Nematode univariate descriptors were the number of genera (richness; S), density (inds. 10 cm-2; N) and Shannon-Wiener diversity index (log2; H'). As functional attributes of the assemblages across the studied lagoons, we analysed the nematode feeding types , and the index of trophic diversity (1-ITD)  based on the proportion of each feeding type. Because the study encompasses both marine/estuarine and freshwater nematodes we used five feeding types: selective deposit feeders (1A), nonselective deposit feeders (1B), epigrowth feeders (2A), predators/omnivores (2B) and vascular plant feeders (3).
