Electronic Theses and Dissertations

The supply of scallops in the United States in recent years has remained relatively stable and the supply source has shifted noticeably from domestic production to imports, especially from China and Japan, where aquaculture production of scallops has been successful. During the past decade, the market share of imported scallops has increased drastically. The scallop fishery in the U.S. is now facing potential competitions from imports. Continuing efforts to provide information on the effect of increasing imports on the U.S. scallop market is warranted.

Public Conservation Land And Economic Growth In The Northern Forest Region, David Lewis

Electronic Theses and Dissertations

Environmental issues frequently revolve around a perceived tradeoff between the economy and the environment. In the Northern Forest region, one of the most important environmental policy issues of recent years has been the ownership of vast stretches of undeveloped forestland. Specifically, the possibility of increasing public conservation ownership on these lands has emerged. Opponents of conservation lands often argue that employment will decline significantly when land is diverted from commodity-oriented uses such as forest products production. Proponents of conservation lands frequently cite the amenity benefits of conservation lands and the potential to diversify and stimulate the economy by designating more …

Trichodesmium Spp.: Numerical Studies Of Resource Competition, Carbohydrate Ballasting, And Remote-Sensing Reflectance, Tonya Denise Clayton

OES Theses and Dissertations

In recent years, a new appreciation for the role of diazotrophy in the oceans has emerged. This dissertation reports on three modeling studies designed to investigate ecological processes associated with Trichodesmium spp., the most conspicuous marine diazotroph: (1) characterization of a generalized model Trichodesmium and issues of macronutrient resource competition; (2) carbohydrate ballasting by Trchodesmium and implications for the formation of surface accumulations; and (3) the vertical distribution of Trichodesmium and implications for detection from space.

Visitor Behaviors And Resource Impacts At Cadillac Mountain, Acadia National Park, Rex Turner

Electronic Theses and Dissertations

The summit of Cadillac Mountain, located in Maine's Acadia National Park, can be reached via three hiking trails and a scenic auto road. This site attracts over an estimated two million visitors per year. Most of this visitation is concentrated from Memorial Day to Labor Day. The sensitive sub-alpine nature of the site, coupled with high visitation rates, has created a scenario where significant vegetation and soil damage occurs. Additionally, Acadia National Park has experienced chronic problems at this site stemming from visitors altering, destroying, or constructing cairns (pyramid shaped piles of rocks built by trail crews to mark trails …

These are to be used as a nutritional supplement in the feeding of children from 6 months of age. Initially, I selected the raw material, due to its high protein content and low cost (soy, tarhui, Cuban corn, rice, wheat, barley). They formed mixes with nutritional characteristics similar to the control for reference (15.5% of protein, 419 kcal of energy). From these formulas, different tests of completed production of mixtures, going so far as to obtain eight mixes with good nutritional and organoleptic …
