Morphometric Analysis And Comparisons Of Electrophoretic Protein Profiles Of The Scutellaria Ovata Hill (Lamiaceae) Complex In West Virginia, Virginia And Ohio With Emphasis On Shale Barren Taxa, Eric W. Ewing
Theses, Dissertations and Capstones
Elements of the Scutellaria ovata complex in the eastern United States are reported to include S. ovata var. pseudoarguta, S. ovata var. rugosa, S. ovata var. virginiana and S. ovata ssp. ovata. All but S. ovata ssp. ovata occur in the shale barren habitat of eastern West Virginia and western Virginia. S. ovata var. pseudoarguta has been proposed as a threatened element in North America. A morphometric study of specimens collected in West Virginia, Virginia and Ohio was undertaken to determine which characters are most useful in separating taxa in the complex. Nineteen characters were assessed from 104 herbarium specimens …
Floristics, Plant Community Structure And Bank Profiles, For Five Sites Along The Middle Ohio River, Amy Nicole Morris
Floristics, Plant Community Structure And Bank Profiles, For Five Sites Along The Middle Ohio River, Amy Nicole Morris
Theses, Dissertations and Capstones
Plant community structure, floristics, and bank profiles for five sites along the middle Ohio River were described. Values obtained were compared with a similar study by Clagg and Mills in 1978 on four of the five sites. A total of 186 plant species was observed in the plant community and floristic study. Glenwood Bend had the greatest diversity with 109 plant species. Mason-Pomeroy had the lowest diversity with only 35 plant species. Six species, representing 3.2 percent of the total observed number of species, were present at all five sites. The majority of species, 51 percent, were present at only …
The Effects Of Herbicides On Microbial And Mycorrhizal Populations In Native Prairie, Corn, And Non-Native Prairie Vegetation, Using The Biolog Technique, Susann E. Ahrabi-Fard
The Effects Of Herbicides On Microbial And Mycorrhizal Populations In Native Prairie, Corn, And Non-Native Prairie Vegetation, Using The Biolog Technique, Susann E. Ahrabi-Fard
Dissertations and Theses @ UNI
Soil bioremediation has primarily focused on the use of free living, actively growing microorganisms to degrade toxic organic substances. Recently, however, plants and rhizosphere activity, including mycorrhizal fungi have been increasingly studied to determine the role that consortial assemblages may play in bioremediation. While the enhanced absorbtion of nutrients, water, and minerals by mycorrhizal fungi has been well documented, less is known about their role in the degradation of soil contaminants. Using the Biolog plate technique, microbial communities were characterized in Native Prairie, Corn, and Non-Native Prairie vegetative strips prior to, and after two applications of Acetachlor, Alachlor, and Atrazine. …
