Poster Board No. 51 - POPULATION GENETICS AND MIGRATION OF PEROMYCUS LEUCOPUS, A LYME DISEASE RESERVOIR SPECIES. Keaka R. Farleigh,, (Christine S. Anderson,, Capital University, Department of Biological and Environmental Sciences, 1 College Ave., Columbus OH 43209.

Peromycus leucopus, or the white-footed mouse, is widely distributed across the eastern United States. These generalist mice prefer to inhabit understory vegetation and play a critical role in the dispersal of Lyme disease. Acting as possible reservoirs for Lyme disease, white-footed mice may easily migrate throughout the landscape potentially distributing the disease. This study seeks to investigate dispersal between 2 populations in different habitats through use of bioinformatic techniques, and is the culmination of both field and laboratory work performed over the course of 2012 to 2017. Field work was completed at Capital University's Primmer Outdoor Learning Center in Logan, Ohio, in a secondary growth deciduous woodlot and an agricultural fencerow habitat. Mice were live-trapped, and tissue samples were collected and stored in 95% ethanol at -20 [degrees]C. DNA was extracted and multilocus microsatellite PCR was performed. Samples from Summer 2016 (n = 14) and 2017 (n = 14) have been genotyped using a 3100 Genetic Analyzer DNA sequencer at 5 loci to date. Statistical analysis with the programming language R using the HIERFSTAT package was used to calculate genetic variation, [F.sub.IS], and [F.sub.ST]. Results suggest that migration was bidirectional between populations. Additional loci are currently being screened, and migration between populations was estimated using Geneclass, MIGRATE, and GENEPOP. Extensive movement of mice, if confirmed, will challenge management strategies to limit the spread of Lyme disease.

Poster Board No. 52 - THE INFLUENCE OF A CONTROLLED PRE-BREEDING SEASON BURN ON BIRD SPECIES ABUNDANCE AND DIVERSITY IN A NATIVE WARM-SEASON PRAIRIE PATCH. Jolyn Shunk,, Alex Furst,, Danny Ingold,, and Jim Dooley,, Muskingum University, Biology Dept., 163 Stormont St., New Concord OH 43762.

Few studies have examined fire as a management tool for obligate grassland birds on eastern warm-season prairie patches. Line transects were conducted during the May to June 2017 breeding season on a 24-hectare warm-season tall-grass prairie patch that had been burned 3 months earlier in February 2017. Prior to burning, this patch was dominated by an accumulation of tall, dead switchgrass (Panicum virgatum), big bluestem (Andropogon gerardii) and a few forbs. The goal was to monitor for a potential change in the post-fire bird species abundance and richness compared to the pre-fire grassland bird occupancy. Prior to burning, obligate grassland species were essentially absent from the patch. In May post-burn, the mean height of the patch was Tilde30 cm and a substantial amount of bare ground persisted. In the May post-burn transects there was detected a modest number of savannah (Passerculus sandwichensis) and grasshopper (Ammodramus savannarum) sparrows, species attracted to shorter vegetation with less ground cover. Conversely, no Henslow's sparrows (A. henslowii) were detected. By June post-burn, as the mean vegetation height approached 140 cm, the dominant species once again were red-winged blackbirds (Agelaius phoeniceus), common...
