ABSTRACT
By now, the reader should realize that wetlands are critical components of landscape. In previous chapters (3-18), we presented an overview of basic elemental cycles and their role in regulating larger wetland functions including water quality, production of greenhouse gases, carbon sequestration, and long-term burial of various elements into soil organic and mineral matter. Despite this discussion and better understanding of biogeochemical cycles, the roles of many of these processes in global elemental cycles are not well understood. In this chapter, we brie y review some of the recent advances in wetland biogeochemistry and attempt to direct readers to some promising areas for future research.
