African Environmental Change From The Pleistocene To The Anthropocene, Colin Hoag, Jens-Christian Svenning

Anthropology: Faculty Publications

This review explores what past environmental change in Africa—and African people's response to it—can teach us about how to cope with life in the Anthropocene. Organized around four drivers of change—climate; agriculture and pastoralism; megafauna; and imperialism, colonialism, and capitalism (ICC)—our review zooms in on key regions and debates, including desertification; rangeland degradation; megafauna loss; and land grabbing. Multiscale climate change is a recurring theme in the continent's history, interacting with increasingly intense human activities from several million years onward, leading to oscillating, contingent environmental changes and societally adaptive responses. With high levels of poverty, fast population growth, and potentially …

Ecological Niche Modeling Of The Genus Papio, Amanda J. Fuchs

Theses and Dissertations

Ecological niche modeling investigates how climatic variables have influenced taxonomic diversity in Papio. Models performed well suggesting climatic variables influence the distribution of baboon species. Niche overlap among all possible pairs of taxa determined that species exhibited significantly different niches. The results of these models support a parapatric speciation scenario.

How Governmental Greenhouse Gas Science Has Been Weathered Through Time And Why It Matters, Christopher Apple

STAR Program Research Presentations

Global consumption of materials and energy is accelerating. The rate of plant and animal species extinction is accelerating. On a finite Earth with a growing population, current consumption cannot continue sustainably. Greenhouse gases (GHGs) tell us an important part of this story. The Global Greenhouse Gas Reference Network, managed by scientists at NOAA’s Earth System Research Laboratory, is the largest greenhouse gas analysis network in the world. It has been shaped by scientific questions, stagnant funding despite rises in research costs, and the task of understanding how the Earth system will respond to a changing climate. The Network began by …

The Impact Weather Has On Nyc Citi Bike Share Company Activity, Mark Martinez

Journal of Environmental and Resource Economics at Colby

This paper seeks to figure out the effect weather has on individuals’ behavior. A more focused approach to determining this effect is seeing how different weather conditions ranging from the temperature, the precipitation, the amount of inches of snowfall and the wind speed effect the ridership of Citi Bikes throughout all four seasons. The approach of this research paper is using data from the National Climatic Data Center that focuses in on the weather found in Manhattan, New York and correlates each of the weather conditions to the total number of trips per day that is provided by the Citi …

A Good Kiwi Isn't Acidic: How Ocean Acidification Is Affecting The New Zealand Economy, Lily G. Hurley

Student Theses 2015-Present

In a country that houses a mere 4 million people, it is no wonder that agriculture has become the main facet of New Zealand’s economy. However, while the sheep and produce have flourished from land protection laws, marine life has struggled in recent years due to an increase in oceanic carbon levels. In an area of the Pacific that is so rich in coral reefs, Great White breeding areas, and a plethora of fish species, any upset of the natural preexisting chemical balance has a tangible impact. New Zealand is dealing with a crisis with huge economic and ecological ramifications. …

Environmental And Climatic Constraints On Large-Scale Camelina Production In Eastern Arkansas, Benjamin Robert Tracy

Graduate Theses and Dissertations

Camelina sativa is a cold weather crop that is typically grown in semi-arid environments in the Western United States, usually as a spring crop, but sometimes during the winter. Research analyzing climate data and soil hydrology is important to better understand the environmental and terrain conditions necessary for Camelina farming wherever it is proposed for large-scale production. This study focused on various conditions and constraints pertaining to the potential for Camelina as a crop biofuel in Eastern Arkansas. Due to interest in the economic potential of crop biofuels in this area, and in particular the low input costs for Camelina, …

"There Is No Planet B": Frame Disputes Within The Environmental Movement Over Geoengineering, David Russell Zeller Jr.

USF Tampa Graduate Theses and Dissertations

This dissertation examines frame disputes within the environmental movement over geoengineering proposals. Among other core framing tasks, social movement organizations must evaluate solutions and strategies for the social problems they seek to address. These framings are frequently disputed by those within the movement. Recent controversies regarding a set of climate intervention proposals commonly known as geoengineering offer the opportunity to document the ongoing construction of competing visions of environmental sustainability. The nascent quality of these proposals generate dissonant framings—episodes where organizations within the environmental movement exhibit disagreement about one or more core framing tasks—a situation Goffman referred to as a …

Environmental Migration From Egypt And Morocco: A Comparative Study, Mahir Ali Sheikh

Senior Projects Spring 2017

As economies continue to industrialize and grow, human activity and general changes in weather patterns have had an adverse effect on the global climate. Global temperature continues to rise creating changes in the climate of many different areas of the world, increasing the intensity of sudden and slow onset disasters. Less developed countries in the Middle East and North Africa particularly Egypt and Morocco are two economies that are negatively affected by certain dimensions of climate change. These dimensions of climate change have direct implications on internal and international migration patterns of these countries. Both countries rely on agriculture as …

Impacts Of Enso On Tornado Frequency, Intensity, And Geography Across The Eastern United States, Coryn Ann Collins

LSU Master's Theses

Tornadoes are a reoccurring severe weather hazard, with the highest rates globally occurring in the central United States. Despite their high frequency in the U.S., the scientific community’s disagreement of tornado activity during varying phases and intensities of the El Niño Southern Oscillation (ENSO) justifies a need for further research. In this study, tornado events from 1950 to 2014 in the U.S. east of the Rocky Mountains were investigated for seven phases of ENSO: strong, moderate, and weak El Niño/La Niña and the neutral phase. A seasonal Niño 3.4 index was used as the definition of ENSO. ENSO influences on …
