Data from a study of habitat configuration, specifically, does density of invertebrate epifauna on seaweed vary across sites with different levels of isolation from each other.

Usage

data(seaweed)

Format

A dataframe containing:

Size

A character vector describing size of experimental plots as "SMALL" or "LARGE"

Dist

Distance of isolation -- 0, 2 or 10 metres from other algal beds

Time

Sampling time - either 5 or 10 weeks from the start of the experiment.

Rep

The replicate number (1 to 5).

Wmass

Wet mass of the algal bed for that plot.

Total

Total invertebrate density in the plot, calculated as nuber of individuals divided by Wmass.

Other variables in the dataset give invertebrate counts separately for different taxa.
