Therefore, it was concluded that these methods were complementary for ant diversity inventories in the Poconé Pantanal region.Īdis J (2002) Recommended sampling techniques. The Principal coordinates analysis discriminated two species groups exclusively sampled by the mini-Winkler extractor and another by the pitfall methods. A significant difference between the methods was observed in measured species number. biconstricta) sp.1 were the most frequent species. Using pitfall traps, 2,726 individuals distributed in 24 genera and 48 species were sampled and Dorymyrmex (gr. biconstricta) sp.1 as the most frequent ants. Using the mini-Winkler extractor, 1,088 individuals were collected distributed in 20 genera and 55 species, with Solenopsis invicta Buren and Pheidole (gr. ![]() A collection was made at each sampling point with mini-Winkler extractor and pitfall traps. Five collection points were marked in each transect at 50-m intervals, totaling 150 points. Seven units were studied for landscape, located within a 25 km 2 collection area, formed by thirty 250-m transects, at 1-km intervals in a 5 × 5 km area. The application of both techniques should be considered if the aims of a study require estimation of community properties, such as relative abundance.The aim of the present study was to evaluate the use of mini-Winkler extractor and pitfall traps as appropriate and complementary methods to sample ant communities in the phytophysiognomy mosaic in the Poconé Pantanal region, state of Mato Grosso, Brasil. Either technique adequately collected samples for broad comparisons and documentation of the more typical and representative ant fauna, but Winkler extraction exhibited the advantage of a more complete inventory. Site variation had little effect on the inherent differences in sampling efficacy between the two methods. According to estimates of expected species richness, the combination of the two sampling techniques allowed for the collection of ≈90% of the ants expected in the surveyed area. Consistent with other studies, Winkler sampling was found to catch a greater number of smaller ants, whereas pitfall trapping caught a greater number of large-bodied ants. Winkler samples accumulated species more rapidly than did pitfall traps and had greater total species richness and higher abundance of ants recorded. Winklers captured all 31 species, whereas pitfall traps collected a total of 24 species. ![]() During 2005–2006, 90 Winkler and 180 pitfall trap samples from urban forest fragments in northeastern Ohio obtained 9,203 ants representing 31 species. Both techniques are among the most common methods used to measure the diversity of organisms active on the forest floor. The sampling efficiency of pitfall traps and Winkler litter extraction in northern deciduous forests was compared using ants.
