Nurse Rock Microclimates Significantly Buffer Exposure To Freezing T Temperature And Moderate Summer Temperature, Joshua L. Conver, Elliott Yarwood, Lucas D. Hetherington, Don E. Swann

United States National Park Service: Publications

Nurse tree canopies mitigate exposure to freezing temperatures that could result in injury or mortality to the saguaro cactus (Carnegiea gigantea). Abiotic objects have been hypothesized to provide similar beneficial microclimates. We used data loggers at 11 nurse rock sites to record daily daytime summer maximum and winter nighttime minimum temperatures at Saguaro National Park, Arizona, to examine the effectiveness of rocks to moderate seasonal temperature extremes in the microclimate. Temperatures at rock sites averaged 2 °C warmer than exposed open control sites in winter. We found that the efficiency of rocks to act as insulators significantly increased as temperature …

Beryllium-7 Elucidate Sediment Dynamics Of The Branford River Estuary, Connecticut, Usa, Gaboury Benoit, Matthew Hirschbeck, Beth Bisson

United States National Park Service: Publications

Berrylium-7 elucidates sediment dynamics (i.e., sources, sinks, deposition, and resuspension) in a Connecticut estuary. Average 7 −2−1 annual atmospheric deposition of Be is 290 mBq cm year. Sediment samples from 43 locations within the estuary show that 7Be deposition is spatially complex, but were statistically indistinguishable a year apart. Weekly time series of sediments indicate 7 that levels are nearly constant on this shorter time scale on ceradio active decay is taken into account. Be levels in sediments area balance between steady losses through radioactive decay and periodic pulse inputs following rainstorms. The water column was measured intensively during three …

Implications Of Organic Mass To Carbon Ratios Increasing Over Time In The Rural United States, W.C. Malm, B.A. Schichtel, J.L. Hand, A.J. Prenni

United States National Park Service: Publications

The thermal evolution procedure used by most monitoring programs in the United States to determine carbonaceous aerosol concentrations is referred to as the thermal‐optical reflectance method, where an aerosol sample that has been collected on a quartz filter is heated and evolved carbon is characterized as either organic (OC) or light absorbing carbon (LAC). Evolved carbon assigned to OC is multiplied by a factor, Roc, to achieve an estimate of organic mass. Over the last 10–15 years, Roc, estimated through multiple linear regression analysis of data collected in the Interagency Monitoring of Protected Visual Environments (IMPROVE) program, has increased at …

Berry Important? Wolf Provisions Pups With Berries In Northern Minnesota, Austin T. Homkes, Thomas D. Gable, Steve K. Windles, Joseph K. Bump

United States National Park Service: Publications

Wolves (Canis lupus) primarily provision pups by catching mammalian prey and bringing remains of the carcass to the pups at a den or rendezvous site via their mouths or stomach. In August 2017, we observed an adult wolf regurgitating wild blueberries (Vaccinium spp.) to pups at a rendezvous site in the Greater Voyageurs Ecosystem, Minnesota, USA, which is the only known observation of wolves provisioning pups with wild berries. This observation, in combination with other evidence from the Greater Voyageurs Ecosystem, suggests wild berries might be a more valuable food source for wolves in southern boreal ecosystems than previously appreciated.

Modelling Pinniped Abundance And Distribution By Combining Counts At T Terrestrial Sites And In-Water Sightings, Steven L. Whitlock, Jamie N. Womble, James T. Peterson

United States National Park Service: Publications

Pinnipeds are commonly monitored using aerial photographic surveys at land- or ice-based sites, where animals come ashore for resting, pupping, molting, and to avoid predators. Although these counts form the basis for monitoring population change over time, they do not provide information regarding where animals occur in the water, which is often of management and conservation interest. In this study, we developed a hierarchical model that links counts of pinnipeds at terrestrial sites to sightings-at-sea and estimates abundance, spatial distribution, and the proportion of time spent on land (attendance probability). The structure of the model also allows for the inclusion …

Dental Microwear As A Behavioral Proxy For Distinguishing Between Canids At The Upper Paleolithic (Gravettian) Site Of Predmostí, Czech Republic, Kari A. Prassack, Josephine Dubois, Martina Laznickova-Galetova, Mietje Germonpre, Peter S. Ungar

