Title	Occurrence and Distribution of Invertebrates in Lower Logan River
Description	M.S. thesis by Nancy A. Erman submitted in partial fulfillment of the requirements for the degree of Master of Science in Aquatic Ecology, Utah State University, 1968. Tyewritten, 72 one-sided pages. Includes tables and charts. Also includes Erman's vita.
Abstract	A study of bottom invertebrates on the lower Logan River, Logan, Utah was conducted from June 1966 to July 1967. One objective was to evaluate on a qualitative and quantitative basis the invertebrate populations above and below a sewage entry in the river. Another objective was to study the year round fluctuations in the invertebrate population. The greatest variety of invertebrates was found in the summer. Chironomidae and Baetis were the only two groups found in abundance over the entire year. Populations were reduced during autumn when water levels rose, and they declined even more sharply during the spring flood. At the station below the sewage entry a wide variety of Chironomidae genera were present and Oligochaeta numbers were low.
