Niche Differentiating Mechanisms In Two Sympatric Species Of Swallows, David Thomas Moody

All Master's Theses

The present study considers certain aspects of the ecologies of cliff swallows (Petrochelidon pyrrhonota) and bam swallows (Hirundo rustica) in an area of overlap, where both species are found nesting together and foraging over the same fields. Careful attention was given to foraging flight patterns, foraging elevations, and food consumed by each species in an effort to determine whether or not there is any evidence of competition for food resources. Aggressive interactions between the species were recorded, and the general timing of their nesting cycles was noted.

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 …

Bulletin No. 379 - Biology And Control Of The Peach Twig Borer (Anarsia Lineatella Zeller) In Utah, Charles J. Sorenson, Farrell H. Gunnell

UAES Bulletins

The peach twig borer, Anarsia lineatella Zeller, sometimes called the peach worm, annually damages peach, apricot, nectarine, prune, and plum orchards in Utah. Many buds and twig terminals are destroyed each spring by the overwintered generation of partially grown larvae. These emerge from their winter quarters almost as soon as host trees begin their spring growth. From the time the fruit becomes about half grown until it is harvested, later generations of twig-borer larvae feed on it causing irregular, gummy cavities which make it unfit for market.

In order to work out a control program for any insect, its life …

The Biology And Seasonal Distribution Of Eucalliphora Lilaea (Walker) In Cache County, Utah, Robert P. Olson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The association of: flies with man has been recorded through many centuries. In nearly all of these records the association is one of discord rather than harmony. In the Book of Exodus, 8:24, in the King James version of the Old Testament, we can read, "...and there came grievous swarms of flies into the house of Pharaoh, and into his servants' houses; and in all the land of Egypt the land was corrupted by reason of the swarms of flies." Centuries later the "grievous swarms of flies" 'were associated with a particular disease by Mercurialis. In 1577 he expressed the …

Biology Of The Boxelder Bug In Cache Valley, Arab Bakir Al-Tikrity

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The boxelder bug, Leptocoria trivittatue (say), is a hanipterous insect belonging to the family corisidae. Although it rarely is a pest of agricultural crops, its habit of invading homes and other buildings for hibernation and to warm itself has made it an annoying household pest. It has proven to be a difficult insect to control. Only a few of the contact insecticides, useful in control of related insect pests, have given satisfactory control of the Boxelder Bug. Because it has not been considered a critical problem, it has not received detailed attention from the scientific investigators. Its close association with …

A Curriculum Study Of The Biological Science Courses In The Secondary Schools And College Of Utah During 1947-48, Merrill H. Gunnell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

At the present time there is a feeling among biologists in Utah that there should be improvement in biological science courses and course sequence to better fill the needs of the non technical student. There are many students filling group requirements with an accumulation of courses which may not provide them with the more important fundamental concepts and principles in biology. Information concerning these courses in high schools and colleges in necessary to provide a basis for curriculum revision in the field. Such information should be useful in evaluating the present system and suggesting modifications. Because of the need for …

Organization And Polarity Of Protoplasm, John P. Munson

All Faculty Scholarship for the College of the Sciences

In higher forms of life, we usually concede the presence of an organ specialized for the performance of a function. In these higher forms coordination of organs, which entails a regular sequence in their functions, is readily made out; and it seems a mere platitude to say, of these, that organization determines the functions of the organism. To what extent can functions exist in the absence of organization; does the one precede the other; or have function and organization developed simultaneously, out of matter devoid of both structure and function? In my studies on the cell, I have kept these …

Embryology And Evolution, Malo Marius Amunson

Manuscript Thesis Collection

The proofs of evolution must be sought in the entire field of science. Direct proof is found in the study of Morphology, whose bases are comparative anatomy; embryology; in the study of paleontology, of geology, of geographical distribution, in the study of nature and experiments of today. In this vast field of direct proofs of evolution it is our purpose to present some of the evidences of evolution as furnished by one of these, namely, Comparative Embryology.
