2] fixation, are considered to be the main sources of these elements for mosses in ombrogenous bogs and acidic fens (Malmer 1992).
Sphagnum mosses that typically occur in ombrogenous bogs and in nutrient-deficient tundras have much longer leaf longevity (8 yr) than other mosses occurring in more geogenous environments (3 yr; Chapin et al.
For instance, several studies have shown that both N and P mineralization rates and the inorganic pools of these elements increase from fens to bogs, which speaks against the notion of decreased plant nutrient availability from geogenous to ombrogenous wetlands (Verhoeven et al.
For instance, wet and moist nutrient-rich sites such as riparian areas are generally dominated by deciduous Salix shrubs, geogenous fens by sedges, and ombrogenous bogs by evergreen shrubs, rushes, and Sphagnum mosses (Chapin et al.
This is perhaps most clearly demonstrated by the peat accumulation by Sphagnum that, under certain hydrological and topographical conditions, may turn mineral-influenced fens into ombrogenous bogs (Sjors 1948, Damman 1986).
The accumulation of peat in ombrogenous bogs (Clymo 1984) and of organic matter in geogenous wetlands (Shaver et al.
