Table 2 Output of the PERMANOVA analysis carried out to test for differences in total phytopigments, biopolymeric carbon, percentage of chlorophyll-a to biopolymeric carbon and to phytopigments, percentage of proteins to biopolymeric carbon, protein to carbohydrate ratio and biochemical composition of organic matter between undisturbed and disturbed mangrove areas (df = degrees of freedom; MS = mean square; Pseudo-F = F statistic; P(MC) = probability levels obtained from Monte Carlo asymptotic distributions).
From: Impact of mangrove forests degradation on biodiversity and ecosystem functioning
