Turtles are among the vertebrate taxa most affected by roads because of their low vagility and use of road and road-side habitats. In 2013, Wayne National Forest in southeastern Ohio was bisected by a new highway, affecting a road-naive population of eastern box turtles (<i>Terrapene carolina carolina</i>), a species of concern in Ohio and vulnerable throughout its range. The goal of this study was to evaluate ecological, physiological, and behavioral effects of proximity to this new road in this road-naive population of turtles. We used a control-impact study to evaluate potential ecological and physiological effects of proximity to roads, employing radio-telemetry to assess space use, movement behavior, and habitat selection. We used novel bioassay techniques to analyze indicators of chronic stress (across the prior several months) using corticosterone stored in nail keratin. Overall, we found no significant differences in home range sizes, habitat preferences, or corticosterone concentrations between road-side and control sites. While our work suggests that proximity to roads has limited indirect influence on the ecology and chronic stress responses of eastern box turtles, and that road-naive turtles demonstrated avoidance of a high-traffic highway, the road network likely continues to contribute to population declines through direct mortality, and further inquiry is needed to assess road effects, particularly in the areas of stress endocrinology and impacts on demography. 2018-10-01 English text Ohio University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1534258446656083 http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1534258446656083 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
