Marine primary production can be modeled and estimated using remotely-observable physiological signatures such as chlorophyll and carbon. Current models are based on strict physiological relationships based on photoautotrophic phytoplankton, and discrepancies between modeled and in situ data may stem from unaccounted-for physiological deviations from photoautotrophy. Mixotrophic phytoplankton can obtain energy...
Approximately 900 lines were evaluated, from which 351 lines (337 experimental and 14 named cultivars) were then genotyped. The lines that were retained were planted in the field in 2021 at the Vegetable Research Farm and DNA was extracted from developing leaves. The DNA was quantified, adjusted for concentration and...
This manual gives step-by-step instructions for processing raw data measured by chipod and GusT turbulence sensors. These instruments are designed and manufactured by the Ocean Mixing Group in Oregon State University's College of Earth, Ocean, and Atmospheric Sciences.
Biodiversity loss is of global concern, and is due in part to deforestation and high consumer demand for wood and wood products. The neotropical tree species Cedrela odorata (“Spanish cedar” or “cedro”) is economically valuable for its wood and faces threats of overexploitation. Due to strong similarities in wood features...
The United States is a global leader in agricultural productivity. Much of its productivity growth can be attributed to public investments in agricultural research and development, starting in the 19th century and continuing until today. Past studies have shown high returns to agricultural research investments, but publicly funded agricultural research...
A major challenge to the study of the peopling of the Americas is that much of the Bering Land Bridge (Beringia), the geographic area that people migrating from Northeast Asia into North America would presumably have passed through, is now submerged due to sea-level rise since the last glacial maximum....
Night is an extraordinary resource. Unlike air, water, or soil, nighttime is a spatio-temporal phenomenon, which leads to many crucial roles. It provides refuge to wildlife species, triggers hormonal and behavioral responses among a wide variety of organisms, and serves as an essential migratory backdrop for species that navigate by...
Lifestyle factors are responsible for a considerable portion of cancer incidence worldwide, but credible estimates from the World Health Organization and the International Agency for Research on Cancer (IARC) suggest that the fraction of cancers attributable to toxic environmental exposures is between 7% and 19%. To explore the hypothesis that...
Positive Youth Development (PYD) is both a set of outcomes and a program model that serves to support youth in building healthy relationships with adults and developing the strengths necessary for healthy adulthood. It centers around the 5 C’s of compassion, character, competence, confidence, and connection, which lead to a...
Cultivated plants are often living artifacts that can aid in evaluation of historic or cultural landscapes. However, a working definition for “culturally significant plant” is currently lacking in the guidance literature for the cultural resource management practitioners. Based on a review of the literature on cultivated plants as indicators of...
