Previous issue date: 2009-06-26 / The composition of termite assemblages was analyzed at three Caatinga sites of the Serid? Ecological Station, located in the municipality of Serra Negra do Norte, in the state of Rio Grande do Norte, Brazil. These sites have been subjected to selective logging, and cleared for pasture and farming. A standardized sampling protocol for termite assemblages (30h/person/site) was conducted between September 2007 and February 2009. At each site we measured environmental variables, such as soil granulometry, pH and organic matter, necromass stock, vegetation height, tree density, stem diameter at ankle height (DAH) and the largest and the smallest crown width. Ten species of termites, belonging to eight genera and three families, were found at the three experimental sites. Four feeding-groups were sampled: wood-feeders, soil-feeders, wood-soil interface feeders and leaf-feeders. The wood-feeders were dominant in number of species and number of encounters at all sites. In general, the sites were not significantly different in relation to the environmental variables measured. The same pattern was observed for termite assemblages, where no significant differences in species richness, relative abundance and taxonomic and functional composition were observed between the three sites. The agreement between the composition of assemblages and environmental variables reinforces the potential of termites as biological indicators of habitat quality / A composi??o das taxocenoses de t?rmitas foi analisada em tr?s ?reas de Caatinga na Esta??o Ecol?gica do Serid?, localizada no munic?pio de Serra Negra do Norte, Estado do Rio Grande do Norte, Brasil. As tr?s ?reas sofreram cortes seletivos e foram utilizadas para atividades de pastagem e agricultura. No per?odo de setembro de 2007 a fevereiro de 2009 foi aplicado um protocolo padronizado de amostragem de t?rmitas e vari?veis ambientais foram mensuradas em cada ?rea, como granulometria, pH e mat?ria org?nica do solo, estoque de necromassa, altura da vegeta??o, densidade de ?rvores, di?metro dos caules ? altura do tornozelo (DAT) e comprimento maior e menor das copas. Foram encontradas 10 esp?cies de t?rmitas pertencentes a oito g?neros nas tr?s ?reas estudadas. Al?m disso, foram identificados quatro grupos alimentares: consumidores de madeira, consumidores de h?mus, consumidores de madeira/h?mus e consumidores de folhas. Os consumidores de madeira foram dominantes em todas as ?reas, tanto em n?mero de esp?cies quanto em n?mero de encontros. No geral, as ?reas n?o foram significativamente diferentes em rela??o ?s vari?veis ambientais mensuradas. O mesmo padr?o foi observado para as taxocenoses de t?rmitas, n?o havendo diferen?a significativa da riqueza de esp?cies, abund?ncia relativa e composi??o dos grupos alimentares e taxon?micos entre as tr?s ?reas. A sintonia entre a composi??o das taxocenoses e as vari?veis ambientais refor?a o potencial dos t?rmitas como indicadores biol?gicos de qualidade de habitat
