During 2016-2018, unprecedented aggregations of the colonial pelagic tunicate Pyrosoma atlanticum were observed in the Northern California Current (NCC). Pyrosomes are common in tropical and sub-tropical ocean waters, but little is known about their abundance, distribution, and trophic ecology in mid-latitude systems. To assess these factors, pyrosomes were collected during...
The purpose of this study was to explore the current levels of physical activity among youth with disabilities using meta-analysis. The search identified 11 publications including 729 participants (age 4-20 yr). The overall effect size for 11 studies was Hedges g = 0.60 (SE = 0.18, 95% confidence interval [CI]...
Butterfly bush (Buddleja davidii), an ornamental native to China, is an invasive species in Oregon and many other areas. In Oregon, butterfly bush invades disturbed areas, particularly riparian areas. The Oregon nursery industry has the highest farm-gate value of all agricultural commodities and butterfly bush is a significant plant to...

The Middle Fork of the John Day River (MFJD) in Northeastern Oregon contains important spawning grounds for spring Chinook and summer steelhead of the Columbia River Basin. In the summer of 2008 phase one of a river restoration project was completed which included the addition of engineered log jams (ELJs)...

This internship project (Dr. Dawn Wright—Department of Geoscience) was a synthesis of several aspects of the research process. The documentation of methods consisted of: primary data collection of soil samples, geographical coordinates, georeferencing, basemap creation, laboratory machine operation, laboratory methods, laboratory quality control planning, statistical analysis, and geo-statistical analysis using...
The OSU Center for Research for Lifelong STEM Learning with support from the OSU Research Office and in collaboration with OSU Outreach and Engagement, convened a “Broader Impacts Invitational Workshop” on December 7, 2012. The workshop solicited opinions and perspectives from 65 participating faculty who were broadly representative of OSU’s...
La présente étude, sur les caractéristiques adaptatives des populations vivant de la pêche artisanale, fut menée au cours de l'été 1994 dans la région lagunaire-estuaire Iguape-Cananéia, située dans le sud-est brésilien. L’auteur démontre que contrairement à une vision statique de la pêche artisanale, ces populations se caractérisent par un forte...
For many historical and contemporary experimental studies in marine biology, seawater carbonate chemistry remains a ghost factor, an uncontrolled, unmeasured, and often dynamic variable affecting experimental organisms or the treatments to which investigators subject them. We highlight how environmental variability, such as seasonal upwelling and biological respiration, drive variation in...
We present an in-depth case study of a learning network that aims to transform infrastructure and practice across the research enterprise to advance societal impacts. The theory of social morphogenesis guides our processual qualitative analysis of the network. We describe how different types of boundary work, both building and navigating...
