Michael H. Wilson

Capstone Abstract

December 27, 2016

Flight of the Freshwater Fish

The Hudson River provides for millions of people as a path for commercial and private transportation, a source of food and energy, and perhaps most importantly for many living in the tri-state area as a destination for recreation and relaxation. The most overlooked feature of the river is how the wildlife shows clear signs of a changing climate and rapid environmental response to the impacts of global warming on the river.

Entire populations of fish species in the lower Hudson have been forced to leave the river …


Exploration Of Student Biodiversity Knowledge And Decision-Making For A Wildlife Conservation Socioscientific Issue, Ashley R. Alred Dec 2016

Exploration Of Student Biodiversity Knowledge And Decision-Making For A Wildlife Conservation Socioscientific Issue, Ashley R. Alred

School of Natural Resources: Dissertations, Theses, and Student Research

Global biodiversity, a foundation for ecosystem function, is diminishing at a rate unprecedented in the last 50 years. Biodiversity loss and ecosystem services deterioration is linked to increased food insecurity, reduced water quality and availability, decreased energy security, higher economic losses and human suffering (Millennium Ecosystem Assessment, 2005). Consequently, educators should invest in supporting students in their development of ecological understanding and formal decision-making skills so they are equipped with meaningful tools they can use as scientifically literate citizens. To contribute to that mission, this study seeks to explore student 1) comprehension and explanation of biodiversity concepts and 2) decision-making …


Groundwater Declines Are Linked To Changes In Great Plains Stream Fish Assemblages, Joshuah S. Perkin, Keith B. Gido, Jeffrey A. Falke, Kurt D. Fausch, Harry Crockett, Eric R. Johnson, John Sanderson Nov 2016

Groundwater Declines Are Linked To Changes In Great Plains Stream Fish Assemblages, Joshuah S. Perkin, Keith B. Gido, Jeffrey A. Falke, Kurt D. Fausch, Harry Crockett, Eric R. Johnson, John Sanderson

United States Geological Survey: Staff Publications

Groundwater pumping for agriculture is a major driver causing declines of global freshwater ecosystems, yet the ecological consequences for stream fish assemblages are rarely quantified. We combined retrospective (1950–2010) and prospective (2011–2060) modeling approaches within a multiscale framework to predict change in Great Plains stream fish assemblages associated with groundwater pumping from the United States High Plains Aquifer. We modeled the relationship between the length of stream receiving water from the High Plains Aquifer and the occurrence of fishes characteristic of small and large streams in the western Great Plains at a regional scale and for six subwatersheds nested within …


Factors Affecting Habitat Quality For Wintering Wood Thrushes In A Coffee Growing Region In Honduras, Brett A. Bailey Nov 2016

Factors Affecting Habitat Quality For Wintering Wood Thrushes In A Coffee Growing Region In Honduras, Brett A. Bailey

Masters Theses

Amongst the diversity of taxa that occur in the Neotropics, 200 migratory bird species that breed in temperate North America can be found. Many of these populations have seen significant declines since the 1960s. The Wood Thrush, Hylocichla mustelina, is one such species. Shade coffee and other agroforestry practices show potential for benefiting migratory species, but the quality of coffee habitat and optimal habitat characteristics for Wood Thrushes remain unknown.

I surveyed a spatially complex, agricultural landscape in Honduras outside the recognized winter range of the Wood Thrush and radio-tagged 46 individuals within rustic coffee farms during the winters …

Agenda: Flpma Turns 40, University Of Colorado Boulder. Getches-Wilkinson Center For Natural Resources, Energy, And The Environment

FLPMA Turns 40 (October 21)

The Bureau of Land Management (BLM) administers approximately 245 million acres of our public lands and yet, for most of our nation's history, these lands seemed largely destined to end up in private hands. Even when the Taylor Grazing Act of 1934 ushered in an important era of better managing public grazing districts and "promoting the highest use of the public lands," such use of our public lands still was plainly considered temporary, "pending its final disposal." It was not until 1976 with the passage of the Federal Land Policy and Management Act (FLPMA) that congress adopted a policy that …


