The number of samples to collect in the field and sorting reduction in the laboratory are important
issues for processing ants collected during long-term study. We have conducted a pilot
investigation to evaluate the reduction in costs and time in mounting, labeling, and identifying
ant, and to elaborate cost-effective protocols. We used samples collected for a single period in
24 transects of 100 m distributed in six 600 ha plots spread over 33,000 ha of primary forest in
the Brazilian State of Pará, Brazil, as part of a long-term project planned to execute four sampling
periods a year during 10 years (Tropical Ecology Assessment and Monitoring Initiative, TEAM,
Ants Methodology Protocol). Ten samples were taken per transect using the extractor of Winkler.
Ants were identified to genus and Crematogaster, Gnamptogenys and Pachycondyla genera to
species level. Field-effort reduction was estimated by diminishing the number of samples per
transect. Multidimensional scaling (MDS) was used to generate dissimilarity matrixes and then
Mantel correlations between each reduced-sampling effort dissimilarity matrix and the maximum
effort were used as an index of how much information was maintained, and could still be used in
multivariate analyses. We registered 44 genera of ants. Considering the genera identified to
species level, we found 19 species and 6 morphospecies; 3 taxa are considered new, 5 are
new records for the state of Pará, and 11 for the study site. We found that the composition of the
communities in the inventory could be represented in lower number of samples per transect, but
in different levels of reduction for each taxonomical grouping. Considering the environmental
variables (sand percentage, litter volume, and soil pH) and the maximum effort, a consistent
trend of lower values was detected in capturing the effect of litter volume for the community of
Crematogaster, and soil pH for the community of genera. The trend was still detectable in the
subsequent analysis based on reduced-sampling. These results indicate that the initial protocol
of the long-term project can be optimized to increase field and laboratory cost-efficiency. Other
experiments are needed encompassing replicates of several sampling periods to ensure if the
observed tendencies can be reproduced.
