Factors influencing germination of six wetland Cyperaceae
(1997-04-01)In order to determine factors which may affect the differential seed germination of six members of the Cyperaceae which occur together in newly revegetated sedge meadow, seeds were tested for germ inability at three storage ... -
Female dominance among Purple Finches (Carpodacus purpureus) in winter flocks
(1987-10-01)The dominance of females over males in winter flocks is rare. In this paper, I report on female dominance over males in winter flocks of Purple Finches (Carpodacus purpureus). Females won nearly all observed intersexual ... -
Flambeau Forest Blowdown
(1980-04-01)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 ... -
Flowering phenology along the UWM Field Station boardwalk in the Cedarburg Bog
(1993-10-01)Flowering phenology of 254 plant species was studied over eight growing seasons between 1984 and 1993. Most of the phonological observations were made along the Field Station's boardwalk in the Cedarburg Bog. We report on ... -

Fungal flora of Southeastern Wisconsin
(1984-10-01)Since its reorganization in 1981, one goal of the Wisconsin Mycological Society has been a comprehensive long-term survey of fleshy and other fungi of southeastern Wisconsin. Over a period of years, random collections are ... -
Fungi at the Field Station
(1970-10-01)The UWM Field Station now has a mycological reference collection, for use in identifying fungi of the area. Botanists and zoologists doing research at the Field Station will find the collection useful. It can also be used ... -
Glossy buckthorn (Rhamnus frangula), a threat to the vegetation of the Cedarburg Bog
(1988-10-01)Glossy buckthorn (Rhamnus frangula) is a shrub or small tree which is a native of Eurasia, introduced to North America about the mid-nineteenth century. Escaped from cultivation, Rhamnus frangula is rapidly becoming a ... -
Goldenrods
(1968-10-01)The Goldenrods, with their abundance and diversity, produce one of the most brilliant natural wildflower displays in our area from mid-August to November. In North America there are about one hundred species of these plants ... -
Hollies in Wisconsin
(1970-10-01)With the coming of the winter season botanical interests are directed chiefly toward yuletide plants, one of which is the holly. The species most commonly used in wreaths and decorations is the English Holly (Ilex aquifolium ... -
In Quest of the Elusive Ovenbird
(1968-10-01)The Ovenbird was selected for intensive study at the UWM Field Station for a variety of reasons. First, it is closely adapted in all respects-morphological, physiological, behavioral- to the upland forest environment, ... -
Influence of forest openings on climate
(1972-10-01)Data presented in this paper were obtained during a five year study by the U.S. Forest Service (Ringger, 1972). This study, done in a hardwood stand in Forest County, Wisconsin sought to determine the effect of opening ... -
Insectivorous plants in Cedarburg Bog
(1970-04-01)Bogs, with their poorly drained organic soils, high water tables, low mineral content and cool sluggish water, offer unique habitats for a variety of unusual plants of which the insectivorous ones are especially interesting. ... -
Island biogeography in Southeastern Wisconsin: a progress report.
(1975-04-01)Ecosystems develop as a result of interactions between the biotic and abiotic components in the environment. Natural systems are diverse and stable when interactions between the community and the supersystem are in balance. ... -
Labrador tea (Ledum groelandicum) in the Cedarburg Bog

Land use changes in Southeastern Wisconsin: The landscape pattern project
(1980-04-01)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 ... -
Landscape patterns and forest island interactions
(1975-10-01)On March 18, the Field Station welcomed faculty and graduate students involved in the Landscape Pattern Analysis project. This study has both theoretical and practical objectives. The theoretical problems are concerned ... -
Latitudinal variation in the relationship between rosette diameter and fate in common mullein (Verbascum thapsus L.)
(1980-10-01)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 ... -
Leachable Phosphorus Levels of Urban Street Trees: Contributions to Urban Runoff
(1979-10-01)Intelligent environmental management of urban areas depends upon a thorough understanding of urban ecosystem properties, such as structure, energy flow and materials cycles. This report examines the phosphorous cycle in ... -
Life cycle information from a Wisconsin poplation of Porcellio spinicoris, the dark-headed isopod
(1991-10-01)Detailed life cycle information is lacking for Wisconsin terrestrial isopod crustaceans. We measured head-widths of a local population of Porcellio spinicornis and compiled data on size frequencies, sex ratio and gravidity. ...
