Abstract

Relatively few studies in temperate environments have compared pitfall traps and Winkler litter samples, two of the most commonly used ant (Formicidae) sampling protocols. Most of the comparative work has been performed in tropical and subtropical environments. Temperate studies have primarily taken place in forested environments. Our study focuses on the relative efficiency of these two methods in temperate oak savannas, the major ecotone connecting grasslands and deciduous forest in the Midwest. These environments are often maintained by fire and mechanical brush removal, which tends to decrease the amount of available leaf litter. We sampled 21 sites, varying in age since restoration from un-restored to 22 years of restoration activities in McHenry Co. Illinois. Each site was sampled with 30 pitfall traps and five Winkler litter samples. A total of 38 species in 17 genera in 5 subfamilies were captured and identified. Pitfall traps accounted for 37 of the species, while Winkler litter samples only captured 23 species, and only one species specific to that method. We conclude that in northern temperate savannas, pitfall traps were more effective and more efficient at characterizing the epigeic ant community than Winkler litter samples.

Abstract: Wildfires are of increasing concern in light of climate change, more frequent late summer droughts, and increasing incidence of human ignitions. There have been few studies examining the effects of wildland fires on soil macroinvertebrates in the Blue Ridge Mountains, in spite of the importance of these animals to soil processes, and their contributions to the biodiversity of these ecosystems. During November and December of 2016, the southeastern USA experienced numerous, large wildfires. These fires offered an opportunity to study the effects of wildland fire on soil macroinvertebrates. We sampled plots from three different wildfires in North Georgia and Tennessee, each plot with five burned plots and five unburned plots. These sites were sampled seasonally from 2017 through 2020. At each plot, on each date, we collected macroinvertebrates by hand sorting both litter (4 m diameter plots) and mineral soil monoliths (30 x 30 x 30 cm) for 30 person-minutes each. All macroinvertebrates were identified to morphospecies. One focal taxon, millipedes, were identified to species. Abundance, species richness, and several diversity metrics (abundance and richness) were calculated to compare the macroinvertebrate communities of the burned areas to those in the unburned areas to better understand their response to fire.
