The Indiana bat (Myotis sodalis) is a tree roosting species found throughout the eastern United States that is federally listed as endangered by the U.S. Fish and Wildlife Service. A more detailed understanding of summer roosting and foraging habitat for Indiana bats is needed for effective conservation and management. The objectives of this research included identifying and describing aspects of the summer ecology of this species, especially selection of tree roosts and foraging habitat in the Big Darby Creek area in Ohio. During the 2008-2010 seasons, we captured 55 Indiana bats and radiotracked 51 individuals. We tracked bats to 56 roost trees 474 times (bat roost days). Roosts were largely clustered in riparian woodland habitat along the Big Darby Creek. Roost trees were of 11 different species but two of the trees could not be identified. Eight of the trees were alive, two were declining, and the rest were dead or in a greater stage of decay. Roost trees were found relatively close to water, and tended to be dead or decaying, a high percentage of loose bark, and a dominant canopy class, when compared to other available trees. We calculated 33 home ranges. Average home range size was 210.5 ± 130.6 SD ha (0.84 ± 0.52 SD mi2) for fixed kernel and 374.2 ± 359.6 SD ha (1.49 ± 1.44 SD mi2) for minimum convex polygon. Bats selected for woodland and water habitats, and avoided cropland at multiple spatial scales. Although most foraging flights occurred within the riparian corridor, bats also moved outside the corridor to upland areas.

The goal of my thesis is to: 1) provide baseline information of where Ohio bats are foraging in Wright State University's (WSU) campus woods in relation to forest age and habitat (Chapter 1), 2) determine potential roost availability for local bats (Chapter 1), and 3) examine changes in state-wide species composition following the introduction of White-nose Syndrome (WNS; Chapter 2). In Chapter 1, I created walking bat acoustic routes and used generalized linear models to determine what forest ages and habitats had the greatest bat activity in the WSU campus woods. I conducted habitat transects throughout all forest ages to estimate and contrast their available bat roost tree densities. My results supported species-specific trends in foraging habitat selection, and could further be explained by bat flight morphology. Selection of edge habitats in primary and secondary forests was consistent among species, while variation was large among interior and riparian habitats. Further, larger bodied species preferred edge habitats for foraging while midsized and small bodied species had intraspecific variation in foraging habitat selection. Primary forests and secondary 65 year forests had the greatest availability of potential foliage roost densities compared to degraded primary and secondary 85 year forests. Additionally, secondary 65 year forest had the greatest availability of potential cavity roost densities compared to all other ages. Taken together, the WSU campus woods has habitats that sustain bat foraging and likely summer roosting. In Chapter 2, I used mobile bat acoustic data from Ohio Division of Wildlife (ODOW) to model trends in species composition over time following WNS. I created linear mixed effects models with summary acoustic detection data. To determine impacts on relative bat abundance, I created 61 formulas with varying fixed effects including species, species wintering behavior, species summer roosting behavior, year, and ODOW wildlife district. I used mobile acoustic routes as a random effect for each model. Best fit model predictions indicated relative species abundances of cave-dwelling cavity roosting bats decreasing, and migratory cavity roosting bats were increasing between 2011-2017. All foliage roosting species abundances were declining or unchanging. My results suggest a summer cavity roosting bat species turnover from more susceptible and/or affected species by WNS to migratory bats with the same summer roosting behavior. My results likely reflect a change in species composition across other WNS endemic areas, and inform state and federal future management strategies

North American bat populations have experienced precipitous declines since the introduction of white nose syndrome (WNS). However, bats in areas where WNS has become endemic have begun to respond to the disease. Response to WNS seems to be region and species specific; bats enter hibernation with more body fat, choose colder hibernacula, or show no response and continue to overwinter in the same conditions prior to WNS. A growing body of evidence also exists for bats using aboveground rock crevices, which may have implications for understanding the WNS response, but more research is required to fully understand this hibernation pattern. In this study, I gathered bat population and habitat data via visual surveys of above and belowground hibernacula and QGIS software to better understand WNS response patterns within the state. To investigate the bats’ response to WNS in belowground hibernacula, I conducted an analysis for counts of big brown bats, tricolored bats, and little brown myotis hibernating in caves, mines, and inactive railroad tunnels in relation to several environmental factors including hibernaculum temperature, pre WNS count data, presence of standing water, and density of nearby hibernacula (Chapter 1). To better understand the use of nontraditional hibernacula, I examined the relationship between numbers of big brown bats hibernating in aboveground rock crevices and several habitat features including crevice height above ground, crevice azimuth, elevation, topographic roughness, and distance to water source and nearby belowground hibernacula (Chapter 2). I found that thermally stable belowground hibernacula with standing water were important for WNS susceptible little brown myotis and tricolored bats, while less susceptible big brown bats continued to select their pre-WNS hibernacula where standing water was present. I also found that big brown bats were more likely to be found in aboveground rock crevices that were high off the ground, had high amounts of forest cover, and were at lower elevations. The data presented in this study supports that bats’ response to WNS is region and species specific, and that aboveground rock crevice hibernacula could be a vital winter refuge from WNS. Additionally, this study supports that aboveground rock crevices can function as suitable hibernacula in areas where belowground habitat is scarce, but also expands on this knowledge by showing that several species of bats use rock crevices even when belowground habitat is abundant.

The Ohio Department of Transportation (ODOT) is required to inspect bridge structures for presence of bats prior to repair, maintenance, or removal. Many bridges inspected do not contain bats, but evidence of bat presence can result in project delays, added costs, and increased impacts to listed species. This study aimed to facilitate understanding of bat use of ODOT bridges and to develop a predictive model to improve planning efficiency. Study objectives included identifying characteristics making bridges more or less likely to contain bats and using results to create a priority ranking system for future bridges inspections to avoid negatively impacting roosting bats while potentially avoiding project delays.
