Biogeochemistry research needs: observations from the ecosystem studies program of the National Science Foundation

This comment presents current and emerging areas of research which the U.S. National Science Foundation believes have special promise for advancing ecosystem science. These areas are: (1) major element cycle interactions; (2) trace element and organic compound controls on ecosystem dynamics; (3) the role of consumers on ecosystem dynamics; (4) ecosystem dynamics in contrasting environments; (5) landscape ecology; and (6) enhancement of theory and methodology. The Ecosystem Studies Program of the National Science Foundation has identified these as areas to be emphasized in its long range planning program (revised March, 1985). Biogeochemical studies are emphasized in many of these research priority areas.
