the fresh (May 1978) root cuttings were planted in a greenhouse propagation bench. All sprouts that developed were allowed to grow on half of the 10-cm long root cuttings randomly selected as controls. On the remaining half of the root cuttings, designated pruned, all but the tallest sprout were …
