Monitoring Mammals At Multiple Scales: Case Studies From Carnivore Communities, 2021 University of Massachusetts Amherst
Monitoring Mammals At Multiple Scales: Case Studies From Carnivore Communities, Kadambari Devarajan
Carnivores are distributed widely and threatened by habitat loss, poaching, climate change, and disease. They are considered integral to ecosystem function through their direct and indirect interactions with species at different trophic levels. Given the importance of carnivores, it is of high conservation priority to understand the processes driving carnivore assemblages in different systems. It is thus essential to determine the abiotic and biotic drivers of carnivore community composition at different spatial scales and address the following questions: (i) What factors influence carnivore community composition and diversity? (ii) How do the factors influencing carnivore communities vary across spatial and temporal ...

Thin Safety Margin: The Sefor Super-Prompt-Critical Transient Experiments, Ozark Mountains, Arkansas 1970–1971, Jerry Havens, Collis Geren
Arkansas Scholarly Editions
Thin Safety Margin charts the history of SEFOR, a twenty-megawatt reactor that operated for three years in the rural Ozark Mountains of Arkansas as part of an internationally sponsored program designed to demonstrate the Doppler effect in plutonium-oxide-fueled fast reactors. Authors Jerry Havens and Collis Geren draw upon this history to assess the accidental explosion risk inherent in using fast reactors to reduce the energy industry’s carbon dioxide emissions.
If a sufficiently powerful fast-neutron explosion were to cause the containment of a reactor such as SEFOR’s to fail, the reactor’s radiotoxic plutonium fuel could vaporize and escape ...

Wildflower Pollen Quality In Roadside Habitats, With Particular Emphasis On Hedera Helix, Aoife Mcmullin, Paul Hamilton
SURE_J: Science Undergraduate Research Journal
The quality of air is of more significance today than ever before. Human population growth and pollutants emitted through fossil fuel consumption put pressures on air quality. It is widely acknowledged that atmospheric pollutants negatively impact human health; the same is also true for the health of wildlife and plants exposed to these pollutants (Brunekreef & Holgate, 2002; EEA, 2019; Schiavoni, et al., 2017). Pollen and seed formation of flowering plants have been affected when grown in areas of poor air quality (Azzazy, 2016; Sénéchal, et al., 2015). The purpose of this research was to assess pollen of Hedera helix (ivy), a native ...

Do Environmental Toxins Predict Violent Crimes?, 2021 Kennesaw State University
Do Environmental Toxins Predict Violent Crimes?, Tyler Stahl
Symposium of Student Scholars
Do chemical pollutants that persistent in the environment and bioaccumulate in the body affect human health and behavior? Could these Persistent, Bioaccumulative, and Toxic (PBT) chemicals play a role in the cause of violent crimes due to deterioration of mental and cognitive functions? In the past, Mercury, a PBT chemical, has been shown in salmon to be associated with aggression. Could similar aggression occur in humans exposed to mercury through a toxic spill? Two sources of data are utilized in this analysis. The Environmental Protection Agency’s (EPA) Annual Toxic Release Inventory publishes data on toxic releases into the environment ...
Recurrent Pattern Of Extreme Fire Weather In California, 2021 Gwangju Institute of Science and Technology
Recurrent Pattern Of Extreme Fire Weather In California, Rackhun Son, S-Y Simon Wang, Seung Hee Kim, Hyungjun Kim, Jee-Hoon Jeong, Jin-Ho Yoon
Mathematics, Physics, and Computer Science Faculty Articles and Research
Historical wildfire events in California have shown a tendency to occur every five to seven years with a rapidly increasing tendency in recent decades. This oscillation is evident in multiple historical climate records, some more than a century long, and appears to be continuing. Analysis shows that this 5–7 year oscillation is linked to a sequence of anomalous large-scale climate patterns with an eastward propagation in both the ocean and atmosphere. While warmer temperature emerges from the northern central Pacific to the west coast of California, La Niña pattern develops simultaneously, implying that the lifecycle of the El Niño-Southern ...
Unintended Consequences Of Air Cleaning Chemistry, 2021 Bucknell University
Unintended Consequences Of Air Cleaning Chemistry, Douglas B. Collins, Delphine K. Farmer
Faculty Journal Articles
Amplified interest in maintaining clean indoor air associated with the airborne transmission risks of SARS-CoV-2 have led to an expansion in the market for commercially available air cleaning systems. While the optimal way to mitigate indoor air pollutants or contaminants is to control (remove) the source, air cleaners are a tool for use when absolute source control is not possible. Interventions for indoor air quality management include physical removal of pollutants through ventilation or collection on filters and sorbent materials, along with chemically reactive processes that transform pollutants or seek to deactivate biological entities. This perspective intends to highlight the ...

