• Abstract:

  The epigeal fauna is considered an important ecological indicator acting in

  several and relevant processes in the soil, promoting the maintenance of environmental

  services. Therefore, this study seeks to characterize the diversity of the epigeal fauna

  through ecological indexes, in different vegetation coverages in the Botanical Garden

  of the Federal Rural University of Rio de Janeiro. Three areas were selected according

  to their layout in the landscape. Being Area 1 (A1) located in the highest part of the

  landscape characterized by the presence of forest cover and clayey texture in the

  superficial layer; Area 2 (A2) located in the middle part of the landscape is characterized

  by the predominance of Poaceae (grasses) and Area 3 (A3), located in the lower part,

  presents sandy soils on surface and with forest species. For the collection of the

  organisms the Pitfalls trap method was used, installing 5 traps per area in the Autumn

  and Spring seasons. There were 25 different taxonomic groups were recorded, being

  Blattaria, Chilopoda, Dermaptera, Isoptera, Psocoptera and Thysanoptera recorded

  only in the autumn and Oligochaeta and Symphypleona recorded only in Spring. The

  group Formicidae was the most representative independent of the area or season of the

  year. A higher similarity was observed between A1 and A3 when compared to A2. The

  diversity of organisms registered in different vegetation cover indicates the importance

  of the same for the maintenance and quality of the soil of the Botanical Garden.
