Summer birds reaching the margins of their range at the Cedarburg Bog and the UWM Field Station
(1982-04-01)In a previous article, Reinartz and Reinartz (1981) described the monocot and gymnosperm plants that reach their range limits at the Cedarburg Bog. The bog forest consists primarily of·white cedar (Thuja canadensis) and ... -
UWM’s first PhD in botany awarded for study of Cedarburg Bog
(1969-04-01)Thomas F. Grittinger's thesis, entitled "Vegetational Patterns and Edaphic Relationships in Cedarburg Bog," summarized for the first time we now have a large amount of information about the variety and detailed composition ... -
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, ... -
Aquatic Oligochaeta of Mud Lake, and its inlet and outlet stream
(1981-10-01)Aquatic invertebrates of Wisconsin have been studied extensively, but until recently, little work has been done with aquatic oligochaetes (segmented worms). Much of the previous work was primarily concerned with the tubificid ... -
Vascular plants near the margins of their range in Cedarburg Bog. Part 1. Gymnosperms and Monocots
(1981-10-01)Marginal populations are those located at the extreme or periphery of a species' range. In the context of this paper, marginal populations refer to a geographical periphery rather than to possible ecological margins. A ... -
Volunteer urban vegetation of Racine, Wisconsin
(1981-04-01)We have only meagre knowledge of the composition and the functions performed by vegetation in Wisconsin cities. The records of the U.S. Government Land Survey conducted in the 1830s provide information on the presettlement ... -
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 ... -
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 ... -
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 ... -
Primary production in wild and cultivated cranberries
(1980-10-01)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 ... -
Seasonal activity patterns in the bat community at Neda Mine
(1980-10-01)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 ... -
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 ... -
A 24-hour radiation budget at a high-grass marsh in early winter
(1969-04-01)As with others of the numerous physical factors forming the nonliving environment of terrestrial ecosystems, the upward and downward exchanges of the fluxes of solar (short-wave) and terrestrial (long-wave) radiation often ... -
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 ... -
Terrestrial Gastropods at the UWM Cedar-Sauk Field Station
(1980-04-01)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 ... -
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 ... -
Dragonflies at the UWM Cedar-Sauk Field Station
(1979-10-01)When visitors and classes utilize the Field Station facilities during the summer months, they seldom fail to notice dragonflies coursing the old fields or hawking mosquitoes over the little ponds. Their beauty and strong ... -
Salt and Milwaukee street trees
(1979-04-01)Many trees are not well-adapted to the rigors of urban life. Some are highly susceptible to the effects of S02. Others, such as the oaks, grow too slowly while cottonwood and horse chestnut for example, good city trees, ... -
Sex identification in Black-capped Chickadees
(1979-04-01)At the UWM Field Station we have been banding chickadees since 1965, and color banding since 1967. Since 1970, I have conducted an intensive study of the population ecology of this species involving observations of the ... -
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 ...