Spatial Analysis Of Landscape Characteristics, Anthropogenic Factors, And Seasonality Effects On Water Quality In Portland, Oregon, Katherine Gelsey, Daniel Ramirez
REU Final Reports
Urban areas often struggle with deteriorated water quality as a result of complex interactions between landscape factors such as land cover, use, and management as well as climatic variables such as weather, precipitation, and atmospheric conditions. Green stormwater infrastructure (GSI) has been introduced as a strategy to reintroduce pre-development hydrological conditions in cities, but questions remain as to how GSI interacts with other landscape factors to affect water quality. We conducted a statistical analysis of six relevant water quality indicators in 131 water quality stations in four watersheds around Portland, Oregon using data from 2015 to 2021. Indiscriminate of station ...
Current State Of Seagrasses In Zanzibar: Impacts Of Coastal Economic Activities And Marine Protected Areas On Seagrass Cover, 2021 School for International Training Graduate Institute
Current State Of Seagrasses In Zanzibar: Impacts Of Coastal Economic Activities And Marine Protected Areas On Seagrass Cover, Danielle Purvis, Narriman Jiddawi
Seagrass meadows are located abundantly in Zanzibar, Tanzania and provide essential ecosystem services, such as sediment nutrient enrichment and blue carbon sequestration. However, seagrasses have been less researched or protected than other marine ecosystems. Although environmental variables affect seagrass health, evidence suggests that anthropogenic impacts are their greatest threats. The rapid expansion of seaweed farming and tourism and widespread use of harmful small-scale fishing practices in Zanzibar have contributed to the degradation and removal of seagrass meadows, disrupted coastal marine food chains, and reduced local biodiversity that seagrasses support. Public or private marine protected areas (MPAs) protect most of Zanzibar ...

Spatial Variability Of Nonpoint Source Yields In Ozark Highlands Watersheds Under Historical And Recent Land Use Conditions, Tyler J. Pursley
MSU Graduate Theses
Many of the environmental problems facing communities today stem from historical as well as present land use disturbances related to agriculture, urbanization, and resource extraction. It is important to evaluate a range of land use and soil effects on nonpoint source (NPS) pollution to fully understand land use-water quality relationships. The Ozark Highlands region has undergone significant phases of land use change throughout its settlement history and is actively developing today (2020). This study used nonpoint nitrogen (TN), phosphorus (TP), and sediment (TSS) yields predicted by the US EPA’s Spreadsheet Tool for Estimating Pollutant Loads (STEPL) model to evaluate ...
Marine Debris And Human Health: An Exposure Pathway Of Pops?, 2021 Portland State University
Marine Debris And Human Health: An Exposure Pathway Of Pops?, Katie Conlon
Urban Studies and Planning Faculty Publications and Presentations
Although there are not any direct studies linking persistent organic pollutants (POPs) accumulated on marine debris to human health, there are numerous studies showing human health impacts from repeated and high level POP exposure, as well as studies that show POPs accumulate on plastic debris in the marine environment. With this knowledge, there is a need for greater awareness of the risks of POP exposure for those who handle marine debris regularly, especially in contexts of higher exposure such as those working in marine debris concentrated areas. Amongst the scientific community, understanding of the exposure risk might be high, but ...
