PERMANOVA for the spatiotemporal effects of the Maule earthquake on intertidal sandy-shore assemblages.

The analyses were conducted on a Euclidean distance matrix for species richness and total abundance, and on a Bray-Curtis resemblance matrix of species abundances for community structure. The analysis was performed using Time (four sampling times: February 2010, March 2010, September 2010, and March 2011) and Area (two areas: Rupture and Control) as fixed factors, and Site (three sites located within each area) as random factor nested in Area. CV% = Components of variation.
