An Ecotypic Differentiation Of Human And Bovine Fecal Streptococci, With Application To Human Pollution In The Yakima River, Harlen Harvey Johnson
An Ecotypic Differentiation Of Human And Bovine Fecal Streptococci, With Application To Human Pollution In The Yakima River, Harlen Harvey Johnson
All Master's Theses
It was the purpose of this study to report on the development of a technique for distinguishing human fecal streptococci from bovine fecal streptococci, and to make application of this technique in describing some of the sources of pollution in the Yakima River as contributed by the Wilson Creek drainage system, in the Ellensburg area of Washington.
The Development Of The Embryo Sac In Ranunculus Glaberrimus Hook, Chung-Ping Chin
The Development Of The Embryo Sac In Ranunculus Glaberrimus Hook, Chung-Ping Chin
All Master's Theses
A comparative study of embryological and morphological characters of the ovule in the family Ranunculaceae indicates that considerable variation exists within this family.
The Effect Of Follicle-Stimulating Hormone And Testosterone Propionate On The Reproduction Of The Bull Snakes, Pituophis Melanoleucus Catenifer And Pituophis Melanoleucus Affinis; Accompanied With Analysis Of Changes In Blood Protein Constituents Following Stimulation, Jack Bradford
All Master's Theses
The bull snake, Pituophis melanoleucus, was chosen for this experimentation for several reasons; (1) it is relatively abundant in Central Washington (2) it is a large snake, well able to withstand the effects of the frequent blood samplings which were necessary in this experimentation ... (3) the bull snake is an oviparous snake and ova development is rapid and after dissection, obvious.
Geographic Variation In Dicamptodon Ensatus (Eschscholtz) With Notes On Life History And Zoogeography, Ronald A. Nussbaum
Geographic Variation In Dicamptodon Ensatus (Eschscholtz) With Notes On Life History And Zoogeography, Ronald A. Nussbaum
All Master's Theses
The purpose of this paper is to present information concerning geographic variation between three northern populations of Dicamptodon, and to add to the meager store of information concerning the life history and biology of the species.
Niche Differentiating Mechanisms In Two Sympatric Species Of Swallows, David Thomas Moody
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.
