Genetic Population Dynamics Of The Critically Endangered Scalloped Hammerhead Shark (Sphyrna Lewini) In The Eastern Tropical Pacific Ocean, Sydney P. Harned Aug 2021

Genetic Population Dynamics Of The Critically Endangered Scalloped Hammerhead Shark (Sphyrna Lewini) In The Eastern Tropical Pacific Ocean, Sydney P. Harned

All HCAS Student Capstones, Theses, and Dissertations

The scalloped hammerhead shark, Sphyrna lewini, is a Critically Endangered, migratory species known for its tendency to form large aggregations of mostly adult females, especially in the heavily-fished Eastern Tropical Pacific (ETP) Ocean. This species forms iconic, visually spectacular, seasonal aggregations in the northern Galápagos Islands, and it is hypothesized based on telemetry studies that pregnant females from these aggregations migrate to mainland coastal nurseries for parturition. This study investigated the population genetic dynamics of the scalloped hammerhead across most of its coastal and offshore distribution (Mexico to Ecuador) in the ETP, focusing on young-of-the-year animals sampled from nursery …


Toxicology Of Chemical Stress To Monarch Butterflies (Danaus Plexippus L.), Annie Krueger Aug 2021

Toxicology Of Chemical Stress To Monarch Butterflies (Danaus Plexippus L.), Annie Krueger

Department of Entomology: Dissertations, Theses, and Student Research

Monarch butterfly (Danaus plexippus L.) population declines have caught the attention of the country and prompted nationwide conservation initiatives. The United States Fish and Wildlife Service has identified insecticide exposure and loss of milkweed (Asclepias spp.) reproductive habitat as primary threats to the monarch. In the Midwestern US, milkweed largely occurs around cropland borders where there may be a spatial and temporal overlap of monarch larvae, insecticide usage, and fertilizer applications. In this study, the acute toxicity and sub-lethal effects on growth and diet consumption of two commonly used pyrethroid insecticides, bifenthrin and beta-cyfluthrin, were characterized …


Litigating For Legality: Nature Conservation, Commercial Fisheries And Disputed Territoriality In Ukraine’S Danube Delta, Tanya Richardson Aug 2021

Litigating For Legality: Nature Conservation, Commercial Fisheries And Disputed Territoriality In Ukraine’S Danube Delta, Tanya Richardson

Anthropology Faculty Publications

Between 2014 and 2016 Ukraine’s Danube Biosphere Reserve (DBR) administrators devoted extensive time to lawsuits in which they defended the legality of commercial fisheries in reserve territory. Two cases are discussed in order to examine what impact litigation had and why administrators pursued litigation when dominant accounts of law in Ukraine suggest that avoiding the courts might be a more likely response. It analyzes court documents and interviews gathered during anthropological research about nature conservation in the Danube Delta by combining insights from political ecology, agrarian studies, and socio-legal scholarship on Ukraine. Even though administrators lost their cases and had …

Identifying The Dominant Ecological Worldviews Of Community Leaders And The Influences These Have In Managing Conservation Areas In Ghana, Nana Owusu-Ansah Jun 2021

Identifying The Dominant Ecological Worldviews Of Community Leaders And The Influences These Have In Managing Conservation Areas In Ghana, Nana Owusu-Ansah

Journal of Management for Global Sustainability

This study was set on the premise of a research question that sought to identify the dominant ecological worldviews of Community Resources Management Area (CREMA) leaders and the influences these have on the management prescriptions of their conservation areas. The relevance of the question was to identify whether the CREMA leaders subscribed to an eco-centric or an anthropocentric worldview which could have direct consequences for the control of resource levels of utilization after the devolution of authority. A phenomenological approach was thus applied to collect data from nine selected conservation leaders from three different CREMAs. Their ecological worldviews were found …

The Big Picture: Consolidating National Government And Cites Records Of Animal Trade In The Philippines From 1975 To 2019, Ronald Allan L. Cruz, Catherine Genevieve B. Lagunzad Apr 2021

