Doctoral Dissertations. 1105. https://scholars.unh.edu/dissertation/1105 This Dissertation is brought to you for free and open access by the Student Scholarship at University of New Hampshire Scholars' Repository. It has been accepted for inclusion in Doctoral Dissertations by an authorized administrator of University of New Hampshire Scholars' Repository. For more information, please contact [email protected]. INFORMATION TO USERS This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You w ill find a good image o f the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation. Silver prints of "photographs" may be ordered at additional charge by writing the Order Department, giving the catalog number, title, author and specific pages you wish reproduced. 5. PLEASE NOTE: Some pages may have indistinct print. Filmed as received.

Sawyer for their guidance and assistance. Special thanks are extended to Dr. A. B, Hodgdon for his enthusiasm and support in helping with, this project as chairman of the committee before his unfortunate accident and to Dr.. A. L. Bogle for taking over as chairman at such a difficult time. I am grateful to Dr. E. G. Ogden for serving on my committee and for his help in the field and advice in preparing the manusoript. Mr. Owen Durgln, Associate Professor of Besouroe Economies, University of New Hampshire, provided Invaluable assistance in the statistical portion of the project. His time and effort are greatly appreciated. Dr. Alan Baker, Department of Botany and Plant Pathology, University of New Hampshire, provided much valuable advice on water chemistry and the preparation of graphs and tables. His critical review of the text was extremely helpful. Thanks are extended to Dr. LeBaron C. Colt, Jr., Professor of Biology at Boston State College and Dr. Robert R. Haynes, Assistant Professor of Biology, Louisiana State University at Shreveport, for their help in reviewing portions of the thesis. Dr. Rita N. McCauley, Biology Department Chairman, Boston State College, also gave much i tine in reviewing the text and supplying me with some of the chemicals and equipment utilized in.the project. My wife, Marion, deserves many thanks for all her encouragement over these many years of study and research. She actively participated in the preparation of this manuscript, particularly in the typing of all phases of it. To her, I owe special thanks. 11 TABLE OP CONTENTS LIST OP TABLES ............................... v LIST OP FIGURES........................ lx ABSTRACT ....................................... xii INTRODUCTION .................
