Estimating Population Numbers Of Black Bears (Ursus Americanus) In Eastern Kentucky Using Microsatellite Analysis, Kelly Vowels Aug 2002

Estimating Population Numbers Of Black Bears (Ursus Americanus) In Eastern Kentucky Using Microsatellite Analysis, Kelly Vowels

Masters Theses & Specialist Projects

Black bears (Ursus americanus) occur sporadically in eastern Kentucky, and there is some evidence that a breeding population exists. In order to establish management practices to enhance the black bear population in Kentucky, information about this population is needed. However, until recently, no population size estimate has been available. Gathering information on black bears is difficult because black bears are elusive animals. The development of new molecular methods has made it easier to track and gather information on black bear populations, including estimates of population size. Molecular markers are particularly useful in that they do not require physical contact with …

Evaluation Of The Persistence Of Grazing Alfalfa Varieties, Maria Stiles May 2002

Evaluation Of The Persistence Of Grazing Alfalfa Varieties, Maria Stiles

Masters Theses & Specialist Projects

The use of alfalfa (Medicago scitiva L.) for grazing is becoming more common. Alfalfa is the most widely planted legume, and is one of the most nutritional forage crops available. It is proposed that alfalfa was cultivated 4000 to 5000 years ago and produces the most protein per acre of any forage crop. Live weight gains for beef cattle grazing alfalfa average 230 to 360 kg ha-1. There is no cheaper way to harvest and utilize alfalfa than for the animal to harvest it directly. Most of the commercially available alfalfa varieties, however, were developed for hay production and thus …

Efficacy Of Sucker Control Method And Effect Of Topping Height On Axillary Bud Growth In Dark Fire-Cured Tobacco, Leslie Thompson Dec 2001

Efficacy Of Sucker Control Method And Effect Of Topping Height On Axillary Bud Growth In Dark Fire-Cured Tobacco, Leslie Thompson

Masters Theses & Specialist Projects

The removal of terminal buds (topping) and sucker control are two practices that have an impact on yield and quality of dark tobacco (Nicotiana tabacum L.). Topping breaks apical dominance and encourages the growth of axillary buds (suckers). Following topping, growth regulator chemicals known as suckercides are commonly used to prevent axillary bud growth. Research has demonstrated that topping time, height, and sucker control method influence the quality and yield of the final product. Delaying topping past a critical developmental stage has been shown to reduce leaf yield. Topping height varies among geographical regions with most dark tobacco producers topping …

Vo2max Comparison Between Seated And Standing Ergometry, Andrew Bosak Aug 2001

Vo2max Comparison Between Seated And Standing Ergometry, Andrew Bosak

Masters Theses & Specialist Projects

Maximum oxygen consumption (VC^max) represents the highest rate at which oxygen can be consumed and utilized to produce energy sustaining aerobic activity. V02max is regarded as the gold standard for assessing aerobic fitness and is essential for prescribing appropriate exercise intensities. Therefore, accurate determination of VC>2max is vital. Usually, VC>2max is obtained when an individual reaches volitional exhaustion during a Graded Exercise Test (GXT). Previous studies show V02max during standing cycle ergometry protocols and treadmill protocols to be similar, while seated cycle ergometry V02tnax values are lower. Conversely, other studies show seated and standing cycle ergometry V02max to …

"Bound Together . . . By Blood And Soul": Donald Davidson's Strategic Retreat Into The Myth Of Life In The Old South, Carol Pigg Dec 2000

"Bound Together . . . By Blood And Soul": Donald Davidson's Strategic Retreat Into The Myth Of Life In The Old South, Carol Pigg

Masters Theses & Specialist Projects

Donald Davidson has often been called stubborn because of his refusal to let go of the Southern past and in his insistence that his writings be based on and in the regional concerns that he saw as fundamental to all Southern literature. In many ways, Davidson's loyalty to the Agrarian and Fugitive causes, which are best defined in these groups interest in keeping the South's history alive and maintaining an agrarian lifestyle, is his greatest contribution to the Southern and American literary canon. Despite this fact, though, Davidson is now, as he was during his lifetime, ignored because of the …

Morphological, Molecular, And Biogeographical Variation Within The Imperiled Virginia Spiraea, Constance Anders Aug 2000

Morphological, Molecular, And Biogeographical Variation Within The Imperiled Virginia Spiraea, Constance Anders

Masters Theses & Specialist Projects

Spiraea virginiana Britton is a rare federally listed rhizomatous shrub endemic to the southern Blue Ridge and Appalachian Plateau physiographic provinces. Populations of S. virginiana are found restricted to scoured sections of high gradient streams within the Ohio River drainage. Present evidence indicates the species is reproducing asexually, most probably through the deposition of rhizomes from upstream populations forming new downstream ramets. Phenotypic variation was examined through a morphometric evaluation of 25 leaf measurements and analyzed using Principal Components Analysis (PCA) and discriminant function analysis. Identity and structure at the molecular level as examined with Randomly Amplified Polymorphic DNA (RAPDs) …
