3. Darwinism And The Rise Of Social Science, Robert L. Bloom, Basil L. Crapster, Harold L. Dunkelberger, Charles H. Glatfelter, Richard T. Mara, Norman E. Richardson, W. Richard Schubart
Section XV: Biology and the Rise of the Social Sciences
The two areas of the social sciences which were more stimulated by Darwin's research were anthropology and sociology. The Frenchman, Auguste Comte (1798-1857), generally regarded as the father of sociology and the originator of that term, laid the groundwork for the immediate application of the law of evolution to the study of society. Comte's conception of sociology is derived from his philosophy of history. Sharing the Enlightenment belief in progress, Comte saw history evolving through three stages. The first was the theological stage, in which men supplied supernatural explanations for the natural and social phenomena. This was followed bu what …

Section XV: Biology and the Rise of the Social Sciences
Although the contemporary reaction to the implications of evolution was generally one of long-term optimism, an antithetical reaction did exist. Seen in stark terms, evolutionary theories were depressing to those who, on religious or humanitarian grounds, found the reduction of life to an irrational and brutal struggle for existence disturbing and provocative. There was, however, an important body of thought which accepted Darwin's findings without embracing the social or ethical implications of Social Darwinism. Many who studied Darwin came to the conclusion that it was possible to concede that man is an animal, but an animal capable of moral and …

Soil Aggregation By Microorganisms Following Soil Fumigation, T. M. Mccalla, Francis A. Haskins, R. D. Curley
Soil Aggregation By Microorganisms Following Soil Fumigation, T. M. Mccalla, Francis A. Haskins, R. D. Curley
Department of Agronomy and Horticulture: Faculty Publications
The influence of autoclaving and of fumigation with eight chemical formulations upon microbial numbers in straw-amended Peorian loess and the extent to which these treatments affect the degree of aggregation brought about by subsequently introduced inocula were determined. A mixed soil flora, Stachybotrys atra and a blank inoculum consisting of sterile salt solution, were compared. Only in the autoclaved soil was a mixed soil flora inoculum consistently superior to the blank inoculum in promoting aggregation of the Peorian loess. It was found that inoculation with S. atra could greatly increase the aggregation of fumigated Peorian loess in treatments where the …

A Comparison Of The Blood Oxygen Capacity In Semi-Terrestrial And Aquatic Frogs, Francis Burke Leftwich
Master's Theses
The present investigation is a comparison of the blood oxygen capacity in three species of frogs: a semi-terrestrial form R. pippins, the meadow frog; and two aquatic forms, R. clamitans, the green frog; and R. catesbeiana, the bullfrog. The habitats or these frogs are described by Wright and Wright (1949) as follows: R. pipiens inhabits swampy marsh lands, upland backwaters, overflows, and ponds in the spring. In summer it is found in swamp lands, grassy woodlands, or in cultivated hay and grain fields. In winter it hibernates in pools or marshes. It has been found as far as …

Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson
Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson
Nebraska Game and Parks Commission: Publications
The purpose of this booklet is to provide a ready field reference for identification, sexing and aging of common game species. It has purposely been kept in simplified form, presenting only those techniques which can commonly be applied in the field and avoiding those which would require special equipment and skills. Untrained personnel should be given demonstrations of the techniques, and thereafter this reference should serve as a reminder. It is not expected that the reference could successfully be used without such demonstration. Certain of the techniques such as cloaca! examination of waterfowl may require considerable practice by the individual. …

Comparison Of Effects Of X-Ray And Thermal Neutrons On Dormant Seeds Of Barley, Maize, Mustard, And Safflower, B. H. Beard, Francis A. Haskins, C. O. Gardner
Department of Agronomy and Horticulture: Faculty Publications
Comparisons of the biological effects of X-rays and thermal neutrons on dormant seeds of barley have been made by seedling height studies, root tip cytological analyses, and cytological studies of pollen mother cells in the first generation following irradiation and by seedling mutation studies the second generation after irradiation. The results of these studies have been reported by Caldecott, Frolik and Morris (1952) and Caldecott, Beard and Gardner (1954). The objective of the research reported in this paper was to extend the comparison of these two types of radiation by studying their effects on dormant seeds of four widely different …
Research Notes: Experimental Infection With Strigoid Cercariae, Glenn L. Hoffman
Research Notes: Experimental Infection With Strigoid Cercariae, Glenn L. Hoffman
United States Fish and Wildlife Service: Publications
During the summers of 1947 and 1948 strigeoid cercariae from Carrol Lake, Wisconsin were collected and identified by the late Dr. F. G. Brooks and turned over to the writer for use in the experimental infection of frog tadpoles and various fish. It was hoped to establish or eliminate these animals as the second intermediate host. One of the 8 tested was found infective for fish, and 1 infected tadpoles. These records do not elucidate the life cycles of these worms, but it is hoped that the work may help in the future study of strigeoid cercariae.

