Fluorometric Assay Of Free And Bound Coumarin Rn Sweetclover, Francis A. Haskins, Herman J. Gorz

Department of Agronomy and Horticulture: Faculty Publications

Free and bound coumarin are extracted by autoclaving leaf tissue in water. Free coumarin is determined directly from an aliquot of the water extract diluted in alkali. Additional autoclaving of the extract in concentrated alkali is required for release of the coumarin from the bound form, permitting an assay for total coumarin. Bound coumarin values are then obtained by difference. Results of the assay as applied to four different phenotypes of sweetclover are given.

The Relation Of Spring Bird Distribution To A Vegetation Mosaic In Southeastern Washington, Paul A. Johnsgard, W. H. Rickard

Paul Johnsgard Collection

Climax vegetation is of particular interest for study since it is the oldest and most stable vegetation of a region and should be expected to have a distinctive complement of animals. The purpose of this investigation was to observe the predilection of birds for stands representing climax plant associations in a remnant of native grassland in southeastern Washington.

The grasslands of this region were rapidly converted from grazing use to wheat production beginning about 65 years ago (Daubenmire 1942) and as a result only a few scattered remnants of native vegetation remain today. Associated with changes in vegetation there have …

Gyrodactylus Eucaliae N. Sp. (Trematoda: Monogenea) From The Brook Stickleback, Eucalia Inconstans*, Glenn L. Hoffman, Francis M. Ikezaki

United States Fish and Wildlife Service: Publications

A new species of Gyrodactylus was observed on the skin, gills, and fins of the brook stickleback from the English Coulee, Grand Forks, North Dakota during the summers of 1953-1955. Host-specificity is usually striking in the monogenetic trematodes and since this parasite was not observed on any other species of fish from this body of water or the nearby Turtle River, it was studied in detail and is here described as a new species, G. eucaliae.

New Polychrome Methods In Microtechnique, Celestino Nera Macabales

University of the Pacific Theses and Dissertations

When the writer took an introductory course in Microtechnique in 1954-55, he was impressed by the inadequacy of some microtechnical procedures recommended in triple staining, and he felt disappointed and discouraged by the consistently inferior results. He resolved to attempt modifications or to develop a new technique which could be relied upon to achieve anticipated results. This is a report on two years of efforts to develop a simple dependable technique in polychrome staining for histological studies. The writer feels that the results are of importance to students and teachers of biological science and to microtomists. The herein proposed technique …

The Value Of Including Chemistry Content In The Study Of High School Biology, Ramon Duane Buckley

Dissertations and Theses @ UNI

The purpose was to evaluate the effect of including some definite chemistry content in high school biology. This evaluation was made by comparing outcomes of instruction in two different groups of a high school biology course. The two groups were equated in terms of the intelligence quotients, the sex, and the previous achievement in biology of the class members. The comparative gains in factual knowledge were measured by means of an evaluation test. The comparative gains in appreciations and interests in biology were measured with a questionnaire.

Studies On The Trematode Larva Neascus, Thomas Reyes

University of the Pacific Theses and Dissertations

During the spring semesters of 1955 and 1956, while the writer was under the supervision of Dr. A. E. Noble, a preliminary survey was initiated on parasites in local fishes, amphibians, and reptiles occurring in the vicinity of Stockton, California. The collection of specimens in this survey included sixteen green sunfish, Lepomis cyanella, and two bluegills, L. macrochirus. Larval trematodes recovered from the heart and liver of these specimens belonged to the family Diplostomatidae Poirier (1886) which is characterized by a conspicuous constriction separating the fore and hind-bodies. The leaf-like forebody with the lateral borders converging ventrally to form a …

The Rabbit : An Illustrated Anatomical Guide, Edwin Chin Jr.

University of the Pacific Theses and Dissertations

This study on the anatomy of the rabbit was based on dissected material from the biological laboratories of the College of the Pacific. Because of existing errors in many of the present references to rabbit anatomy, the guide was prepared to meet the expressed need for a concise, illustrated outline of basic anatomy of the rabbit which might be used by students in an introductory course in mammalian or human anatomy. Since it is assumed that the guide would be supplemented by a dissection manual, syllabus, or textbook, textural material of such an outline is presented here in outline form.

Range Liverstock Nutrition And Its Importance In The Intermountain Region, C. Wayne Cook

Faculty Honor Lectures

It has been estimated that about 728 million acres or about 76 percent of the entire land area in the West is used for grazing (Stoddard and Smith 1956). In Utah about 93 percent of the land area or 48,900,000 acres is considered range land (Reuss and Blanch 1951). Although some of this range land is forested, a large area of it can be used only for grazing. Therefore, range livestock production is an important segment of western agriculture.

Before 19'00 most of the animals in the West grazed on the range all year. However, irrigation crop production has expanded …

You Can Get More Eggs, Boyd Bonzer, Lloyd Shinnick

SDSU Extension Circulars

One of the most common causes of lost profits and failure in poultry keeping is the lack of planning and foresight. A good poultryman is alert and wide awake; he is a person who spends a lot of time with small details-one who can watch his birds and sense when they start to get sick or go out of condition. He is a person who plans ahead and is prepared for the different phases of poultry management as the birds grow and mature.
