Lessons From Chloroviruses: The Complex And Diverse Roles Of Viruses In Food Webs, John Delong, James L. Van Etten, David Dunigan

School of Biological Sciences: Faculty Publications

Viruses can have large effects on the ecological communities in which they occur. Much of this impact comes from the mortality of host cells, which simultaneously alters microbial community composition and causes the release of matter that can be used by other organisms. However, recent studies indicate that viruses may be even more deeply integrated into the functioning of ecological communities than their effect on nutrient cycling suggests. In particular, chloroviruses, which infect chlorella-like green algae that typically occur as endosymbionts, participate in three types of interactions with other species. Chlororviruses (i) can lure ciliates from a distance, using them …

Encouraging Or Guilt-Inducing? An Analysis Of Fitspiration Content And Its Effect On Body Image And Lifestyle Changes, Brenna Mazour

Honors Theses

More people are acquiring their nutrition and exercise information from social media accounts called fitspiration. Analyses of fitspiration content have found the focus to be on restrictive diets and excessive exercise that’s appearance driven. Although its intent is to inspire its consumers to change their lifestyle, many speculate that it brings upon negative body image and induces guilt. The Theory of Planned Behavior (TPB) has been used to determine why people take part in certain health behaviors, such as diets or exercise regimens posted on fitspiration. TPB shows how the characteristics of social media discourage people to use fitspiration as …

Viral Chemotaxis Of Paramecium Bursaria Altered By Algal Endosymbionts, Huy V.N. Ho, David Dunigan, Miranda E. Salsbery, Irina Agarkova, Zeina Al-Ameeli, James L. Van Etten, John Delong

School of Biological Sciences: Faculty Publications

Chemotaxis is widespread across many taxa and often aids resource acquisition or predator avoidance. Species interactions can modify the degree of movement facilitated by chemotaxis. In this study, we investigated the influence of symbionts on Paramecium bursaria’s chemotactic behavior toward chloroviruses. To achieve this, we performed choice experiments using chlorovirus and control candidate attractors (virus stabilization buffer and pond water). We quantified the movement of Paramecia grown with or without algal and viral symbionts toward each attractor. All Paramecia showed some chemotaxis toward viruses, but cells without algae and viruses showed the most movement toward viruses. Thus, the endosymbiotic …

There is a growing number of older adults in the United States, which increases the need for information on how nutrition and aging are interlaced. As humans age, multiple factors can impact nutrition. Nutrition involves consuming the proper amount of nutrients to maintain body function. There are physiological, physical, socioeconomic and medication factors that can all influence nutrition status. It is important to be aware …

Molecular-Assisted Breeding For Soybean With High Oleic/Low Linolenic Acid And Elevated Vitamin E In The Seed Oil, Katherine Hagely, Anji Reddy Konda, Jeong-Hwa Kim, Edgar B. Cahoon, Kristin Bilyeu

Center for Plant Science Innovation: Faculty and Staff Publications

The uses of vegetable oils are determined by functional properties arising from their chemical composition. Soybean oil was previously used in margarines and baked foods after partial hydrogenation to achieve heat and oxidative stability. This process, however, generates trans fats that are now excluded from food use because of cardiovascular health risks. Also present in soybean oil are the anti-oxidant tocopherols, with α- tocopherol (vitamin E) typically present as a minor component compared to γ-tocopherol. Genetic improvement of the fatty acid profile and tocopherol profile is an attractive solution to increase the functional and health qualities of soybean oil. The …
