dc.description.abstract | Edaphic ecosystems are the basis for the production of terrestrial biological resources and
their dynamics affect not only the natural environment but also society and their economic
activities. In Caatinga biome, the semi-arid climate associated with an inadequate soil
management has increased the degradation and loss of productive potential of the soil. In this
context, the study of soil fauna, including springtails, becomes an important indicator of soil
quality. This study aimed to evaluate the fauna of Collembola in an area of Caatinga of Rio
Grande do Norte State and the influence of biotic and abiotic factors, such as soil, vegetation
and climate characteristics, on the structure of the taxocenosis. The environmental variables
which were used were the following ones: granulometry (represented by the proportion of
sand), quantity of organic matter and soil pH, richness, density and aerial biomass of the
vegetal structure, and necromass. We used pitfall traps intending to collect specimens of the
epiedaphic fauna of Collembola in 30 points located on Cauaçu Farm, João Câmara, RN, in
July (rainy season) and November (dry season) 2011. We collected 5513 individuals of 15
species distributed in 13 genera and 9 families of Collembola. Five of the recorded species are
new to science, confirming the expected high degree of endemism for Caatinga biome, and
the highest abundance was recorded in the rainy season, which suggests Collembola
sensitivity to low humidity. Four species were more abundant in the dry season, all of them
belonged to the Order Entomobryomorpha. Results of statistical analyzes suggest that plant
species richness, aerial biomass of vegetal structure, proportion of sand in the soil, pH and
humidity are the main influences to the abundance of Collembola in the region studied | |
