Effect of the increase in the copra price and fishing on the coral reef ecosystem.

<p>Ecosystem models and estimates of elasticities from a path analysis of the effect of fishing on the coral reef ecosystem, occurring primarily through changes in (a) total fish biomass and (b) biomass of herbivorous fish only. * p<0.1, **p<0.05, ***p<0.01+ Based on econometric results. The relative size and color (black: positive, gray: negative) represent the magnitude and sign of the effect.
