Richness and Diversity of the Edaphic Macrofauna in a Brazilian Seasonally Dry Tropical Forest | ...
The aim of this study was to see how seasonality affected the diversity and richness of the edaphic macrofauna in a Caatinga area in the Brazilian semiarid region during the dry and rainy seasons. During rainy and dry seasons, samples were collected in a sample grid with a total of 10 points spaced 30 metres apart. The total number of organisms (species abundance) was calculated according to diversity for quantitative assessment of macrofauna. For the rainy and dry cycles, the diversity of the soil macrofauna corresponds to the following order: Hymenoptera> Diptera> Aranaea> Orthoptera> Coleoptera, with a greater predominance of the order Hymenoptera. Seasonality was observed in relation to the richness and complexity of the region's macrofauna, with significant differences between rainy and dry periods.
