Local Scale Comparisons Of Avian And Woody Vegetation Communities Within Four Arkansas State Parks, Bennett P. Grooms, Rachael E. Urbanek

Measuring the spatial distribution of biotic communities can provide useful data to wildlife managers on how and why species assemblages differ across a landscape. During 18 May – 7 August 2015, we conducted avian point counts and collected vegetation data in nested subplots at 4 Arkansas state parks. We then used a series of one-way ANOVAs and Kruskal-Wallis tests to examine differences in species richness, Simpson’s evenness, Simpson’s diversity, and Bray-Curtis similarity across the 4 parks. Mount Magazine State Park had the lowest avian evenness (F3,22 = 9.57 P = 0.003) and diversity (F3,22 = 17.8 …

Four springs were surveyed at Hobbs State Park-Conservation Area to provide an initial bioassessment and to determine occurrences of two endemic predaceous diving beetles of concern, Heterosternuta sulphuria and Sanfilippodytes sp. Habitat in the four spring runs were dominated by bedrock and gravel substrate with heavy accumulations of leaf litter. Thirty-three taxa representing 11 orders were collected from the four springs. Non-insect taxa included Oligochaeta, Physidae, and Isopoda, and predominant insect orders included Ephemeroptera, Coleoptera, Diptera, and Trichoptera. The total number of taxa across springs ranged from seven to 19, with total abundances ranging from 39 to 86 individuals. No …
