Termites Or White Ants, Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

TERMITES are commonly but erroneously called "white ants."

Actually they are more nearly related to cockroaches than to ants, but their general appearance and subterranean habits have given strong support to the popular designation.

They may be divided into two major groups from an economic point of view, viz., wood-dwelling and earth-dwelling termites.

Grasshoppers And Locusts In Western Australia, Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

GRASSHOPPERS and locusts are among the most ancient enemies of the farmer, for they figured prominently in Biblical times, and periodically throughout the ages have devastated crops in all parts of the world.

The Romney Marsh, J A. Mallett

Journal of the Department of Agriculture, Western Australia, Series 4

THE Romney Marsh, sometimes known as the Kent, is the most popular of the British longwoel sheep breeds used in Western Australia.

Rams of this breed are widely used for mating with Merino ewes, the crossbred female progeny of the matings being in demand for subsequent mating with Downs-type rams to produce export Iambs.

Malaysian Parasites Xxxv-Xlix, W. W. Macdonald

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This is the third Study of the series from this Institute on the external and internal parasites and the biting insects of the Malaysian region. The earlier two volumes were planned and edited by Dr. J.R. Audy, and on his departure from Malaya in the middle of 1959 Mr. W. W. Macdonald continued the work which had been begun and collated and edited the papers in this present Study.

In the two previous volumes (Study No. 26, 1954 and No. 28, 1957) the emphasis was on the taxonomy of Trombiculid mites. In the present volume the emphasis has changed, and …

Notes On Scottsbluff, Nebraska, Tornadoes, 27 June 1955, Robert G. Beebe

National Oceanographic and Atmospheric Administration: Technical Reports and Related Materials

Some general characteristics of thirteen tornadoes that occurred on the afternoon of June 27, 1955 in Scottsbluff County, Nebraska, are related. Two of these caused widespread attention due to their size and their proximity to the cities of Scottsbluff and Mitchell, Nebraska. These two were photographed extensively by residents near their paths. The experience of two men directly beneath one of the two large tornadoes is related.

Biotic Succession In A Douglas Fir Forest On Saddleback Mountain (Oregon Coast Range), Jane Claire Dirks-Edmunds

Jane Claire Dirks-Edmunds Documents

This grant proposal, submitted to the National Science Foundation in 1959 by Dr. Jane Claire Dirks-Edmunds, requested funding to continue an ecological study at Saddleback Mountain. Dirks-Edmunds requested $15,570.05 to fund weekly trips with students to the site in order to collect meteorological and synecological data on the forest; she anticipated the project would last two years.

Dr. Dirks-Edmunds graduated from Linfield College in 1937; she returned to teach in the Biology department at Linfield from 1941-1974.

An Iron Fulgurite From Nebraska, C. M. Riley

Bulletin of the University of Nebraska State Museum (1924–2023)

From the time of the ancients man has been impressed with the force of lightning and its effect on the rocks at the surface of the earth. It was Saussure in 1786 who first wrote a scientific account of a true fulgurite, and a wealth of literature has been written about the subject since this time. Many unusual fulgurites have been described, some of which may not truly be the result of lightning. The iron fulgurite is a strange conical object about 3 inches high composed mainly of tiny spheres and filaments of metallic iron intermixed with a small amount …

Studies On The Microcrustacea Of Three Montane Lakes In Glacier National Park, Montana, Robert O. Megard

Biology ETDs

Grinnell Lake, Lake Josephine, and Swiftcurrent Lake, at an elevation of approximately 5,000 feet in northwestern Montana, are comparable with lakes in the montane zone defined by Pennak for lakes at elevations between 8,200 feet and 10,500 feet in the Rocky Mountains of northern Colorado. Five species of Copepoda, six Cladocera, and four Ostracoda were collected in the lakes studied. The population of microcrustacea in these lakes was most dense in or slightly above the masses of rooted aquatic vegetation growing to a height of six to 10 inches above the bottom wherever the water was between three feet and …

Chlorophyll And Productivity In A Mountain River, William J. Mcconnell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigation of primary production in streams and rivers has lagged behind similar investigations in marine and lacustrine environments. Recently, however, Odum (1956) has demonstrated methods that allow the estimation of productivity of most moving waters. For reasons discussed later in this paper, Odum's method is not satisfactory for shallow, very rapid rivers as typified by Logan River. The present investigation then was primarily an exploration of a method possibly applicable to measurement of productivity in shallow rapid rivers.

Investigations of phases of the ecology and distribution of the main contributors to primary production, the benthic algae, was a necessary corollary …

4. Social Darwinism, 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 singular impact of Darwin in fields other than biology can be attributed largely to one man, Herbert Spencer (1820- 1903). It was Spencer, not Darwin, who coined the expression "survival of the fittest." Although neglected today except by historians of the nineteenth century thought, Spencer's influence on his own time was so great that Justice Oliver Wendell Holmes was able to wonder if "any writer of English except Darwin has done so much to affect our whole way of thinking about the universe." Herbert Spencer was born into a traditionally nonconformist English family of modest means. He refused a …

The Effects Of Woodpeckers On Populations Of The Engelmann Spruce Beetle, F B. Knight

The Bark Beetles, Fuels, and Fire Bibliography

Woodpeckers have been recognized for many years as a major factor in the natural reduction of Engelmann spruce beetle populations. A means of assessing their value has been developed. Five classifications of woodpecker feeding based on woodpecker work on 225 trees were studies. An analysis of populations measurements showed a correlation between beetle survival and the woodpecker classification and the intensity of infestation in each tree. A heavy woodpecker classification resulted n very little survival at all intensities of infestation. Survival increased both with an increase in intensity of infestation and a lower woodpecker classification. The average reduction in populations …

2. The Impact Of Darwinism On Religion, 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 tremendous impact of evolution upon Western religious thought resulted in large part from the sweeping implications of the theory itself, which challenged the basic tenets of traditional dogma. It is difficult to understand the nature and intensity of the controversy that developed, however, if it is not understood that the challenge was given additional weight by the ascendency of science in the nineteenth century. In considering the influence of Darwin's findings on religion, as on other areas of thought, it should be kept in mind that the theory of evolution was presented to a world that was observing a …

1. Charles Darwin And Organic Evolution, 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

Evolution was not a new idea. The Greeks speculated on it. In the century before Darwin many different evolutionary theories were proposed, among them notable efforts by Buffon, Lamarck, and Goethe. Their common thread was the concept that the succession of biological changes in geological time represented a fact, if not a natural law. The stumbling block was for all of them, as it had been for Cuvier, the concept of fixed species, which clashed with the vision of a distant past populated with races of plants and animals now extinct. It became evident that the idea of fixed species …

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 …

5. Social Darwinism Reconsidered, 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

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 …

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. …

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 …
