Alpine Plant Communities Of The White Mountains Of New Hampshire: Aboveground Plant Diversity And Abundance Correlated To Belowground Factors, Timothy Maddalena-Lucey

Antioch University Dissertations & Theses

Alpine plant communities are fragile complex systems that may be threatened by climate change. Patterns of climate-driven soil warming are shown to have lasting effects on ecosystem nutrient cycles, alpine plant phenology, and belowground soil biotic activity. There are concerns in the alpine mycorrhizal research community as to how belowground fungal biomass will react to climate-driven soil warming. To address these concerns I asked in this study what are the correlations between belowground factors such as collective ectomycorrhizal (EcM) and ericoid mycorrhizal (ErM) percent colonization, pH, and soil depth to bedrock and aboveground plant diversity and richness. In 2018, on …

An Acoustic Monitoring Method For Assessing River Dolphin Presence And Changes In The Context Of Anthropogenic Development, Charles A. Muirhead

Graduate Masters Theses

Populations of river dolphins throughout Asia are in decline as a direct result of intensified anthropogenic activity along river systems. Water development projects, land use change, contamination, and intensified fishing practices are known factors contributing to the probable extinction of the Yangtze river dolphin (Lipotes vexillifer) and declining populations of the South Asian river dolphin (Platanista gangetica spp.), Irrawady dolphin (Orcaella brevirostris), and finless porpoise (Neophocaena a. asiaeorientalis). Although not yet as extensive, river system development in South America is following a similar path as that of Asia, with impacts on dolphin species likely to follow. Currently, the Amazon river …

Relationships Among Biodiversity Dimensions Of Birds In Nebraska, Nadejda Mirochnitchenko

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

Biological diversity, or biodiversity, is a multi-dimensional concept that can be decomposed to measure information about taxonomic, phylogenetic, and functional variation within communities. Although the dimensions of biodiversity are interrelated, the assumption that measuring one dimension of diversity can inform about patterns in another dimension does not necessarily follow from theory or empirical study. The relationships among biodiversity dimensions is not well understood, nor how differences among dimensions could influence conservation decision making. Using the avian community as a study system, we explored the relationships of breadth metrics from the taxonomic, phylogenetic, and functional dimensions among each other and across …

An Evaluation Of Deterrent Methods Utilized To Prevent Crop Raiding By African Elephants (Loxodonta Africana) In The Kasigau Wildlife Corridor, Kenya, Rebecca Lynn Von Hagen

Masters Theses & Specialist Projects

Escalating human elephant conflict (HEC) continues to be a contributing factor

towards elephant decline, and crop raiding is the most common form of negative

human-elephant interactions. For communities that cannot reverse or prevent crop

raiding, it is necessary to contain HEC events through deterrent measures. Few

deterrent measures exist that combine practicality and affordability while also

preventing habituation by elephants. This project focused on comparing the efficacy of

deterrent methods to assess which was the most successful at preventing elephants

from entering crops in the farming community of Sasenyi, Kenya. In this paired-control

study, four deterrent methods were evaluated: acacia …

Seabird Distribution And Oil & Gas Potential Along The Northern Sea Route, Russia: An Arctic Marine Conservation Case Study, Meghan Kelly

Sustainability and Social Justice

Seabirds are indicator species for the marine environment. Their populations are simultaneously affected by access to food resources and anthropogenic pressures including direct disturbance and habitat degradation associated with industrial development (Parsons et al. 2007). Therefore, using seabird distribution as a policy-relevant indicator for the Arctic marine environment supports an ecosystem based management approach aimed at protecting sensitive habitats from increased offshore oil and gas development.

This research identifies seabird habitat in the Russian Arctic utilizing in situ seabird observations from the Northern Sea Route to create a species distribution model. The spatial location of these areas will be compared …

Intensive Land Use And Conservation Planning At The University Of Central Florida, Chelsea R. Piner

The Pegasus Review: UCF Undergraduate Research Journal

Conservation strategies are necessary for cities to meet regional goals of sustainability, but commitments and collaborative efforts among influential stakeholders for economic and developmental growth frequently hinder conservation efforts. This study analyzes how planning documents influence conservation at the University of Central Florida (UCF). I use an inductive method of analysis to explore the stated conservation goals and commitments of UCF's Campus Master Plan. I then compare these objectives with the behaviors of the institution. This research indicates that the absence of collaborative efforts among agencies has resulted in UCF undermining its academic mission. Intensive land-use has sparked global environmental …

