In total, 70 samples from everolimus ten sampling sites yielded 2798 individuals belonging to 28 different taxa (Table 2). The most frequent taxonomic grouping at the order level was Isopoda and at the class taxonomic level, Malacostraca. The most common feeding type was deposit feeders. The ratio of the number of species to the number of higher taxa, guilds and mix categories per site is shown in Fig. 2. The ratio was maximal for guilds in site KM (2.3 ± 0.4) but the grand mean of the ratio for all sites was higher for data aggregated in class (1.5 ± 0.3). The ratio between the number of species and the number of classes was higher in the low and mid estuary, whereas the ratio tended to be higher for guilds in the upper estuary. Because the ratio of the number of species to the number of categories in the mix aggregation included each species twice, its value was below or equal to 1 for sites along the estuary (grand mean for all sites 0.7 ± 0.2).
