Primnoa Pacifica Reproduction In Shallow Versus Deep Habitats Of Glacier Bay National Park And Preserve, Alaska, Ciara N. Larence

Honors College

Primnoa pacifica is a species of deep-sea cold-water coral that can be found in Glacier Bay National Park and Preserve in Alaska. These colonies are important to their ecosystem as they provide habitat for other species living in this area. One thing that makes P. pacifica important to study is that the species displays deep-water emergence. This is a phenomenon where species normally found in deep waters can exist in shallower waters, allowing easier access for research. The purpose of this thesis was to determine if depth effects the reproduction of male P. pacifica colonies. Two colonies from deep depths …

Effects Of Glacial Stressors On Sperm Maturation In Colonies Of The Red Tree Coral, Primnoa Pacifica, Joshua Lynn

Honors College

The red tree coral, Primnoa pacifica, is a large, colony forming species of cold- water coral which is often an important habitat for many commercially important species of fish and crab. This keystone species is long lived and found at much shallower depths in the fjords of Glacier Bay National Park (GBNP) than elsewhere in the northern Pacific Ocean because of the phenomenon known as deep-water emergence. Due to their proximity to tidewater glaciers in GBNP, corals likely have to endure glacial stressors such as freshwater runoff and sedimentation that is not typical of populations in deeper water, which …

The Controversy Of Sunscreen Ingredients: Examining The Relationship Between Oxybenzone And Butylparaben On Stylophorum Pistillata, Brian K. Lee, Natalia Corvalan, Jae Z. Saraum

Exigence

Abstract

The basis of this proposal is to understand the relationship between select UV filters and coral bleaching and provide a framework for additional research. Coral reefs are home to a diversity of marine life and are keystones to major coastal economies around the world. Oxybenzone and butylparaben are major ingredients found in sunscreen that induces coral bleaching to major coral reefs. To alleviate the negative effects, this proposal will attempt to better understand how oxybenzone and butylparaben facilitates coral bleaching and develop an effective and environmentally fair sunscreen. The research proposed will be funded by donors to cover research, …

Phenomenological And Molecular Basis Of The Cnidarian Immune System, Tanya Brown

FIU Electronic Theses and Dissertations

Coral reefs are one of the most diverse ecosystems on the planet due partially to the habitat structure provided by corals. Corals are long lived organisms that can live for hundreds of years and as a result growth of many species is very slow. As a result of this, recovery of corals from disease outbreaks is very slow and difficult and therefore the ecosystem is deteriorating rapidly. Due to this increase in disease and its detrimental effect on coral reefs, it has become imperative to study how corals respond to disease outbreaks. The response of the coral to pathogens is …

Coral-Fish Dynamics And Interactions: A Case Study Of Grand Cayman, Eileen Shea Davis

Lawrence University Honors Projects

To better understand the ecological interactions of coral reefs, it is important to understand the mechanisms that control the distribution and abundance of reef-building corals as well as the mechanisms that control the diversity and abundance of the fish community that inhabits these reef habitats. The purpose of this study was to identify specific coral-fish interactions among the reefs of Grand Cayman in order to gain insight into the biological effects of fish on the assemblage of hard corals. Using data collected by the Lawrence University Marine Program (LUMP), a number of exploratory statistical analyses were run in order to …
