Importance Of The Microhabitat And Microclimate Conditions In The Northern Gray-Cheeked Salamander (Plethodon Montanus) Across An Elevation Gradient, Trevor Chapman
Electronic Theses and Dissertations
The southern Appalachian Mountains have among the highest salamander diversity in the world, largely due to local speciation in the family Plethodontidae. Plethodontid salamanders (i.e., lungless salamanders) are particularly sensitive to habitat climate conditions due to their reliance on cutaneous respiration, and their immediate environmental conditions (microhabitat) likely influence their dispersion and activity more than the large-scale atmospheric conditions. The Northern Gray-cheeked salamander (Plethodon montanus) is restricted to high elevations in the Appalachian Mountains. Our goal was to investigate the relationship between P. montanus and its microhabitat by examining behavioral preference for climatic conditions, characterizing the microclimate with …
Establishing The Dance Floor: Frame Manipulation Experiments, Peter D. Suich
Establishing The Dance Floor: Frame Manipulation Experiments, Peter D. Suich
Undergraduate Honors Theses
Past studies of honey bee populations, in both natural and laboratory settings have allowed researchers to elucidate the dance language of honey bees within the hive. While the intent and meaning of the waggle dance is thoroughly understood, the area within the hive on which the bees dance is poorly understood. Several factors that may contribute to waggle dancing were studied: substrate, scent and hive entrance proximity. Two separate honey bee colonies were placed in three-frame observation hives. After establishing the dance floor, new experimental conditions were introduced by changing the position of the frames and watching for three days …
