The Beech Line In Northwestern Indiana, John E. Potzger, Carl O. Keller
The Beech Line In Northwestern Indiana, John E. Potzger, Carl O. Keller
Butler University Botanical Studies
An Indiana beech is without doubt one of the most sensitive indicators of decline in mesphytism in habitat. In the rugged areas of the state it marks the borders between moist northfacing slopes and more xeric south-facing slopes. This was shown by Potzger, Potzger and Friesner for the southern as well as for the eastern part of Indiana. Beech also records the effects which the increase of steepness of slope has on the usual more mesic conditions of north-facing slopes. This characteristic of the species suggested a study of the forests along the eastern periphery of our Indiana prairie area …
Characteristics Of The Original Vegetation In Some Prairie Counties Of Indiana, Dean Finley, John E. Potzger
Characteristics Of The Original Vegetation In Some Prairie Counties Of Indiana, Dean Finley, John E. Potzger
Butler University Botanical Studies
During the century since civilized man brought great change to the natural vegetation of Indiana by lumbering and farming, the prairie suffered perhaps more than the forest. Agriculture and drainage modified these habitats greatly. An attempt is therefore made to reconstruct the pattern of the original distribution of grasslands in Indiana. Rohr and Potzger described and discussed three northwestern Indiana prairie counties and the present study concerns itself with the prairie-influenced counties to the south and east of those described previously. In the five counties presented in this study the mesophytic forest was almost entirely inhibited and the most favorable …
The Cultivation Of Endamoeba Histolytica And The In-Vitro Chemotherapeutic Testing Of Amebacides, Maurice E. Callender
The Cultivation Of Endamoeba Histolytica And The In-Vitro Chemotherapeutic Testing Of Amebacides, Maurice E. Callender
Butler University Botanical Studies
Endamoeba histolytica is the casual organism of the disease, amebiasis. Global distribution of high incidence makes this protozoan infection an enormous public health and economic problem. Cultural behavior and the ensuing search for effective chemotherapeutic agents has stimulated widespread interest in the parasitology and associated bacteriology of this organism.
The Pioneer Period In The Study Of Indiana Vascular Flora, Ray C. Friesner
The Pioneer Period In The Study Of Indiana Vascular Flora, Ray C. Friesner
Butler University Botanical Studies
The earliest scientific work on Indiana vascular flora was done by non-resident travelling naturalists. Andre Michaux, born in Satory near Versailles, France, March 7, 1746, spent ten years in North America, 1786-1796, during which time he travelled from Hudson's Bay to Florida and from the Atlantic to the Mississippi River, and collected many species of plants. This collection contained about 20 species taken from Indiana on a trip across the state from Louisville to Vincennes in August 1795. Four day swere required for the trip of 125 miles. In commenting on this trip he writes, "Of all the journeys I …
"Clapophora Balls" Collected In Steuben County, Indiana, Fay Kenoyer Daily
"Clapophora Balls" Collected In Steuben County, Indiana, Fay Kenoyer Daily
Butler University Botanical Studies
On June 17, 1951, W. A. Daily and the author found some "Cladophora balls" washed out on shore and in the shallow water of Long Lake in the northwestern part of Steuben County, Indiana. These are hemispherical growths about one and one-half to two centimeters in diameter and are formed from intertwined algal filaments of a felt-like nature.
Correlation Of Elongation In Primary And Secondary Branches Of Pinus Resinosa, Ray C. Friesner, J. Johanna Jones
Correlation Of Elongation In Primary And Secondary Branches Of Pinus Resinosa, Ray C. Friesner, J. Johanna Jones
Butler University Botanical Studies
In a previous paper dealing with duration, rate, and magnitude of elongation of primary, secondary, and tertiary axes in two trees of P. resinosa and one of P. strobus, it was found that: (1) Elongation began at approximately the same time on all branches over the entire contour of the tree. (2) Primary axes showed greater total and higher daily rate of elongation than was shown in any of the secondary or tertiary axes in each of the 3 trees studied. (3) Secondary axes exhibited successively shorter total elongation, shorter duration of growth and slower daily growth rate from …
The Effect Of Certain Bacteria Upon The Growth Of Trichomonas Vaginalis In Vitro, John F. Lawlis Jr.
