- Incidence of epigeal nest-building termites in Brachiaria pastures in the Cerrado Maria Inês Lopes de Oliveira Didier Brunet Danielle Mitja Wellington dos Santos Cardoso Norton Pólo Benito Maria de Fátima Guimarães Michel Brossard Agrociencias termite soil macrofauna Turned soil volume This study aimed to determine the number of termite epigeal nests and estimate the soil turning capacity of termites in cultivated pasture environments and in a native vegetation area. Surveys were conducted in four areas: three pasture areas and a Cerrado area, measuring 5 ha each. For each nest, the height, the perimeter and diameter at the base were measured. The volume of each mound was calculated. Turned soil was determined by randomly sampling 30 termite mounds in a pasture area for bulk density determinations. The mean number of termite mounds per ha was 408; the highest number of termite nests (672 per ha) was found in the 10-year-old pasture. In terms of termite mound density, there was no difference between the Cerrado, 3-year-old pasture, and 3-year-old intercropped pasture treatments. The total area occupied by termite nests ranged from 0.4 to 1.0%. The mean bulk density of the nest materials was 1.05 g cm-3. The total nests volume ranged from 4 to 11 m3 ha-1. The total mass of the soil turned by the termites ranged from 3.4 to 13.4 ton. ha-1. 2011 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303026595015 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