Kori Bustards (Ardeotis Kori) Respond To Vegetation Density And Elevation In The Northern Tuli Game Reserve, Botswana L'Abondance De L'Outarde Kori (Ardeotis Kori) Varie Selon La Végétation Et L'Élévation Dans La Réserve De Chasse De Northern Tuli, Botswana, Kathryn R. Mccollum, Larkin A. Powell, Andrei Shyman, Mary Bomberger Brown, John P. Carroll

School of Natural Resources: Faculty Publications

Conservation planning and decision making for species of concern requires precise information on abundance and habitat associations. We conducted transect surveys throughout the Northern Tuli Game Reserve, Botswana during June–July 2014 and May– July 2015 to estimate the occupancy and abundance of Kori Bustards (Ardeotis kori). The probability of occupancy of Kori Bustards was greater in areas with tree canopy cover ≤ 50% (ψ2014 = 0.37, SE ± 0.09; ψ2015 = 0.39, SE ± 0.06) when compared with areas with tree canopy cover > 50% (ψ2014 = 0.00, SE ± 0.00; ψ2015 = 0.00, SE ± 0.00). Densities of Kori Bustards …

The Effect Of Size On Juvenile Green Sturgeon (Acipenser Medirostris) Behavior Near Water-Diversion Fish Screens, Jamilynn B. Poletto, Dennis E. Cocherell, Natalie Ho, Joseph J. Cech Jr., A. Peter Klimley, Nann A. Fangue

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Anthropogenic water management projects and facilities that alter the local and regional hydrology of riverine environments greatly influence the behavior, physiology, and survival of native fishes. To mitigate for losses of native fishes at these structures, many are outfitted with fish-exclusion screens to reduce entrainment. The effect of fish size and age on behavior near fish screens, however, is largely unknown. Therefore, we tested two size classes of juvenile green sturgeon (Acipenser medirostris; small, early juveniles: 9.2 ± 0.2 cm fork length [FL], 6.9 ± 0.3 g; intermediate juveniles: 18.8 ± 0.2 cm FL, 36.9 ± 0.8 g) …

A Case-Study Of The African Leopard (Panthera Pardus Pardus) Population On The Nambiti Private Game Reserve, Erica Castaneda

The Nambiti Private Game Reserve in KwaZulu-Natal, South Africa is a nature reserve that aids in the conservation of some of the world’s most renown species. This includes members of the "Big Five," which is comprised of the African lion (Panthera leo), the African elephant (Loxidonta africana), the Cape buffalo (Syncerus caffer), the black & white rhinoceroses (Diceros bicornis and Ceratotherium simum, respectively), and the African leopard (Panthera pardus pardus). These animals represent the top five African animals desired by trophy hunters and by tourists hoping to view wildlife (Caro …

Protected Area Planning And Management: Supporting Local Stakeholder Participation With An Asset-Based, Biocultural Approach, Nicole M. Wengerd

Antioch University Dissertations & Theses

Given the uncertainties and risks of anthropogenic climate change, the urgency to conserve biodiversity has renewed urgency that has prompted a number of international forums, treaties, and agencies to advocate for the establishment of new and/or expansion of existing protected areas. One of the most broadly recognized efforts to expand the global protected area network can be found in the Aichi Biodiversity Targets, outlined in the Convention on Biological Diversity Strategic Plan for 2011-2020, adopted in 2010 by 196 countries. Target 11 calls for the expansion of terrestrail and inland water areas, as well as coastal marine areas. While the …

Habitat Ecology, Trophic Interactions, And Distribution Of Endangered Himalayan Musk Deer In The Nepal Himalaya, Kapil Kishor Khadka

Graduate Theses and Dissertations

This dissertation seeks to explore and assess the habitat selection, trophic interactions and distribution of Himalayan musk deer. Chapter one deals with seasonal diet analysis of musk deer along with the overlap in consumption with livestock during summer. Microhistological technique was employed to assess dietary consumption. Results showed that Abies spectabilis, Pinus wallichiana, and Berberis species constituted the major portion of musk deer’s diet. Dietary breadth measured by the Shannon index was found higher in winter compared to summer. Although musk deer and livestock shared a considerable number of plant species in their diets, the consumption however was significantly different …

