Mathematical Analysis of Decision Problems in Ecology: by Abraham Charnes, Kingsley E. Haynes, Jared E. Hazleton,

By Abraham Charnes, Kingsley E. Haynes, Jared E. Hazleton, Michael J. Ryan (auth.), Dr. A. Charnes, Dr. W. R. Lynn (eds.)

The contents of this quantity contain choice, emendation and up-dating of papers offered on the NATO convention "Mathe­ matical research of selection difficulties in Ecology" in Istanbul, Turkey, July 9-13, 1973. It was once subsidized by means of the process Sciences department of NATO directed by way of Dr. B. Bayraktar with neighborhood organize­ ments administered by means of Dr. Ilhami Karayalcin, professor of the dept of commercial Engineering on the Technical college of Istanbul. It was once equipped by way of A. Charnes, collage professor around the collage of Texas procedure, and Walter R.Lynn, Di­ rector of the varsity of Civil and Environmental Engineering at Cornell Unjversity. the target of the convention used to be to compile a gaggle of prime researchers from the foremost sciences excited about eco­ logical difficulties and to give the present country of development in learn of a mathematical nature which would help in the solu­ tion of those difficulties. even supposing their shows usually are not herein recorded, the foremost­ notice handle of Dr. John A. Logan, president, Rose-Hulman Institute of know-how and the presentation of Dr. Michael J. L. Kirby, then Assistant vital Secretary to the most desirable of Nova Scotia, Canada, tremendously stimulated the dialogue of papers and their next emendations and revisions.

The issues contained during this sequence were gathered over a long time with the purpose of supplying scholars and lecturers with fabric, the quest for which might in a different way occupy a lot invaluable time. Hitherto this focused fabric has in basic terms been available to the very constrained public capable of learn Serbian*.

Example text

A focus for this type of analysis can be achieved by utilizing the ecosystem concept. Failures in environmental management often result because of a widespread lack of appreciation o£ the complexity of nature and the widespread acceptance of the naive assumption that somehow or other nature has the capacity to absorb all the types of manipulations we throw at her and still serve man in ways most desirable to him. The polluted condition of our air and water, and tragedy of Lake Erie, and the increasing burden of non-degradable pesticides on the world ecosystem are, in large part, the accumulated result of many small economic or political decisions made without due regard to all of the ecological factors involved.

In the cutover ecosystem, the increased loss of cations is correlated with the increased loss of nitrate anions. Consequept1y, if the intact vegetation inhibits the process of nitrification as workers in other regions have shown and removal of the vegetation promotes nitrification, the release of the process of nitrification from inbibition by the vegetation may account for major nutrient losses from the cutover ecosystem. Results of the particulate matter study also indicate a basic change in the pattern of losses.

For example, increases in the input of sodium and magnesium may result when our area is under the dominance of maritime air masses. Our data also indicate a steadily increasing trend of nitrogen input over the past six years. This may be a reflection of increasing air pollution. Our data show that concentrations of metallic cations in drainage water from our undisturbed forests are remarkably constant even though the discharge of stream water from our watersheds 23 ranges over four orders of magnitude, varying from summer trickles to spring torrents.
