Ecological Evaluation in R - eeiR

A biotic index for the environmental quality assessment of marine macroalgae assemblages in coastal and transitional waters. The concept of EEI is based on the obvious and universal pattern that anthropogenic disturbance, eg, eutrophication caused by pollution, changes the pristine ecosystem, where climax species are dominant, to a degraded state, where opportunistic species are dominant".
