Results of simple linear regression analyses (applied to raw data) examining the relationship between <i>Desmarestia viridis</i> cover and urchin (<i>Strongylocentrotus droebachiensis</i>) density (x, urchins m⁻²) at 2, 3, 4, and 8 m depths at each of the two study sites, Bread and Chees

Each regression is based on 12 data points. Each point is the mean D. viridis cover and corresponding mean urchin density calculated from the 10 frames of each pair of transects for a given site, depth, and date.
