The influence of carbon dioxide and pH on the dissolved oxygen requirements of some fresh-water fish

Creator:: McNeil, William John
Resource Type:: Masters Thesis

Effects of Elevated CO₂ on Speckled Sanddab (Citharichthys stigmaeus) Behavior

Creator:: Andrade, Jessica F.
Abstract:: The direct and indirect effects of ocean acidification (OA) are a growing concern, particularly in areas already experiencing elevated levels of oceanic CO₂. Studies with marine fishes suggest that elevated CO₂ levels may affect behavior by interfering with an important brain neurotransmitter. Studies examining the effects of OA fish behavior...

Impacts of Ocean Acidification on Coralline Algae : From Species to Community Consequences

Creator:: Shen, Chenchen
Abstract:: Oceanic uptake of rising anthropogenic CO₂ emissions has caused the emergence of ocean acidification as a major threat to marine ecosystems worldwide. Along eastern boundary current systems, seawater is naturally acidified due to coastal upwelling of low pH seawater from depth. Compounded by ocean acidification, upwelling regions are expected to...

Growth and physiological responses of Sitanion hystrix, Artemisia tridentata ssp. wyomingensis, and Stipa thurberiana to elevated CO₂ : interactions with soil temperature and water stress

Creator:: Lucash, Melissa S.
Abstract:: Since plants utilize CO₂ as the substrate for photosynthesis, terrestrial plants may be directly affected by increasing levels of CO₂ in the atmosphere. Plants native to the sagebrush steppe are predicted to increase in growth in response to elevated CO₂ through increased water use efficiency and higher photosynthetic rates. This...

A study on the effects of enhanced pCO2 on open ocean diazotrophic assemblages

Creator:: Gradoville, Mary Rose
Abstract:: Biological di-nitrogen (N₂) fixation is a key process in open-ocean ecosystems, where the new nitrogen (N) provided by marine diazotrophs can support a large fraction of primary productivity and carbon (C) drawdown. Recent laboratory studies have shown that elevated pCO₂ enhances the rate of N₂ fixation by select laboratory isolates...

Insights from stable isotope dynamics into the sensitivity of larval Pacific oysters to ocean acidification

Creator:: Brunner, Elizabeth Lev
Abstract:: Larvae of the Pacific Oyster, Crassostrea gigas, at Whiskey Creek Shellfish Hatchery (WCH) in Netarts Bay, Oregon, are negatively impacted by high-CO₂ water and exposure during the initial shell formation period appears to be particularly damaging. To investigate the mechanism of this early susceptibility, several cohorts of larvae at WCH...

Comparison of radiative feedback variability over multiple time scales in climate model and reanalysis data

Creator:: Dalton, Meghan M.
Abstract:: In a steady state, the Earth's absorbed solar radiation (ASR) balances the outgoing longwave radiation (OLR) at the top of the atmosphere (TOA). In response to a radiative forcing, that is, an external perturbation to the top of the atmosphere energy balance, the Earth's climate system adjusts until reaching a...

Changing Climate, Changing Contexts : Variation in Rocky Intertidal Predator-prey Interactions Seen Through an Environmental Stress Framework

Creator:: Cerny-Chipman, Elizabeth B.
Abstract:: The multifaceted role of the environment in regulating the structure and dynamics of biological communities has long fascinated ecologists and motivated much debate and research. Now, in a time of accelerated global changes due to human impacts, the need to understand how the environment shapes communities has gained new urgency....

Seagrasses as Potential Chemical Refugia for Acidification-Sensitive Bivalves

Creator:: Smith, Stephanie Rae
Abstract:: As the effect of ocean acidification (OA) on marine calcifiers is better understood, a range of potential mitigative strategies have been proposed, many of which are plagued by concerns of scale and feasibility. One oft-cited option is to increase the biomass of photosynthetic organisms to remove CO₂ from the water...
