Yearly metazoan macrofauna regressi<strong>on</strong> model (y = POC(a)+NOI(c)+ int.) used to estimate<br />
density-based community parameters TA D (dots), and PC D (circles) and RAD D similarity<br />
(crosses).<br />
Model fits evaluated using the F-test:<br />
TA D , n7, r 2 0.90, P = 0.011<br />
PC D , n7, r 2 0.80, P = 0.038<br />
RAD D , n7, r 2 0.85, P = 0.024<br />
