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 …
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
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 …
