The effects of road crossings on fish communities have been extensively studied; yet little attention has been given to macroinvertebrate communities. This study evaluated physical stream characteristics, water quality, and aquatic-insect richness from above and below road crossings of low-order streams in the Ouachita National Forest in Arkansas. Fifteen road crossings were sampled during October and November 2005. Erosion was significantly higher below road crossings than above. Sites downstream of road crossings had significantly lower pH and significantly higher turbidity than sites upstream of road crossings. Despite differences in water quality and habitat, there was no apparent difference in aquatic-insect …

Ants (Hymenoptera: Formicidae) Of Arkansas Post National Memorial, David M. General, Lynne C. Thompson
Journal of the Arkansas Academy of Science
A combination of techniques was used to collect ants at the Arkansas Post National Memorial, Arkansas County. The techniques were wood breaking, leaf-litter sifting with Berlese extraction, tree baiting, pitfall trapping, and visual searching. Twenty-five genera and 46 species were collected. Three genera are new distributional records for the state: namely, Discothyrea, Proceratium, Protomognathus, and Strumigenys.. Nine species are new state records. Fourteen of the genera and 32 of the species collected are new records for Arkansas County.
