         in a Carex meadow. Oecologia (Berl.) 28:233-246.

Principal components analysis of interrelations between tissue elements indicated a clear distinction between N, P, K, Cu, Mn, and Zn levels and ash, Ca, Mg, Na, and Fe levels on the first component. This difference related closely to water depth and fire frequency. Analysis of sedges, narrowleaf cattail, and the litter of this southern Quebec wetland suggested the loss of N, P, K, Cu, Mn, and Zn by volatilization, runoff, or leaching as shown by the coincidence of burning with water depth and the period of maximum snowmelt and runoff.
