Abstract
The purpose of the survey is primarily to identify the microscopical animal forms which are likely to be met with by the zoologist and ecologist in his investigation. If he is to make observations of value to others, he must be reasonably accurate in the name which he applies. It is hoped the present study will make easier the identification of forms which the ecologist may meet.
The following lists, naturally, are not complete. Perhaps future studies based on this one will more nearly approach the ideal in completeness an in accuracy. Determinations were made through use of keys and labeled specimens in collections at the Kansas State Teachers College, Pittsburg, Kansas.
This paper contains the results of studies made by the writer of the microscopical animal forms of a selected area of the Sac River, from September 1, 1931 to April 1, 1932, inclusive.
In 1931, the writer decided to collect and list as many species of microscopical animals forms found in a selected area, and to describe in as an accurate way as possible each form found.
Practically no surveys of fresh water biology have been made in Missouri, with the exception of a minor one at Bennett Springs. The Missouri University, the Game and Fish Department, the State Board of Health, and the five State Teachers Colleges had no record of such a survey.
The importance of microscopical forms to vertebrate and large invertebrate life in the streams is well recognized. The fish feed on Malacostraca, Decapoda, Entomostraca, and other small animal forms, which in turn feed on microscopical forms.
The restocking of streams with fish, the parasites of farm animals that water at running streams, and public sanitation show the need of a survey.
