Conteúdo: | This study investigates how termites alter the organic matter in rain forests near Manaus, Brazil. Samples were collected from the outer and inner parts of typical termite nests of Nasutitermes, Termes, Embiratermes, Cornitermes, Anoplotermes, and Constrictotermes genera, as well as from the surrounding topsoil (0cm-10cm) and potential wooden food. The termite nests were signficant sinks for organic matter and its associated nutrients. The organic C contents ranged between 100g kg-1 and 500g kg-1 in the nests, compared to 17g kg-1 to 42g kg-1 in the surrounding topsoils. As lignin contents of the mounds were higher than in wood, lignin may be accumulated in preference to other organic compounds. This findings also sugests that the interior part of the nests is a region of higher organic matter turnover and lignin degradation.
