Net primary production of the dominant bryophytes in a Sphagnum-dominated wetland in West Virginia.
Measurements of annual net primary production of Sphagnum magellanicum Brid., Sphagnum recurvum P.-Beauv., and Polytrichum commune Hedw. were 5.4, 6.1, and 7.9 g dry mass dm -2 , respectively, at Big Run Bog-a wetland in the unglaciated Appalachian Plateau of West Virginia. Production values for these three species were greater than other reported values in the literature. A general increase in annual production of Sphagnum spp. with decreasing latitude was documented. This trend is contrary to the progressive declines in the depths and sizes of inland peat deposits with decreasing latitude, suggesting that annual production is less important than annual decomposition in determining peat accumulation.
