Abstract
Ground-dwelling ants build underground nests in peatland areas that have been
converted into acacia plantation (“HTI”). The activity of the ants, such as bringing
foods into their nests and excreting can alter the substrate availability for
microorganisms in belowground environments. The present study is a preliminary
investigation of the effect of ground-dwelling ant activity on the microbiological
properties of subsurface peat. Samples of ants nest and peat were collected from Bukit
Batu area in Bengkalis District, Riau Province. Peat inhabited by ants showed larger
microbial C biomass (1461,83 C/hour/g sample) and hence the control peat (104,88
C/hour/g sample). The former (possibly also) demonstrated higher respiration rate
(233,72 μg CO2/m2/hour). However, ant acitivities in their nests decreased total
population of cellulolytic bacteria (9,3x103 CFU/g sample), hence also the cellulase activity (0,17 μg/hour/g sample)
