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,...

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...

Evaluating the size and extent of paleolakes in central Tibet during the late Pleistocene

Creator:: Shi, Xuhua, Furlong, Kevin P., Kirby, Eric, Meng, Kai, Marrero, Shasta, Gosse, John, Wang, Erchie, and Phillips, Fred
Abstract:: Subhorizontal lake shorelines allow a geodynamic test of the size and extent of a hypothesized paleolake in central Tibet, the East Qiangtang Lake (EQL), during the last interglacial period (marine isotope stage (MIS) 5e). Reconstructions based on relict lake deposits suggest that the EQL would have been ~400 m deep...

Reconciling Conflicting Phylogenies in the Origin of Sweet Potato and Dispersal to Polynesia

Creator:: Muñoz-Rodríguez, Pablo, Carruthers, Tom, Wood, John R.I., Williams, Bethany R.M., Weitemier, Kevin, Kronmiller, Brent, Ellis, David, Anglin, Noelle L., Longway, Lucas, Harris, Stephen A., Rausher, Mark D., Kelly, Steven, Liston, Aaron, and Scotland, Robert W.
Abstract:: The sweet potato is one of the world’s most widely consumed crops, yet its evolutionary history is poorly understood. In this paper, we present a comprehensive phylogenetic study of all species closely related to the sweet potato and address several questions pertaining to the sweet potato that remained unanswered. 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 Viability of Container-Based Sanitation as a Tool for Sanitation Coverage in Urban Haiti

Creator:: VanRiper, Froggi Ramona
Abstract:: Haiti is far from achieving the UN goal of sanitation access for all; 20% Haitians have no sanitation access, and less than 0.1% of urban excreta is safely managed. Container-Based Sanitation (CBS) may be a key tool for achieving equitable sanitation coverage in Haiti’s cities. CBS is a sanitation strategy...

Potential effects of sea-level rise on plant productivity: species-specific responses in northeast Pacific tidal marshes

Creator:: Janousek, Christopher
Abstract:: Coastal wetland plants are adapted to varying degrees of inundation. However, functional relationships between inundation and productivity are poorly characterized for most species. Determining species-specific tolerances to inundation is necessary to evaluate sea-level rise (SLR) effects on future marsh plant community composition, quantify organic matter inputs to marsh accretion, and...

Vertical Ground Reaction Force During the Forward Lunge and Squat for Dominant and Non-Dominant Limbs in Older Adults

Creator:: Thompson, Ronald D.
Abstract:: Falls in older adults are a significant issue in the United States. Many older adults are advised to participate in fall prevention exercise programs in an attempt to increase strength and stability, but it is unclear what role limb dominance and potential limb asymmetry has in exercise performance. The purpose...

Exploring the distribution of waterborne pathogens Giardia and Cryptosporidium along a land-use gradient in Oregon in the context of One Health

Creator:: Aleman Torres, Mariangel
Abstract:: Giardia and Cryptosporidium protozoans are resilient, zoonotic waterborne pathogens that can bypass water treatment and kill millions of people and animals annually. Giardia and Cryptosporidium cysts and oocysts, respectively, can spread through feces; poor sanitation and poverty can increase the risk for giardiasis and cryptosporidiosis diarrheal diseases. We are currently...

Metabolomics analysis identifies effects of nitrate and exercise in zebrafish (Danio rerio)

Creator:: Wolfe, Mandy
Abstract:: Objectives: Nitrate, found abundantly in green leafy vegetables, may improve exercise performance by increasing the availability and utilization of metabolic fuels that require less oxygen for energy production. However, it is not known if this performance effect occurs at the peak exercise intensity. We hypothesize that supplemental nitrate treatment will...
