Underwater: Science & Story In Aquatic Communities, Lena J. Beck

Graduate Student Theses, Dissertations, & Professional Papers

How do we manage fish species, and how do fish, in turn, impact us? This portfolio of three stories will explore some of the ways in which humans interact with aquatic landscapes. First, we’ll go to Flathead Lake in Montana, where invasive lake trout have all but decimated native trout species, and learn what the Confederated Salish and Kootenai Tribes are doing to address the issue. Then, we’ll examine stories of a legendary Big Fish in Alaska’s Lake Iliamna, and think about what it means to scientifically prove something as real. The last story looks at the aquaculture industry in …

Getting To The Root Cause: The Genetic Underpinnings Of Root System Architecture And Rhizodeposition In Sorghum, Farren Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Plants are some of the most diverse organisms on earth, consisting of more than 350,000 different species. To understand the underlying processes that contributed to plant diversification, it is fundamental to identify the genetic and genomic components that facilitated various adaptations over evolutionary history. Most studies to date have focused on the underlying controls of above-ground traits such as grain and vegetation; however, little is known about the “hidden half” of plants. Root systems comprise half of the total plant structure and provide vital functions such as anchorage, resource acquisition, and storage of energy reserves. The execution of these key …

Articles

Peppers of the Capsicum genus have a rich nutritional composition and are widely consumed worldwide. Thus, they find numerous applications in the food, pharmaceutical and cosmetic industries. One commercial application is oleoresin production, a nonpolar fraction rich in bioactive compounds, including capsaicinoids and carotenoids. Among the technologies for pepper processing, special attention is given to supercritical fluid technologies, such as supercritical fluid extraction (SFE) with pure solvents and CO2 plus modifiers, and SFE assisted by ultrasound. Supercritical fluid-based processes present advantages over the classical extraction techniques like using less solvents, short extraction times, specificity and scalability. In this review, we …
