A Computational Profile Of Invasive Lionfish In Belize: A New Insight On A Destructive Species, Joshua E. Balan Jan 2024

A Computational Profile Of Invasive Lionfish In Belize: A New Insight On A Destructive Species, Joshua E. Balan

The Journal of Purdue Undergraduate Research

Since their discovery in the region in 2009, invasive Indonesian-native lionfish have been taking over the Belize Barrier Reef. As a result, populations of local species have dwindled as they are either eaten or outcompeted by the invaders. This has led to devastating losses ecologically and economically; massive industries in the local nations, such as fisheries and tourism, have suffered greatly. Attempting to combat this, local organizations, from nonprofits to ecotourism companies, have been manually spear-hunting them on scuba dives to cull the population. One such company, Reef Conservation Institute (ReefCI), operating out of Tom Owens Caye outside of Placencia, …

A Coupled Model Of Population, Poaching, And Economic Dynamics To Assess Rhino Conservation Through Legal Trade, Henry Doyle, Kylie Champagne, Ditto Rajpal, Grace Seebeck, David J. Gerberry Jan 2024

A Coupled Model Of Population, Poaching, And Economic Dynamics To Assess Rhino Conservation Through Legal Trade, Henry Doyle, Kylie Champagne, Ditto Rajpal, Grace Seebeck, David J. Gerberry

Spora: A Journal of Biomathematics

Rhinoceros populations in Africa are in peril largely due to the high value of their horns and the poaching that ensues. The strategy of legalizing the international trade of rhino horn is receiving increased support among both the people and government officials in Africa. Many in the international conservation community remain opposed to the idea. The legalization strategy is straightforward in theory: legalizing the trade of rhino horn will introduce a large quantity of horn to the market, the increased supply will lead to lower prices for rhino horn, and lower prices will reduce the overall poaching pressure these animals …

Environmental Activism: Pro-Environmental Behavior, Consumerism, And Environmental Justice, Kaden Uribe, April Chapman-Ludwig Feb 2023

Environmental Activism: Pro-Environmental Behavior, Consumerism, And Environmental Justice, Kaden Uribe, April Chapman-Ludwig

DU Undergraduate Research Journal Archive

This literature review examines established research on the concept of pro-environmental behaviors (PEB) and its subsects: activism and consumerism. There are competing opinions regarding the salience of pro-environmental activist behavior. This dichotomy is characterized by the role of social media, which can be simultaneously used for performative identity signaling and as a platform to facilitate global collective activism. The research shows a stark contrast between pro-environmental activism and pro-environmental consumerism, with the former acknowledging historical injustices and addressing the social, economic, and environmental disparities created by neo-liberal policies designed with the purpose of profit extraction at the expense of marginalized …

Rhetorics Of Species Revivalism And Biotechnology – A Roundtable Dialogue, Eva Kasprzycka, Charlotte Wrigley, Adam Searle, Richard Twine Jan 2023

Rhetorics Of Species Revivalism And Biotechnology – A Roundtable Dialogue, Eva Kasprzycka, Charlotte Wrigley, Adam Searle, Richard Twine

Animal Studies Journal

This informal dialogue contextualises and explores contemporary practices of nonhuman animal gene-modification in de-extinction projects. Looking at recent developments in biotechnology’s role in de-extinction sciences and industries, these interdisciplinary scholars scrutinise the neoliberal impetus driving ‘species revivalism’ in the wake of the Capitalocene. Critical examinations of species integrity, cryo-preservation, techno-optimism, rewilding initiatives and projects aimed at restoring extinct animals such as the woolly mammoth and bucardo are used to map some of the necessary restructuring of conservation policies and enterprises that could secure viably sustainable – and just – futures for nonhuman animals at risk of extinction. The authors question …

Factors Influencing Conservation Knowledge: A Survey Of Residents In The United States, Samantha Helgeson, Amanda Fasching, Ashley Kneemueller, Anna Sher May 2022

Factors Influencing Conservation Knowledge: A Survey Of Residents In The United States, Samantha Helgeson, Amanda Fasching, Ashley Kneemueller, Anna Sher

DU Undergraduate Research Journal Archive

Basic principles have been established for visitors of national and state parks, but some visitors may be more aware of conservation practices than others. To understand visitor awareness, this study investigated three factors that influence the general public’s understanding of the Leave No Trace (LNT) conservation ethic: natural areas visitation, state of residence, and media consumption. Each of the factors showed statistically significant impacts on awareness of LNT, supporting our hypotheses that this knowledge will increase with a higher frequency of park visits and media consumption, and that region of residence will also impact LNT knowledge.

Investigating The Effects Of Climate Change On The Phenology Of Achillea Millefolium, Aquilegia Coerulea, And Penstemon Cyanocaulis, Hannah O’Toole, Kailey Hicks, Lisa Long, Jackson Garske, Anna Sher

DU Undergraduate Research Journal Archive

As the effects of climate change are starting to unearth themselves, the impacts can be observed by tracking the patterns of cyclical natural phenomena also known as phenology, and monitoring how they have changed over time. These cycles are at the crux of making ecosystems viable for their local biodiversity, and understanding the ongoing change allows for further understanding of the ecosystem’s change over time. In this study, we look at the ordinal flowering dates of the Achillea millefolium, Aquilegia coerulea, and Penstemon cyanocaulis over the past century. Our data give insight into how warmer temperatures occurring earlier in …

The Pandemic, Climate Change And Farm Subsidies, Allen H. Olson, Edward J. Peterson Sep 2021

The Pandemic, Climate Change And Farm Subsidies, Allen H. Olson, Edward J. Peterson

