Life History Variation Of Common Terns In The Gulf Of Maine, Jeffery Bryant Kimmons

Graduate Theses and Dissertations

Life history is the inheritable rules that determine energy and time allocation towards different competing functions in the energy budget of an organism. Reproductive effort varies as organisms make reproductive decisions based on available energy. Factors influencing life histories are those that change energy and time budgets such as diet, competition, and environmental conditions.

Common tern (Sterna hirundo) life history phenotypes vary between islands in the Gulf of Maine. Common terns on offshore islands (>10km from mainland) and nearshore islands (5 to 10km from mainland) lay smaller clutches, hatching chicks with slower growth rates than common terns …

Effects Of Associated Subcortical Beetles On Oviposition Behavior And Early-Stage Survival Of Sirex Nigricornis F. (Hymenoptera: Siricidae), Ace J. Lynn-Miller

Graduate Theses and Dissertations

Sirex (Hymenoptera: Siricidae) woodwasps develop within xylem of host conifers. Sirex females drill through the bark, phloem and into xylem tissues where they deposit eggs along with a symbiotic Amylostereum fungus. The presence of Amylostereum is necessary for successful development of Sirex immatures as the larvae are unable to derive adequate nutrition from xylem in the absence of the fungus. The Eurasian woodwasp, Sirex noctilio F., was discovered in northeastern North America in 2004. Sirex noctilio has caused significant economic damage in Pinus radiata D. Don plantations of the southern hemisphere, but is of little economic significance in its native …

Journal of Food Law & Policy

National concerns, such as obesity, should be addressed through national efforts. Considering the national reach of the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) and the Supplemental Nutrition Assistance Program (SNAP) and their ability to influence the diets of a significant amount of the nation's population, changes to these programs should be made to encourage healthy nutrition.

Food Sovereignty In The United States: Supporting Local And Regional Food Systems, Allison Condra

Journal of Food Law & Policy

Today, perhaps more than ever, an increasing portion of U.S. society is paying attention to and asking questions about our food and agricultural system. We are recognizing the immense consequences of the agricultural "efficiencies" we valued and wrote into our policies in the seventies-for example, growing corn "fence row to fence row" and the ease of microwaved meals and prepackaged foods. 3 The increasingly global nature of our food system and its consequences are becoming more apparent. Food safety concerns-prompted by a growing number of foodborne illness outbreaks and the government's response in the 2009 Food Safety Modernization Act-loom large …

The Real Toy Story: The San Francisco Board Of Supervisors Healthy Food Incentives Ordinance, Cortney Price

Journal of Food Law & Policy

Obesity among children in the United States has tripled over the last thirty years. Incidentally, the world's largest fast food restaurant, McDonald's, first introduced its children's Happy Meal thirty-two years ago. Shortly thereafter, the first Disney inspired toy found its way into Happy Meals and the hearts of the "billions and billions served." Although the iconic Happy Meal and accompanying toy have become "a staple of Americana akin to baseball and apple pie," the continued existence of the practice is being threatened in light of the powerful influence toys have on children's food choices, thus contributing to the current obesity …

Cash, Crops, Chemicals, And Cosmetics: A Mid-Green Eco-Labeling Approach, Michael T. Olexa, R. Benjamin Lingle, Kimberly Stewart, Damian C. Adams

Journal of Food Law & Policy

The United States Department of Agriculture (USDA) uses grade standards to uniformly characterize the quality and condition of agricultural commodities. The standards are promulgated by the USDA's Agricultural Marketing Services (AMS) division in consultation with farming industry groups. Emphasizing produce attributes such as surface defects, shape, cleanliness, color, maturity, and decay, grade standards improve the marketability of agricultural commodities by establishing a common industry language for use in contracts. Use of such a language enables wholesale buyers to know the quality of commodities without first having to inspect them, thus facilitating trade by lowering transaction costs.

