A New Adaptive Landscape: Urbanization As A Strong Evolutionary Force, Lauren Christie Breza Dec 2015

A New Adaptive Landscape: Urbanization As A Strong Evolutionary Force, Lauren Christie Breza

Masters Theses

Urbanization is rapidly increasing as human population growth steadily grows, but there is little consensus of the ecological consequence of this population shift and almost no information of the evolutionary consequences for local biodiversity. Nearly two-thirds of the world’s population will live in city centers by 2050 with profound impacts on landscapes that can act as important agents of selection. This study aims to identify 1) the net effect of urbanization on species richness, 2) how phylogenetic diversity varies between urban and rural sites, and 3) the strength of urbanization as a selection pressure. First, a meta-analysis was conducted in …


Urban Agriculture And Ecosystem Services: A Typology And Toolkit For Planners, Kathleen Doherty Nov 2015

Urban Agriculture And Ecosystem Services: A Typology And Toolkit For Planners, Kathleen Doherty

Masters Theses

This thesis makes the connection between urban agriculture and a specific suite of ecosystem services and lays out a typology and toolkit for planners to take advantage of these ecosystem services. The services investigated here are: food production, water management, soil health, biodiversity, climate mitigation, and community development benefits. Research from a variety of fields was aggregated and synthesized to prove that urban agriculture can be beneficial for human as well as environmental health.

A set of urban agriculture typologies was generated to illustrate best practices to maximize a particular set of ecosystem services. The typologies are: production farm, stormwater …


Protecting Ecosystems, Culture, And Human Rights In Chile Through Indigenous And Community-Conserved Territories And Areas, William G. Crowley Aug 2015

Protecting Ecosystems, Culture, And Human Rights In Chile Through Indigenous And Community-Conserved Territories And Areas, William G. Crowley

Capstone Collection

In environmental conservation circles around the world, the contributions of indigenous peoples and local communities to the sustainable maintenance of ecosystems and natural resources are being given increased attention. Whether for cultural, spiritual, economic, or other purposes, the use of traditional and local knowledge of habitat and resource management is slowly making its way into the modern environmental movement, and is being incorporated into the dominant conservation paradigms. These managed areas, known as Indigenous and Community-Conserved Territories and Areas, or ICCAs, are defined by the International Union for Conservation of Nature as “natural and/or modified ecosystems containing significant biodiversity …


The Suitability Of Habitats And The Effects Of Human Activities In Osupuko And Olepolos Wildlife Sanctuaries On Maasai Giraffes, Sydney P. Davis May 2015

The Suitability Of Habitats And The Effects Of Human Activities In Osupuko And Olepolos Wildlife Sanctuaries On Maasai Giraffes, Sydney P. Davis

Undergraduate Honors Theses

Habitat quality and resource availability within wildlife dispersal areas in the Amboseli ecosystem are experiencing degradation due to pastoralism and agriculture by humans, which negatively affects the wildlife species that utilize these dispersal areas. Maasai giraffes are a common species that utilize these areas, but information on how human activities and the presence of domestic livestock affects the Maasai giraffe is limited. This study was conducted in two wildlife sanctuaries: Osupuko and Olepolos. Habitat condition assessment was done to determine the quality of habitats found within each sanctuary. The Point-Centered Quadrat Method was used to determine the number of five …


Innovative Governance And Natural Resource Management In Kenya: Procedural And Substantive Outcomes Of Civil Society Participation, Jane Omudho Okwako May 2015

Innovative Governance And Natural Resource Management In Kenya: Procedural And Substantive Outcomes Of Civil Society Participation, Jane Omudho Okwako

Dissertations

Kenya’s environmental sector is embracing co-management to address major threats to wildlife. In the past two decades, the Municipal-Community-Private Sector Partnership (MCPP) model evolved to address the threats. This dissertation seeks to explain variations in partnership outcomes. It evaluates whether the model as introduced empowers communities to be conservation stewards.

This study hypothesized the impact of five variables. These are decentralization of power, elite support, capacity of community organizations, partnership formalization, and resources expended. The findings confirm that three variables are indispensable and two minimally influence empowerment. More decentralized management structures are enabling and supportive of empowerment. However, empowerment is …


School Gardens: Cultivating A Child’S Nutritional Habits, Environmental Knowledge, And Sustainability Practices, Jeffrey Meltzer Jan 2015

School Gardens: Cultivating A Child’S Nutritional Habits, Environmental Knowledge, And Sustainability Practices, Jeffrey Meltzer

Honors Theses

School gardens have existed since the late nineteenth century and today are becoming increasingly popular in many parts of the world, including where I studied in Maine and Australia (AUS). Multiple organizations support school gardens in Maine, including the Maine School Garden Network, which has over 125 registered school gardens. In AUS, the Stephanie Alexander Kitchen Garden Foundation primarily supports the school garden movement and has over 800 registered school gardens. While many researchers have studied school gardens, few have compared two countries, focused on environmental sustainability, or investigated Maine in particular. This thesis combines information from literature reviews, and …


Behavioral Response Of Pacific Lamprey (Entosphenus Tridentatus) To Predator Odors, Laurie L. Porter Jan 2015

Behavioral Response Of Pacific Lamprey (Entosphenus Tridentatus) To Predator Odors, Laurie L. Porter

All Master's Theses

Pacific lamprey (Entosphenus tridentatus), a species facing serious threats to their existence, experience a number of challenges in reaching their desired spawning grounds during the adult migratory phase, and predators are suspected to be one of these challenges. Understanding if Pacific lamprey respond to predator odorants may provide a management tool for use in conjunction with attractants in guiding lamprey to suitable spawning habitat and deterring them from poor habitat. Previous research has failed to explore Pacific lamprey response to predator odorants, although much research exists on attractant odorants. In our study, we tested Pacific lamprey response to …


Influence Of Landscape On Gene Differentiation In The American Pika (Ochotona Princeps) Within The Interstate 90 Snoqualmie Pass Corridor, Craig P. Fergus Jan 2015

Influence Of Landscape On Gene Differentiation In The American Pika (Ochotona Princeps) Within The Interstate 90 Snoqualmie Pass Corridor, Craig P. Fergus

All Master's Theses

Understanding the impact of different landscape features on the movement of genes among populations can be helpful in managing wildlife populations. Our study used GIS tools to compare genetic connectivity among 13 American pika (Ochotona princeps) habitat patches across an approximately 77 square km area adjacent to Interstate 90 near Snoqualmie Pass, WA. Tissue samples were collected from 85 individuals and genotyped at six microsatellite loci to determine genetic differentiation among each pair of patches. A variety of models estimating the influence of landscape factors on gene flow were then used to find “resistance scores” between each pair …


A Gis Assessment Of Ecoregion Representation In Chile's Existing And Proposed Integrated Network Of Protected Areas, Jessica Schutz Jan 2015

A Gis Assessment Of Ecoregion Representation In Chile's Existing And Proposed Integrated Network Of Protected Areas, Jessica Schutz

Graduate Student Theses, Dissertations, & Professional Papers

Chile's state designated protected areas are reported to show representation bias and to be unable to meet conservation goals. Private protected areas are considered an important tool to resolve these issues, which has led to support for increasing the role of private protected areas in Chile and creating an integrated public-private protected area network. But the validity of the capacity of private protected areas to fix Chile's state protected area network bias, and the advantage of creating an integrated protected area network, have not been assessed. This study uses the most recent data on Chile's state, private, and international protected …