United States National Park Service: Publications

Morphological and genetic evidence put dog domestication during the Paleolithic, sometime between 40,000 and 15,000 years ago, with identification of the earliest dogs debated. We predict that these earliest dogs (referred to herein as protodogs), while potentially difficult to distinguish morphologically from wolves, experienced behavioral shifts, including changes in diet. Specifically, protodogs may have consumed more bone and other less desirable scraps within human settlement areas. Here we apply Dental Microwear Texture Analysis (DMTA) to canids from the Gravettian site of P�redmostí (approx. 28,500 BP), which were previously assigned to the Paleolithic dog or Pleistocene wolf morphotypes. We test whether …

Bird Community Monitoring At Tallgrass Prairie National Preserve, Kansas, Status Report 2001–2018, David G. Peitz, Kathleen A. Kull

United States National Park Service: Publications

Executive Summary

In 2001, the Heartland I&M Network initiated breeding bird surveys on Tallgrass Prairie National Preserve, Kansas, to assess the ecological integrity of the preserve’s habitat. Birds are an important component of ecosystems and can serve as good indicators of habitat change in an ecosystem. In the 17 years of bird surveys at the preserve (2001 to 2018, excluding 2003), there were 2,089 plot visits and 119 different bird species recorded, 96 of which have the potential to breed within the preserve. These 96 species represent approximately 81% of the total species one would reasonably expect to have breeding …

Measuring Spatial And Temporal Shifts In Forest Structure And Composition In T High Elevation Beech Forests In Response To Beech Bark Disease In Great Smoky Mountains National Park, Lee Rubmle, Glenn Taylor, Joshua B. Grinath, Ashley B. Morris

United States National Park Service: Publications

Exotic forest pests and pathogens are among the most serious environmental threats to millions of hectares of forested land worldwide. Beech Bark Disease (BBD) is a non-native, pathogenic complex consisting of associations between scale insects and fungi. First confirmed in Great Smoky Mountains National Park (GRSM) in 1986, this complex has since threatened local high elevation beech forests, which are G-1 ranked (critically imperiled) forest communities where American beech (Fagus grandifolia Ehrh.) is a foundational tree species. In 1994, GRSM initiated the BBD Monitoring Protocol at 10 high elevation beech forest plots in the Park. The plots were sampled biennially …

Prey Of Reintroduced Fishers And Their Habitat Relationships In The Cascades T Range, Washington, Mitchell A. Parsons, Jeffrey C. Lewis, Jonathan N. Pauli, Tara Chestnut, Jason I. Ransom, David O. Werntz, Laura R. Prugh

United States National Park Service: Publications

Conservation and recovery of forest carnivores requires an understanding of their habitat requirements, as well as requirements of their prey. In much of the western United States, trapping and habitat loss led to extirpations of fishers (Pekania pennanti) by the mid-20th century, and reintroductions are ongoing to restore fishers to portions of their former range. Fisher recovery in Washington State has been limited by isolation from other populations, but other potentially important factors, such as diet of fishers in this region and prey availability, have not been thoroughly investigated. We collected hair samples from potential prey and fishers for stable …

Following The Newark, Nj Drinking Water Lead Crisis, Morgan Clauser

Gettysburg Social Sciences Review

In the summer of 2018, after it was revealed that there were dangerous levels of lead in the drinking water in Newark, New Jersey, the Natural Resources Defense Council and the New Jersey Education Workers Caucus filed a lawsuit against the City of Newark. They claimed the city did not comply with statues in the Safe Drinking Water Act, Lead and Copper Rule, and New Jersey’s Open Public Records Act. This case follows the nationally recognized case in Flint, MI, and both cases present undertones of systemic racism through the inaction of local governments. While the jury is still out …

The Effects Of Historical Housing Policies On Resident Exposure To Intra-Urban Heat: A Study Of 108 Us Urban Areas, Jeremy Hoffman, Vivek Shandas, Nicholas Pendleton

Urban Studies and Planning Faculty Publications and Presentations

The increasing intensity, duration, and frequency of heat waves due to human-caused climate change puts historically underserved populations in a heightened state of precarity, as studies observe that vulnerable communities—especially those within urban areas in the United States—are disproportionately exposed to extreme heat. Lacking, however, are insights into fundamental questions about the role of historical housing policies in cauterizing current exposure to climate inequities like intra-urban heat. Here, we explore the relationship between “redlining”, or the historical practice of refusing home loans or insurance to whole neighborhoods based on a racially motivated perception of safety for investment, with present-day summertime …

