SUMMARY:

The Atlantic Forest stands out for the wide biodiversity of fauna and flora, however it has
been impacted by anthropic action with the introduction of exotic species, which can alter
the quality of the soil and litter, and consequently the dynamics of the invertebrate biota.
The bamboo and eucalyptus species are easily found in Urban Parks with Atlantic Forest
vegetation, such as the Parque do Horto de Maceió. Thus, the objective was to evaluate
which impacts the introduction of exotic species Bambusa vulgaris (bamboo) and
Eucalyptus sp. (eucalyptus) have affected invertebrate biodiversity and soil quality in an
Atlantic Forest fragment. The research is being carried out in Parque do Horto de Maceió
(IBAMA), in three areas: Atlantic Forest, Eucalyptus and Bamboo, with 10 points in each
environment. To quantify the rate and intensity of damage caused by invertebrate
herbivores on the leaves of B. vulgaris, Eucalyptus sp. and Paubrasilia echinata (Mata
Atlântica) leaves were randomly collected from 10 matrices. For the survey of aerial and
soil macrofauna, Provid traps were used. Soil+litter samples were collected to quantify
the mesofauna using metallic rings (diameter=4.8 cm and height=5 cm) at a depth of 0-5
cm and subjected to the Berlese-Tullgren extractor method. In order to evaluate the
accumulation of litter, an iron frame (0.5x0.5 m) was used randomly, and the material
was sorted, dried in an oven, weighed and the litter invertebrates were sampled. Soil
samples were collected to determine the physical and chemical parameters. Chemical
analysis of plant material and litter (Lignin, Cellulose and Hemicellulose, C, N, P, K and
Mg) is carried out. In addition to analysis of edaphoclimatic factors (Soil Water Content-
CAS, Soil Temperature-TS and Rainfall-PP). For invertebrates, abundance, richness,
Shannon diversity (H) and Pielou uniformity (e) were quantified. All data will be
submitted to statistical analysis. Preliminary results indicate that the abundance and
richness of the aerial macrofauna were homogeneous in the areas (Bamboo>Atlantic
Forest>Eucalyptus), attributed to the adaptation of invertebrates to exotic species, with
Coleoptera and Diptera being the most dominant by indices (H) and (e). The edaphic
macrofauna was more abundant in the Atlantic Forest, due to the absence of anthropic
interventions, allied to the composition of the diversified vegetation, whereas the richness
was greater in Bamboo, motivated by the CAS and regardless of the areas Coleoptera was
dominant, favored by the PP. The richness of groups captured in the litter stood out in the
Atlantic Forest, which has a wide vegetational diversity, in relation to areas with exotic
species, with dominance of Hymenoptera in the Atlantic Forest and Eucalyptus areas, and
Diplopoda in Bamboo, confirmed by (H ) and (e); Litter accumulation was concentrated
in the Eucalyptus>Atlantic Forest>Bamboo areas, attributed to the PP and CAS variables,
which influenced the invertebrates. And the greatest richness of the mesofauna occurred
in the Atlantic Forest due to the balance of the environment, greater complexity and
structural stability, and the abundance stood out in Bamboo, attributed to the percentage
of CAS, with Acarina standing out as dominant in the areas, according to the ecological
indices.
