Interpool distribution studies of 10 vernal pools on the Santa Rosa Plateau found area to be the best single predictor of species richness in each type of regression model evaluated. Area predicted most accurately in a mixed linear-curvilinear regression model (y = a + b log x). Area appeared to reflect ecologic diversity, because multiple linear regression models provided better predictions of species richness using combinations of physical characteristics which excluded area from the regression equation. In addition, species turnover was demonstrated in a single vernal pool that was evaluated.
Intrapool distribution was studied along a soil moisture/microtopographic gradient in a single vernal pool on Mesa de Colorado. Plant species were found to be both temporally and spatially segregated. Plant species abundances in individual sample plots are arranged in an approximate geometric series, with few species in each sample and dominance concentrated in only a few of these.
