Title:Plankton Studies IV. The Plankton of the Illinois River, 1894-1899, with Introductory Notes Upon the Hydrography of the Illinois River and Its Basin. Part I. Quantitative Investigations and General Results
Author(s):Kofoid, C.A.
Illinois River
Abstract:When the work of the Illinois Biological Station was begun in lS94r. it seemed to the Director desiralile to determine as far as possible the normal routine of aquatic life as a necessary basis for the detection of problems for investigation and experiment, and as an indispensable background for their adequate solution. Such an investigation demands not only the discovery and specific determination of the biological population, Init involves also the study of life histories, seasonal changes, and mutual dependencies of the assembled organisms by quantitative and statistical methods, together with a study of the environment and an analysis of its factors. The plankton presented itself as the most available and concrete assemblage of organisms to which this method of study could be applied, and it afforded, moreover, a prolilem not only of prime scientific interest, but also of some important practical relation to fish culture. A presentation of the most general results of this investigation of the free microscopic fauna and flora, or plankton, of this typical stream of the Mississippi Valley is the object of the present paper.
