Diversity Values |

Even though the correlation showed no significant relationship between species richness and the two predictor variables, we decided to plot and run the regression to visualize the relationship (or lack thereof). Figure 5 shows the regression line, function, R², and p-value for richness and island size, while Figure 6 shows these values for richness and distance to mainland. The low R² values suggest that the model does not explain very much of the response variable.
