Abstract

In the summer of 1932, an investigation of some biological, physical, and chemical conditions at the Bear River Migratory Waterfowl Refuge, Utah, was begun at the Utah State Agricultural College to determine some of the factors governing the biological productivity of brackish-water marshes. Unfortunately, lack of funds made it impossible to continue work beyond the first season.

In 1936, the Wild Life Experiment Station at the Utah State Agricultural College appropriated a fund for a cooperative project between the Station and the Department of Botany at the same institution. This project, planned to be continued by various graduate fellows over a period of several years, is an investigation of conditions existing at the Bear River Refuge and at some newer refuges of similar character.

It was believed that the micro-biota of the water at the Refuge is of importance in the study of general conditions, and consequently provisions were made to determine what organisms, exclusive of bacteria, compose the microscopic population of the waters at the Refuge, and what their seasonal and geographical distribution within the area is. This paper is a report on this particular phase of the investigation.

Acknowledgments are due to Dr. D.I. Rasmussen, who made the project possible by procuring the necessary financial support, to Professor Bassett Maguire, who directed the study, and to the personnel of the United States Biological Survey at the Bear River Refuge, who generously provided laboratory space, boats, and living quarters during periods of field activity.