Weights And Balances: Integrating Models For Prevention And Response To Southern California Offshore Oil Spills, Carmen Watts Clayton, Amoret Bunn Oct 2016

Weights And Balances: Integrating Models For Prevention And Response To Southern California Offshore Oil Spills, Carmen Watts Clayton, Amoret Bunn

STAR Program Research Presentations

Licensing offshore oil and gas reserves in the United States waters are overseen by the U.S. Department of the Interior’s Bureau of Safety and Enforcement (BSEE). The licensing application includes planning for any worst-case oil spill scenario between BSEE and the applicant based on lessons learned from historic offshore spills such as the Deepwater Horizon (2010), Exxon Valdez (1989), and the Union Oil Platform Blowout (1969). The process for planning to respond to oil spills involves coordination with multiple agencies, trustees, and stakeholders to ensure that oil spill responses consider multiple factors, including ecologically sensitive species, commercial transportation and fisheries, …

Compassion As A Practical And Evolved Ethic For Conservation, David Ramp, Marc Bekoff Sep 2016

Compassion As A Practical And Evolved Ethic For Conservation, David Ramp, Marc Bekoff

Marc Bekoff, PhD

The ethical position underpinning decisionmaking is an important concern for conservation biologists when setting priorities for interventions. The recent debate on how best to protect nature has centered on contrasting intrinsic and aesthetic values against utilitarian and economic values, driven by an inevitable global rise in conservation conflicts. These discussions have primarily been targeted at species and ecosystems for success, without explicitly expressing concern for the intrinsic value and welfare of individual animals. In part, this is because animal welfare has historically been thought of as an impediment to conservation. However, practical implementations of conservation that provide good welfare outcomes …

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

Environment and Nature Conservation Collection

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 set …

Hotspots, Extinction Risk And Conservation Priorities Of Greater Caribbean And Gulf Of Mexico Marine Bony Shorefishes, Christi Linardich Jul 2016

Hotspots, Extinction Risk And Conservation Priorities Of Greater Caribbean And Gulf Of Mexico Marine Bony Shorefishes, Christi Linardich

Biological Sciences Theses & Dissertations

Understanding the status of species is important for allocation of resources to redress biodiversity loss. Regional organizations tasked with managing threats to the 1,360 marine bony shorefishes of the Caribbean and Gulf of Mexico would benefit from a delineation of conservation priorities. However, prior to this study, conservation status was known for only one quarter of these shorefishes. Extinction risk assessment under IUCN Red List Criteria is a widely-used, objective method to communicate species-specific conservation needs. Data were collated on each species’ distribution, population, habitats and threats and experts at three Red List workshops assigned a global level extinction risk …


Developing A Sustainable Water Supply In The American West: The Case Of Rio Rancho, New Mexico, Hubert B. Stroud, Mary K. Kilmer Jun 2016

Developing A Sustainable Water Supply In The American West: The Case Of Rio Rancho, New Mexico, Hubert B. Stroud, Mary K. Kilmer

Suburban Sustainability

Suburban and urban communities in the American West are challenged by rapid population growth combined with limited natural resources. Supporting sustainable development is of great concern in this region and in similar regions throughout the world. This research examines the sustainability of the water supply within a rapidly growing suburban city in the American West. The city, Rio Rancho, New Mexico, began as an interstate land sales operation and rapidly became a “boom” town, in part because of its location near metropolitan Albuquerque.

Because of a very limited water supply and an increasing demand for water associated with population growth, …

The Mexican Water Forest: Benefits Of Using Remote Sensing Techniques To Assess Changes In Land Use And Land Cover, Maria F. Lopez Ornelas May 2016

The Mexican Water Forest: Benefits Of Using Remote Sensing Techniques To Assess Changes In Land Use And Land Cover, Maria F. Lopez Ornelas

Master's Projects and Capstones

In the past 30 years, anthropogenic activities like urbanization, agriculture, road fragmentation and deforestation have resulted in changes in the land use and land cover (LULC) in the Mexican Water Forest. Due to the important ecosystem services, and the natural resources this forest provides, in Mexico, it has become increasingly necessary to use new technologies and tools to support the planning, implementation and integration of forest management and conservation plans, as well as ecological and socioeconomic analysis of this ecosystem. Remote Sensing techniques and Geographic Information Systems (GIS) have been a true technological and methodological revolution in the acquisition, management …


