Book excerpt: Although bats are often thought of as cave dwellers, many species depend on forests for all or part of the year. Of the 45 species of bats in North America, more than half depend on forests, using the bark of trees, tree cavities, or canopy foliage as roosting sites. Over the past two decades it has become increasingly clear that bat conservation and management are strongly linked to the health of forests within their range. Initially driven by concern for endangered species—the Indiana bat, for example—forest ecologists, timber managers, government agencies, and conservation organizations have been altering management plans and silvicultural practices to better accommodate bat species. Bats in Forests presents the work of a variety of experts who address many aspects of the ecology and conservation of bats. The chapter authors describe bat behavior, including the selection of roosts, foraging patterns, and seasonal migration as they relate to forests. They also discuss forest management and its influence on bat habitat. Both public lands and privately owned forests are considered, as well as techniques for monitoring bat populations and activity. The important role bats play in the ecology of forests—from control of insects to nutrient recycling—is revealed by a number of authors. Bat ecologists, bat conservationists, forest ecologists, and forest managers will find in this book an indispensable synthesis of the topics that concern them.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that 95% of all federally endangered Indiana bats (Myotis sodalis) hibernate in 71 hibernacula in the eastern US. Given the species0́9 high site fidelity, seasonally heightened population densities, and the limited availability of suitable overwintering sites, land use and cover change (LUCC) near hibernacula is expected to affect wintering populations. The landscapes surrounding hibernacula not only provide critical roosting and foraging habitat but also support the highly specific microclimates Indiana bats need for successful hibernation. To date, the assumption has been that the greater the amount of forest cover, the better the habitat for Indiana bats. The extent to which Indiana bat hibernacula may be threatened by LUCC has not been previously investigated. Land adjacent to most hibernacula does not have land use or conservation protections; consequently, it is important that LUCC near hibernacula is evaluated to assess and prevent harmful impacts to wintering Indiana bat populations. Landscape characterizations included measurements of land cover composition and spatial configurations, as well as climate and insolation variables. I modeled potential future LUCC through 2016 near 225 Indiana bat hibernacula using an empirically derived, stochastic projection model that combines Markov chain analysis, multi-criteria evaluation, and cellular automata. Drivers of the model included biophysical and socioeconomic variables. Characterization and modeling were performed at two spatial extents and at several management groupings chosen for their relevance to the species0́9 biology and conservation. Two spatial extents approximating areas expected to be used by bats were considered, owing to the importance of scale in species habitat use. The change in the forest proportion of the landscape ranged from 7.38 - 98.99% (mean 74.42% ± 2.31% [90% CI]) in 1992, 4.91 - 95.142% (66.99% ± 2.12%) in 2001, and a projected 3.33 - 78.09% (47.75% ± 2.15%) in 2016. This change represents a 26.67% decrease in the mean proportion of forest surrounding hibernacula projected over 24 years. The mean proportion of developed land was projected to increase by 7.82% by 2016. The extent to which these rates of change in land use and cover will support conservation of the Indiana bat is an important question. LUCC has and will likely trend towards more-isolated forest patches and, in some cases, extremely heterogeneous landscapes. Results indicate that bat populations might best be supported by a certain degree and type of landscape heterogeneity rather than by maximum contiguous forest cover. The major findings of this research are: 1.) Hibernacula with greatest Indiana bat population counts were surrounded by landscapes that were more heterogeneous than hibernacula with lower counts. Bat populations at hibernacula were not highly correlated with forest cover alone as had been predicted. 2.) Privately-owned hibernacula had more heterogeneous landscapes than federally-owned hibernacula. 3.) Landscapes describing the smaller, more proximal expected use area near hibernacula were less heterogeneous than those for the larger expected use area. 4.) Forest cover declined and is projected to decline further in every landscape surrounding hibernacula in this study. 5.) There was no clear pattern among landscape variables and geographic or management groupings. 6.) There was a linear relationship between Indiana bat population counts and landscape variables, including insolation, edge density, and proportion of forest cover.