Effect Of Time Of Cutting On Yield And Botanical Composition Of Prairie Hay In Southeastern Nebraska, Elverne C. Conard, Vincent H. Arthaud
Effect Of Time Of Cutting On Yield And Botanical Composition Of Prairie Hay In Southeastern Nebraska, Elverne C. Conard, Vincent H. Arthaud
Nebraska Agricultural Experiment Station: Historical Research Bulletins
Approximately three and one-third million acres of native prairie are harvested annually in Nebraska for hay. In the four-year period 1948-1951, the State ranked first in wild hay production with an average yield of more than two and one-quarter million tons per year. This crop is an important natural resource in Nebraska's livestock industry. Studies were initiated in 1945 to determine the effects of time of cutting on the yield and feeding value of prairie hay in southeastern Nebraska. The studies were continued through the summer of 1952 to determine the effects of different cutting treatments on the vigor and …
Joseph Pitty Couthouy (1808-64) In Texas, S. W. Geiser
Joseph Pitty Couthouy (1808-64) In Texas, S. W. Geiser
Field and Laboratory
One of the most interesting and appealing members of the scientific staff of the Wilkes Exploring Expedition around the world (1838-42) was Joseph P. Couthouy. The biographers, however, have dealt badly with him. Neither Appleton's Cyclopaedia of American Biography, nor the curiously selective Dictionary of American Biography give a sketch of his life. Nor is there one in that omnium-gatherum, the Lippincott-Thomas biographical dictionary (which can hardly be called selective, judging from some inclusions). Fragmentary accounts of him are given in various notes on the work of the Wilkes expedition; and we have early been dependent on Bouve's (1880) and …

Gustavus Wilhelm Wuerdemann (1817-59), Early Naturalist Of The U.S. Coast Survey, S. W. Geiser
Field and Laboratory
The recent appearance of Wraight & Roberts' sequicentennial historical account of the U.S. Coast & Geodetic Survey calls to mind the splendid natural-history collections that G. W. Wurdemann, tidal-observer and meteorologist, made during the years 1844 to 1859, especially in Texas, Louisiana, and Florida. As no extended biographical notice of this naturalist has appeared in the nearly one-hundred years that have passed since his death, the present note may be of interest to students of the history of scientific exploration in the early South and Southwest.

A Comparison Of The Blood Oxygen Capacity In Painted Turtles (Chrysemys Picta Schneider) And Box Turtles (Terrapene Carolina Linne), Harold J. Payne
A Comparison Of The Blood Oxygen Capacity In Painted Turtles (Chrysemys Picta Schneider) And Box Turtles (Terrapene Carolina Linne), Harold J. Payne
Master's Theses
Among factors necessary for an animal to maintain life is the presence of an oxygen carrier that will transport a sufficient quantity of oxygen necessary for respiratory metabolism. In animals whose blood contains hemoglobin, which is a pigment that loads and unloads oxygen, this carrying capacity is referred to as blood oxygen capacity. It is a measure of the amount of oxygen that will combine with whole blood when completely mixed with air. It is usually expressed in volumes per cent (ml. 02/100 ml. blood) and corrected to standard temperature and pressure.
A search of available literature revealed that there …
Studies On The Periodicity Of Certain Plankton Species Of Salem Lake, Gene A. Pratt
Studies On The Periodicity Of Certain Plankton Species Of Salem Lake, Gene A. Pratt
Theses and Dissertations
Plankton samples were taken periodically from one station in Salem Lake from the fall of 1955 through the winter of 1957. Other data including the pH, dissolved oxygen content, turbidity, brightness of day, temperature, and time of day were recorded at the time of each collection. The plankton samples were centrifuged and preserved in a 4% formalin solution. They were later examined microscopically, and density, percent density, and percent frequency calculations were made from them for ten selected species and for the five phyla which they represent.
Observations On The White-Faced Ibis, Plegadis Chihi, In Louisiana, Horace William Belknap
Observations On The White-Faced Ibis, Plegadis Chihi, In Louisiana, Horace William Belknap
LSU Historical Dissertations and Theses
The eight-month study deals with the White-faced Ibis, Plegadis chihi, in southwestern Louisiana. It affirms the absence of the closely related Glossy Ibis, Plegadis falcinellus, as a breeding bird in that area today. Data on feeding habits, social behavior, nesting cycles, and plumage changes in chihi are presented as a step toward clarifying the relationship of these two puzzling forms of ibis; but the full significance of these findings cannot be ascertained until more is known about the habits of falcinellus. The most important conclusions concern plumage changes. It is shown that published descriptions of plumage and molt in chihl …
Chemosynthetic Microorganisms In Leaching Sulfide Minerals, A. Keith Jameson
Chemosynthetic Microorganisms In Leaching Sulfide Minerals, A. Keith Jameson
Theses and Dissertations
This investigation showed that a single bacterium was capable of sulfide oxidation in exposed ore bodies. This single bacterium was isolated and characterized. It exhibited different characteristics than any previously known organism. It was found to be a chemosynthetic autotroph. An optimum nutrient concentration was determined for pyrite oxidation. The nutrient concentration was determined for pyrite oxidation. The nutrient contains only a source of phosphate and nitrogen. Urea was found to be a better source of nitrogen than ammonium sulfate which had previously been used. The effect of various organic compounds on the oxidation of pyrite was observed. Glucose and …
