Plant Response Parameters To General Patton's Armored Maneuvers In The Eastern Mojave Desert Of California, Randall J. Iwasiuk Aug 1979

Plant Response Parameters To General Patton's Armored Maneuvers In The Eastern Mojave Desert Of California, Randall J. Iwasiuk

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study, which was undertaken from September, 1977 through June, 1978 was to survey the response of perennial vegetation to General Patton's World War II armored maneuvers. This information will be used to help construct a basis for predicting recovery rates on the effects of off-road vehicle impacts in the California Desert Conservation Area (CDCA). These impacts were assessed in three usage categories: tank tracks in the maneuvers areas; roadways, which were used primarily by jeeps and trucks; and tent areas, cleared areas in which tents and other semi-permanent structures were erected. The data generated from these …

Growth Of Phytophthora Infestans Race 1.2.4 And Synthesis Of Steroid Glycoalkaloids By The Fungus In Synthetic Media, Melanie R. Maas May 1979

Growth Of Phytophthora Infestans Race 1.2.4 And Synthesis Of Steroid Glycoalkaloids By The Fungus In Synthetic Media, Melanie R. Maas

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A chemically defined synthetic medium was developed in which Phytophthora infestans (Mont.) de Bary race 1.2.4 grew extensively. This medium consisted of: 90.0 grams maltose, 20.0 grams DL-alanine, 20.0 grams L-proline, 1.0 gram KNO3, 0.5 gram KH2PO4, 0.25 gram MgSO4. 7H2O, 1.0 milligram thiamin per liter of distilled water. The average level of growth in this medium was 0.5864 gram dry weight mycelium per 50 milliliters medium.

The glycoalkaloids, solanidine and solanine, were synthesized by Phytophthora infestans in the above medium with 62.5 percent of the samples positive and an overall …

Some Physical And Biological Factors Affecting Red-Tailed Hawk Productivity, Stewart Wayne Janes Jan 1979

Some Physical And Biological Factors Affecting Red-Tailed Hawk Productivity, Stewart Wayne Janes

Dissertations and Theses

Various physical and biological factors affecting annual productivity in a Red-tailed Hawk population in north-central Oregon were investigated. The percentage of the population successfully fledging one or more young was the most important factor in determining the number of young fledged per pair in a given year. Neither clutch size nor the number of young fledged per successful nest varied significantly. Percent pair success was correlated with several January weather variables. A cold and dry January is positively correlated with Red-tailed Hawk productivity. This is apparently related to the onset of rapid vegetative growth and this in turn is positively …
