Ontogenetic niche theory predicts that as organisms grow they make size-specific changes in habitat use and diet to optimize growth and survival. A variety of factors contribute to growth and survival in different habitats, ultimately leading to variation in life history that can affect population dynamics. An understanding of the...
Collaborative management of subsistence fisheries in the Philippines requires policies that devolve authority to the local level. This involves creating mechanisms to hold managers accountable for creating opportunities for active participation by fisher folk communities. The Philippines has created a comprehensive national framework for the co-management of coastal resources at...
As reverse transfer students become a larger part of community college enrollments, it is important to better understand the underlying causes of this nontraditional population’s emergence in the traditional community college system. This quantitative descriptive study found that approximately nine percent of the student body enrolled at Rogue Community College...
As more people become interested in rock climbing, the need to understand climbers and their preferences and how their activities impact the resource are more vital than ever. With increased use, and with little empirical data about the Yosemite climbing community, park managers cannot adequately develop a comprehensive climbing management...
Volcanic hazard maps inform the public on the nature and extent of the hazards that threaten them, but these maps are often challenging for those who are not trained in map use or geology. The maps in this study focus on lahars, a dangerous, fast, and far-reaching volcanic hazard that...
Invasive vegetation control studies traditionally aim to control existing populations as well as limit future spread of the species. However, little additional attention has been dedicated to aiding native communities to recover and reestablish. One prominent example of a studied invasive is Brachypodium sylvaticum (Huds.) P. Beauv. (false brome), a...
Drosophila suzukii (Diptera: Drosophilidae), a pest of thin-skinned fruits, has been detected worldwide recently, with new locations of establishment determined annually since it first became a concern on continental North America in 2008. Drosophila suzukii females are different from most other drosophilids as being one of two known species capable...
The United States Congress set out to increase the blending of biofuels by updating and implementing the Renewable Fuel Standard (RFS2) in 2007. The new mandate required that a combination of 36 billion gallons of ethanol, biodiesel, and cellulosic biofuel be blended annually, by 2022. To offset the cost of...
Small manufacturing firms often serve a domestic market but would like to expand their sales overseas. It is difficult for a small firm to develop overseas contracts and relationships, however, in part because of their small size, and because the advantages of their products may not always be obvious. The...
The increasing use of medical procedures using ionizing radiation has increased significantly in recent years. In 1987, the National Council on Radiation Protection Report 93 (NCRP) reported that the average exposure ionizing radiation was 53mRem/year (0.53mSv/year). In their most recent study on radiation exposures NCRP Report 160 in 2009, the...
