Labrador tea (Ledum groelandicum) in the Cedarburg Bog
(1985-04-01)The Labrador tea population in the Cedarburg Bog is a southern outlyer from its more northerly range and is disjunct by at least 40 miles from the nearest population. The discovery of Labrador tea in the Bog raises to 11 ... -
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(1980-04-01)Since settlement began in the 1830's, the native forest, wetland and prairie vegetation has been replaced by pasture, cultivated fields, highways, towns and cities.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. ... -
Life cycle patterns in Wisconsin spiders
(1995-10-01)Five life cycle patterns in spiders are described and examples given. The most common pattern, maturation and mating in spring and early summer, is elaborated with a detailed description of the seasonal development of ... -
Long-term population fluctuations of small mammals at the UWM Field Station
(1988-04-01)Population sizes of four small mammals, Peromyscus leucopus, Microtus pennsylvanicus, Blarina brevicauda, and Sorex cinereus, were monitored for over twenty years at the UWM Field Station. P. leucopus had moderate fluctuations ... -
Long-term population trends in songbirds: Evidence from a general netting program
(1988-04-01)A one-day-a-week general bird-netting operation has been conducted each autumn since 1965 at the UWM Field Station. Overall results for 23 years are presented, on a species by species basis. The 101 species captured were ... -
Microclimate weather data for 1978 and 1979 at the University of Wisconsin-Milwaukee Field Station
(1981-04-01)The UWM Field Station has measured precipitation, temperature, relative humidity, wind direction and speed, and barometric pressure continuously since December 29, 1969. These data were recorded at three weather stations ... -
Microorganisms in Milwaukee rivers
(1981-04-01)Fecal coliform bacteria have long been used as indicators of water pollution (Standard Methods, 1976). However, factors that influence the coliform population in natural water bodies may alter the relationships between the ... -
Mineral cycling and productivity in an upland deciduous forest: soils and methods
(1975-10-01)This study was designed to improve our understanding of the dynamics of the upland forest and of the productivity of Wisconsin forest communities. Data were collected to quantify the biological cycling of nutrients, nutrient ... -
Mycological research at the Field Station
(1971-04-01)During the past three years, several mycological research projects have been conducted partially at the Field Station or have used research material obtained at the Station. These include a study of cellulose-digesting ... -
Natural Landscaping Bill (AB 348)
(1975-04-01)Native plants are making a comeback in Wisconsin, thanks to the growing number of homeowners who are switching to "natural landscaping". Many parks are also preserving or restoring areas with native plant communities, and ... -
Natural tree reproduction in urban environments
(1985-04-01)Three contrasting urban areas in Milwaukee County were sampled to determine the tree species reproducing and the habitats in which seedlings become established. Habitats most favorable for seedling establishment were shrub ... -
Notes on the milliped Pleuroloma flavipes (Polydesmida: Xystodesmidae) in Wisconsin
(1996-10-01)The milliped Pleuroloma flavipes Rafinesque 1820 is one of the more widespread and better known North American millipeds. During the course of recent studies in Wisconsin, we have had opportunities to examine museum specimens ... -
Notes on two species of plants at the margins of their ranges in Cedarburg Bog
(1983-10-01)In June 1983 two large patches of Fringed Polygala were found in the Cedar-Tamarack woods at the north end of Cedarburg Bog. These patches had obviously been established for a number of years but the species had never ... -

Oak island dynamics in Southeastern Wisconsin
(1979-04-01)The oak forests of southeastern Wisconsin appear relatively consistent in species composition and probably have shown little change in this regard since European settlement, perhaps because they were originally forest ... -
Patterns of seedling establishment in an old field
(1981-10-01)Within 100 years after settlement began (ca. 1830), most forest land in the Milwaukee area had been influenced by agriculture. When the land was cleared for cultivation, trees were occasionally left along property boundaries, ...
