Phytoplankton and microzooplankton comprise the base and the first link of the marine food web, respectively. These microbes are key drivers of marine carbon and nutrient cycles. Phytoplankton convert atmospheric CO₂ into organic carbon, and microzooplankton consume phytoplankton, packaging phytoplankton carbon into particulate forms that have a variety of fates:...
Many studies suggest that weedy plant species are most successful when
soil nitrogen in abundant. Consequently, I used soil nitrogen manipulations to
determine if altering nitrogen would affect the establishment of both weedy and
native plant species in a western Oregon wetland prairie. In two studies, we
added carbon amendments...
The bioavailability of chemical compounds in the marine environment fundamentally influences the growth and physiology of microorganisms. Organic and inorganic chemicals that are produced by some marine plankton can be consumed by other plankton for energy production, growth, or to initiate essential physiological processes. Cultures of the diatom Thalassiosira pseudonana,...
Diatoms play a major role in ocean biogeochemical cycles and are important tools in bioengineering for natural products and nanotechnology. Diatoms and other algae growing at varying resource-limited growth rates allocate carbon to different metabolic pathways to optimize growth; however, the molecular mechanisms controlling these pathway gating strategies are not...
Photosynthetic energy allocation strategies were investigated in the marine diatom, Thalassiosira pseudonana, grown under a wide range of light limitation. Steady-state, continuous cultures were established at three light-limited growth rates. Simultaneous measurements of photosynthetic activity were made that targeted different points in photosynthetic energy flow from gross to net photosynthesis....

The researcher explored interpersonal trust (a construct from the fields of psychology
and sociometry) in the context of engineering work groups. The study explored the potential
antecedents of trust and the relationships among trust, creativity, communication, emotional
empathy and positive affect. The study attempts to argue that 1) trust is...
Synechococcus is one of the most abundant groups of primary producers in the marine environment. They play a crucial role in the food web by being the main source of alimentary energy to many marine organisms that contribute to human nutriments. The ability of Synechococcus to use light as a...
This paper offers a brief reflection on my personal journey and development as I embark as a paraprofessional into the world of higher education, focusing on my growth as a practitioner, learner, scholar, leader, and human. I will share formative experiences that contributed to my development and discuss my process...
We compiled Western Pond Turtle (Actinemys marmorata) and Painted Turtle (Chrysemys picta) locations in northwestern North America, consolidating data from multiple sources including nine U.S. State and Canadian Provincial jurisdictions. We assessed numbers of discrete locations, and analyzed distribution patterns temporally and spatially. Western Pond Turtle observation records ranged from...
