Modeling Bird Species Occurrence In Current And Future Landscapes, Stephen Nicholas Matthews
Modeling Bird Species Occurrence In Current And Future Landscapes, Stephen Nicholas Matthews
Electronic Theses and Dissertations
With mounting evidence that global temperatures have increased significantly over the last century and the projections of greater changes in climate by the end of this century, understanding the potential consequences of these changes for species is essential to conservation efforts. Here I evaluate the potential response of birds to projected climate change by using regression tree analysis to create models of species distributions under current conditions from Breeding Bird Survey data and then project these models onto General Circulation Model (GCM) scenarios of global climate change. Before modeling species responses to climate change, I selected seventeen bird species to …
Effects Of Small-Gap Timber Harvests On Songbird Community Composition And Site-Fidelity, Mitschka John Hartley
Effects Of Small-Gap Timber Harvests On Songbird Community Composition And Site-Fidelity, Mitschka John Hartley
Electronic Theses and Dissertations
I investigated effects of small-gap timber harvests on bird communities at nine sites (10 ha each) within the Penobscot Experimental Forest (PEF), grouped into three replicated "blocks" (three sites each). Blocks were randomly treated with three treatments: 10% harvest, 20% harvest, and no harvest (i.e., control). I examined how treatments affected breeding songbird abundance, richness, and site-fidelity over four consecutive summers, including 1-3 years before and after each site was harvested. Ability to detect treatment effects was limited by the small number of replicates, but power analyses indicated that given the experimental design and observed variability, there was a high …
Rapid Effects Of 25-Hydroxyvitamin D3 On Calcium Uptake In Isolated Chick Enterocytes, Ruta Phadnis
Rapid Effects Of 25-Hydroxyvitamin D3 On Calcium Uptake In Isolated Chick Enterocytes, Ruta Phadnis
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
25-Hydroxyvitamin D3[25(OH)D3] is a metabolite of vitamin D3 that has long been considered to be an inactive precursor of the hormonally active metabolite 1,25- dihydroxyvitamin D3[l,25(OH)2D3]; consequently very few studies have addressed the potential biological activity of 25(OH)2D3. However, it is known that 100 nM 25(OH)2D3 increases calcium transport in the perfused duodenal loop of the chicken to 200% of controls within 20 minutes. The hypothesis of the current study is that 25(OH)2D3 may be a hormonally active metabolite …