Biodiversity Prioritization: A Comparison Of Data Types, Kari Norman May 2016

Biodiversity Prioritization: A Comparison Of Data Types, Kari Norman

Undergraduate Honors Capstone Projects

The identification of important areas for biodiversity is essential for effective allocation of limited conservation resources. Prioritizing regions for conservation based on biodiversity is typically done using global biodiversity maps created using range map data for one or more taxa. While the use of range maps makes pragmatic sense since large-scale survey data is rarely available, it is important to understand the sensitivity of the results to the use of range map data. We studied how prioritizations may change between data types using the North American Breeding Bird survey (BBS) and BirdLife International range maps as a comparison case study. …

The Coastal Monitor: Vol. 1, No. 2, John Tanacredi Ph.D.

The Coastal Monitor

At a recent event a colleague asked me, “So what do you do at CERCOM?” My immediate response was the “M” word fundamentally! After 45 years involved in environmental sciences, monitoring remains the most important and critical aspect of not only any field station in support of the academics conducted, but the seminal responsibility to be able, as a scientist, to reveal trends in the massive volume of data collected through routine monitoring exercises. It is extremely rare for a single data point, or even a single season of data, no matter how accurate the individual data point is, to …


The Measure Of Nematode Diversity In Response To Varying Management Practices And Features In Restored And Remnant Prairie Ecosystems, Heaven A. Hulshizer Apr 2016

The Measure Of Nematode Diversity In Response To Varying Management Practices And Features In Restored And Remnant Prairie Ecosystems, Heaven A. Hulshizer

UCARE Research Products

"Tallgrass prairies are the most endangered ecosystem in North America” (Helen et al 2013). “Surveys suggest that since European settlement, declines in area of native prairie range as high as 99.9%”(Sampson, Fred and Fritz Knopf 1994). Prairie ecosystem services are abundant and range from mitigating floods to promoting biodiversity. (USDA Forest Service).Given these benefits, restoring prairies and maintaining native areas should be an important conservation priority. Nematodes, the most abundant animal species on earth, have been used as bio-indicators of soil quality (Neher; Todd). To better understand the dynamics of nematode diversity in native and restored prairies we examines whether …


The Effectiveness Of The Colby College Electricity Competition On Promoting Electricity Conservation To Students, Jeff Vaz Jan 2016

The Effectiveness Of The Colby College Electricity Competition On Promoting Electricity Conservation To Students, Jeff Vaz

Journal of Environmental and Resource Economics at Colby

This paper examines the effectiveness of the Colby College electricity reduction competition in altering students’ behavior to conserve electricity. The Colby College electricity reduction competition is an information-based policy that Colby implemented to promote the conservation of electricity, which are a major contributor to greenhouse gas (GHG) emissions in the United States. The study analyzes if different residence halls reduce electricity consumption by different amounts during the competition period. Results indicate that only 4 of 22 residence halls reduced electricity usage during competition periods in a statistically significant manner. The study concludes that the electricity competition at Colby College is …


Malheur Occupation In Oregon: Whose Land Is It Really?, Char Miller Jan 2016

Malheur Occupation In Oregon: Whose Land Is It Really?, Char Miller

Pomona Faculty Publications and Research

The Malheur National Wildlife Refuge, a 187,757-acre haven for greater sandhill cranes and other native birds in eastern Oregon, is usually a pretty peaceful place. But its calm was shattered on Saturday, January 2 when Ammon Bundy and a group of armed men broke into and occupied a number of federal buildings on the refuge, vowing to fight should the government try to arrest them. Their insurrectionary goal appears to be, simply put, to destroy the national system of public lands – our forests, parks and refuges – that was developed in the late 19th century to conserve these …


Revised Distributional Estimates For The Recently Discovered Olinguito (Bassaricyon Neblina), Using Museum And Science Records, Beth E. Gerstner Jan 2016

