Occurrence And Distribution Of Invertebrates In Lower Logan River, Nancy A. Erman
Occurrence And Distribution Of Invertebrates In Lower Logan River, Nancy A. Erman
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A study of bottom invertebrates on the lower Logan River, Logan, Utah was conducted from June 1966 to July 1967. One objective was to evaluate on a qualitative and quantitative basis the invertebrate populations above and below a sewage entry in the river. Another objective was to study the year-round fluctuations in the invertebrate population.
The greatest variety of invertebrates was found in the summer. Chironomidae and Baetis were the only two groups found in abundance over the entire year.
Populations were reduced during autumn when water levels rose, and they declined even more sharply during the spring flood.

Three Physical Measurements Of Male White-Tailed Deer In West Virginia Correlated With Soil Fertility And Population Density, Charles C. Coffman
Three Physical Measurements Of Male White-Tailed Deer In West Virginia Correlated With Soil Fertility And Population Density, Charles C. Coffman
Theses, Dissertations and Capstones
Differences in the physical size of male white-tailed deer from varying parts of West Virginia were known to exist a considerable number of years before any sophisticated attempts were made to explain them. Prior to 1940, the state's deer herd had been making a slow, but increasingly steady, comeback from a period of extreme scarcity around the turn of the century. To supplement the original remaining stock, shown in Figure 1, page 2, a deer restocking program was initiated in 1923. In 1937, federal legislation, in the form of the Federal Aid to Wildlife Restoration Act, gave added support to …

West Midlands Development : Pastures For Sandplain Soils, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
TRIALS at the Badgingarra Research Station have indicated that many pasture species will grow in the West Midlands area.
Choice of the species most suited to any particular locality will be influenced by soil type, rainfall, grazing characteristics and possible ill-effects on stock.
The following species have been recommended.
Prairie Plants And Their Environment, J. E. Weaver
Prairie Plants And Their Environment, J. E. Weaver
Papers of John E. Weaver (1884–1956)
When, in 1916, the writer came to the University of Nebraska as a young instructor, he came with a background that well fitted him for studies in the field. His research in the grassland and adjoining forests of southeastern Washington and adjacent Idaho had been completed and a fine acquaintance had been made with methods of examining the prairie both above and below ground level (Weaver, 1915, 1917). Similar studies in the area between the Missouri River and the Rocky Mountains were now to be made, and these have resulted in many new investigations that are of both scientific and …

The Role Of Adventitious Reinforcement In Operant Discrimination, Alan Kamil, John W. Davenport
The Role Of Adventitious Reinforcement In Operant Discrimination, Alan Kamil, John W. Davenport
Avian Cognition Papers
Rats were trained in 2 SD-SΔ discrimination experiments in which the effects of an SD-postponement contingency during SΔ and temporal regularity of SΔ duration were assessed. Experiment I showed that discrimination is markedly facilitated by the presence of an SD-postponement contingency of either fixed or variable duration. Experiment II showed that variable-duration SΔ periods in a noncontingent schedule can also greatly enhance formation of an operant discrimination. These effects were attributed to differences in the probability of adventitious reinforcement of SΔ behavior by SD events.
Notes On Spotted Skunks (Genus Spilogale) From Western Mexico, Hugh H. Genoways, J. Knox Jones Jr.
Notes On Spotted Skunks (Genus Spilogale) From Western Mexico, Hugh H. Genoways, J. Knox Jones Jr.
University of Nebraska State Museum: Mammalogy Papers
Specimens of spotted skunks acquired from western Mexico by the Museum of Natural History at the University of Kansas in the past two decades add substantially to the knowledge of the species occurring in that region. Two specimens of the rare Spilogale pygmaea (one from Sinaloa and one from Oaxaca) are reported for the first time. Two subspecies of pygmy spotted skunk are recognized - S. p. pygmaea Thomas with type locality at Rosario, Sinaloa, and S. p. australis Hall with type locality at Acapulco, Guerrero.
The large spotted skunk, Spilogalepusorius, varies clinally in size form north (larger) to …

Journal of the Department of Agriculture, Western Australia, Series 4
ALTHOUGH the flora of Western Australia strongly attracted early botanists and collectors, it was virtually neglected by settlers faced with a century or more of hard pioneering.
Only recently has enthusiasm for our remarkable flora developed within the State and, with the formation of sponsoring societies and the establishment of the Kings Park Botanic Gardens, native species have become popular in home and civic gardens.
