Biological introductions may considerably alter the composition and community dynamics of invaded areas thereby changing many ecosystem processes including productivity, decomposition, nutrient cycling and hydrology. The effects on native species may be obscured by a lack of information on distribution and abundance patterns. The Japanese eelgrass, Zostera japonica, was introduced...
This study was commissioned and funded by the Coastal Oregon Marine Experiment Station (COMES) to 1) identify the scientific and management issues constraining the advancement of the Oregon bay clam commercial industry, 2) explore scientific, management, and economic opportunities for the enhancement of the fishery, 3) outline and suggest mechanisms...
A five year longitudinal study was begun in 1976 to find a
solution to the problem of early primary children who fail in school
and then adopt the failure syndrome. The study was conducted in four
elementary schools in Oregon which had distinctly different
socio-economic populations.
The tests used for...
Lingcod (Ophiodon elongatus) are known to utilize certain estuaries along the Pacific coast of the United States, but the importance of these habitats to the coast-wide population is not well understood. In this study, general patterns of estuarine habitat use were assessed by tracking the movement of sub-adult and adult...
Consideration of social and cultural dimensions in coastal and marine planning has increased and ecosystem services provide important framing to investigate values and priorities associated with these systems. Research efforts in coastal communities offer insights on social dimensions of ocean and coastal management decisions, but questions remain about how demographics...
The Common Core State Standards for Mathematical Practice (SMPs) describe ways of thinking and doing mathematics that parallels how mathematicians engage with mathematics (National Governors Association for Best Practices, 2010). These standards reflect a broader goal in K-12 mathematics education focused on moving beyond K-12 learners acquiring knowledge of mathematical...
Secure Computation is a powerful tool that enables a set of parties to jointly compute any function over their private inputs, without a trusted third party. Private Set Intersection is a specific case of two-party Secure Computation, where Alice (with private set X) and Bob (with private set Y) specifically...
In this study, biological and chemical characteristics were determined for two high-elevation meadow-to-forest transitions located in the Central Oregon Cascades. The chloroform fumigation incubation method (CFIM) was used to determine microbial biomass C(MBC) and the N flush due to fumigation (NF), and meadow values were compared to forest values for...
Patterns of nest attendance behavior by breeding birds represent a parent-offspring trade-off in which adults balance self-maintenance with parental care decisions.
Incubation, in particular, is of interest because adults must provide an environment
suitable for embryonic development through nest-building and contact-incubation.
We evaluated how adult incubation constancy and nest visitation...
