Papers from a recent symposium study the role of phosphorus in ecological health and metabolism of upland and wetland/aquatic environments. While focus is on Florida's ecosystems, results are discussed in the context of global issues. Looks at all levels of biological organization, from the cellular level to entire ecological communities, and presents the collective case work of a variety of state, federal, and private agencies. Covers physical, biological, chemical, and geological aspects of phosphorous behavior, and explains how phosphorous effects an entire ecosystem. Annotation c.
