Non-Conventional Vehicles As A Way Towards Carbon Neutrality In Iceland, Julia Sokolowska
Independent Study Project (ISP) Collection
Paris Agreement’s chief objective is to protect the Earth and its inhabitants from a point of no return, when the effects of climate change will be so intense that they will shift the equilibrium of ecosystems. The distinctiveness of this international environmental treaty is that it does not impose climate change mitigation measures, but rather allows nation states to create their own set of measures, the NDCs, to reach the global warming of ‘well below 2oC’ by the end of the century. Thus, Iceland has submitted its own NDC, the Climate Action Plan 2018-2030, which has an ambitious goal of …

Development Of A Modified Floristic Quality Index As A Rapid Habitat Assessment Method In The Northern Everglades, Rebakah E. Gibble, Donatto D. Surratt
United States National Park Service: Publications
Floristic quality assessments (FQA) using floristic quality indices (FQIs) are useful tools for assessing and comparing vegetation communities and related habitat condition. However, intensive vegetation surveys requiring significant time and technical expertise are necessary, which limits the use of FQIs in environmental monitoring programs. This study modified standard FQI methods to develop a rapid assessment method for characterizing and modeling change in wetland habitat condition in the northern Everglades. Method modifications include limiting vegetation surveys to a subset of taxa selected as indicators of impact and eliminating richness and/or abundance factors from the equation. These modifications reduce the amount of …

Fire Monitoring Handbook
United States National Park Service: Publications
Fire is a powerful and enduring force that has had, and will continue to have, a profound influence on National Park Service (NPS) lands. Fire management decisions within the National Park Service require information on fire behavior and on the effects of fire on park resources. With good reason, the public is holding park management increasingly accountable, especially in the area of fire management. Federal and state agencies are instituting progressively more stringent guidelines for burning, monitoring, and evaluation. The impetus behind these guidelines and the purpose of this handbook are to ensure that management objectives are being met, to …

The Impact Of Extreme Heat On Environmental Justice Communities In California: Assessing Equity In Climate Action Plans, Karishma S. Becha
Master's Projects and Capstones
Climate change projections suggest extreme heat events will be more frequent over the next few decades. Extreme heat has both negative environmental and social impacts as it affects energy security, public health by increasing the risk of heat-related illnesses and stresses food and crop supply through prolonged droughts. The impacts of extreme heat will also disproportionately affect communities of low economic status. Because of this, there is a need for better climate action plans that can adapt to and mitigate the impacts brought upon by extreme heat that does not disproportionately impact vulnerable communities. This research analyzed local government Climate …

In advocating for coastal resilience, environmental nonprofits have been identified in the literature as actors with critical roles in addressing coastal issues such as sea-level rise, flooding and shoreline management. In recent times, shoreline management has emerged as one of the foremost areas of focus expedient for the achievement of coastal resilience, and the …
The Effectiveness Of The European Union’S Environmental Policies, Wendolyn Borkoski
The Effectiveness Of The European Union’S Environmental Policies, Wendolyn Borkoski
Undergraduate Theses and Capstone Projects
The European Union has some of the highest environmental standards in the world. However, multiple member states fail at reaching the deadlines set by the European Union (EU). This thesis examines the effectiveness of the European Union’s environmental directives on gaining compliance from member states to reach the agreed-upon standards. This is assessed by using three European Union directives from different environmental areas and analyzing their requirements. Each directive represents either a hierarchical policy, negotiated policy, or voluntary policy transfer. This study hypothesizes that the hierarchical policy, represented by EU Directive 2008/98/EC, will be more effective at gaining compliance than …
Protecting Water Quality In Virginia: Recommendations To Combat Sea Level Rise And Increased Storm Events, Madhavi Kulkarni
Protecting Water Quality In Virginia: Recommendations To Combat Sea Level Rise And Increased Storm Events, Madhavi Kulkarni
Virginia Coastal Policy Center
Impairment of Virginia waters is tied to coastal storm hazards and sea level rise because excess floodwaters are contaminated by flood-exposed industrial and residential facilities, and these toxic floodwaters flow into the state’s water bodies. In Virginia, thousands of industrial facilities can potentially be subjected to the effects of stormwater flooding, hurricane storm surge, and sea level rise, in turn affecting water quality. Failing or unmaintained septic systems also pose a major threat to the quality of Virginia waters that increases with recurrent inundation by flood waters. A combination of changes to law and policy and investment in infrastructure are …

