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 The Utah Sculpin Cottus Bairdi Semiscaber In Logan River, Utah, William Merle Zarbock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study of the Utah sculpin Cottus bairdi semiscaber, or Rocky Mountain bullhead as it is known locally on Logan River, Utah, is primarily one of determining its relation to game fish. Field work for this study began in 1949 and continued to March of 1951. Numbers of the Utah sculpin on Logan River have been estimated to be as high as 150 per tenth mile of stream. The larger populations are in the area of the third impoundment on Logan River and downstream.

Studies On The Ecological Distribution Of The Genus Tegula At Bodega Bay, California, Allen Emmert Breed

University of the Pacific Theses and Dissertations

This paper is primarily a study of the factors contributing to the distribution of Tegula funebralis and Tegula brunnea in the vicinity of Bodega Bay, California. The two species seldom appear extensively together in the same zone. Tegula brunnea is found on the exposed outer coast of Tomales Point, but not in the immediate zone of Tegula funebralis. Tegula funebralis is found at some points north of Dillon Beach, but it is rarely in the presence of abundant Tegula brunnea. The writer hopes that his efforts may lay a basis for more ecological studies of this genera on the Pacific …

Notes On The Distribution Of Amphibia And Reptilia Of Ellis County, Kansas, Lawrence A. Brennan

Master's Theses or Doctor of Nursing Practice

Comparatively little has been done concerning the listing or recording of the Amphibia and Reptilia of Ellis County, Kansas. What records there are of the species are for the most part unpublished. Early papers dealing with Kansas herpetology are few in number. Little has been done in Ellis and the surrounding counties, so there seems to be a need for such an ecological study as has been carried out in this paper “Notes on the Distribution of Amphibia and Reptilia of Ellis County, Kansas . " The objectives kept in mind in preparing this report have been to attempt to …
