This thesis merges the fields of Ecology and Anthropology by applying Habitat Suitability Modeling to the relationship between people and plants in the Pacific Northwest. In it, I create and optimize two Maxent habitat suitability models for camas (Camassia spp.) in Oregon. The first model describes the physical environment of...
The microbial loop plays a crucial role in remineralization of organic matter and fuels recycled production in the aquatic environment. The capability of microbes to utilize particular compounds can be examined through their ectoenzyme (found outside the cell) activities using fluorogenic substrate analogs. These catalysts hydrolyze polymers otherwise too large...
The objective of this research project was to evaluate the toxicity of
local pyrrolizidine alkaloid containing plants and to examine the influence
of dietary protein, with particular reference to the amino acid cysteine,
upon this toxicity.
Senecio vulgaris (common groundsel) was shown to be more toxic than
Senecio jacobaea (tansy...
Ten experiments were conducted to determine the vitamin requirements
of coturnix quail (Coturnix coturnix japonica) to 2 weeks
of age using a glucose monohydrate-isolated soybean protein diet.
A preliminary study consisting of 2 separate experiments was
conducted to determine those vitamins essential to the growing
coturnix. This study revealed that...

Deterioration of the flavor of sterilized concentrated milk (SCM)
is recognized as the principal limiting factor to commercial acceptance
of this product. Although a number of volatile compounds have
been identified in SCM, quantitative information on these compounds
is lacking. It is therefore difficult to ascertain the significance of
these...
Two experiments were conducted utilizing crossbred gilts to evaluate follicle characteristics at puberty and to determine the effect of exogenous estradio1-17β on embryonic mortality in the mature cycling gilt. Experiment 1 was conducted to compare preovulatory follicle numbers and sizes and follicular fluid concentrations of progesterone, estradio1-17β, plasminogen activator and...
The crawfish enterprise of South Louisiana is shown to haveexpanded as much as 18-fold since the 1950's. It is estimated(1973) that there are about 44,000 acres of managed crawfish ponds.Of the 334 ponds identified and mapped in the thesis, 231 are classedas open ponds, 45 as rice field ponds, and...
