The rank order of species extinction in response to different disturbances in natural undisturbed marine coastal ecosystems.

A species extinction order was obtained in the case of each ecosystem by ranking the value of the slope of the 0 standardised relationship (for which values of F, p and r2 are presented) between abundance relative to controls and disturbance intensity in the case of salt marsh plants and duration in the remaining communities (see Figure S1). Salt marsh plants were treated with elevated quantities of fucoid algal mats, sessile invertebrate communities were exposed to hypoxia, and elevated wave exposure was simulated on macroalgal turfs. Rank ES is Rank Extinction Susceptibility where 1 is the most extinction susceptible species. Numbers in parenthesis represent the degrees of freedom of each regression estimate.
