Ethylene Production As An Indicator Of Stress Conditions In Hydroponically-Grown Strawberries, Justin Donald Hogan
Ethylene Production As An Indicator Of Stress Conditions In Hydroponically-Grown Strawberries, Justin Donald Hogan
Theses, Dissertations and Capstones
With the worldwide phaseout of methyl bromide, the use of hydroponic systems has increased as an economic alternative for the growth of many horticulturally-important crops, including strawberries. In this study, the effect of hydroponics on strawberry plant physiology was examined by first measuring ethylene levels, a plant hormone known to increase due to stressful conditions, and plant growth and yield. Using a gas chromatograph, ethylene was measured from plants which showed that light and temperature have minimal effects, but placement of plants could have an effect on plant growth and yield. Next, the mechanism of ethylene production was examined by …
Terrestrial Habitat Use Of Marbled Salamanders Ambystoma Opacum: A Site Specific Approach, Frank Piccininni
Terrestrial Habitat Use Of Marbled Salamanders Ambystoma Opacum: A Site Specific Approach, Frank Piccininni
Theses, Dissertations and Capstones
Habitat destruction, fragmentation and degradation have contributed heavily to the decline of amphibian populations such as Marbled Salamanders (Ambystoma opacum). Often, ambystomatid water resources are conserved without consideration for the equally important terrestrial habitat. This is partly due to a lack of information regarding the relationship between ecological succession, plant community composition, microhabitat and salamander abundance. Three sampling transects consisting of drift fence arrays, vegetation assessments and microhabitat surveys were extended 100 m into the terrestrial habitat surrounding a seasonal wetland at Beech Fork State Park in Wayne County, West Virginia. Principal components analysis was used to identify …
A Taxonomic Study Of The Genus Acris And The Status Of Acris Crepitans Blanchardi (Harper), Blanchard's Cricket Frog, In Southern Ohio And Western West Virginia, Amy M. Hamilton
Theses, Dissertations and Capstones
Distributions of Acris crepitans and Acris gryllus cover most of the eastern United States with some overlap, and the subspecies Acris crepitans blanchardi and Acris crepitans crepitans also occur sympathric in parts of their ranges. My study analyzed 15 morphological characteristics of A. c. blanchardi, A. c. crepitans, and A. g. gryllus using Canonical Discriminate Analysis. Results support current taxonomy, showing the most separation between A. crepitans and A. gryllus and some overlap between A. c. blanchardi and A. c. crepitans. Sexual dimorphism was seen only in A. c. blanchardi and A. c. crepitans with females being larger …
