Food Habits Of Dicamptodon Ensatus And Associated Fish Species Of Maratta Creek, Washington, Authur L. Antonelli Aug 1969

Food Habits Of Dicamptodon Ensatus And Associated Fish Species Of Maratta Creek, Washington, Authur L. Antonelli

All Master's Theses

Three cold-blooded vertebrates, Dicamptodon ensatus, Cottus tenuis, and Salmo gairdneri were investigated as to food habits for a period of one year. The existence of competition between these animals for food was determined by means of stomach analysis. The results were compared relative to each vertebrate and the bottom fauna procurred from the stream. It was shown that the food habits of D. ensatus and S. gairdneri were diverse enough to warrant partial exclusion on the basis of food. C. tenuis demonstrated selectivity and was shown to be under competitive stress from the other two species.


The Effects Of Herbicides On Three Soil Inhabiting Blue Green Algal Species, Lee C. Darlington Aug 1969

The Effects Of Herbicides On Three Soil Inhabiting Blue Green Algal Species, Lee C. Darlington

All Master's Theses

The object of this study was to examine the effects of varying concentrations of 2, 4-D, Dalapon, and Tordon on the growth of several nitrogen-fixing blue-green algal species obtained from soil samples and grown under culture conditions in the laboratory.


Breeding Biology Of Cassin’S Finch, Carpodacus Cassinii, F. John Erickson Jr. Jun 1969

Breeding Biology Of Cassin’S Finch, Carpodacus Cassinii, F. John Erickson Jr.

All Master's Theses

The present study was undertaken in an effort to increase our understanding of this species' life history, with special reference to the functional significance of delayed plumage development in males. Field studies were conducted throughout the breeding season, and efforts were made to determine whether or not sub-adult males were successful in acquiring mates. In conjunction with consideration of the function of delayed plumage development in males of this species, a general review of this phenomenon has been undertaken in the order Passeriformes.


Purification And Properties Of Triosephosphate Isomerase From Selected Chlorophyta, John C. Meeks Aug 1967

Purification And Properties Of Triosephosphate Isomerase From Selected Chlorophyta, John C. Meeks

All Master's Theses

It is the purpose of this study to purify and investigate some of the properties of triosephosphate isomerase from two unicellular green algae 1 Ankistrodesmus Braunii and Scenedesmus acuminatus, and one filamentous green alga, Chara sp.


Evaluation Of The Short Sternum As Diagnostic Evidence For Trisomy-E, Frank George Deeter Jul 1967

Evaluation Of The Short Sternum As Diagnostic Evidence For Trisomy-E, Frank George Deeter

All Master's Theses

This study has demonstrated that a reliable technique for determining short sternums has been developed. Evidence for its reliability is given by two distinct and highly significant correlations.
