The Application Of Chitosan On An Experimental Infection Of Pseudogymnoascus Destructans Increases Survival In Little Brown Bats, Torin C. Kulhanek

Masters Theses

This research builds upon a previous study conducted that tested the efficacy of chitosan on experimentally-infected bats as a laboratory model of White-nose syndrome. White-nose syndrome is a fungal infection caused by Pseudogymnoascus destructans, formerly known as Geomyces destructans. The pathology of this disease is not yet fully understood, but it is devastating bats throughout Northeastern America and continues to spread. Here we tested multiple application time points and concentrations of chitosan on the wings of experimentally-infected bats and compared them with the controls. We grossly viewed the wings first to get a sense of the amount of …

Acoustic Evidence Of Bats Using Rock Crevices In Winter: A Call For More Research On Winter Roosts In North America, Cliff A. Lemen, Patricia W. Freeman, Jeremy A. White

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The Northern Long-eared Myotis (Myotis septentrionalis) is known to hibernate in mines and caves, often using cracks within these hibernacula as roost sites. We hypothesized that M. septentrionalis might use deep cracks in rock outcrops for hibernation as well. To test this hypothesis, we placed acoustical bat detectors near rock outcrops away from any known mines or caves during winter in Nebraska. We documented calls of M. septentrionalis as well as Perimyotis subflavus and Eptesicus fuscus in December near rock outcrops, which suggests that individuals of all three species were hibernating in rock crevices in winter. Of the …

Winter Activity Of Myotis Septentrionalis: Role Of Temperature In Controlling Emergence From A Hibernaculum, Cliff A. Lemen, Patricia Freeman, Jeremy A. White

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

We acoustically monitored a small mine in southeastern Nebraska known to be a hibernaculum for the Northern Long-eared Myotis (Myotis septentrionalis) for two winters (2014-2015 and 2015-2016). Some M. septentrionalis emerged on nights with mild temperatures throughout both winters. There was an 89% probability of detecting this species when temperature at sunset was >5°C. Our results indicated that acoustical surveys outside mines or caves in winter, particularly on nights with mild temperatures, are an effective method of identifying hibernacula of M. septentrionalis and potentially other species without disturbing individuals by entering the hibernaculum or by netting individuals as …

Maternity Colony Of Northern Long-Eared Myotis (Myotis Septentrionalis) In A Human-Made Structure In Nebraska, Rachel M. Stein, Jeremy A. White

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The Northern Long-eared Myotis (Myotis septentrionalis) occurs across eastern North America, and its range extends west into the Great Plains of the United States. Summer roosts of M. septentrionalis in the Great Plains are not well documented. Herein we describe a maternity colony of M. septentrionalis using small, elevated structures (i.e., cabins) in southeastern Nebraska. Cabins were in a small parcel of upland deciduous forest about 1.6 km from the Missouri River. The maternity colony was observed roosting in a space between the outer and inner walls of three different cabins from 21 June to 8 October 2014. …

Bats Serves As Nebraska's Natural Pest Control Agents, Michael Whitby, Craig R. Allen

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

You don't notice them flying in the night sky as you drive home, or in the trees above you as you walk your dog or under the bark of the dead tree at your fishing hole, but bats are everywhere in Nebraska. In fact, there are 13 species of bats inhabiting our state. They exhibit a wide variety of shapes, sizes and colors. Some migrate to unknown locations each winter. others stay in Nebraska and hibernate in caves, mines and occasionally homes. You probably won't notice them unless you happen to catch a glimpse of one eating insects under a …

Assessing The Effects Of Prescribed Fire On Foraging Bats At Mammoth Cave National Park After The Arrival Of White-Nose Syndrome, Rachael Elizabeth Griffitts

Online Theses and Dissertations

Habitat use of bats may shift following population level impacts of White-nose Syndrome (WNS). Multiple bat species have experienced unprecedented population declines due to WNS, including federally listed Myotis sodalis (Indiana bat) and Myotis septentrionalis (northern long-eared bat). Specifically, the effect of WNS across forest landscapes is unclear in relation to prescribed fire. Mammoth Cave National Park (MACA) has employed a prescribed fire regime since 2002 and WNS was detected on MACA in 2013. Bat activity was monitored across burned and unburned sites at MACA before (2010-2012) and after the detection of WNS (2013-2016) using transects of acoustic detectors (Anabat …

Wind Energy Development: Methods For Assessing Risks To Birds And Bats Pre-Construction, Todd Katzner, Victoria Bennett, Tricia Miller, Adam Duerr, Melissa Braham, Amanda Hale

Human–Wildlife Interactions

Wind power generation is rapidly expanding. Although wind power is a low-carbon source of energy, it can impact negatively birds and bats, either directly through fatality or indirectly by displacement or habitat loss. Pre-construction risk assessment at wind facilities within the United States is usually required only on public lands. When conducted, it generally involves a 3-tier process, with each step leading to more detailed and rigorous surveys. Preliminary site assessment (U.S. Fish and Wildlife Service, Tier 1) is usually conducted remotely and involves evaluation of existing databases and published materials. If potentially at-risk wildlife are present and the developer …

Mitigating Wind Energy Impacts On Wildlife: Approaches For Multiple Taxa, Edward B. Arnett, Roel F. May

Human–Wildlife Interactions

Mitigating impacts of wind energy development on wildlife is important for conservation and public acceptance of this energy source. We provide an overview of approaches to mitigate impacts of onshore wind energy development on wildlife, following steps in the mitigation hierarchy, including avoidance, minimization, and compensatory mitigation. Planning and avoiding predicted high-risk areas is fundamental to reduce impacts on birds and bats. Contrary to avoidance, once facilities are built, options to minimize impacts need to be tailored to species at the specifc site, and can be limited especially for bats. Curtailing wind turbine operations is the only approach proven effective …

Bat Ectoparasites Of Mongolia, Part 3, Ingo Scheffler, Ariunbold Jargalsaikhan, Idertsogt Bolorchimeg, Annegret Stubbe, Michael Stubbe, Andreas Abraham, K. Thiele

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The fauna of Mongolian bats and their ectoparasites is not yet fully documented. This study analyzes ectoparasite samples of 15 bat species from diverse taiga, steppe, and desert locations. We recorded 27 parasite species in total and report their abundance, host preference, and occurrence herein. In describing a new bat fly species (Basilia dolchii n. spec.), reporting six parasite species never before recorded in Mongolia, and examining rare host species such as Myotis frater and Murina hilgendorfi, this work expands present knowledge in this research area. To assess respective individual and species-specific parasite loads comprised of different insects …

Structure Of Summer Bat Assemblages In Forests In European Russia, Anton Vlaschenko, Kseniia Kravchenko, Alona Prylutska, Elena Ivancheva, Elena Sitnikova, Alexander Mishin

Turkish Journal of Zoology

We used mist-netting to study summer bat assemblages in 3 state nature biosphere reserves in the European part of Russia from 26 June to 29 July 2013: Oksky, Ryazan region (54°44'N, 40°54'E); Voronezhsky, Voronezh region (51°55'N, 39°38'E); and "Bryansky Les", Bryansk region (52°27'N, 33°53'E). The main research efforts were in locations where Nyctalus lasiopterus had been captured in the past. In total, 1229 specimens of 12 bat species (Myotis daubentonii, M. dasycneme, M. brandtii, M. mystacinus, Nyctalus noctula, N. lasiopterus, N. leisleri, Eptesicus serotinus, Pipistrellus nathusii, P. pygmaeus, Vespertilio murinus, and Plecotus auritus) were caught. N. lasiopterus (a female subadult) …
