Anti-predator behaviors like vigilance or hiding come at the expense of other fitness increasing behaviors such as foraging. To compensate for this trade-off, prey assess predation risk and modify the frequency of anti-predator behaviors according to the likelihood of the threat. In this study, we tested the ability of house...
The purpose of this research was to develop methods for using geographic information system (GIS) analysis and unsupervised classification of Global Vegetation Index (GVI) images to improve carbon budget estimates of the former Soviet Union (FSU). A GIS was used to locate the geographic distribution and estimate the area of...
This project explored one set of tools and procedures that
appeared to have the potential to make the handling of the spatial
data necessary for resource management more efficient and
effective. This project used data from the Nature Conservancy's
Lawrence Memorial Grassland Preserve and was designed to explore
a low...
The end of the Cold War brought about changes within international political relations that resulted in expanded interest in global civil society. Such developments, like globalization and democratization, have encouraged the growth of social and political organizations. Political scientists have found that these inter-governmental and non-governmental organizations have a significant...

Radioisotope Power Systems (RPS’s) are a key element to NASA’s deep space exploration programs. As NASA looks towards new generations of smaller, modular spacecraft, appropriately smaller RPS’s will be needed. The Single General Purpose Heat Source Radioisotope Thermoelectric Generator (S-GPHS-RTG) has been developed to fill this role. The S-GPHS-RTG will...
Characiform fishes form one of the most diverse freshwater fish clades in the world. Comprising more than 2000 species and distributed primarily in South America and Africa, characiforms vary dramatically in their ecomorphology. However, the evolutionary processes responsible for the immense ecomorphological diversity remains unknown. Recently, a study postulated that...
Sexual assault is a major public health concern in the U.S, and college students are particularly vulnerable to victimization. A health issue that affects nearly one in four women (Fisher, Cullen, & Turner, 2000; Karjane, Cullen, & Turner, 2005) and that is associated with severe negative health outcomes, including depression...

Sexual assault is a major public health concern in the U.S, and
The size, shape, and stability of a species’ dietary niche can both influence and reflect a variety of biological patterns, including species interactions, extinction risk, and ecosystem function. This is particularly apparent when dietary changes manifest at ecosystem and clade scales to profoundly affect macroecological and macroevolutionary trajectories. However, many...
Heuristics based on Monte-Carlo Integer Programming (MCIP) and Tabu Search
(TS) techniques were developed for generating easily implementable bucking rules that are
applicable to entire stands (as opposed to individual stem classes), and for selecting the
rule-set that provides the best feasible solution (given log prices and market constraints).
A...
Local governments in Oregon receive money from the
forestry sector in a number of ways. This paper briefly describes
public and private forestry sector sources and the relative
importance of their payments to five forms of local governments
by county for fiscal year 1982-83 to 1985-86. An analysis of the...
