Population densities of Phormidium filaments varied considerably, both within and between fields. Spatial variation in density of Phormidium filaments (log10 [x + 1] g wet mass plants−1) across transects in an EGS field (A) and a horse control field (B). Each datum point represents the density for each of 10 points across the field transect. Medians are marked.
