<br />Authors were encouraged to relate their segment
<br />of river system to tributaries and to the river down-
<br />stream. The impacts of altered hydrologic, sedi-
<br />ment, and organic matter cycles were to be de-
<br />scribed, as well as such changes as the availability
<br />of woody debris in the river cross-section, loss of
<br />floodplain and side-arm connection, and changing
<br />water quality. The symposium was held at the
<br />122nd amlUal meeting of the American Fisheries
<br />Society on 13-15 September 1992 in Rapid City,
<br />South Dakota.
<br />The published proceedings includes papers cov-
<br />ering 19 different large river systems in the Missis-
<br />sippi River basin and broad perspectives on sedi-
<br />ment transport, riparian plant communities,
<br />altered hydrologic cycles, contaminants, threat-
<br />ened and endangered species, and communication.
<br />Several additional papers were prepared for oral
<br />presentation that were not included in the proceed-
<br />ings because of the busy schedules of the authors.
<br />The following is a listing of these oral presenta-
<br />tions.

<br />We must view preservation and restoration of
<br />various segments of the Mississippi River ecosys-
<br />tem for more profound reasons than for increasing
<br />the catch of commercial and sport fish species.
<br />This system is a natural resource heritage. On a
<br />long-term basis, restoration offers the only option
<br />capable of preserving a desirable quality of life.
<br />Schmulbach (1988) said it well: "although we at-
<br />tempt to escape the restrictions of the natural
<br />world, man can only live so long on capital. The
<br />planet's natural resources are limited, as is their
<br />capacity to endure and even if the human majority
<br />fails to appreciate the intrinsic value of many
<br />species, it is in the vested interest of humans that
<br />all species and ecosystems survive."
