A Preliminary Study Of The Distribution Of Fleas In Utah Known To Be Capable And Potential Vectors Of Plague, Dorald M. Allred
Theses and Dissertations
Plague outbreaks in the past have been disastrous where domestic rats and their fleas of certain species were common. Plague has been known to occur in most parts of the world (Robertson 1923), and has occurred as human epidemics for many centuries (Dubos 1948).
Ecology Of Passerine Birds Wintering At Utah Lake, Joseph R. Murphy
Ecology Of Passerine Birds Wintering At Utah Lake, Joseph R. Murphy
Theses and Dissertations
During the period of October to April of the winter of 1950-51, an ecological study was undertaken of a population or passerine birds wintering in a segment of the Utah Lake Shore. Available winter weather data indicated that although such factors as precipitation, temperature, and wind may often be severe, they are not critical enough to prevent a fairly large population of passerine birds from spending the winter months in the study locale. Five fairly distinct plant communities can be recognized in the area. There is evidence which indicates that certain passerine bird species are especially dependent on a particular …

An Ecological Study Of A Sphagnum Lake In The Subalpine Forest Of The Uinta Mountains Of Utah, Howard C. Stutz
Theses and Dissertations
A study was made of the ecology and floristics of a small bog lake referred to as Moss Lake, in the Grandaddy lakes region of the Uinta Mountains , Utah . Three consecutive summers, 1948, 1949, and 1950, were spent in collecting the data presented in this study. Throughout the study the following ecological measurements were made: 1. Water 2. Soil 3.

Alpine Plant Succession Near Mount Emmons, Uinta Mountains, Utah, Joseph R. Murdock
Alpine Plant Succession Near Mount Emmons, Uinta Mountains, Utah, Joseph R. Murdock
Theses and Dissertations
It was to provide some detailed information about the alpine flora , particularly as it relates to successional aspects , that the present study was undertaken . The environmental conditions of weather and soil , as they effect floral composition , are important factors in the plant succession or alpine communities . The investigation was designed to uncover such information about the alpine flora and environment necessary to establish the pattern of succession .
