Winter Snow Depth In Arctic Alaska Results In Complex Changes In Caribou Forage Quality, Jessica C. Richert
Winter Snow Depth In Arctic Alaska Results In Complex Changes In Caribou Forage Quality, Jessica C. Richert
Electronic Theses and Dissertations
Caribou (Rangifer tarandus) rely on the short growing season for much of their annual nutrition, making them susceptible to even small changes in forage quantity and quality. Body condition in the summer and fall is linked to winter survival rates and fecundity in cows, critical factors in the robustness of caribou populations. Due to a warmer, wetter climate, snowfall is predicted to increase over Alaska’s North Slope in the next several decades. Deeper snow results in higher soil temperatures, allowing microbial mineralization of nitrogen to continue throughout the winter and increasing the availability of nitrogen for plants in spring and …
The Efficacy Of Protein Supplementation On Attenuating Muscle Atrophy Following Disuse In The Collegiate Population, Leah Kroeger
The Efficacy Of Protein Supplementation On Attenuating Muscle Atrophy Following Disuse In The Collegiate Population, Leah Kroeger
Electronic Theses and Dissertations
The purpose of this study is to determine the effects of a protein supplementation protocol through a period of muscular disuse in maintaining muscle mass, strength, jump force production, and cross-sectional area in the collegiate population. Two groups of healthy collegiate participants underwent two weeks of unilateral lower limb suspension (ULLS), during which the control group consumed a normal diet and the treatment group received an additional 75 g of protein supplementation. Lean mass, strength, and force production were measured between dietary intakes at baseline and following immobilization. Muscle area was lost between both groups following ULLS (treatment, - 282.8 …
