ABSTRACT: Cedar Bog Nature Preserve, located near Urbana, OH, encompasses several wetland types including an alkaline fen. In this fen, groundwater emerges in quicksand-like discharge zones consisting of porous Ca/Mg carbonates mixed with organic detritus. This study evaluates seasonal changes in the heterotrophic sediment microbial communities, their response to nutrient amendment, and in the groundwater chemistry from a fen discharge zone at Cedar Bog. The hypothesis that the mic...
