All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Zooplankton of the littoral and limnetic zones of Bear Lake, Idaho-Utah, were collected over a 17-month period. Twenty-three species of zooplankton were recorded, as well as nine other species represented by both flora and fauna. At the time of sampling 17 physical and chemical parameters were also measured. Methods of analysis for the plankton and the environment are described and discussed.

The objectives of this project were fourfold:

1. To establish a record of the current zooplankton population before changes due to the increase of organic nutrients occur.
2. To compile a qualitative and quantitative standard against which future populations can be …

Factors In The Development And Restoration Of Waterfowl Habitat At Ogden Bay Refuge Weber County, Utah, Noland F. Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Millions of acres of marshland have been destroyed by the industrial and agricultural development of this continent. Drainage, water diversion, land leveling, and some other factors which destroyed waterfowl habitat were in most instances essential steps in man's progress; but water pollution, unwise drainage, and other soil and water abuses were tragic and unessential steps in our history of land exploitation that have destroyed vast acreages of habitat. The future of waterfowl on this continent hinges upon the success of restoration or new marsh development to replace this destroyed habitat.
