Negative Impacts Of The Beef Industry: Lab-Grown Meat, Stephanie Grass Aug 2019

Negative Impacts Of The Beef Industry: Lab-Grown Meat, Stephanie Grass

WRIT: Journal of First-Year Writing

The beef industry is harmful to the environment and human health and alternative solutions must be implemented in order to mitigate the effects of climate change. Water and grain are used in agriculture in abundance despite the negative environmental effects it causes. Cattle are the biggest contributors to greenhouse gas emissions in the sector, also contributing to climate change. Antibiotics are used in large quantities without regard to potential future consequences. One potential solution for this problem is lab-grown beef, which demands very little from the consumer and would take pressure off the environmental issues the beef industry creates. Lab-grown ...


Attendance Trends Threaten Future Operations Of America’S State Park Systems, Jordan W. Smith, Emily J. Wilkins, Yu-Fai Leung Jul 2019

Attendance Trends Threaten Future Operations Of America’S State Park Systems, Jordan W. Smith, Emily J. Wilkins, Yu-Fai Leung

Jordan Smith

This research examines how the operating expenditures of America’s state park systems will be affected by a continued growth in attendance consistent with observed trends as well as potential climate futures. We construct a longitudinal panel dataset (1984–2017) describing the operations and characteristics of all 50 state park systems. These data are analyzed with a time-varying stochastic frontier model. Estimates from the model are used to forecast operating expenditures to midcentury under four different scenarios. The first scenario assumes annual attendance within each state park system will continue to grow (or decline) at the same average annual rate ...

Blacklegged Tick (Ixodes Scapularis) Distribution In Maine, Usa, As Related To Climate Change, White-Tailed Deer, And The Landscape, Susan P. Elias May 2019

Blacklegged Tick (Ixodes Scapularis) Distribution In Maine, Usa, As Related To Climate Change, White-Tailed Deer, And The Landscape, Susan P. Elias

Electronic Theses and Dissertations

Lyme disease is caused by the bacterial spirochete Borrelia burgdorferi, which is transmitted through the bite of an infected blacklegged (deer) tick (Ixodes scapularis). Geographic invasion of I. scapularis in North America has been attributed to causes including 20th century reforestation and suburbanization, burgeoning populations of the white-tailed deer (Odocoileus virginianus) which is the primary reproductive host of I. scapularis, tick-associated non-native plant invasions, and climate change. Maine, USA, is a high Lyme disease incidence state, with a history of increasing I. scapularis abundance and northward range expansion. This thesis addresses the question: “To what extent has the range expansion ...


The Living Archive In The Anthropocene, Nora Almeida, Jen Hoyer Apr 2019

The Living Archive In The Anthropocene, Nora Almeida, Jen Hoyer

Publications and Research

This paper presents the concept of the living archive as a system which reflects how social behavior and cultural production are part of the Anthropocene. The authors explore how dominant narratives of both the Anthropocene and the archive work to consolidate power and maintain cultural and disciplinary divisions. The authors refute conceptions of the Anthropocene as a purely biophysical phenomenon that is alienated from cultural practice and of the archive as a comprehensive and nostalgic space. They then introduce the living archive as an alternative representational, creative, and reactive space and illustrate how the living archive can intervene in ecological ...

2016 - California Land Use And Management - A Resource Management Strategy Of The California Water Plan Mar 2019

2016 - California Land Use And Management - A Resource Management Strategy Of The California Water Plan

Miscellaneous Documents and Reports

Land use planning and management cuts across many resource management strategies. More efficient and effective land use is linked to several resource management strategies including watershed, water use efficiency, groundwater quality, flood management, parks and recreation, climate change adaptive management and agricultural lands stewardship. Directly development away from agricultural lands permits multi-objective management of these lands for agricultural preservation, floodplain management, water quality, habitat conservation, and sustainable development. In addition, planning for more compact and sustainable communities, both urban and rural, will assist in reducing reliance on the state-s water supply, and result in more efficient use of California’s ...

The International Whaling Commission—Beyond Whaling, Andrew J. Wright, Mark P. Simmonds, Barbara Galletti Vernazzani

Mark P. Simmonds, O.B.E.

Since its establishment in 1946 as the international body intended to manage whaling, the International Whaling Commission (IWC) has expanded its areas of interest to ensure the wider conservation of whales. Several key conservation topics have been taken forward under its auspices including climate change, chemical and noise pollution, marine debris and whale watching. Work on each of these topics at the IWC has grown substantially since the 1990s and remains ongoing. Important developments were the establishment of the Standing Working Group on Environmental Concerns in 1996 and the IWC’s Conservation Committee in 2003. Trying to address this diverse ...

2010 - California Agricultural Vision - Strategies For Sustainability

Miscellaneous Documents and Reports

California is a major contributor to the global food supply and to the national security of the United States. To keep pace with growing demand for food, as the world’s population continues to expand, California agriculture must remain profitable and competitive in a global market by efficiently using resources and controlling production costs. California faces unprecedented challenges to its sustainability in the form of pressures on its profitability and productivity related to water, regulations, labor, invasive species, urbanization and many other factors.


Ecological Considerations And Application Of Urban Tree Selection In Massachusetts, Ashley Mcelhinney Jan 2019

Ecological Considerations And Application Of Urban Tree Selection In Massachusetts, Ashley Mcelhinney

Masters Theses

Trees provide countless environmental, economic, and societal benefits to the urban environment, and may become increasingly important to maintaining environmental quality and human well-being in the face of increasing urbanization and climate change. However, trees in these urban areas are rapidly diminishing across the United States. Much of this loss can be prevented with proper planning and management, focused on selecting tree species that are both well-suited to the area’s growing conditions and able to survive the many stress factors in an urban setting. Choosing which tree species to plant in Massachusetts is especially challenging considering the lack of ...


A Multi-Scale Analysis Of Jaguar (Panthera Onca) And Puma (Puma Concolor) Habitat Selection And Conservation In The Narrowest Section Of Panama., Kimberly A. Craighead Jan 2019

A Multi-Scale Analysis Of Jaguar (Panthera Onca) And Puma (Puma Concolor) Habitat Selection And Conservation In The Narrowest Section Of Panama., Kimberly A. Craighead

Dissertations & Theses

Over the past two centuries, large terrestrial carnivores have suffered extreme population declines and range contractions resulting from the synergistic anthropogenic threats of land-use change and indirect effects of climate change. In Panama, rapid land use conversion coupled with climate change is predicted to negatively impact jaguar (Panthera onca) and puma (Puma concolor). This dissertation examined the environmental variables and scales influencing jaguar and puma habitat selection by season (annual, wet, and dry), using multi-scale optimized habitat suitability models and a machine-learning algorithm (Random Forests), in the narrowest section of Panama. The models derived from the data of an intensive ...
