Sampling oribatid mites in large areas using conventional methods is expensive, time-consuming,
and this constrains their use in environmental monitoring programs. We used samples collected
in 38 plots of 3.75 ha spread over 30,000 ha in an Amazonian savanna to evaluate the reduction
in costs and person-hours in sampling and sorting and to elaborate cost-effective protocols. Ten
samples per plot were collected and extracted using a Berlese-Tullgren apparatus. In the
laboratory, samples were reduced to 50, 25, 12.5 and 6.25 percent of the initial content. Fieldeffort
reduction was estimated by reducing the number of subsamples per plot. Dissimilarity
matrices were generated using Bray-Curtis, Sørensen and Chao-Sørensen indices. Correlations
between each reduced-effort dissimilarity matrix and 100 or 50 percent sorting were used as an
index of how much information was retained in reduced-effort sampling, and could still be used
in multivariate analyses. The effects of most predictor variables on mite composition were
detected in data based on every level of sample reduction. The intensive sampling was insufficient
to reveal the full oribatid-mite fauna in the savanna; as more plots were sampled, more species
were recorded. Our data indicate sub-sampling protocols for biodiversity assessment of oribatid
mites in savanna that increase field and labor efficiency, and optimize both taxonomic and
ecological aspects of the investigation.
