Stronger Tests of Mechanisms Underlying Geographic Gradients of Biodiversity: Insights from the Dimensionality of Biodiversity
Figure 5
Scatter plots indicating variation in combinations of slope and intercept for the relationship between empirical and simulated gradients in different measures of biodiversity generated from the MDE analysis.
Dots represent the combination of slope and intercept for each run. Large figures represent a subset of simulation runs that were close to the theoretical expectation of zero intercept and slope of unity. Inset represents relationship based on all 1,000 simulation runs. The two intersecting lines represent the theoretical expectation. If there is good fit between observed and expected values then the confidence envelope will overlap the point of zero intercept and slope of unity.
