The Gut Microbiome Drives Benzo[a]pyrene's Impact on Zebrafish Behavioral Development

Creator:: Sieler, Michael J.
Abstract:: Benzo[a]pyrene (B[a]P) is a common environmental pollutant produced from the incomplete combustion of organic matter, such as fossil fuel emissions. In vertebrates, B[a]P exposure is associated with hyperactivity, though the underlying mechanisms driving this effect are undescribed. Mounting evidence indicates that the gut microbiome, which is the diverse community of...

Two-phase flow regimes of condensing R-134a at low mass flux in rectangular microchannels

Creator:: Vanderputten, Michael A., Jacob, Tabeel A., Sattar, Maria, Ali, Nouman, and Fronk, Brian M.
Abstract:: Qualitative two-phase flow regime data are obtained from high-speed visualization of condensing flows of R-134a at mass fluxes from 75 to 150 kg m−2 s−1 and quality from 0.1 to 0.8 in square microchannels (DH = 0.84 mm) cooled from a single side. Superheated R-134a is distributed into multiple parallel microchannels and then partially condensed, using...

Assessing the feasibility of a sea otter reintroduction to Oregon through a coupled natural-human lens

Creator:: Curran, Lorne S., Kone, Dominique V., and Wickizer, Benjamin J.
Abstract:: Sea otters fulfill a keystone role in several Northeastern Pacific nearshore ecosystems. However, their influence has been absent in Oregon coastal waters since their extirpation in the 19th and early 20th century. Interest has been growing for a translocation attempt to reintroduce sea otters to Oregon from one or more...

Seeing the Ocean For the Whales: How Whales Get Lost in the Sea of Human Perceptions

Creator:: McKinnon, Haley
Abstract:: Humans have always been fascinated with whales; from prominent features in mythology, to stories of terrifying monsters on the high seas, to globalized utility, to symbolic wildness and radical environmentalism, to figures and statistics, how have human relationships with whales been understood throughout time? Because humans have a need to...

The influence of sea ice and snow cover and nutrient availability on the formation of massive under-ice phytoplankton blooms in the Chukchi Sea

Creator:: Zhang, Jinlun, Ashjian, Carin, Campbell, Robert, Spitz, Yvette H., Steele, Michael, and Hill, Victoria
Abstract:: A coupled biophysical model is used to examine the impact of changes in sea ice and snow cover and nutrient availability on the formation of massive under-ice phytoplankton blooms (MUPBs) in the Chukchi Sea of the Arctic Ocean over the period 1988–2013. The model is able to reproduce the basic...

Phytochemical, antioxidant and antibacterial potential of Elaeagnus kologa (Schlecht.) leaf

Creator:: Merculieff, Zoe, Ramnath, Shubharani, Sankoli, Seethalakshini Madhukar, Venkataramegowda, Sivaram, Murthy, Ganti S., and Ceballos, Ruben Michael
Abstract:: Objective: To screen different solvent extracts of Elaeagnus kologa (E. kologa) leaf to determine the phytochemicals, potent antioxidant and antibacterial activity to find out the possible source of applied pharmaceutical formulations. Methods: Solvent extracts of leaf material were prepared using the Soxhlet apparatus. A study was performed on antioxidant activity...

eDNA as a tool for identifying freshwater species in sustainable forestry: A critical review and potential future applications

Creator:: Coble, Ashley A., Flinders, Camille A., Homyack, Jessica A., Penaluna, Brooke E., Cronn, Richard C., and Weitemier, Kevin
Abstract:: Environmental DNA (eDNA) is an emerging biological monitoring tool that can aid in assessing the effects of forestry and forest manufacturing activities on biota. Monitoring taxa across broad spatial and temporal scales is necessary to ensure forest management and forest manufacturing activities meet their environmental goals of maintaining biodiversity. Our...

Response of Conifer-Encroached Shrublands in the Great Basin to Prescribed Fire and Mechanical Treatments

Creator:: Miller, Richard F., Ratchford, Jaime, Roundy, Bruce A., Tausch, Robin J., Hulet, April, and Chambers, Jeanne
Abstract:: In response to the recent expansion of piñon and juniper woodlands into sagebrush-steppe communities in the northern Great Basin region, numerous conifer-removal projects have been implemented, primarily to release understory vegetation at sites having a wide range of environmental conditions. Responses to these treatments have varied from successful restoration of...

The silence of the clams: Forestry registered pesticides as multiple stressors on soft-shell clams

Creator:: Tissot, Alexandra G., Granek, Elise F., Thompson, Anne W., Hladik, Michelle L., Moran, Patrick W., and Scully-Engelmeyer, Kaegan
Abstract:: Contaminants are ubiquitous in the environment, often reaching aquatic systems. Combinations of forestry use pesticides have been detected in both water and aquatic organism tissue samples in coastal systems. Yet, most toxicological studies focus on the effects of these pesticides individually, at high doses, and over acute time periods, which,...

Genetic and morphological evidence suggests cryptic speciation within the Torrent Sculpin, Cottus rhotheus, across the Pacific Northwest

Creator:: Nicholas, Benjamin P.
Abstract:: Dwelling on the bottom of large rivers to high alpine streams, freshwater sculpins (genus Cottus) occur in high densities across the Pacific Northwest, with 21 currently recognized species found in the Pacific Northwest. Sculpin fill many ecological roles, with some species serving as important prey sources, and others competing with...
