Attitudes Of South-Central Kentucky Residents Towards Coyotes And Their Management, Andrew T. Mcqueen, Stephen Sumithran Phd

Posters-at-the-Capitol

The existence of the coyote in the eastern U.S. is a recent development and the public’s perception of coyotes has been widely studied in urban areas. However, perceptions in rural areas, especially rural Appalachia, have been largely unstudied. It is necessary for wildlife managers to understand the public’s perceptions of coyotes and coyote management when creating management plans. We conducted a public survey in South-central Kentucky to determine perceptions toward coyotes and coyote management methods. The survey contained questions about demographics (age, gender, county of residence, landownership, etc.), perceptions (fears, opinions), knowledge (true/false questions), and preferred management practices (hunting, trapping, …

Adaptive Plasticity Of Coloration In Response To Environmental Change, Karissa Coffield

Scholars Week

When rapid environmental changes occur, different selective forces can create phenotypic trade-offs in which a trait can provide fitness benefits or costs under different environmental conditions. Amphibians are particularly vulnerable to environmental change, and previous research has revealed that some species will plastically respond to variation in temperature and ultra-violet radiation (UVR) by altering their coloration. Divergent selection on coloration may change with elevation and climate induced shifts in temperature because high temperatures are likely to result in lighter color morphs but as elevation increases, UVR exposure increases leading to the prediction that darker color morphs will be more common. …

Reactive Chlorine Species Reversibly Inhibit Dnab Protein Splicing In Mycobacteria, Daniel Wahl

Scholars Week

Intervening proteins, or inteins, are mobile genetic elements translated within host polypeptides and removed at the protein level by splicing. In protein splicing, a selfmediated reaction removes the intein, leaving only a peptide bond in place. While protein splicing can proceed in the absence of external co-factors, several natural examples of conditional protein splicing (CPS) have emerged. In CPS, the rate and accuracy of splicing is highly-dependent on environmental conditions. As activity of the intein-containing host protein is compromised prior to splicing, and inteins are highly abundant in the microbial world, CPS represents an emerging form of …
