Goodness of fit of the neutral model to relative abundance distributions in local communities with differences in species' per capita immigration probability.

<p>Parameter values: (a) <i>m</i> = 0.01, σ = 4; (b) <i>m</i> = 0.1, σ = 4; (c) <i>m</i> = 0.3, σ = 4. Each point represents the percentage value by comparing the LV and LV<i>_i</i> (<i>i</i> = 1, …, 100) for each replicate simulation of the same parameter set.
