Modifying The Mineral Profile Of Crickets (Acheta Domesticus) Using A Supplemented Diet, Rhianne Morgan Le Maxwell

Master's Theses and Project Reports

Captive insectivores may consume invertebrates as all, or part of their overall diet. The challenge with feeding captive insectivores involves the limited number of invertebrate species that are commercially available, and the lack of key nutrients provided by these insects. Among these insects, a naturally occurring low concentration of calcium and an inverse calcium to phosphorus ratio may put insectivores at the risk of developing hypocalcemia. A strategy to correct this nutrient imbalance involves supplementing the insect diet with high concentrations of targeted nutrients – a term referred to as gut-loading. Current industry guidelines recommend feeding a supplemented diet for 48 ...

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim ...

The Effect Of Breakfast On Energy Metabolism, Appetite, And Food Intake In Young Versus Older Men, Allie Murphy

Human Nutrition and Hospitality Innovation Undergraduate Honors Theses

As life expectancy continues to rise, it is important to consider optimal nutrition recommendations to improve health outcomes, quality of life, and physical independence in older adults. Previous studies have focused on the impact of breakfast on postprandial appetite in younger adults. Research on the effects of breakfast on appetite in older adults is limited. Several studies have identified protein as a key nutrient for older adults. Protein has been shown to increase satiety for longer periods of time and decrease cravings later in the day when compared to high carbohydrate meals. However, more research is needed to determine the ...

International Journal of Speleology

The activity of enzymes associated with digestion can reflect food availability and feeding preferences of invertebrates in a particular habitat. Caves are mostly nutrient-poor habitats lacking primary production. In the present study the enzymatic activity of cellulases, trehalases and chitinases was measured in eight collembolan species differently associated with the cave environment: the troglobionts (obligate cave species) Pseudacherontides spelaeus and Protaphorura janosik; the eutroglophiles Ceratophysella denticulata, Folsomia candida and Heteromurus nitidus; the subtroglophiles Hypogastrura aequepilosa and Orthonychiurus rectopapillatus; and the trogloxene (not associated with caves) Megaphorura arctica. Qualitative enzymatic patterns and quantitative differences in species activity were considered in terms ...

Breeding For Resistance In California Strawberry To Verticillium Dahliae, Zachary Christman

Theses, Dissertations, and Student Research in Agronomy and Horticulture

Since 1930 the University of California, Davis, has been developing strawberry cultivars that are adapted to the agricultural industry and regional farms. Developing cultivars that require fewer inputs are of significant economic importance in agronomy. Developing a crop resistant to a disease is beneficial for horticulturists since less labor and chemicals are needed for a high yield.⁶

In commercial strawberry cultivars, complete resistance to V. dahlia is extremely rare. The majority of Californian strawberry cultivars are highly susceptible to it.² Over the last 18 years of plant breeding for strawberry cultivars with a high degree of resistance and ...

Obesity, Noah Rhodes

Global Issues in Public Health

Obesity is a worldwide issue that can be defined as a non-communicable condition which means that it is non-infectious and non-transmissible and it is defined as having a BMI over 30 even though BMI doesn’t account for the person’s muscle mass which causes some athletes to be considered obese just because they weigh a lot for their height. Diagnosing obesity can be a long process which includes a health history being taken, a general physical exam, calculation of BMI, and measuring waist circumference. Diagnosis of obesity also involves checking for problems such as high blood pressure, variation of ...
