Early Records Of Some Mammals From Nebraska, J. Knox Jones Jr.

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

Ten species of Recent mammals that formerly occurred in Nebraska have been extirpated there by European man. Surprisingly few specimens of the species concerned are preserved in museum collections. Perusal of a representative segment of the historical literature pertaining to Nebraska has revealed records of occurrence of most of the extirpated species that provide a basis for estimating the former distribution of each in the State.

Growth Study Of Young Gizzard Shad, George Pahl, Gordon Willfahrt

Journal of the Minnesota Academy of Science

This investigation was part of a general study aimed at shedding light upon the role of the gizzard shad (Dorosoma cepedianum) as a forage fish of certain game fish species. Recent changes in the populations of such game fish species as the walleye ( Stizastedion vitreum), northern pike ( Esox lucius) , and largemouth bass (Micropterus salmoides) in the upper Mississippi River suggest that the gizzard shad population might have an important bearing on the present situation. The purpose of this investigation was to study the growth rates of the gizzard shad in the Upper Mississippi River during their first …

Farming Without Fallow, H M. Fisher

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

UNDER the more intensive cropping rotations common in the early development of the cereal areas of Western Australia bare fallowing was a basic technique in cereal production.

By ploughing the land in July or August and keeping it bare of vegetation for nine or ten months, either by grazing or cultivation, a substantial beneficial effect on the subsequent crop could be expected.

Shellfish Resources Of Washington, Robert Grant Levens

Graduate Student Research Papers

This paper will explore the salt water shellfish resources of Washington State. Particular emphasis will be placed upon the Pacific and Olympia Oysters, the Dungeness Crab, the research being done at Quilcene, and the lesser varieties of shellfish, including shrimp and the hardshell species of clams. The latter includes the littleneck, butter, Manila, and geoduc clams. A major emphasis will be the commercial importance of the shellfish, but the sportsman and the expanding role of Washington as a summer recreation area will not be overlooked.

Application Of Knowledge Of Medications By Senior Students In A Selected School Of Nursing, Patricia H. Okimi

Loma Linda University Electronic Theses, Dissertations & Projects

The problem arose from the need to study the present method of pharmacology instruction in a selected school of nursing. "How much knowledge of medications do selected senior students have, and how do they apply their knowledge in the administration of medications?"

For this study, the normative survey approach was used as the method of research. Eleven senior students of nursing engaged in the administration of medications, as team leaders, were observed and questioned on two different occasions during one quarter of their school year. The tool of research used to collect data was an observation code sheet developed for …

The Effects Of Certain Environmental And Biological Factors On Rally Calling In The Chukar Partridge, H. Warrington Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Naturalists for many years have known that birds sing most at dawn and at dusk, but to which of many physical variables they are responding has not been completely determined. This problem has taken on importance in the field of wildlife management because calling rate has been used as an index of abundance for numerous game birds, namely the Pheasant, Phasianus colchicus (Kimball, 1949); the Mourning Dove, Zenaidura macroura (McClure, 1939); the Bobwhite Quail, Colinus virginianus (Bennitt, 1951; Rosene, 1957): and the Woodcock, Philohela minor (Pitelka, 1943).

Bluebush Seed : Cleaning, Drying And Storing, C V. Malcolm

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

BLUEBUSH (Kochia brevifolia) is a perennial plant which occurs naturally in Western Australia.

In the past it has attracted little attention, but in recent years it has created interest as a highly nutritious and salt tolerant plant well adapted to certain salt affected soils in the wheatbelt.

A previous article (Bulletin No. 2630) by Smith and Malcolm drew attention to its use. One of the problems in establishing bluebush is to obtain seed supplies.
