3.2. Littoraria angulifera substrates (vegetation)

The trees on which specimens from Lot A were collected were all Rhizophora mangle L., the red mangrove.In M1 the trees were lower (p<0.01) and also less thick (p<0.05) in relation to M2, but there was homogeneity between the sample levels (L1 and L2) in each of the localities ( Table 1). The minimum height recorded in M1 was 3.1 m and the maximum was 6.4 m, and in M2, the heights varied from 3.1 to 12.26 m, with the medians being 4.6 and 6.5 m, respectively. Only in M1 was observed the marine grass Spartina alterniflora Loisel ( Poaceae ), with an average of approximately 20 cm in height, on which the animals of Lot B were collected. The grass was irregularly distributed among the trees of R. mangle .
