Foraging And Roosting Behaviors Of Rafinesque's Big-Eared Bat (Corynorhinus Rafinesquii) At The Northern Edge Of The Species Range, Joseph S. Johnson Jan 2012

Foraging And Roosting Behaviors Of Rafinesque's Big-Eared Bat (Corynorhinus Rafinesquii) At The Northern Edge Of The Species Range, Joseph S. Johnson

Theses and Dissertations--Animal and Food Sciences

Bat populations in the eastern United States are currently declining at unprecedented rates as a result of habitat loss, commercial wind energy development, and white-nose syndrome. Effective conservation of these declining populations requires knowledge of several aspects of summer and winter ecology, including daytime habitat use (day-roost selection and social behaviors), nocturnal habitat use (foraging habitat selection, prey selection, and prey abundance), and winter hibernation (torpor) patterns. This dissertation addresses these questions for Rafinesque’s big-eared bat (Corynorhinus rafinesquii), a species of conservation concern in the southeastern United States. Kentucky represents the northern edge of the range of Rafinesque’s …


The Cardiac L-Type Calcium Channel Distal Carboxyl- Terminus Auto-Inhibition Is Regulated By Calcium, Shawn M. Crump Jan 2012

The Cardiac L-Type Calcium Channel Distal Carboxyl- Terminus Auto-Inhibition Is Regulated By Calcium, Shawn M. Crump

Theses and Dissertations--Physiology

The L-type calcium channel (LTCC) provides trigger Ca2+ for sarcoplasmic reticulum Ca2+-release and LTCC function is influenced by interacting proteins including the LTCC Distal Carboxyl-terminus (DCT) and calmodulin. DCT is proteolytically cleaved, and re-associates with the LTCC complex to regulate calcium channel function. DCT reduces LTCC barium current (IBa,L) in reconstituted channel complexes, yet the contribution of DCT to ICa,L in cardiomyocyte systems is unexplored. This study tests the hypothesis that DCT attenuates cardiomyocyte ICa,L. We measured LTCC current and Ca2+ transients with DCT co-expressed in murine cardiomyocytes. We also heterologously co-expressed DCT and CaV1.2 constructs …


Effects Of Self-Directed Physiological Monitoring On Therapists Anxiety, Melissa D. Dalton Jan 2012

Effects Of Self-Directed Physiological Monitoring On Therapists Anxiety, Melissa D. Dalton

Theses and Dissertations--Family Sciences

This mixed-method study investigated the effects of self-directed physiological monitoring on therapists anxiety. Ten therapists participated in a10-week physiological monitoring training sessions while monitoring respiratory sinus arrhythmia (RSA) and heart rate variability (HRV). The participants completed the state-trait anxiety inventory questionnaire after having a first, sixth, or tenth therapy session with a client. This was designed to monitor their state anxiety while working with clients. A series of paired sampled t-tests was conducted to assess changes in HRV, RSA, trait anxiety, and state anxiety. One significant result was found: the RSA of the therapist increased significantly. Correlations existed between …