Plains Zebra (Equus Quagga) Behaviour In A Restored Population Reveals Seasonal Resource Limitations, Charli De Vos, Alison J. Leslie, Jason I. Ransom

United States National Park Service: Publications

A once abundant species, plains zebra (Equus quagga), is declining across much of sub-Saharan Africa. Reintroduction efforts at Majete Wildlife Reserve, Malawi, have resulted in rapid population increases, but little is known about how such populations resemble natural populations socially or behaviourally, and what those attributes may reveal about restoration success. Incorporating behavioural knowledge into conservation efforts is an important tool for managing the effects of habitat fragmentation and resource competition. The aim of this study was to quantify the daylight time budget of both family and bachelor bands of reintroduced plains zebra to determine if such behaviours …

Predicting Livestock Depredation Risk By African Lions (Panthera Leo) In A Multi-Use Area Of Northern Tanzania, K. Beattie, E. R. Olson, B. Kissui, A. Kirschbaum, C. Kiffner

United States National Park Service: Publications

Human-wildlife conflicts, especially those involving large carnivores, are of global conservation and livelihood concern and require effective and locally-adapted prevention measures. Risk of lion attack on livestock (i.e. depredation) may vary seasonally and may be associated with variation in wild prey abundance or landscape characteristics. To test these competing hypotheses, we used a resource selection approach, and determined whether prey catchability (indicated by geo-spatial variables), or prey availability (indicated by modeled abundance recorded via camera traps) explained spatial and seasonal variation in livestock depredation risk by African lions on Manyara Ranch Conservancy, a multi-use area in northern Tanzania. Seasonal variation …

A Backbone Organization For Denver Based Environmental Justice Organizations 5280 For Environmental Justice, Allison Finnegan-Kihega

Regis University Student Publications (comprehensive collection)

Environmental injustices in Denver follow the same patterns that are seen throughout the country, which is that low-income People of Color are, relative to White people, disproportionately impacted by poor air and water quality, food deserts, displacement, and a phenomenon known as urban heat islands. The literature review conducted for this proposal revealed that despite the 2019 U.S Census Bureau indicating that Denver is 80.9 percent White, 29 percent Latino, and 10 percent Black, neighborhoods with predominantly Black and Latino residents are the neighborhoods experiencing environmental injustices in Denver.

For this project proposal, a literature review was conducted along with …

The Effect Of México’S Transition From Neoliberalism To Populism On Environmental Policy, Christina Marshall

Scripps Senior Theses

This article examines the transformation in Mexican politics from a neoliberal state to a one lead by a left wing populist leader and its impacts on environmental policy in the country. Specifically, looking at the election of AMLO in 2018 and prior neoliberal environmental policies (NAFTA and Pena Nieto's energy reform). This article looks at the motivations and outcomes of these policies to better understand environmental impact.

A Policy Analysis Of Lead Paint Disclosure Implementation In Residential Homes In Missoula Montana, Marissa Lein Lehner

Graduate Student Theses, Dissertations, & Professional Papers

Using Weimer and Vining’s (2017) framework and interviews with key actors, this policy analysis evaluates the implementation of federal lead paint disclosure requirements in Missoula Montana. Lead based paint was commonly used in homes built prior to 1978. Disclosure requires landlords and any persons selling a home to disclose known lead-based paint hazards to buyers and renters. The policy was enacted to promote informed decisions to avoid or reduce the risk of lead paint exposure. Lead paint disclosure serves a critical purpose to inform citizens of risk of lead paint in older housing, because any lead exposure is particularly detrimental …

Artificial Intelligence-Enhanced Decision Support For Informing Global Sustainable Development: A Human-Centric Ai-Thinking Approach, Meng-Leong How, Sin Mei Cheah, Yong-Jiet Chan, Aik Cheow Khor, Eunice Mei Ping Say

CCX Research

Sustainable development is crucial to humanity. Utilization of primary socio-environmental data for analysis is essential for informing decision making by policy makers about sustainability in development. Artificial intelligence (AI)-based approaches are useful for analyzing data. However, it was not easy for people who are not trained in computer science to use AI. The significance and novelty of this paper is that it shows how the use of AI can be democratized via a user-friendly human-centric probabilistic reasoning approach. Using this approach, analysts who are not computer scientists can also use AI to analyze sustainability-related EPI data. Further, this human-centric probabilistic …

Towards A Resilient Future: Federal Policies For Adapting The U.S. Coasts To Climate Change, Samuel Horowitz

Pitzer Senior Theses

Climate change is projected to have a devastating impact on the American coast, yet coastal communities and states have largely failed to prepare for projected impacts. This is in large part due to a lack of resources. This thesis analyzes innovative federal policy mechanisms that will address the current gap between actions and forecasted impacts, and will make U.S. coastal communities more resilient in the face of climate change.

