A new checklist of the macrobenthic marine algae of Oregon is presented. The new list includes 50 new records and 90 new names, providing an overall nomenclatural change in the recorded flora of 36 percent since the earlier list of Phinney (1977). Of the 387 taxa reported, 20 percent have...
Dairy Creek, located in Washington County, Oregon, has a drainage area of approximately 230 square miles, and includes West Fork, East Fork, and McKay Creek drainages. Dairy Creek is a major tributary of the Tualatin River which experiences algal problems during the late summer when stream flows decrease and water...
A cinematographic analysis of hurdling technique was completed
using six high school women in the 100 meter hurdle event as
subjects. The study was descriptive in design, intending to make
objective comparisons of selected elements of the hurdling action.
Sixteen hypotheses were developed and tested, in an effort to describe...
Global environmental change is causing local extinctions of species. When species depend on one another, as in the mutualistic relationship between plants and pollinators, loss of one interaction partner may cause cascading effects within the community – such as additional extinctions and reduced pollination services. Network theory provides a way...
Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...
The myxozoan parasite Ceratonova shasta threatens both juvenile and adult salmonid populations in the Pacific Northwest region of the United States, causing intestine necrosis and hemorrhaging, along with high mortality in some fish strains. It induces an inflammatory tissue response in susceptible strains of fish; understanding the interactions between C....
Emerging research shows that individual differences in how people use technology sometimes cluster by socioeconomic status (SES) and that when technology is not socioeconomically inclusive, low-SES individuals may abandon it. To understand how to improve technology’s SES-inclusivity, we present a multi-phase case study on SocioEconomicMag (SESMag), an emerging inspection method...
