We sought to determine 1) the relationship between seedling
establishment rates of target native prairie species and field
levels of three soil nutrients (phosphate, nitrate, and ammonium)
recorded in fall, winter, and summer, 2) the effect of fire on
these three nutrients, and 3) the overall effect of fire on...
Competition between ‘Pinot noir’ grapevines and alleyway cover crops
was evaluated in two commercial vineyards in western Oregon. Seven
cover crop treatments including a clean-cultivated control were applied
in the fall of 2003 and their impact on vines was monitored in 2004
and 2005. Competition with grapevines was assessed by...

To determine if diet affects the growth rate of juvenile ling cod, we began with three initial objectives: 1) Record the growth rates of juvenile lingcod on different diets (squid and sardine); 2) Determine if hemocyanin will cause lingcod skin and muscle pigmentation will take on a...
Cancer is class of diseases that has great diversity and unfortunately is one of the leading causes of death in the United States. Chemotherapy remains an important cancer treatment modality, and superior chemotherapeutic drugs are constantly being sought. Gemcitabine is an anti-tumor chemotherapeutic drug and it is the first line...
Teaching assessment can be a pain. But it can also be an opportunity. This poster describes my experience with student course evaluations and the development of a supplemental assessment tool.
I teach two courses required for the college’s general education curriculum: Western Civilization and the Environment, and Natural Resources in...
Restoration projects that involve revegetation efforts are often confronted with problems of desiccation. Several studies have shown that mulching, or laying organic material over the surface of the soil, can be very effective in helping to retain soil moisture and avoid desiccation. To determine the effects of moisture retention in...
Self-regulated learners are students who take an active role in their education and have the desire to become more competent and more capable as learners (Zimmerman, 1990). Teaching student skills to be more self-regulated has been shown to help students improve their thinking and organizational skills (Pape, Bell, & Yetkin,...
Small mammal populations are vital to the Metolius Forest Preserve. The forest preserve is undergoing selective thinning, which may affect small mammal populations in the forest. Our null hypothesis is that small mammal populations are not affected by the treatment of the forest. In addition to the null hypothesis, we...
Road decommissioning will be a valuable science in the future of ecological restoration because of the excess number of roads in this country. May things like habitat fragmentation, erosion, spread of invasive species, and access to fragile environments can be linked to roads. For this study I selected a road...
The purpose of this study was to see if fifth grade students agreed with the research that says that children can easily and rapidly identify social isolation within their peer groups (Dodge, Coie, Pettit, Price, & Joseph, 1990 ).
Restoration ecology seeks to incorporate entire ecosystem functioning; primarily attempting to repair what has been degraded or altered. In order to reinstate ecological processes, biotic and abiotic components must be included, such as flora, fauna, hydrology, and of course, soil. Soil provides many functions in which all aspects of life...
Thinning of overstory timber will change forest function and productivity of understory vegetation. Increased solar exposure promotes understory growth, and disturbance caused by thinning will create an opportunity for species establishment. We set up a study to collect baseline data on the understory community at the Metolius Preserve. Our data...
There are two objectives of this experiment. The first is to test the effectiveness of various soil treatments on cheatgrass (Bromus tectorum) canopy cover. The second is to compare the two treatment types side by side to evaluate their relative effectiveness in treating cheatgrass. The treatments we selected are easily...
It is time to open up the dialogue about old age with a healthy and positive outlook. The current state of Oregon is faced with high elder suicide rates and depression is common with elders. I propose a complex including the following: • A focus on the mind and body...
Human land use practices have degraded hundreds of thousands of miles of water corridors in the U.S. Fortunately, there has been an increase in effort to restore many of these aquatic habitats. Currently, the Deschutes Basis Land Trust (DBLT) is proposing to reconnect a portion of Whychus creek that flows...
The sustainable landscape model we are creating is an attempt to visually make community members aware of the water issue in our region. This xeric landscape will be aesthetically pleasing as well as functional, to represent the suitability for residential function. Water consumption is an issue in the West, typically...
This study compares arthropod biodiversity in areas infested with invasive cheatgrass Bromus tectorum with areas not infested. The goal of this project was to establish a baseline of the types of arthropods found in both habitats, discover if there is more diversity in either habitat and to find any patterns...
The roles of today’s grandparents have drastically changed from fifty years ago. Grandparents are now expected to give up their retirement and that “grandparent relationship” to fill in the position of “parent” when the child’s parents can no longer do so. This can be a hardship for both the grandparents...
The social impact of the Red Hat Society is twofold: first, the “disorganization” is grounded solely in the belief that women over 50 have too long been ignored by society…hence the outrageous hats, boas and colors that accompany a Red Hat outing (Cooper, 2004). The sheer number of “Red Hatters”...
