Effects of nutrients and hydroperiod on Typha, Cladium, and Eleocharis: Implications for everglades restoration
S. Newman, James B. Grace, J. W. Koebel
1996, Ecological Applications (6) 774-783
The recent expansion of Typha domingensis (Typha) into areas of the Everglades previously dominated by Cladium jamaicense (Cladium) communities has led to competing hypotheses about the importance of nutrient concentration vs. hydroperiod in controlling the distribution of these species. In this study, experimental mixtures of Typha domingensis, Cladium jamaicense, and...