An Evaluation Of Northern Bobwhite Conservation Research: A Call For Large-Scale Studies, Lex J. Gomez, Kelly S. Reyna

National Quail Symposium Proceedings

Northern bobwhite (Colinus virginianus) populations have declined throughout the species’ range since the 1960s. Habitat loss and degradation are thought to have largely contributed to this decline by reducing the amount of space and resources required to sustain viable quail populations. Previous studies have attempted to address this issue by focusing on ranch-level management of bobwhites instead of on the effectiveness of large-scale techniques. Here, we review current and historical studies that have facilitated the implementation of management techniques on multiple scales. In doing so, we will also reveal the shortcomings of such studies by highlighting their narrowed …

Long-Term Population Stability In The Greater Red Hills Region Amidst Range-Wide Declines: A Case For Integrated Management, Theron M. Terhune Ii, D. Clay Sisson, William E. Palmer, Shane D. Wellendorf

National Quail Symposium Proceedings

All natural habitats possess inherent conservation value, including the presence of rare or endemic species, provision of ecosystem services, historic landmarks, or resources harvested. Large-scale loss of natural habitats and deterioration of fire-mediated habitats has caused precipitous declines of native fauna and flora in the southeastern US. The role of private landholdings in wildlife and conservation is often underestimated, and consumptive use of wildlife is commonly viewed as counterproductive to sustainability. However, in the Greater Red Hills region (GRH) of north Florida and south Georgia, intentional management for northern bobwhite (Colinus virginianus) on private lands has not only …

The Role Of Joint Ventures In Northern Bobwhite Conservation, Stephen Demaso

National Quail Symposium Proceedings

Partnerships are crucial part of northern bobwhite (Colinus virginianus) conservation. A key principle is that no single entity can effectively address the complex landscape-level conservation issues to sustain populations and their supporting habitats in perpetuity. Joint Ventures (JVs) use a partnership based approach to deliver specific bird population and habitat objectives within their geography. Currently, 7 of the 12 JVs that occur in the North American bobwhite range have bobwhites listed as a priority species. This presentation will cover various topics including: 1) the history of JVs in North America; 2) an overview of the variety of models …

Temperature Assessment On A Reclaimed Surface Mine During Northern Bobwhite Breeding Season: Considerations For Habitat Management, Donald M. Yow, Jeremy P. Orange, John J. Morgan, Gary Sprandel, Danna L. Baxley, Eric Williams

National Quail Symposium Proceedings

Ground-level air temperatures were assessed within 4 distinct habitat areas on a managed reclaimed surface mine at Peabody Wildlife Management Area, Kentucky, 26 June–17 July 2015, during the northern bobwhite (Colinus virginianus) brood season. Habitat consisted of disked and nondisked areas of native grass and an invasive species, sericea lespedeza (Lespedeza cuneata). Disked areas offered more open space for bobwhite mobility and experienced higher average temperatures than nondisked sites. Although statistically significant, differences in air temperature between disked and nondisked areas were likely too small to have practical implications for bobwhite habitat management in Kentucky under …

Progress Of The National Bobwhite Conservation Initiative, Donald F. Mckenzie, John J. Morgan, Thomas V. Dailey

National Quail Symposium Proceedings

Northern bobwhites (Colinus virginianus) have declined precipitously over 5 decades because of a decline in habitat, largely a result of agricultural intensification and inadequate management of natural plant succession. In response, quail biologists developed strategic and operational plans, and formed a national partnership of state and federal agencies, bobwhite institutions, non-government organizations, universities and private citizens. The early history of these efforts was reviewed in 2006 at the Sixth National Quail Symposium. Over the past 10 years, exponential growth occurred, including establishment of a home for national bobwhite conservation at the University of Tennessee, and funding from the …

Aligning Natural Resource Conservation, Flood Hazard Mitigation, And Social Vulnerability Remediation In Florida, Juliano Calil, Sarah Newkirk

Journal of Ocean and Coastal Economics

Flooding continues to be the most common and damaging of all natural disasters in the United States. In 2016, twelve individual weather and climate events caused more than $1billion in damages each. During 2016, the U.S. was hit by at least five once-in-1,000 years precipitation events, and severe floods resulted in more than $17 billion in damages. Currently, more than 5.5 million active policies under the National Flood Insurance Program, underwrite more than $1.6 trillion in assets. Since 1978, NFIP has paid out more than $38 billion in claims – nearly 30% was paid to the 1% of properties classified …

