Abstract

The AA. examined how hydrology influenced water chemistry, vegetation, nutrient status, aboveground net primary production (ANPP) and litter decomposition rates in 2 mires on the South-Eastern Alps of Italy. They chose 2 pristine peatlands strongly differing from each other as regards both water chemistry and vegetation cover, with one of the 2 sites being prevalently covered by bog-like vegetation and the other by fen-like vegetation. Contrary to their expectations, ANPP did not differ significantly between the 2 mire sites while litter decomposition rates were significantly lower in the fen-dominated mire, presumably because of phosphorus (P) limitation of decomposers. This suggests that the development of ombrogenous mires in this region need not be due to increased accumulation of peat during succession from mineralwater-fed to rainwater-fed conditions
