Ubiquitin Dependent Proteolysis In The Frozen Wood Frog, Michael Ulrich, Ken Storey, Frank Van Breukelen
Ubiquitin Dependent Proteolysis In The Frozen Wood Frog, Michael Ulrich, Ken Storey, Frank Van Breukelen
Undergraduate Research Opportunities Program (UROP)
Wood frogs (Rana sylvatica) freeze during the winter. One might presume that homeostatic processes like protein synthesis and degradation cease during freezing. However, few data are available. In collaboration with Dr. Ken Storey (Carelton University, Canada), we are investigating the primary mode of proteolysis in wood frogs representing different points of the freeze-thaw cycle.
The Effects Of The Ground Reaction Force On The Muscle-Tendon Systems About Guinea Pig Joints, Theresa Schill, Kevin Mailland, David V. Lee
The Effects Of The Ground Reaction Force On The Muscle-Tendon Systems About Guinea Pig Joints, Theresa Schill, Kevin Mailland, David V. Lee
Undergraduate Research Opportunities Program (UROP)
Each limb of the limb joints of a quadruped is used differently during locomotion, and it is necessary to recognize the mechanical role each plays. The effects of the ground reaction force on the ankle, knee, and hip joints of Hartley albino guinea pigs were studied in uphill, downhill, and level situations to determine the spring-like capacity of the muscle-tendon systems that act about the limb joints.

Impact Of Historical Climate Change On The Genetic Structure Of The Great Basin Pocket Mouse, Perognathus Parvus, Ashwitha Francis, Mallory E. Eckstut, Brett R. Riddle
Undergraduate Research Opportunities Program (UROP)
The dynamics of genetic patterns, such as genetic differentiation within and between populations and the geographic distribution of genetic lineages, are often influenced by historical events (such as climatic changes) that have substantially impacted regional biodiversity (the study of phylogeography; Avise, 20001). The magnitude of genetic differentiation among populations is often increased if suitable habitat is reduced, because there is restricted migration among populations. When migration is restricted, the populations may become genetically differentiated from conspecific populations and, over time, may become independent lineages that follow distinctive evolutionary trajectories (Stebbins, 19523; Nevo & Beiles, 19892; Thomas et al., 19984). In …
3d Micro-Mr And Micro-Ct Models For Determining In-Vivo Function In The Guinea Pig Knee Model Of Osteoarthritis (Oa), Kristoffer W. Dean
3d Micro-Mr And Micro-Ct Models For Determining In-Vivo Function In The Guinea Pig Knee Model Of Osteoarthritis (Oa), Kristoffer W. Dean
Undergraduate Research Opportunities Program (UROP)
Osteoarthritis (OA) is a debilitating disease that affects an estimated 27 million adults in the United States. OA causes damage to cartilage in the joints resulting in bones that rub together. This creates pain, swelling, loss of motion of the joint, and bone spurs. As the number of adults above 65 grows (an estimated 72 million people by 2030) even more people will be at high risk for OA. It is the most common type of arthritis by far yet very little is known about it including relationships between joint structure and function. In 2004, the NIH created the Osteoarthritis …
Influence Of Weaning Strategy On Animal Welfare In Beef Calves, Lindsey B. Krebs
Influence Of Weaning Strategy On Animal Welfare In Beef Calves, Lindsey B. Krebs
Undergraduate Research Conference
Alternative strategies can affect the amount of stress that calves encounter at weaning. The strategies being evaluated in this study are fenceline, two-stage, and traditional abrupt. Fenceline weaning involves placing the calves in a pasture adjacent to their cows so they can have contact with each other through the fence. Two-stage weaning utilizes anti-suckling devices that clip into the calves noses and prevent them from suckling their cows. The calves remain with the cows for a short amount of time, then they are weaned and separated from their cows. This allows the stressors of weaning to be faced in two …
Role Of Clover "Down On The Farm", Don Sorrell
Role Of Clover "Down On The Farm", Don Sorrell
Forage Symposium at the Kentucky Cattlemen’s Convention
In an effort to evaluate the Role of Clover ”Down on the Farm”, a survey was developed and then e-mailed to Agriculture and Natural Resources Extension Agents in Kentucky. Agents were asked to complete the survey based on their estimate of use and importance of clover in their particular county. Thirtytwo (32) surveys were returned. The following is a summary of those returned surveys.
Establishing Clovers In Pasture And Hay Fields, Garry D. Lacefield
Establishing Clovers In Pasture And Hay Fields, Garry D. Lacefield
Forage Symposium at the Kentucky Cattlemen’s Convention
Pasture renovation means to renew and improve. In Kentucky, this usually means adding lime and fertilizer, controlling weeds and insects and planting a legume such as red clover and/or white clover. The primary benefits come as a result of getting legumes established in grass-dominated fields.
Estimating Clover Percentage In Your Pasture, S. Ray Smith
Estimating Clover Percentage In Your Pasture, S. Ray Smith
Forage Symposium at the Kentucky Cattlemen’s Convention
You often hear Extension Agents and Extension Specialists talk about how important it is to add clover to your grass pastures. We talk about the advantage of free nitrogen, the added forage quality and yield, the benefit of diluting the toxic effects of tall fescue, and many other benefits. Usually after I give a presentation promoting all the benefits of clover the first question from the audience is, “How much clover do I need?” My standard answer is that 30 to 40% clover provides many of these benefits without compromising grass productivity. In fact, 30 to 40% clover in a …
Why Grow Clovers?, Don Ball, Garry D. Lacefield
Why Grow Clovers?, Don Ball, Garry D. Lacefield
Forage Symposium at the Kentucky Cattlemen’s Convention
Clovers have long been viewed as being special and beneficial pasture plants, but recently the incentives livestock producers have to grow them have further increased. Why are many people more interested than ever in growing clovers in pastures as companion species with grasses? Here are several reasons that collectively make a compelling case.