Indigenous Communities Versus Oil Companies: Identifying Trends In Tactics And Success Of Indigenous-Led Anti-Petroleum Movements In The Ecuadorian Amazon, Ella V. H. Carlson
Independent Study Project (ISP) Collection
In roughly the last 50 years, the Ecuadorian Amazon has become the epicenter of petroleum production in Ecuador. As oil companies attempt to exploit more and more of the rainforest, they have encroached on indigenous lands, leading to violations of indigenous rights through environmental destruction. As their territories have been invaded, indigenous groups throughout the Amazon have formed movements large and small in resistance to petroleum activities. Scholars have studied select campaigns in the past, but the literature lacks a comparative review of the characteristics of those movements. This paper compiles histories of seven campaigns against petroleum in the Ecuadorian …

Acoustically Advertising Male Harbour Seals In Southeast Alaska Do Not Make Biologically Relevant Acoustic Adjustments In The Presence Of Vessel Noise, Leanna P. Matthews, Michelle E.H. Fournet, Christine Gabriele, Holger Klinck, Susan E. Parks
United States National Park Service: Publications
Aquatically breeding harbour seal (Phoca vitulina) males use underwater vocalizations during the breeding season to establish underwater territories, defend territories against intruder males, and possibly to attract females. Vessel noise overlaps in frequency with these vocalizations and could negatively impact breeding success by limiting communication space. In this study, we investigated whether harbour seals employed anti-masking strategies to maintain communication in the presence of vessel noise in Glacier Bay National Park and Preserve, Alaska. Harbour seals in this location did not sufficiently adjust source levels or acoustic parameters of vocalizations to compensate for acoustic masking. Instead, for every 1 dB …

Context In human-dominated landscapes, habitat fragmentation and barriers to movement can interrupt gene flow. While often considered at a local extent, regional analyses are also needed to reveal broader landscape-mediated population processes.
Objectives To explore the relationship between patterns of gene flow and fragmentation resulting from urbanization across southern California, we used the bobcat as an indicator species. We assembled data for a landscape level genetic analysis across southern California from both archived and new samples, including two northern Californian populations for comparison, to identify local and regional areas affected by isolation.
Methods Our regional analyses focused on a dataset …
Asynchronous Carbon Sink Saturation In African And Amazonian Tropical Forests, Wannes Hubau, Simon L. Lewis, Et. Al. Authors
Asynchronous Carbon Sink Saturation In African And Amazonian Tropical Forests, Wannes Hubau, Simon L. Lewis, Et. Al. Authors
United States National Park Service: Publications
Structurally intact tropical forests sequestered about half of the global terrestrial carbon uptake over the 1990s and early 2000s, removing about 15 percent of 1–3 anthropogenic carbon dioxide emissions. Climate-driven vegetation models 4,5 typically predict that this tropical forest ‘carbon sink’ will continue for decades . Here we assess trends in the carbon sink using 244 structurally intact African tropical forests spanning 11 countries, compare them with 321 published plots from Amazonia and investigate the underlying drivers of the trends. The carbon sink in live aboveground biomass in intact African tropical forests has been stable for the three decades to …

Estimation Of Available Epinephrine Dose In Expired And Discolored Autoinjectors Via Quantitative Smartphone Imaging, Amirus Saleheen, Bill M. Campbell, Rebecca A. Prosser, Christopher A. Baker
United States National Park Service: Publications
Epinephrine autoinjectors (EAIs) are important first aid medications for treating anaphylaxis. A 10-fold price increase over the past 12 years and evidence that expired EAIs may still contain significant doses of available epinephrine have motivated interest in the efficacy of expired EAIs as treatments of last resort. Degradation of expired EAIs, which can be caused by improper storage conditions, results in various degrees of discoloration of the epinephrine solution. Previous studies have determined that significant epinephrine remains available in expired EAIs, but these have only considered EAIs that show no discoloration. Here, we investigate the potential for colorimetric estimation of …