Population Dynamics In Predynastic Upper Egypt: Paleodemography Of Cemetery Hk43 At Hierakonpolis, Ernest King Batey Iii

Graduate Theses and Dissertations

The site of Hierakonpolis is considered to have played an important role in the development of the Egyptian state, which formed at end of the fourth millennium BC. Archaeological evidence suggests that, for the Middle and Late Predynastic periods (ca. 3900-3200 BC), Hierakonpolis may be characterized as having experienced the following: a growth in both settlement and population size, an increased reliance on cereal agriculture, development of craft specialization, and the presence of a Social hierarchy as interpreted from an observed increase in the differentiation of mortuary behavior. Historical data suggest that these Social and economic changes would have affected …

Characterization And Epidemiology Of Soybean Vein Necrosis Associated Virus, Jing Zhou

Evaluation Of The Recombination Efficiencies Of Flp Proteins, Linh Duy Nguyen

Graduate Theses and Dissertations

Site-specific recombination systems are powerful tools for genetic modification. They have been used to integrate a transgene into a pre-defined locus and to remove marker genes from a transgene locus. Two of the most widely used site-specific recombination systems in plants are the Cre/lox system from the bacteriophage P1 and the FLP/FRT system from the yeast Saccharomyces cerevisiae. The Cre/lox system is well-characterized and is the first choice in application of site-specific recombination system. However, some applications such as marker-free site-specific gene integration require the use of two recombination systems. In addition, the availability of alternative recombination systems can offer …

Community Structure And Ecological Specialization In Plant-Ant Interactions, Paola Barriga

Graduate Theses and Dissertations

Positive associations among species have contributed to the maintenance of biodiversity. These interactions are typically studied in pairwise fashion where two interacting organisms are the focus. This dissertation uses network theory to analyze positive plant-ant associations in three Neotropical forests. Obligate plant-ant mutualisms were used, where plants host the ants in domatia and provide food bodies while the ants protect the plants and can feed them. A network approach was used to depict all obligate plant-ant interactions within a community. The main questions asked at the community level were: 1) Do network structure and levels of specialization change geographically and, …

Effects Of Felled Shortleaf Pine (Pinus Echinata Mill.) Moisture Loss On Oviposition Preferences And Survival Of Sirex Nigricornis F. (Hymenoptera: Siricidae), Jessica Hartshorn

Graduate Theses and Dissertations

The European woodwasp, Sirex noctilio F. (Hymenoptera: Siricidae) utilizes pine as its host during larval development. Females drill through pine bark to deposit eggs, a symbiotic fungus, Amylostereum, and phytotoxic mucus into the tree. In their native range, these insects are not viewed as primary pests because they attack dead or dying trees. Over the last century, this woodwasp has been accidentally introduced into several countries in the southern hemisphere. Some regions have incurred millions of dollars in damage to large plantations of the widely planted pine species, radiata pine (Pinus radiata D. Don). Sirex noctilio was discovered …

Influence Of Nutritional Modifications On Sow, Litter, And Nursery Performance, Benjamin Edward Bass

Graduate Theses and Dissertations

Two separate series of experiments were conducted to determine: 1) the influence of dietary arginine supplementation in late gestation on reproductive performance, and 2) the impact of a whole yeast product in gestation, lactation, and weaned pig diets on reproductive, growth, and immune parameters.

In the first study 99 sows were provided a control diet, or the control diet supplemented with 1% L-arginine from gestation d 93 to 110. Compared to control-fed sows, no differences were observed in reproductive parameters, however a tendency for increased gestational weight gain was observed for sows provided supplemental arginine.

In a second study, 98 …

The Impact Of Bovine Spongiform Encephalopathy (Bse) On World Protein Supply, Jarrod Kersey

Graduate Theses and Dissertations

As world population, per capita income and urbanization increase, consumption of meat, poultry, milk and eggs will continue to rise to meet the needs of approximately nine billion people in 2050. Global beef, pig and chicken production and per capita consumption increased between 2000 and 2010, with growth in broiler production and consumption outpacing both beef and swine. The increased production and consumption requires readily available feed ingredients in regions where animal production is rapidly developing. Animal-based protein feed ingredients are often difficult to move from country to country due to real or perceived risk of animal disease. Zoosanitary standards …