Revised Distributional Estimates For The Recently Discovered Olinguito (Bassaricyon Neblina), Using Museum And Science Records, Beth E. Gerstner

Dissertations and Theses

In the context of global change, a necessary first step for the conservation of species is gaining a good understanding of their distributional limits. This is especially important for biodiversity hotspots with high endemism such as the Northern Andes. The olinguito (Procyonidae: Bassaricyon neblina) is a recently described, medium-sized carnivoran found in Northern Andean cloud forests. A preliminary distributional model was published along with the original description, and I here provide revised distributional estimates using updated locality records and more current ENM methods. I build ecological niche models in Maxent using occurrence data (georeferenced museum records and citizen science-derived photo-vouchers) …


Discontinuities Concentrate Mobile Predators: Quantifying Organism-Environment Interactions At A Seascape Scale, Cristina G. Kennedy, Martha E. Mather, Joseph M. Smith, John T. Finn, Linda A. Deegan Jan 2016

Discontinuities Concentrate Mobile Predators: Quantifying Organism-Environment Interactions At A Seascape Scale, Cristina G. Kennedy, Martha E. Mather, Joseph M. Smith, John T. Finn, Linda A. Deegan

Environmental Conservation Faculty Publication Series

Understanding environmental drivers of spatial patterns is an enduring ecological problem that is critical for effective biological conservation. Discontinuities (ecologically meaningful habitat breaks), both naturally occurring (e.g., river confluence, forest edge, drop-off) and anthropogenic (e.g., dams, roads), can influence the distribution of highly mobile organisms that have land- or seascape scale ranges. A geomorphic discontinuity framework, expanded to include ecological patterns, provides a way to incorporate important but irregularly distributed physical features into organism–environment relationships. Here, we test if migratory striped bass (Morone saxatilis) are consistently concentrated by spatial discontinuities and why. We quantified the distribution of 50 …

African elephants (Loxodonta africana) are imperiled by poaching and habitat loss. Despite global attention to the plight of elephants, their population sizes and trends are uncertain or unknown over much of Africa. To conserve this iconic species, conservationists need timely, accurate data on elephant populations. Here, we report the results of the Great Elephant Census (GEC), the first continent-wide, standardized survey of African savannah elephants. We also provide the first quantitative model of elephant population trends across Africa. We estimated a population of 352,271 savannah elephants on study sites in 18 countries, representing approximately 93% of all savannah …


An Examination Of Intrinsic Existence Value Towards Wildlife Of Columbus Zoo And Aquariums Tourists: Evaluating The Impact Of Behind The Scenes Programming, Robert Maxwell Lakes Jan 2016

An Examination Of Intrinsic Existence Value Towards Wildlife Of Columbus Zoo And Aquariums Tourists: Evaluating The Impact Of Behind The Scenes Programming, Robert Maxwell Lakes

Online Theses and Dissertations

Changes in climate and the corresponding environmental issues are major concerns facing the world today. Human consumption, which is leading the rapid depletion of the earth’s finite resources and causing a dramatic loss of biodiversity, is largely to blame (Pearson, Lowry, Dorrian, & Litchfield, 2014). American zoos and aquariums are positioned to create positive experiential relationships between zoo tourists and animals that have the potential to positively change the zoo tourists’ conservation behaviors. Challenges to changing the conservation behaviors of zoo tourists are many. One particularly important challenge is conservation/environmental education. Zoos and aquariums aim to provide effective and quality …


Human–Wildlife Conflict And Coexistence, Philip J. Nyhus Dec 2015

Human–Wildlife Conflict And Coexistence, Philip J. Nyhus

Philip J. Nyhus

Human interactions with wildlife are a defining experience of human existence. These interactions can be positive or negative. People compete with wildlife for food and resources, and have eradicated dangerous species; co-opted and domesticated valuable species; and applied a wide range of social, behavioral, and technical approaches to reduce negative interactions with wildlife. This conflict has led to the extinction and reduction of numerous species and uncountable human deaths and economic losses. Recent advances in our understanding of conflict have led to a growing number of positive conservation and coexistence outcomes. I summarize and synthesize factors that contribute to conflict, …