Software Development For Home Energy Audits: Reducing Energy Consumption In Harrisonburg Through Technology, Brantley E. Gilbert

Senior Honors Projects, 2010-2019

Fossil fuels play a vital role in our daily lives. Oil, natural gas, and coal powers our cars, heats our homes and water, and are used by power companies to generate the massive amounts of electricity used every day by the United States. However, this reliance on a finite source of energy is not sustainable. Fossil fuels such as these are non-renewable resources whose production will eventually be unable to keep up with the rate of consumption. Furthermore, the extraction of the stored energy in these fuels through combustion releases harmful substances into the environment, including toxins and greenhouse gases …

Understanding The Past, Present, And Future Of Land Conservation In South Carolina, Nicole Berson

Graduate Theses

Urbanization poses a significant challenge for many ecosystems in the United States. However, monitoring its impacts requires extensive data and this lack of up-to-date information makes understanding the impacts of urbanization difficult to assess. One area that has seen tremendous growth is the Interstate 85 (I-85) corridor between Charlotte, NC and Atlanta, GA, which is known as “The Boom Belt.” Unfortunately, due to limited resources from conservation and state agencies, data on land use change and its impacts in this area have not been updated since the early 1990s. To investigate how urbanization is impacting this region, I conducted a …

Understanding Urban Wilds: Nature, Culture, And Management, Ted Randich

Sustainability and Social Justice

Undeveloped natural areas in cities, or urban wilds, are an invaluable resource to urban populations. They provide space for physical activity, mental recovery and relaxation, and nature interaction and learning, among other benefits. Through observation, intercept survey, and interviews, this study explores three urban wilds sites in Worcester, Massachusetts. Current literature covers definitions of what makes nature “natural,” contemporary practices in conservation, and evidence of the benefits listed above. This paper builds on the literature, shedding light on what urban wilds are made up of (nature), how they are used (culture), and how they are sustained through management. A conceptual …

Trap-Neuter-Return Programs And The Importance Of Associated Public Awareness, Nicolette Sliwa

Biology: Student Scholarship & Creative Works

The focus of this paper is to describe a typical Trap-Neuter-Return (TNR) program and highlight the major pros and cons surrounding this somewhat controversial method of managing the overwhelming free-roaming cat population. The effects of the species’ overabundance on the environment and human health are also discussed. Citing studies completed on TNR programs around the globe as well as mathematical models, the effectiveness of this method is compared to other, currently used alternatives. Finally, it has been suggested that the general awareness level a neighborhood possesses about the true goals of TNR programs has a potentially significant impact on the …

Unusual Aerobic Performance At High Temperatures In Juvenile Chinook Salmon, Oncorhynchus Tshawytscha, Jamilynn B. Poletto, Dennis E. Cocherell, Sarah E. Baird, Trinh X. Nguyen, Valentina Cabrera-Stagno, Anthony P. Farrell, Nann A. Fangue

School of Natural Resources: Faculty Publications

Understanding how the current warming trends affect fish populations is crucial for effective conservation and management. To help define suitable thermal habitat for juvenile Chinook salmon, the thermal performance of juvenile Chinook salmon acclimated to either 15 or 19°C was tested across a range of environmentally relevant acute temperature changes (from 12 to 26°C). Swim tunnel respirometers were used to measure routine oxygen uptake as a measure of routine metabolic rate (RMR) and oxygen uptake when swimming maximally as a measure of maximal metabolic rate (MMR) at each test temperature. We estimated absolute aerobic scope (AAS = MMR − RMR), …

A Descriptive Analysis Of Regal Fritillary (Speyeria Idalia) Habitat Utilizing Biological Monitoring Data Along The Big Bend Of The Platte River, Ne, Andrew J. Caven, Kelsey C. King, Joshua D. Wiese, Emma M. Brinley Buckley

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Speyeria idalia populations have declined as much as 95 percent over the last three decades. Here we critically evaluate prairie habitat components along the Platte River in central Nebraska that S. idalia populations require in an effort to better inform conservation efforts. We utilized S. idalia count data from biological monitoring transects where vegetation, soils, land management, and flooding frequency data were also collected to describe the habitat constituents associated with S. idalia presence. We utilize comparative statistics, Pearson’s correlation analysis, and random forest analysis to model S. idalia habitat on land owned and managed by a small conservation NGO. …
