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 …
