A perfect correlation between cumulative area and cumulative number of species would result in a r-squared value of 1. Therefore, the higher the r-squared value, the better the fit of the data to the model of a power curve. Also, be sure to move the equation and r-squared value so they are not obscured by the line or by any points.

If a risk difference in the strength training group of 0.5 is considered detrimental (i.e., with probability 0.55 of rapid loss in the strength training group), then by using Fisher’s exact test, the study would have 82% power to detect this difference with 15 subjects per group. This is a one-sided test at alpha = 0.05.”
