Termite activity in relation to natural grassland soil attributes

Abstract: Soil-feeding termites transport soil for mound building, and this process can affect soil characteristics. To verify the influence of soil termite activity on soil characteristics, samples were collected from top, bottom and center of termite mounds, and of the adjacent area, to assess chemical and physical properties and mineralogical composition. Four replicates of termite mounds and respective adjacent areas were randomly sampled in Lages, Capão Alto, Painel, São José do Cerrito and Coxilha Rica (State of S… Show more

“…Jones [7], studying termite tunnelling through treated soil, proposed a similar mechanism to explain why larger groups of termites could tunnel deeper than smaller ones, with relative mortality being lower in larger groups. It was claimed that the larger the group, the more could tasks be shared, giving more individuals at any time the chance to loaf, rather than having to be involved in tunneling and maintenance tasks most of the time, as in small groups [40][41][42][43][44]. Our results have important practical implications, too.…”

“…Considerouse macrofauna de solo os indivíduos entre 4 e 80 mm de diâmetro (Vargas & Hungria, 1997;Kaschuk et al, 2006 (Gray, 1999). O SCI é uma ferramenta que quantifica a diversidade de ecossistemas e compara a diversidade de diferentes locais.…”

“…Entretanto, a matéria orgânica no substrato revegetado não se relacionou significativamente com a abundância da macrofauna de solo e apresentou fraca correlação (r = 0,50) com a diversidade de morfoespécies (SCI M ). Esses resultados, os hábitos e as estratégias de sobrevivência desse grupo (Wolters, 2000;Kaschuk et al, 2006) sugerem que a macrofauna identificada utilizava-se mais da vegetação na jazida do que da matéria orgânica no substrato.…”

“…Nevertheless, these studies were conducted in pasture areas and/or areas of natural regeneration of native vegetation, and there is no data of this kind referring to eucalyptus plantations, which is a type of soil management widely used in many different soil and climatic conditions. In addition, information about the effect of termite activity on soil, by comparing different sections within termite nests in a vertical gradient (top, center, and base), and comparing these sections to the surrounding soil, were reported by Kaschuk et al (2006). This type of approach is based on the hypothesis that the different sections have different chemical compositions.…”
