Assessing the effects of prescribed fire on foraging bats at Mammoth Cave National Park after the arrival of White-nose Syndrome
… 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 …

Assessing threats to North American bats: impacts of white-nose syndrome and climate on reproduction and survival
… emergent wildlife disease, white-nose syndrome (WNS). WNS is a fungal disease that has been causing catastrophic declines of bat populations in the eastern United States and Canada since it first emerged in 2006. The fungal pathogen, Pseudogymnoascus destructans, infects the wings, ears and nose …

Assessing the Long-term Impacts of White-nose Syndrome on Bat Communities Using Acoustic Surveys at Fort Drum Military Installation
… changing distribution of White-nose Syndrome (WNS)-affected bat species, increased reliance on acoustic monitoring is now the new "normal". As such, the ability to accurately identify individual bat species with acoustic identification programs has become increasingly important. Additionally, …

Potential environmental factors associated with the newly emerging bat white-nose syndrome in the northeastern United States: an exploratory modeling approach and case-control study
… of mortality-causing bat White-Nose Syndrome (WNS) in the Northeastern United States during 2006 prompted an immediate need for research surrounding possible causation factors influencing its spread. Due to the mysterious nature of fungal pathogens, it has been very difficult to determine how …

Acoustic sampling considerations for bats in the post-white-nose syndrome landscape
… facing new threats from white-nose syndrome (WNS) and wind energy development or have already experienced precipitous declines. Accordingly, researchers and managers need to know how to best monitor bats to document population and distribution changes, as well as where to look for persisting …

Evaluating Volatile Organic Compounds for Contact-Independent Antagonism of Pseudogymnoascus destructans and Assessing the Impact of Fungal Pigmentation on Antifungal Susceptibility
<p>White-nose syndrome (WNS), caused by the psychrophilic fungus <em>Pseudogymnoascus destructans</em>, has been implicated in the massive decline of hibernating bat populations across North America and has led to the listing of impacted species under the US endangered Species Act. Due to the …

Local impacts of White-nose Syndrome on the foraging ecology of insectivorous bats
… reagent-dependent. </p> <p>White-nose Syndrome (WNS) has devastated the insectivorous bats of eastern North America, resulting in dramatic population declines and shifting foraging niches. In Chapter 3, I investigate the effects of WNS, as well as prescribed fire and insect availability, on bat …

Changing Relationship Between Temperature and Pathogen Growth on Bats with White-nose Syndrome
… the disease dynamics of white-nose syndrome (WNS), caused by the fungal pathogen Pseudogymnoascus destructans (Pd), in little brown bats (Myotis lucifugus) across a spatiotemporal gradient. We explored the relationship between bat roosting temperatures and Pd growth rates across three phases …

Investigating how bat ectoparasites influence the skin microbiome diversity and composition in Washington State bats
<p>White-Nose Syndrome (WNS), caused by the psychrophilic pathogenic fungus Pseudogymnoascus destructans (Pd), has killed millions of bats in the eastern United States since its initial introduction in 2006 and recent expansion into the western U.S. Understanding factors that contribute to the …

Disease Status, Occupancy, and Relative Activity of Little Brown Bats (Myotis lucifugus) in the Northeastern United States
White-nose Syndrome (WNS), caused by the fungal pathogen Pseudogymnoascus destructans, has caused catastrophic declines in several North American bat species, including >90% losses in Little Brown Bats (Myotis lucifugus). Because small, remnant populations persist across the Northeast and …

Investigating biometrics of Perimyotis subflavus in traditional and nontraditional hibernacula in the Southeastern United States as it relates to susceptibility to white-nose syndrome.
… since the emergence of white-nose syndrome (WNS) and has been proposed for listing as “endangered” under the United States Endangered Species Act. Traditionally, bats use caves as hibernacula, but as anthropogenic impacts have increased so has the use of manmade structures like culverts and …

Seasonal activity patterns of bats in the Central Appalachians
… a fungal disease called White-nose Syndrome (WNS) and wind energy development. White-nose Syndrome has caused the death of millions of bats in North America, and multiple hibernating bat species are affected in the central Appalachians. Wind energy is one of the most rapidly-growing energy …

Assessment of Indiana bat reproductive condition, recapture trends, and temperatures of artificial roosts in Kentucky
… of bat species impacted by white-nose syndrome (WNS) will necessarily require population growth. I assessed reproductive capability of the endangered Indiana bat (Myotis sodalis) in Kentucky, where WNS was first detected in hibernacula in April 2011. Due to loss of fat reserves associated with …

MICROBIAL COMMENSALS OF TRICOLORED BATS IN GEORGIA AND THEIR PROBIOTIC POTENTIAL
… is the causative agent of white-nose syndrome (WNS), a disease leading to as much as a 90% decrease in some eastern United States bat populations, with select hibernacula experiencing complete extirpation of the hibernating population. To date, there is no effective scaled probiotic for WNS, but …

Arousal patterns, fungal loads, and wing damage in a surviving population of little brown bats (Myotis lucifugus)
… have shown resilience to white-nose syndrome (WNS), which is caused by the fungus Pseudogymnoascus destructans. This study evaluated the impact of environment (temperature and moisture), pathogen virulence, and host susceptibility on survival. Host response was assessed using …

Assessment of Culverts and Bridges as Roosting Habitat for Perimyotis subflavus (tri-colored bat) and Disease Transmission Corridors for Pseudogymnoascus destructans
… optimal tri-colored bat habitat and, along with WNS surveys, identify suitable habitat for developing WNS. This data addresses the knowledge gap regarding the seasonality of bat use of bridges and culverts in coastal Georgia, <em>P. destructans</em> presence and burden, and the potential role …

Assessing the impacts of white-nose syndrome induced mortality on the monitoring of a bat community at Fort Drum Military Installation
Since white-nose syndrome (WNS) arrived in the northeastern U.S. in 2006, several affected bat species have exhibited marked population declines (> 90%). For areas such as Fort Drum in northern New York that are subject to regulatory mandates because of the presence of the endangered Indiana bat …