Journal of Food Law & Policy

Many people believe that once the COVID-19 pandemic has passed, life will return to the way it was. This belief is both unrealistic and dangerous. It is unrealistic because the virus will be around for years if not indefinitely. The timeframe for the worst of the pandemic will depend on our ability to administer effective vaccines worldwide and the public’s willingness to accept continued social distancing in the meantime. The damage done to public health, the economy and individuals is already substantial and will get worse. Recovery will be slow and incomplete. The belief that life will return to the …

Summer To Autumn Population Of Wild Eumaeus Atala On The Ft. Lauderdale Campus Of Nova Southeastern University, Alexandra M. Lens Aug 2021

Summer To Autumn Population Of Wild Eumaeus Atala On The Ft. Lauderdale Campus Of Nova Southeastern University, Alexandra M. Lens

Mako: NSU Undergraduate Student Journal

Eumaeus atala is an endangered tropical butterfly native to the Caribbean and some parts of Florida, USA. Following population reductions primarily due to habitat loss, E. atala populations are now increasing due to conservation efforts of its cycad host plants, especially Zamia integrifolia (coontie). The purpose of this study was to observe, document, and measure the population of wild E. atala on the Ft. Lauderdale, Florida campus of Nova Southeastern University where landscaping use of host plants supports a natural population of E. atala. Forty-four host plants located in two different sites were observed for 14 weeks. One site …

Spatial And Temporal Dynamics Of Human–Wildlife Conflicts In The Kenya Greater Tsavo Ecosystem, Joseph M. Mukeka, Joseph O. Ogutu, Erustus Kanga, Eivin Røskaft Oct 2020

Spatial And Temporal Dynamics Of Human–Wildlife Conflicts In The Kenya Greater Tsavo Ecosystem, Joseph M. Mukeka, Joseph O. Ogutu, Erustus Kanga, Eivin Røskaft

Human–Wildlife Interactions

Biodiversity conservation in developing countries is faced with many and mounting challenges, including increasing human–wildlife conflicts (HWCs). In Africa and other developing countries, increasing HWCs, particularly those adjacent to protected areas, can adversely affect local stakeholder perceptions and support for conservation. We analyzed HWC reports for multiple wildlife species compiled >23 years (1995–2017) from the Greater Tsavo Ecosystem (GTE) in Kenya to determine HWC trends. The GTE is the largest protected area in Kenya, covering 22,681 km2. Overall, 39,022 HWC incidents were reported in 6 GTE regions (i.e., Taveta, Mutomo, Kibwezi, Rombo, Galana, Bachuma). The 5 wildlife species …

Can Farmers And Bats Co-Exist? Farmer Attitudes, Knowledge, And Experiences With Bats In Belize, Hannah G. Shapiro, Adam S. Willcox, Mallory Tate, Emma V. Willcox Jan 2020

Can Farmers And Bats Co-Exist? Farmer Attitudes, Knowledge, And Experiences With Bats In Belize, Hannah G. Shapiro, Adam S. Willcox, Mallory Tate, Emma V. Willcox

Human–Wildlife Interactions

Bats (Chiroptera) are often viewed negatively by the public. Negative public perceptions of bats may hinder efforts to conserve declining populations. In Belize, the presence of vampire bats (Desmodus rotundus and Diphylla ecaudata) exacerbates the potential for conflicts with humans because of the increased rabies transmission risks. To mitigate these risks, the Belize government provides farmers with assistance to trap and remove vampire bats. In June 2018, we surveyed farmers (n = 44) in and adjacent to the Vaca Forest Reserve in Belize to learn more about their attitudes, knowledge, and experiences with bats. This information may …

Like Father, Like Son: Modelling Masculinity For The Ethical Leadership Of President Theodore Roosevelt, Elizabeth Summerfield Jul 2019

Like Father, Like Son: Modelling Masculinity For The Ethical Leadership Of President Theodore Roosevelt, Elizabeth Summerfield

The Journal of Values-Based Leadership

President Theodore Roosevelt is frequently portrayed as a rugged, hypermasculine cowboy. But this depiction ignores the powerful modelling for masculine leadership provided by his father, Theodore Roosevelt senior. A closer examination of the private and public spheres that framed the latter’s life offers another route into understanding the ethical and rational motivations that characterised his progressive Presidency, not least in the area of natural resource management, where his policy innovations were both unprecedented and sustained over time. What emerges is a more complex portrait than the above stereotype, a leader who used his heart, head and experience to think and …

Using Drones To Generate New Data For Conservation Insights, Paul Lorah, Alice Ready, Emma Rinn Aug 2018

Using Drones To Generate New Data For Conservation Insights, Paul Lorah, Alice Ready, Emma Rinn

International Journal of Geospatial and Environmental Research

Human impact on the environment is driving a decline in biodiversity that heightens the need for informed management of conservation lands. Unmanned aerial vehicles (UAVs), also known as drones, are an increasingly cost-effective tool for generating high-quality data used to map landscape features, analyze land cover change and assess the effectiveness of conservation efforts. Traditional sources of remotely sensed data such as satellites and aircraft can be costly, inflexible and unable to detect fine-scale surface variation. This paper explores the advantages (and challenges) of analyzing data collected by drones to generate useful conservation management insights. We focus on three key …

Intensive Land Use And Conservation Planning At The University Of Central Florida, Chelsea R. Piner Jan 2018

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 …

An Evaluation Of Northern Bobwhite Conservation Research: A Call For Large-Scale Studies, Lex J. Gomez, Kelly S. Reyna Nov 2017

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 Nov 2017

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 Nov 2017

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 Nov 2017

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 …
