Range-wide assessment of land use and cover change near Indiana bat hibernacula
… Indiana bats (Myotis sodalis) hibernate in 71 hibernacula in the eastern US. Given the species’ 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 …

Investigating biometrics of Perimyotis subflavus in traditional and nontraditional hibernacula in the Southeastern United States as it relates to susceptibility to white-nose syndrome.
… Species Act. Traditionally, bats use caves as hibernacula, but as anthropogenic impacts have increased so has the use of manmade structures like culverts and bridges for roosting by several bat species. The internal environment of these anthropogenic structures is influenced by external …

Head-start Juvenile and Adult Resident Eastern Box Turtles (Terrapene carolina carolina): Winter Ecology Including Microhabitat Selection, Temperature Tolerance and Philopatry
… microhabitat and degree of philopatry to hibernacula for juvenile and adult E. box turtles for two consecutive winters in Charles City Co, VA. The turtles were tracked via radio telemetry to record point locations during the active and inactive seasons. iButton data loggers were attached …

Coloration, Camouflage, and Sexual Dichromatism in the Northern Pacific Rattlesnake (Crotalus oreganus)
… I sampled 127 rattlesnakes from overwintering hibernacula and compared their coloration to that of the surrounding habitat. I also used satellite imagery and land cover classification to investigate possible relationships between snake coloration and habitat at a broader landscape level. The …

Winter Ecology and Ecophysiology of Prairie-Living Big Brown Bats (Eptesicus Fuscus)
… metabolites. Additionally, conditions within hibernacula have a profound influence on hibernation patterns and survival. Periodic arousals and site selection are thought to mitigate these costs, and often involve timing arousals to foraging opportunities and overwintering in locations with …

Effects of Temperature on Winter Energetics of Female Indiana Bats (Myotis Sodalis)
… is increasing cave temperatures in winter hibernacula. Altering cave temperatures can affect torpid bats by raising metabolism and causing more arousals, both of which use more fat reserves. In addition, fluctuations in cave temperatures may cause additional arousals. Unfortunately, no …

Habituation, Scent-Trailing, and Effects of Temperature Upon the Strike-Induced Chemosensory Searching (SICS) in the Cottonmouth (Agkistrodon Piscivorus)
… use conspecific scent trails to locate hibernacula using Y-maze experiments. Neonatal cottonmouths showed no preference for the odors of their mothers, conspecifics, or heterospecifics when paired with a control. This result suggests that neonatal cottonmouths at our study site rely on …

Ambient Temperature Effects on Metabolism and Body Composition in Torpid Bats (Myotis Lucifugus and Pipistrellus Subflavus)
… of M. sodalis has been observed within hibernacula. An increase in cave temperature should result in an increase in metabolic rate during torpor. Without the ability to minimize metabolic needs, irreplaceable energy reserves could become depleted, resulting in death or insufficient …

Spatial Ecology and Habitat Use of the Western Fox Snake (Elaphe Vulpina Vulpina) on Squaw Creek National Wildlife Refuge
… were observed in several male snakes between hibernacula and summer feeding grounds. Females made long migrations (1259 ± 241 SE m) to suspected oviposition sites. Snake home ranges (37.55 ± 8.93 SE ha, 100% MCP) included all tracking points, and snakes traveled at a mean daily speed of 47.39 …

MICROBIAL COMMENSALS OF TRICOLORED BATS IN GEORGIA AND THEIR PROBIOTIC POTENTIAL
… 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 probiotics inoculums have shown success in the management of other recently emerged fungal pathogens of …

Thermoenergetics of Indiana Bats
… of this species have come into focus. As hibernacula temperatures in several caves have increased, the metabolic rate of hibernating bats should increase, resulting in faster utilization of the bats' stored energy reserves; bats use more energy to maintain their torpid state at higher …

Spatial Ecology and Conservation Strategies for the Endangered Northern Long-Eared Bat (<i>Myotis septentrionalis</i>) in a Post-White-Nose Syndrome Landscape
… using passive acoustic surveys associated with hibernacula in western Virginia found that northern long-eared bats were most active near hibernacula during warmer weeks of the fall swarm and spring emergence, when rainfall was low. Similarly, the probability of northern long-eared bat activity …

Spatial Patterns and Multi-Scale Habitat Selection of the Mudsnake (Farancia Abacura) at the Northern Limits of Its Range
… research on the species' nesting behavior and hibernacula selection would be most beneficial to elucidating the species' complete ecological profile.

Population substructuring in Schreibers' long-fingered bat (Miniopterus schreibersii) in South Africa
… schreibersi migrates seasonally between winter (hibernacula) and summer (maternity) colonies in South Africa. Previous behavioural studies suggested that roost fidelity is well developed in this species, and that juvenile dispersal may be limited, possibly in both sexes. If males and/or females …

Prioritization of Carolina Bays as Mitigation Projects from a Herpetofaunal Perspective
… necessary to provide habitat, refuge, and hibernacula for general herpetofauna while meeting regulatory needs. The implications of the research are that it uses existing data and builds upon them to prioritize Carolina bays while still being generalizable to other regions containing …

Evaluating Volatile Organic Compounds for Contact-Independent Antagonism of Pseudogymnoascus destructans and Assessing the Impact of Fungal Pigmentation on Antifungal Susceptibility
… species. The accessibility and ecology of bat hibernacula pose unique complications for application of disease management approaches, contributing to the need for improved application methods of disease treatments. Volatile organic compounds (VOCs) have recently been proposed as a control …

Seasonal activity patterns of bats in the Central Appalachians
… bat species during autumn and spring around hibernacula. Similarly, I set out to determine patterns and drivers of activity for migratory bat species during autumn and spring along mountain ridgelines in the central Appalachians. Lastly, I searched for evidence of potential WNS-induced …

Acoustic sampling considerations for bats in the post-white-nose syndrome landscape
… between WNS impact, influence of available hibernacula, and environmental factors for summer nightly presence of three WNS-affected bats and to compare how multiple models of acoustic detectors perform in terms of detection probability and nightly recorded bat activity. I collected acoustic …

The ecophysiological significance of insectivory as well as nitrogen and phosphorus availability to sundew nutrient cycling, growth, and success
… insect feeding decreased phosphorus retention in hibernacula by 50% (D. rotundifolia). Nutrient additions reduced D. rotundifolia vegetative growth in both N and P addition treatments. In addition, reproductive output (inflorescences) decreased flowering by 98% when N was added to the soil. …