The Effect Of Certain Bacteria Upon The Growth Of Trichomonas Vaginalis In Vitro, John F. Lawlis Jr.
Butler University Botanical Studies
Trichomonas vaginalis was discovered by Donne in 1837, and for it he established the genus Trichomonas. It is, therefore, the type species of the genus. The organism is a flagellate protozoon. Measurements vary according to the age of the organism, from 18 x 6 microns to 26 x 16 microns. usually there are four anterior flagella and an axostyle protruding from the posterior end. An undulating membrane attached to the anterior end reaches back approximately one-half the langth of the organism. Recent authorities who have carefully studied the trichomonads parasitic in man, believe that T. buccalis and T. hominis are …
The Flora Of The Shades State Park, Indiana, And The Geographical Distribution Of The Species, Jack Mccormick
The Flora Of The Shades State Park, Indiana, And The Geographical Distribution Of The Species, Jack Mccormick
Butler University Botanical Studies
The great number of deeds issued in west-central Indiana within a few years of the completion of the original land survey of 1820 justifies the supposition that the fertile till-soils of the region were an alluring indemnification for the hardships necessarily borne by the first colonists. The fertility of the land, however, was concomitantly to result in the decimation of the forest-covered acres of that portion of the State within half a century. Record (40) in a resume of forest conditions in Montgomery County, Indiana, related that, "Trees and saplings were cut and their trunks were made into corduroy roads. …
The Phytoplankton Of The J. W. Frisz Memorial Lagoon, Shades State Park, Indiana, William A. Daily, Jack Mccormick
The Phytoplankton Of The J. W. Frisz Memorial Lagoon, Shades State Park, Indiana, William A. Daily, Jack Mccormick
Butler University Botanical Studies
Plankton net collections were made from the J. W. Frisz Memorial Lagoon in the Shades State Park, Montgomery County, at various intervals of time from June 12, 1951 until April 19, 1952. Most of the collections were made by jack McCormick, several by Jay D. Gilliland of Waveland, Indiana, and a few by W. A. Daily.
The thirty-seven year old artificial lagoon has an area of approximately three acres and a maximum depth of eighteen feet. It has been well stocked with game fish, but higher aquatic plants are scarce.

A Synopsis Of The Coccoid Myxophyceae, Francis Drouet, William A. Daily
Butler University Botanical Studies
During the past ten years we have examined large numbers of specimens of this group in the field and in American and European herbaria. Most of the more than one thousand type specimens involved in the nomenclature were found and studied. Many of these proved to be representatives of the twenty-eight species listed here; the remainder are material of Chlorophyceae, Rhodophyceae, bacteria, fungi, and other plants and animals. The following synopsis and keys are offered as a summary of the chief morphological features of the various taxa. It is hoped that a detailed revision, complete with synonymy and lists of …
A Five-Acre Forest Survey At Shades State Park (Indiana). A Study Of Sampling Methods, Charles L. Trotter
A Five-Acre Forest Survey At Shades State Park (Indiana). A Study Of Sampling Methods, Charles L. Trotter
Butler University Botanical Studies
Various methods have been used to represent the vegetation of a given area on the printed page. In dealing with an area as vast as a forest, only a representative sample of the entire vegetation can be studied conveniently. Therefore sampling methods used must be extensive enough to include at least all the important species in the woods that would be included if the entire forest could be tabulated. A sampling method would show with reasonable accuracy a representation of the number of species present, abundance, stem sizes, and the regularity of their distribution.
It is the purpose of this …
A Survey Of Fifteen Forest Stands In The Early Wisconsin Drift Plain Of Indiana, Johanna Jones
A Survey Of Fifteen Forest Stands In The Early Wisconsin Drift Plain Of Indiana, Johanna Jones
Butler University Botanical Studies
The fifteen stands presented in this paper were studied to determine present-day forest composition on the Early Wisconsin Drift Plain. This geological region is an area of good farmland and consequently has relatively smaller forested area than other botanical areas of the state. For this reason it has not been given much detailed study in the past.
