The chemolithoautotrophic nitrite oxidizing bacteria (NOB) participate in the
biogeochemical cycling of nitrogen by catalyzing and conserving energy from the
oxidation of nitrite (NO₂-) to nitrate (NO₃-) via a nitrite oxidoreductase (NXR). The
main objective of this work was to comparatively annotate and analyze the genome
sequences of Nitrobacter winogradskyi...
Nitrobacter hamburgensis X14 is a facultative lithoautotroph that conserves energy from the
oxidation of nitrite (NO
2 ) and fixes carbon dioxide (CO2) as its sole source of carbon. The
availability of the N. hamburgensis X14 genome sequence initiated a re-examination of its
mixotrophic and organotrophic potential, as genes encoding...
In this study I discuss the state of Free-Choice Learning research, and an investigation into the use of personal ubiquitous technology on visitors' experiences at a science center. The three manuscripts included in this document:
1. Review published research on free-choice learning from 1997-2007 from selected journals
2. Examine visitors'...
European hazelnut, an important nut crop in Oregon agriculture, is threatened by the fungal disease eastern filbert blight (EFB) caused by Anisogramma anomala (Peck) E. Müller. The hazelnut breeding program at OSU has been working on development of EFB-resistant cultivars. DNA markers allow mapping of traits using segregating progenies and...
Microplastics, plastic marine debris less than 5 mm in size, is a threat to the health of our oceans. One important way to reduce microplastics in our oceans is to educate people about the issue, particularly future decision-makers. In this study, a middle school curriculum was developed using current scientific...
Zoos and aquariums are among the best informal education avenues for individuals to further develop conservation beliefs and values. Research documented the presence of conservation messages at aquariums, that visitors expect such messages, and staff and volunteers at conservation organizations increase their conservation-related knowledge and behaviors. This research often focuses...
Science is one of the fundamental building blocks of modern societies, and though some science topics are easily accepted by public audiences, others generate intense social controversy by challenging beliefs that are fundamental to a person’s, or group’s, identity. The Theory of Evolution is one of these “hot-button” issues, as...
The environmental movement needs people from communities of color and the differing perspectives they provide. Latinas/os are one of the largest communities of color in the US, and their numbers continue to grow. However, mainstream environmental organizations have failed to engage this community in authentic ways. The lack of meaningful...

Abstract
The environmental movement needs people from communities of color and
Due to the overwhelming concern for the current state of our oceans, The Pew Ocean Commission (2003) and the U.S. Commission on Ocean policy (2004), have both strongly recommended an increase in our society’s ocean literacy. An increase in ocean literacy can be achieved through informal education institutions such as...
With over 175 million Americans visiting each year and the ability to create unique learning experiences, informal science institutions may play a greater role in climate change education in the coming years. As facilities in Oregon begin to incorporate climate science and solutions into their educational programming, effective communication across...