The Big Picture: Consolidating National Government And Cites Records Of Animal Trade In The Philippines From 1975 To 2019, Ronald Allan L. Cruz, Catherine Genevieve B. Lagunzad

Biology Faculty Publications

The Philippines has exceptionally high biodiversity but is also a hotspot. It is a recognized source; destination; and transit point for the global wildlife trade; which drives biodiversity loss. There is an abundance of data from the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) on the Philippines; but this data has not been assessed for historical trends. Confiscation data reflecting the illegal trade is scarcer; coming from recent (2008 onward) records of the Department of Environment and Natural Resources ___ Biodiversity Management Bureau (DENR-BMB) and the Palawan Council for Sustainable Development (PCSD). CITES data …

Reimagining The Duck Stamp, Hunting Licensure And Public Land Preservation, Alec Wayne Boyd-Devine Apr 2021

Reimagining The Duck Stamp, Hunting Licensure And Public Land Preservation, Alec Wayne Boyd-Devine

Masters Theses & Specialist Projects

The American Migratory Bird Hunting and Conservation Stamp, or Duck Stamp, is a form of licensure issued by the Federal Government for waterfowl hunters. Why do physical stamps act as licensure to hunt waterfowl on both public and private land in the United States? How did the stamp become the key that grants access to resources that supposedly should be owned by the public? The duck stamp has been well-documented in conservation communities as a resource which has made significant positive impacts on the environment. The increase of anti-hunting sentiments in our society combined with fewer hunters per capita may …

Solutions Human Centered Approach To Conservation, Illustration Department, History, Philosophy, + The Social Sciences Department

Illustration Course Work & Materials

"These essays were were written and illustrated by students at the Rhode Island school of Design in February, 2021. Their perspectives are entirely personal and reflect their efforts within a 5.5-week fused studio/seminar course that was centered on the Sixth Mass Extinction and how biodiversity is changing because of humans. Discovering that science communication is more than delivering just the facts, students were invited to research a topic of personal interest that is relevant to human impacts on biodiversity. Through analysis of data and other scientific information, each sought to synthesize their research and opinions on their topic through a …


Conserving America: A History Of America’S Conservation Movement And The Establishment Of The National Park Service, Jack Jones Jan 2021

Conserving America: A History Of America’S Conservation Movement And The Establishment Of The National Park Service, Jack Jones

Senior Independent Study Theses

The National Park Service (NPS) is the conservation agency recognized around the world for its efforts to preserve areas of beauty within America. This I.S seeks to answer the question of how and why the NPS developed? There are several factors to consider. To begin at the end of the nineteenth century the first National Park efforts at both Yellowstone and Yosemite mark the beginning of a larger conservation movement within America. Both of these parks serve as models for how conservationists and the government will move forward in creating more parks and conservation agencies. They also came out of …


Conservation, Sharks, And The Tragedy Of The Commons: Achieving Human-Nature Holism, Fiona Melady Jan 2021

Conservation, Sharks, And The Tragedy Of The Commons: Achieving Human-Nature Holism, Fiona Melady

Regis University Student Publications (comprehensive collection)

Environmental ethics originates from the idea that the relationship between humans and non-human nature should be considered morally. How we deal with environmental issues depends on our perception of human-environment relationships. Many view nature as something separate from themselves to own, use, and exploit for human benefit; others view nature as something of which humans are a part and having an intrinsic value aside from practicality or usefulness. This thesis examines human-environment relationships through anthropocentrism and ecocentrism and advocates for balancing the two perspectives. Furthermore, this thesis examines the importance of marine environmental conservation, particularly sharks, and how transitioning towards …

The Western Indian Ocean (WIO) is comprised of productive and highly diverse marine ecosystems that are rich sources of food security, livelihoods, and natural wonder. The ecological services that species provide are vital to the productivity of these ecosystems and healthy biodiversity is essential for the continued support of economies and local users. The stability of these valuable resources, however, is being eroded by growing threats to marine life from overexploitation, habitat degradation and climate change, all of which are causing serious reductions in marine ecosystem services and the ability of these ecosystems to support human communities. Quantifying the impacts …
