Description
Area coverage of red algae (Mazzaella parksii) in two herbivore
treatments (herbivores) at two tide levels (height).
Format
A data frame with 64 observations on the following 3 variables.
- height
a factor with levels low and
mid
- herbivores
a factor with levels minus and
plus
- sqrt.area
a numeric vector
