Economic Impacts of Hypoxia on North Carolina Brown Shrimp

Creator:: Huang, Ling, Nichols, Lauren A. B., Craig, J. Kevin, and Smith, Martin D.
Abstract:: While environmental stressors such as hypoxia (low dissolved oxygen) are perceived as a threat to the productivity of coastal ecosystems, policy makers have little information about the economic consequences for fisheries. Prior studies based on data aggregated at relatively large spatial (e.g.,1000s km) and temporal (e.g., annual) scales have typically...

Effects of atrazine on olfactory-mediated behaviors in Pacific lamprey (Entosphenus tridentatus)

Creator:: Smith, April G.
Abstract:: Pacific lamprey (Entosphenus tridentatus) are experiencing population declines throughout their range. Xenobiotics could be an important risk factor for lamprey populations. Our goal was to establish if common herbicides, as used in forest management, could affect reproductive fitness. We determined that atrazine was a likely compound of greatest concern to...

The Effects of Nitrate and a Pathogenic Fungus, Batrachochytrium dendrobatidis, on Amphibians

Creator:: Negru, Delia
Abstract:: The current rate of global biodiversity loss and extinctions is unparalleled and a major concern. Freshwater organisms are facing particularly rapid rates of biodiversity loss. Amphibians, which require an aquatic environment for part of their life cycle, are one of the most vulnerable vertebrate groups. Amphibians are experiencing population declines,...

Improvements in the dosimetric models of selected benthic organisms

Creator:: Caffrey, Emily Amanda
Abstract:: The International Commission on Radiological Protection (ICRP) has modeled twelve reference animal and plant (RAP) species using simple geometric shapes in Monte–Carlo (MCNP) based simulations. The focus has now shifted to creating voxel phantoms of each RAP to advance the understanding of radiation interactions in nonhuman biota. The work contained...

The effects of environmental stressors on cardiac gene expression and contractility in rainbow trout (Oncorhynchus mykiss)

Creator:: Momoda, Tracey S.
Abstract:: Rainbow trout (Oncorhynchus mykiss) experience a variety of stressors in their natural environment as well as in aquaculture that can have negative effects on their physiology. The effects of physiological stress and endocrine disruption have been well described in fish. However, there is a scarcity of information on the effects...

Photo-enhanced Toxicity of Oil Constituents and Corexit 9500 to Gulf of Mexico Marine Organisms

Creator:: Finch, Bryson E.
Abstract:: Significant inputs of hydrocarbons are continually released into the environment from anthropogenic and natural sources. Some of the most toxic hydrocarbon compounds are polycyclic aromatic hydrocarbons. Polycyclic aromatic hydrocarbons are known for their ability to absorb ultraviolet light and enhance toxicity. Generally, PAHs exert their toxicity via narcosis but UV-absorbing...

Experimental and numerical modeling of wave height attenuation by emergent coastal vegetation

Creator:: Blackmar, Philip James
Abstract:: Coastal vegetation dampens waves which can provide benefits to the local area, but existing literature shows large variations in the degree of wave height attenuation depending on plant properties and wave conditions. Better knowledge of how to predict the wave height decay accurately in different types of vegetation may help...

The Responses of Slope-spawning Flatfish to Environmental Variability in the Eastern Bering Sea

Creator:: Vestfals, Cathleen D.
Abstract:: When adult spawning and juvenile settling locations of marine fishes are geographically separated, their early life history stages must rely on transport and their own behavior to move them toward suitable habitats for successful recruitment to the juvenile phase. Variations in climate may reduce the availability of spawning and juvenile...

Evaluating benthic macroinvertebrates as bio-indicators of freshwater habitat quality in an eastern Oregon agro-ecosystem

Creator:: Scherr, Melissa A.
Abstract:: The effect of anthropogenic disturbance on river systems is gaining attention, and concerns about the state of freshwater natural resources are increasing globally, as are efforts to restore habitat that has been degraded by disturbance. In rivers, non-point source pollution affects the physical characteristics of the habitat and the endemic...

Addressing the future of water in Oregon : a look at the human and institutional factors shaping Oregon water management

Creator:: Wolters, Erika Allen
Abstract:: Oregon is a state with great social and ecological diversity. Unfortunately however, Oregon's water-rich reputation is more rumor than reality. As with many Western states, Oregon struggles with water scarcity, especially during dry summer months. Recent efforts by the state to develop an integrated water resource strategy (IWRS) to manage...
