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 …

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 …
