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.

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 …

Fish And Wildlife Mitigation Report : Dickey-Lincoln School Lakes Project, Maine, New England Division, Corps Of Engineers, U. S. Army Engineer Division

Dickey-Lincoln School Lakes Project

The Dickey Lincoln School Lakes Project is a proposed multipurpose project located on the upper reaches of the St. John River in Aroostook County, Maine. Development would consist of two dams with associated reservoirs and hydroelectric generating facilities, five dikes and transmission lines. A more detailed description of the proposed project and its associated impacts is contained within the Revised Draft Environmental Impact Statement for the proposed project.

A Post-Impoundment Investigation Of The Beech Fork Drainage Basin, Twelvepole Creek, Wayne And Cabell Counties, West Virginia, Donald Borda

Theses, Dissertations and Capstones

Fish populations were collected at six stations by means of electrofishing to determine the composition after impoundment. A total of 748 fishes weighing about 9 pounds (4 kg) were collected. Seven families representing 31 species were collected and categorized as game, forage and rough fishes. Game fishes made up 9.1 percent of the total number and 22.3 percent of the total weight; forage fishes 83.0 percent by number and 29.7 percent by weight. The average standing crop was 15 pounds per acre.

Benthic invertebrates were collected at six stations by means of a bottom dredge. A total of 1535 specimens …
