Book Summer Ecology of the Indiana Bat

Download or read book Summer Ecology of the Indiana Bat written by Andrew Broni Kniowski and published by . This book was released on 2011 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.

Book Summer Ecology of the Indiana Bat Myotis Sodalis in an Agricultural Landscape

This book was released on 2011 with total page 95 pages. Available in PDF, EPUB and Kindle. 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.

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.

Book Migration Ecology of Female Indiana Bats myotis Sodalis in Spring

Download or read book Migration Ecology of Female Indiana Bats myotis Sodalis in Spring written by Arin Michelle Vann and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Indiana bat (Myotis sodalis) has been listed as a federally endangered species since 1967 due to numerous natural and anthropogenic threats. Research on the species has focused on hibernacula and maternity colonies, but data gaps exist in portions of their range. To prevent further decline, migration resources need protection, but management practices are difficult to implement without having precise data on migration routes. I documented spring migration in Arkansas using aerial and ground telemetry during 2017-2018. Radio transmitters were affixed to 52 female M. sodalis during 2017 and 2018 of which 23 were successfully tracked. I located roost trees via ground telemetry and documented their characteristics. Of the 23 tracked bats, 10 migrated east, six migrated north, five migrated south, and three remained in staging trees. These results may assist in uncovering additional information related to migration routes and maternity colonies of M. sodalis in the future. Results of my study suggest that female M. sodalis likely form maternity colonies in Arkansas.
