Anthropogenic landscapes : Owens Lake, CA
… Architecture, an important contributor to anthropogenic change, offers the opportunity to re-engage with the site. Stan Allen writes that "any work of architecture is (first) a transformation of the landscape." [1] Inevitably, architecture sits on and interacts with land, is composed of …

Partitioning Biological and Anthropogenic Methane Sources
… could have large and immediate impacts on anthropogenic radiative forcing. A more detailed understanding of the global methane budget could help guide effective emissions reductions efforts.</p><p>Humans have greatly altered the methane budget. Anthropogenic methane sources are …

Magnetism of anthropogenic airborne particulate matter
The global burden of disease associated with ambient particulate matter (PM<sub>2.5</sub>) pollution is the leading threat to life expectancy according to the Air Quality Life Index (AQLI) 2023 report. The study of airborne PM is key to understanding both its source, and its impact on human health. …

Investigating anthropogenic existential risks through art
… to answer the question of what can be done about anthropogenic threats to humankind. Local Warming is a large array of 72 collimated infrared emitting robotic heaters that provide a "bubble" of heat energy around the user as they pass through the installation. This project serves as an example of …

Detecting anthropogenic impacts on estuarine benthic communities
… interacting stressors. Separating the impacts of anthropogenic stressors from natural variability in the marine environment is extremely difficult. This is particularly true for estuaries, due to their inherent complexity and the prevalence of difficult-to-manage diffuse stressors. Successful …

Estimating global warming from anthropogenic heat emissions
The forcing from the anthropogenic heat flux (AHF), i.e. the dissipation of primary energy consumed by the human civilisation, produces a direct climate warming. Today, the globally averaged AHF is negligibly small compared to the indirect forcing from greenhouse gas emissions. Locally or …

Ecotoxicology of Natural and Anthropogenic Extreme Environments
… agricultural drainage ditches, an example of an anthropogenic extreme environment. </p> <p>Total glutathione, catalase, superoxide dismutase, and lipid peroxidation levels were of the same respective order of magnitude in the two vent gastropods, <italics>Alviniconcha</italics> sp. and …

Monitoring Anthropogenic Carbon in Cape Cod Bay
Coastal oceans are diverse regions which are highly important to human activity, coastal ecosystems, and carbon uptake. Parameters such as pH on the total scale (pHₜ), Dissolved Inorganic Carbon (DIC), and Total Alkalinity (TA) contribute to understanding the health of coastal waters such as Cape …

Developing in situ instrumentation to monitor anthropogenic change
To predict and mitigate anthropogenic impacts on the ocean, we must understand the underlying systems that govern the ocean’s response to inputs (e.g. carbon dioxide, pollutants). Analytical models can be used to generate predictions and simulate intervention strategies, but they must be grounded …

Forces Structuring Caddisfly Communities: Biogeographical to Anthropogenic Effects
Historical processes, patterns of diversification, and landscape characteristics have resulted in the distribution of biodiversity that forms the context in which local community interactions occur. These local dynamics include relationships among different species and interactions between species …

Impact of Anthropogenic Activities on Hydro-Climatological Variables
… environment has been significantly affected by anthropogenic activities. Between 1700s and 2000s, agricultural land area had quintupled and the extent of natural vegetation was globally reduced by half. Furthermore many scientists argue that the recent rise in CO2 levels in the atmosphere is …

Population and community responses to anthropogenic environmental changes
… Profiles; ROAPs) to explore the effects anthropogenic changes have on plant communities and bird populations. Chapter one investigates the influence of nutrient deposition on native prairie grass communities. I show that soil phosphorus levels alter plant diversity by changing the degree …

Historical anthropogenic emissions of carbon monoxide, 1850 - 2000
We present a bottom-up emission inventory of carbon monoxide (CO) from fossil fuel and biofuel combustion from 1850 to 2000. We reconstruct fuel consumption data of brick and cement industry, as well as production data of iron and steel industry. We develop technology divisions for the four …

Mineralogy-based global anthropogenic combustion-iron emission inventory
… by two to five orders of magnitudes. Anthropogenic combustion-iron emissions are thought to be the missing link in some of the ocean regions and are currently underestimated in inventories along with a poor fuel-based solubility representation approach in contrast to dust-iron …

Climatic and Anthropogenic Influences on Food and Water Security
… systems and their interaction with climate and anthropogenic factors. Specifically, it has the following research objectives: (1) to quantify the sensitivity of crop yields to droughts for major crops and investigate the association of various climate and anthropogenic factors on the change in …

Effects of anthropogenic land use on temperate mangrove forests
… sediments. Highlighting the integrated nature of anthropogenic impacts, this chapter emphasizes the need for holistic evaluations in assessing responses of complex natural systems to change. The second chapter investigates environmental controls on organic matter degradation in mangrove forests. …

Effects of anthropogenic change on animal cognition and emotion
… are less studied. In this thesis, I argue that anthropogenic change impacts animals’ mental states, with implications for both individuals (welfare) and populations (conservation). My first experiment explores the transition from keeping dairy cattle at pasture to housing them indoors full-time. …
