This dataset includes skin temperatures of twelve Tadarida brasiliensis held in environmental chambers maintained at 7.7 (SD 0.9) °C and 91.8 (SD 0.8) % relative humidity to induce and support hibernation for up to 3 months. Bats were randomly assigned to infected and control groups at the start of the experiment and infected with conidia of Pseudogymnoascus destructans or a sham treatment (negative control). An iBBat temperature logger (Alpha Mach, Ste-Julie, Quebec, Canada) was attached to the dorsal surface of each bat and programmed to record skin temperature every 15 minutes until the end of the experiment when the bat died or was euthanized.
This work is part of an experimental trial investigating the effects of microclimate conditions of temperature and humidity on a fungal pathogen, Pseudogymnoascus destructans (Pd), that causes white-nose syndrome (WNS) disease in hibernating bats. As part of the trial, tri-colored bats (Perimyotis subflavus) were exposed to Pseudogymnoascus destructans (Pd) and allowed to hibernate in chambers with a variety of temperature and humidity conditions. Bats were euthanized after 83 days. A portion of the wing was rolled around dental wax dowels, fixed in 10% neutral buffered formalin, processed and stained with periodic acid-Schiff, and assessed by light microscopy for evidence of fungal infection. Three types of cutaneous...
1. 1. Badgers, marmots, white-tailed prairie dogs, black-tailed prairie dogs, Wyoming ground squirrels, thirteen-lined ground squirrels and laboratory rats were monitored for their urea hydrolyzing ability by gut bacterial urease during periods of food availability and food deprivation. 2. 2. There did not appear to be a correlation between an animal's ability to hibernate and to expire 14CO2 from hydrolyzed 14C-urea injected intraperitoneally. 3. 3. In addition, fasting and water deprivation (characteristic of hibernation hypothermic bouts) resulted in a decrease in urea hydrolysis by all species except for the rat. It is speculated that urea hydrolysis may be more directly related to gut bacterial biomass or pH...

This data release includes video files and image-processing results used to conduct the analyses of hibernation patterns in groups of bats reported by Hayman et al. (2017), "Long-term video surveillance and automated analyses reveal arousal patterns in groups of hibernating bats.” Thermal-imaging surveillance video cameras were used to observe little brown bats (Myotis lucifugus) in a cave in Virginia and Indiana bats (M. sodalis) in a cave in Indiana during three winters between 2011 and 2014. There are 740 video files used for analysis (‘Analysis videos’), organized into 7 folders by state/site and winter. Total size of the video data set is 14.1 gigabytes. Each video file in this analysis set represents one...
The dataset contains 11 columns of data collected 2017-2018 during a study to assess the ability of invasive Argentine Black and White Tegu (Salvator merianae) to survive in temperate climates of the southeastern USA. Lizards were individually housed in outdoor semi-natural enclosures on the campus of Auburn University in Auburn, Alabama, USA. Database contains tegu identification number, sex, and mean body temperatures as well as environmental temperatures. Temperature data was collected using micro data loggers (iButton Thermochrons) either internally implanted in lizards or placed in lizard enclosures.
1. Arrest temperatures and Q10 values for extensor digitorum longus (EDL), soleus, trabecula, and jejunum muscle twitch strength, contraction time, and 0.5 relaxation time were calculated for a deep torpor hibernator, white-tailed prairie dog (WTPD) (Cynomys leucurus), a shallow torpor hibernator, black-tailed prairie dog (BTPD) (Cynomys ludovicianus), and a non-hibernator, lab rat (Rattus norvegicus) to test the hypothesis that tissue temperature tolerances limit the depth of expressed torpor. 2. There were no temperature tolerance differences between the tissues of the two species of hibernators. Both hibernating species had arrest temperatures and Q10 values more indicative of cold temperature tolerance than...