Household Costs And Resistance To Germany's Energy Transition, Roger Karapin

Publications and Research

Germany is an exemplary case of an energy transition from nuclear energy and fossil fuels toward renewables in the electricity sector, but it also demonstrates repeated, increasingly successful counter-mobilization by energy incumbents and their allies. The course for Germany's energy transition was largely set with the adoption of a feed-in tariff law in 1990, but since then the energy transition has been altered by a series of policy-making episodes, each of which was shaped by the outcomes of the previous episodes; there has been a combination of reinforcing and reactive sequences. This article uses policy windows and advocacy coalition theory, …

Environmental Governance For Whom? Examining The Political, Institutional, Fiscal, And Legal Determinants Of State Environmental Agency Budget Policy In The Us, Andrew R. Duggan

Theses and Dissertations

Budgets are a prospective tool of governance, and appropriations are a planning vehicle reflecting: bureaucracies’ values, complex interactions, collective preferences, political influences, and available resources. Research spanning 30 years finds that environmental pollution is a key determinant of environmental budgets in the US, though myriad factors, actors, and subsystems are important to consider. Due to federalism and devolution of responsibilities and authorities, environmental governance falls largely to the states. While the dynamics that shape state environmental budget policy have received scholarly interest, theoretically-driven examinations of environmental appropriations remain limited within the public budgeting and environmental policy literature.

Using panel data …

Rights, Water, And Guardians: How Rights Of Nature Movements Are Reshaping Our Current Environmental Ethics And What These Policies Need To Be Successful, Megan Schmiesing

Pitzer Senior Theses

Giving legal rights to nature is no longer a fringe idea in international environmental law. Rights of Nature movements have gained traction in countries around the world, including Ecuador, Australia, India, Aotearoa New Zealand, and the United States. The act of organizing to recognize legal rights and legal personhood for nature represents a philosophical, moral, and political shift from previous anthropocentric values. Through two case studies in Aotearoa New Zealand and the United States, this thesis examines the policy language and the context and history that led to their creation. The Te Awa Tupua (Whanganui River Claims Settlement) Act and …

Sustainability, Urban Planning And Development: Sustainable And Self-Reliant Urban Development In Post- Pandemic Nepal, Ambika P. Adhikari, Keshav Bhattarai

Himalayan Research Papers Archive

COVID-19 pandemic is affecting many aspects of the society, economy and the way people live. The pandemic is also disrupting the process of physical planning and development in the cities. It will perhaps permanently change the way planners and policy makers think about the city and plan for its development. The residents and visitors will also find the city to be different from the pre-COVID-19 era. The emerging situation would likely require new ways of moving, working and living in the city, and building the different physical components of the city.

Cities around the world are experiencing varieties of unexpected …

Issues And Perspective On The Covid-19 And Nepal: An Introduction, Ambika P. Adhikari, Basu Sharma

Himalayan Research Papers Archive

Even though Nepal has relatively fewer Covid-19 cases as of 24 September 2020 (about 70,000 cases and more than 450 deaths), the numbers are on the rise. If this trend continues for a while, the likely consequences of the Pandemic would be no less severe than elsewhere. Further, Nepal’s next-door neighbor India is now experiencing a rapid rise in the virus infection rate and virus-related death toll. In fact, as of 24 September, 2020, India is seeing some about six million total Covid-19 cases, and more than 92,000 deaths. As India and Nepal have open borders, and as India is …

The Political Viability Of Carbon Pricing: Policy Design And Framing In British Columbia And California, Roger Karapin

Publications and Research

The adoption of climate policies with visible, substantial costs for households is uncommon because of expected political backlash, but British Columbia's carbon tax and California's cap-and-trade program imposed such costs and still survived vigorous opposition. To explain these outcomes, this paper tests hypotheses concerning policy design, framing, energy prices, and elections. It conducts universalizing and variation-finding comparisons across three subcases in the two jurisdictions and uses primary sources to carry out process tracing involving mechanisms of public opinion and elite position taking. The paper finds strong support for the timing of independent energy price changes, exogenous causes of election results, …
