A Periodic Matrix Population Model For Monarch Butterflies, Emily Hunt

Senior Honors Projects, 2010-2019

The migration pattern of the monarch butterfly (Danaus plexippus) consists of a sequence of generations of butterflies that originate in Michoacan, Mexico each spring, travel as far north as Southern Canada, and ultimately return to the original location in Mexico the following fall. We use periodic population matrices to model the life cycle of the eastern monarch butterfly and find that, under this model, this migration is not currently at risk. We extend the model to address the three primary obstacles for the long-term survival of this migratory pattern: deforestation in Mexico, increased extreme weather patterns, and milkweed degradation.

Integrated Modeling Of Land Use And Climate Change Impacts On Multiscale Ecosystems Of Central African Watersheds, Simon Nampindo

Doctoral Dissertations

Assessment and management of ecosystem services demands diverse knowledge of the system components. Land use change occurring mainly through deforestation, expansion of agriculture and unregulated extraction of natural resources are the greatest challenges of the Congo basin and yet is central to supporting over 100 million people. This study undertook to implement an integrated modeling of multiscale ecosystems of central African watersheds and model the impact of anthropogenic factors on elephant population in Greater Virunga landscape. The study was conducted at varied scales, regional, landscape, and community. Regional study included watershed analysis and hydrological assessment using remotely sensed data implemented …

Failure Of Democratic Consolidation: The Three Year Interlude Of Military Rule (1958-1962) In Burma, Zaw Thein

Masters Theses

Many scholars believe that the period between 1948 when Burma won Independence and 1962 when the military took over the country from the elected civilian government as the parliamentary democracy era. During this era, there was a three-year interlude where the military leaders ruled the country as the Caretaker Government- a euphemism for the three-year military interlude. My argument is that this interlude happened due to the growing strength of the military as an institution and the decline of political parties in Burma. The strength of the military institution was due to the civil war that broke out just after …

Furniture Design And Product Development Principles Considering End-Of-Life Options And Design For Environment Strategies, Mesut Uysal

Open Access Theses

During last decades, environmental issues come into prominence and some governmental or organizational regulations are legislated to reduce environmental impacts of products within their life cycle. At the same time, costumers consider not only price, quality, branding, uniqueness, availability but also environmental impact, safety, and overall sustainability of products they select. Therefore, producers are addressing environmental impact of products they are producing and also making changes to their production process. This project is addressing End-of-Life (EoL) Options of wooden furniture. ^ Although wood is eco-friendly and natural material, its technological process, use and disposal might have ecological problem and challenge. …

Automated Landing Site Determination For Unmanned Rotocraft Surveillance Applications, Justin Keith Mackay

Theses and Dissertations

Unmanned air vehicles have been increasing in their autonomous capabilities. This research furthers these capabilities by focusing on the automation of landing site determination for rotorcraft in urban environments. Automated landing saves energy and allows the aircraft to choose areas that are safe for people and the aircraft. Two methods are used to gather information about the terrain of potential landing sites. One method is 3D reconstruction from multiple camera images. The other method uses a range sensor to reconstruct the terrain. Both of these methods create an inertial terrain map of the environment in the form of a point …

Deforestation And The Islamic Stewardship Ethic, Misbah Alghamdi

Theses

Forests throughout the world continue to be in danger as a result of human activity. Although the average rate of deforestation has recently slowed, in some countries the rate of forest degradation remains high. Currently, numerous management efforts are underway to address this environmental crisis. In some cases the achievement of forest preservation has been related to ethical choices. One moral posture, anthropocentrism, which views human beings as central and the most significant species on the planet, is believed to be a primary cause of environmental degradation includes deforestation.

This paper aims to address deforestation with the reconfiguration of an …

The Impact Of World Bank’S Conditionality-Ownership Hybrid On Forest Management In Cameroon: Policy Hybridity In International Dependence Development, Asongayi Venard

Electronic Theses and Dissertations

Many developing countries depend on the World Bank for development assistance, which the Bank often provides with policy reform conditions. Resistance to World Bank’s conditionality caused the Bank to posit “ownership” as a country’s real assent to its development policies. The combination of ownership and conditionality invalidates the neocolonial, false-paradigm and dualism theses in explaining the international dependence development model. This study explains this model by investigating how the relationship between conditionality and ownership in the context of this model impacts forest management in Cameroon.

Integrating theoretical and methodological insights mainly from political science, economics, geosciences, and sociology, the study …

Cadê O Mico? Where Is The Tamarin?: Locating Monkeys In The Politics Of Land And Conservation In Rio De Janeiro, Brazil, Analía Villagra

Dissertations, Theses, and Capstone Projects

The golden lion tamarin is a small, endangered monkey found in only a few municipalities in the state of Rio de Janeiro, Brazil. This dissertation explores the project to conserve this rare primate, a project that links together agrarian reform, forest restoration, agroforestry, and conservation biology. Informed by Brazil's social and political history, and drawing from 12 months of fieldwork conducted in 2008 and 2010, this dissertation argues that by looking carefully at and for the tamarin, we discover the interrelated political, social, and animal relationships that weave together to produce conservation in southeastern Brazil.

Evaluating The Potential Risks And Rewards In The Implementation Of A Redd+ Policy In Uganda, Sage Schaftel

Pitzer Senior Theses

In this thesis, I analyze the potential for a REDD+ program to succeed in Uganda at this time, and I explore why this may or may not be possible. REDD+, which stands for Reducing Deforestation and Forest Degradation, aims to enhance carbon stocks while also conserving and sustainably managing forests. In doing so, REDD+ not only works to offset carbon emission levels and conserve forests and forest biodiversity, but also provides financial benefits to REDD+ participant countries, thus improving the livelihoods of local people living adjacent to forests. This program is widely regarded as the most effective and least risky …

Subsistence And Biodiversity Conservation In The Sundarban Biosphere Reserve, West Bengal, India, Priyanka Ghosh

Theses and Dissertations--Geography

My dissertation research investigates the impacts of biodiversity conservation on the local population living in the Sundarban Biosphere Reserve (SBR). More specifically, the research examines the impacts of conservation on local fishing communities living on the edge of the Sundarban Reserve Forest. In addition, it examines the causes and characteristics of conflicts between the biosphere reserve managers and the local fishing communities over the resource use of the biosphere reserve. The research project also explores the impacts of ecotourism on the local population that lives on the edge of the Sundarban Tiger Reserve (STR). STR is one of the important …