Book excerpt: Abstract: The majority of the summer range of the Indiana bat (Myotis sodalis) is within agricultural areas, yet despite known negative effects of agriculture, few studies have examined the ecology of the Indiana bat within a highly agricultural landscape. To evaluate the effects of agriculture on Indiana bats I asked the following questions: 1. Do Indiana bats selectively use habitat within an agriculturally-dominated landscape? 2. Do Indiana bats select habitat differently at different spatial scales within an agricultural landscape? And 3. Do Indiana bats select and use habitat within an agricultural landscape differently than other areas of their range? From a study area along Big Darby Creek in Pickaway Co. Ohio USA, I captured 60 Indiana bats (including five recaptured bats) July-September 2008, April-September 2009, and April-September 2010. I calculated home ranges of 32 individuals that had an average area of 210.5 ha ± 130.6 SD. I used distance based analysis to evaluate habitat selection within the home range, and at 1200 m and 4000 m spatial scales. At each scale, bats selected areas closer to forest and open water and farther from cropland than was expected by chance. The bats heavily used the wooded creek corridor, but also utilized wooded patches in upland areas. I tracked 51 bats to 56 roost trees 474 times. The bats used roost trees in a variety of locations and across a broad area. Most roost trees were located within the wooded creek corridor, but seven were more than 1 km from open water. I evaluated the location of roost trees within the landscape at 1200 m and 4000 m spatial scales. Roost trees were not located randomly at either spatial scale. The only significant factor in both cases was the distance to open water. There was also was a significant difference in physical characteristics of used and available roost trees (A = 0.257, P = 0.025) and primary and secondary roost trees (A = 0.032, P = 0.013). Widely scattered roosts suggest Indiana bat colonies use a broad area within the context of an agricultural landscape. The selection of habitats in a highly agricultural landscape appears similar to other landscapes and the selection is consistent over a broad range of spatial scales. Preserving forested areas with ample supplies of snags within agricultural landscapes, including smaller patches and especially along waterways, should be a conservation priority for the Indiana bat.

This book was released on 2011 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: The federally endangered Indiana bat (Myotis sodalis) uses fragmented forests in largely agricultural landscapes during the maternity season. Understanding how land use and land management affect bat activity and insect prey availability would provide insight into resource needs of Indiana bats. We had three main objectives, first to determine resource selection by foraging Indiana bats during the maternity season and to compare resource use among pregnant and lactating individuals. Second, we sought to estimate home range size using utilization distributions for individual Indiana bats. Finally, we wanted to determine if we could predict Indiana bat activity by using habitat, weather, and prey availability data within our study area. We used an information theoretic approach to examine a priori models for our first and third objective. To evaluate our second objective, we used telemetry data to calculate the area within 50% and 95% probability contours of utilization distributions estimated by the fixed kernel method. We found variation among individuals in resource selection and home range size. Indiana bat activity was higher in areas managed by prescribed fire and with high percent canopy cover, and at sites with higher dry insect biomass collected in malaise traps. We believe prescribed fire benefitted bats by reducing understory clutter. In contrast, forest management practices that greatly reduce canopy cover may have a negative impact on Indiana bats.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The extensive forested uplands of Morgan-Monroe and Yellowwood State Forests (MMYSF) in southern Indiana are largely composed of ephemeral streams. The Indiana Department of Natural Resources created ponds within the state forests to provide year-round fresh water for wildlife. The goal of this study was to document bat activity at these ponds, and determine what habitat attributes influence bat activity levels. In 2018 and 2019, we conducted acoustic surveys at 25 ponds, and temporally paired sites in the surrounding forest, during the summer months. Vegetation structure surveys were conducted at each pond to quantify habitat attributes that could affect bat activity, and aquatic fauna surveys were used as a surrogate for water quality. Results showed that bat activity was significantly higher at ponds than forest sites. A two-way ANOVA revealed that only two of 25 ponds surveyed had significantly more bat activity than the average, and results were consistent between years. According to a random forest model, the amount of vegetation surrounding ponds had the strongest relationship with bat activity compared to the other variables. Ponds with the highest bat activity had the following characteristics:

This book was released on 2019 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goals of my thesis are to: 1) identify species of bats in Wright State University's (WSU) campus woods via acoustic surveys to compare to detections from previous years (Chapter 1) (2) analyze occupancy and detection probabilities of Indiana bats in different areas throughout the woods (Chapter 1), and 3) create an acoustical approach to analyze habitat use through bat social calls (Chapter 2). In Chapter 1, I conducted stationary acoustic surveys in the Wright State University woods in hydric (riparian), edge, and old growth habitats to record bat vocalizations. The WSU woods have a diverse bat community as ten out of eleven possible bat species were detected. Furthermore, foraging habitat selection was species-specific, and could be driven by wing loading and competitive exclusion. Indiana bat occupancy was consistent throughout the woods; habitat did not affect occupancy. Indiana bat detection was not affected by habitat or precipitation but was positively correlated with temperature. As temperatures increased, bat detection probabilities also increased. In Chapter 2, I conducted stationary acoustic surveys in the WSU woods in riparian, edge, and old-growth habitats to record Indiana bat social calls. The WSU woods housed federally endangered bats, and likely Indiana bat maternal roost sites indicated by the presence of isolation calls. This study also demonstrated that habitat analysis using social calls is a viable way to detect quality foraging areas and maternal roost sites
