Abstract
Cluster analysis, reciprocal averaging and a biotic boundary technique were used to analyze the relationship between community composition and topographic depth within 4 grass-sedge marshes in west-central Florida. Abundances of species fluctuated seasonally and varied between marshes. Communities in deep areas of individual marshes differed markedly from each other and from those in shallow areas. Reciprocal averaging showed no floristic gradients in the shallow marshes, but strong floristic gradients were highly correlated with water regime in deep marshes. Biotic boundaries within the marshes corresponded with water levels. The biotic boundary technique clearly delineated communities within the marshes and reflected the importance of seasonal water level fluctuations for community composition.
