Book excerpt: This volume is based on the proceedings of a conference held at Florida State University in April, 1978. This conference was supported by the Florida State University Graduate Research Council, the Department of Biological Science (F. S. U. ), and the Center for Professional Development and Public Service. Particular recogni tion should be made of the efforts of Dr. Anne Thistle in the organization of the conference and the completion of this book. Julia K. White and Sheila Marrero produced the typescript. The principal objective of the conference was to assemble a group of marine scientists from diverse disciplines to discuss the state of marine ecology with particular attention to new research directions based on previous studies. Emphasis was placed on the integration of different research approaches and on the application of established procedures to various environmental problems. An effort was made to eliminate traditional disciplinary boundaries which often hinder our understanding of marine systems. There was generally wide latitude for review and speculation concerning such topics as physico-chemical processes, productivity and trophic interactions, population distribution and community structure, and natural or anthropogenic disturbance phenomena. Throughout, the usual miniaturization of the scope of discussion was subordinate to a frank appraisal of the present status of marine research. Although many introductory ecological texts stress the so called ecosystem approach, individual marine research projects seldom encompass this broad course. There is, in fact, a real need for system-wide studies at both the theoretical and applied levels.

Book excerpt: A freshwater floodplain swamp ecosystem, creeping swamp, on the lower coastal plain of North Carolina was the site of intensive, coordinated studies of system structure and functioning focused on organic carbon and phosphorus. The swamp, usually flooded in winter and early spring by darkly-colored water low in conductivity, pH, and plant nutrients, supports a typical deciduous hardwood bottomland forest. The investigations emphasized field measurements of the major compartments and of the dominant fluxes between these compartments in the natural swamp for two years. In addition the fluxos of carbon and phosphorus into and out of the swamp ecosystem were detemined and material budgets were constructed. The abundances of iron and manganese in several physical and chemical forms in water and soils were also measured. Most of the organic C in the swamp ecosystem (22 kg.m-2) was present in living trees and saplings (63%), and almost all of the remainder occurred as swamp floor litter, logs, and soil organic matter (to 25 cm depth). Annual inputs to the swamp in 1977 amounted to 902 g C.m-2.yr-1 of which 21% was organic C in stream flows into the swamp and 77% was net primary productivity of trees, saplings, shrubs, and herbs. Internal cycling of organic carbon, amounting to 352 g C.m-2.yr-1, was comprised of litterfall (77%), macrolitter (17%), and throughfall and stemflow (6%). Organic C outputs from the swamp (541 g C.m-2.yr-1) were partly provided by stream flow (40%) but mostly by litter respiration when the swamp was not flooded 45%, by aquatic benthic respiration (8%), water column respiration (5%), and anaerobic respiration (2%). The swamp exported organic C (about 20 g C.m-2.yr-1), mostly as dissolved and colloidal humic materials. Most of the phosphorus in the swamp ecosystem (about 39 g P.m-2) was in the upper 25 cm of soil (86%), with the remainder mostly in aboveground vegetation. Annual P input to the ecosystem (1050-1290 mg P.m-2.yr-1) was carried predominantly by surface waters (94%), with bulk precipitation delivering the rest. Internal P cycling consisted for the most part in filterable reactive P uptake from the floodwaters, to algae and to the forest floor, and sedimentation; a substantial portion of this uptake supported the vegetation cycle from tree roots to canopy to litterfall and throughfall back to the swamp floor. Much of the particulate P in the floodwaters sedimented out on the swampfloor. The swamp floor also returned filterable unreactive P back to the water. There was marked retention of phosphorus by the swamp resulting in very low P concentrations in the water downstream. Iron and manganese exist in swamp waters and soils in a large variety of physical and chemical forms which change in concentration through the year. Largest amounts were associated with soil particles, next highest concentrations were in soil pore water, and lowest amounts were in the swamp floodwaters. Significant positive correlations existed between particulate P concentrations and unreactive particulate Fe concentrations in floodwaters.
