Fish Use Of Largely Unexplored Sub-Tidal Habitats In The Hinchinbrook Channel Estuary, Queensland, Alexandra Parisien
Fish Use Of Largely Unexplored Sub-Tidal Habitats In The Hinchinbrook Channel Estuary, Queensland, Alexandra Parisien
Independent Study Project (ISP) Collection
This study examines the use of sub-tidal open-bottom, rocky, and seagreass habitats by the Siganus genus (herbivores), Gerres genus (benthivores), and planktivores in the Hinchinbrook Channel Estuary in Queensland, Australia. The Hinchinbrook Channel Estuary, a tropical estuary cutting between Hinchinbrook Island and the Australian mainland, is surrounded primarily by mangroves. Its sub-tidal habitats are largely unexplored due to factors such as low visibility and the presence of estuarine crocodiles. In this study, I reviewed 699 underwater videos collected by James Cook University PhD candidate Michael Bradley in order to analyze feeding and movement behavior of pre-identified fish.
The results of …
Examining Predation As A Possible Means Of Controlling Crown-Of- Thorns Starfish (Acanthaster Planci) Outbreaks On Reefs Around Lizard Island, Australia, Amanda Chan
Independent Study Project (ISP) Collection
Since the world’s coral reefs are currently threatened by a variety of different natural and anthropogenic factors, research on protecting coral reefs is pivotal to protect these diverse ecosystems. However, only Indo-Pacific reefs such as the Great Barrier Reef are dying due to a corallivorous echinoderm threat known as the Crown-of-Thorns Starfish (Acanthaster planci). A. planci is a starfish which feeds on coral tissue and can quickly reduce coral cover on a reef during an outbreak. Although scientists are still unsure as to what causes these outbreaks, one suggestion is the predator-removal theory. The predator removal-theory states that major predators …
A Case Study Of Rhincodon Typus Scarring In Ningaloo Reef: An Assessment Of The Current Scarring Classification System, Laura Korman
A Case Study Of Rhincodon Typus Scarring In Ningaloo Reef: An Assessment Of The Current Scarring Classification System, Laura Korman
Independent Study Project (ISP) Collection
Rhincodon typus are the largest fish in the sea, but little is understood about this elusive species. They are known to annually aggregate in Ningaloo Reef, Western Australia—the location of this study. In order to better understand this species, scarring was observed on a subset of the population that aggregates in Ningaloo Reef. In addition, the scarring classification system was examined to determine if it is the most effective classification system. R. typus were observed, and photographed from April 9th-April 25th, 2014. These photos were then used for identification and scarring classification purposes. The analysis of the scars on R. …
Advocacy For Marine Management: Contributions To A Policy Advocacy Initiative In The Maldives, Neal Collins
Advocacy For Marine Management: Contributions To A Policy Advocacy Initiative In The Maldives, Neal Collins
Capstone Collection
On June 5, 2009 a 42-‐km2 area of coral reef situated in the Alif Dhaalu (South Ari) atoll of the Republic of Maldives was designated the South Ari Atoll Marine Protected Area (S.A. MPA) due to a globally significant whale shark aggregation site. The whale shark is notorious for its gargantuan size and docile nature, which has led to a burgeoning tourist industry that gives people the opportunity to swim with the gentle giants in tropical sites such as the Maldives. The S.A. MPA receives tens of thousands of visitors a year that engage in whale shark excursions, however, there …
Marine Turtle Health Assessment And Aquarium Suitability: Uzi Island, Zanzibar, Olivia “Warda” Crane
Marine Turtle Health Assessment And Aquarium Suitability: Uzi Island, Zanzibar, Olivia “Warda” Crane
Independent Study Project (ISP) Collection
This study assessed the health of the marine turtles in the aquarium on Uzi Island. Health evaluations of each turtle included size, eating habit, and physical abnormalities. Behaviorally the sea turtles were observed at two different time periods multiple times. Results were compared to research on wild sea turtles. The conditions of the aquarium were evaluated for water quality and holding capacity. The water temperature, pH, and salinity levels were tested to assess the water quality. The results showed that the overall health of the sea turtles were positive from the normal activities and few abnormalities. The overall aquarium conditions …
Bioremediation Mariculture In Zanzibar, Tanzania: A Viability Assessment Of Using Bath Sponge And Pearl Oyster Farms To Filter Highly Olluted Waters In The Zanzibar Channel, Hayley Oakland
Independent Study Project (ISP) Collection
Bioremediation of polluted water off the coastline of the urban center of Zanzibar—Stone Town, Unguja—was assessed for implementation feasibility through bath sponge and pearl oyster mariculture. A vast research base of the city’s coastal area exists, including the pollution concentrations at various locations, the ramifications of this pollution on the fringing ecosystems, and the relevant water circulation system of eddies and passageways produced by the north flowing East African Counter Current. In following the experimental examples of bioremediation projects around the world, this study tested facets of the filtration abilities of marine sponges and oysters. Both organisms suggested strong pollution …
Assessment Of Genetic Connectivity And Potential Management Plans For The Coral Reef Ecosystems Of Guna Yala, Panama, Molly Mcentee
Assessment Of Genetic Connectivity And Potential Management Plans For The Coral Reef Ecosystems Of Guna Yala, Panama, Molly Mcentee
Independent Study Project (ISP) Collection
Genetic connectivity between three populations of the common reef sea urchin, Echinometra lucunter located in fringing reefs off the islands of Ukuptupu, Wichupwala and Porvenir in western Guna Yala was analyzed to give insight into population distribution and the most effective conservation management plans for the area. The reefs of Guna Yala are facing many threats on a global or regional scale including global warming, ocean acidification, sea level rise, disease and severe storms. On a local level, increasing stress is being placed on these reef ecosystems from human activity including coral mining, overfishing, and pollution. In order to prevent …
Exploring Marine Conservation Efforts In Tasmania: An Internship With Ocean Planet, Lauren Markram
Exploring Marine Conservation Efforts In Tasmania: An Internship With Ocean Planet, Lauren Markram
Independent Study Project (ISP) Collection
I chose to conduct a dual internship with Environment Tasmania and Ocean Planet. Although I was located in the ET office and conducted participant observation within that environment, I specifically worked on the Ocean Planet campaign to promote marine conservation efforts throughout Tasmania. I was drawn to this internship because the oceans are often disregarded within the environmental movement despite the fact that they are the key to life on earth and are in a degraded state. Further, Tasmania’s marine environment is utterly unique, with ninety percent of its marine life found nowhere else on earth. Despite the magnificent biodiversity …
