...Coral reefs are one of the biological cornerstones of the ocean and are fundamental to many marine ecosystems worldwide. Whilst they have countless uses to socioeconomic and tourism sectors globally, their role in the biological sense is of far greater value. By looking at their importance to the biology of the oceans, a greater understanding of the level in which they need to be protected can be formed. One of their key characteristics is their ability to provide shelter and protection to countless marine organisms. This is done so efficiently that entire ecosystems form solely around coral reefs and the habitats they create. These reefs also act as a vital buffer for waves and strong ocean conditions. By dissipating the wave energy, they...

...Coral reefs occupy only 0.2% of the ocean floor, yet they are the most biologically diverse marine ecosystems known today, and support over 25% of all marine organisms (Yip). Due to the massive amount of marine species that populate coral reef habitats, maintaining healthy reefs is crucial for the continuation of marine biodiversity. In past years, the increase of mortality rates in coral has been caused by a number of factors, including wide-spread stress and disease. In the Indo-Pacific, coral reefs have been declining at a rate of approximately 2% per year for the last 20 years (Yip). Coral reef fish biodiversity is crucial for the sustainability of the coral reef ecosystem, as well as for the ability of the coral reefs to provide services...

...Coral reef's are one of the most diverse ecosystems in the world, inhabiting around 25% of all marine species; 4000 of which are fish and another 800 are hard coral (Reaka-Kudla, 1997). Many different factors by both human and natural causes propose threats to the coral reef's. Some of which, if carried on, could mean that the coral reef's will subside. Coral reef's are a major habitat for marine organisms. But if their population declined, this wouldn't just affect different species that live there, it would also affect humans as well. Many different species of fish live in the reef's that humans live off so if overfishing continues in the coral reef's then humans will have to find an alternative food source or try fishing elsewhere. However...

...Department of Biology Spring 2018 BY-445 Background Coral reefs are one of nature’s most diverse ecosystems. The variation in organisms and plant life is what drives many scientists to understand how something so unique can occur. Because coral reefs are so diverse, they help the environment they inhabit in various ways. Coral reefs are biologically diverse and economically important to the ecosystems of the planet. The reason for this importance to the ecosystems is that it provides services that are essential to human life and industries through fisheries, coastal protection, building materials, new biochemical compounds,...

...The first major threat to coral reefs is global warming or climate change. The warming of the oceans is detrimental for coral reefs because they are very particular about what water temperature they live in. Also the warming of the oceans causes glacier to melt, thus causing rising seas. " The Intergovernmental Panel on Climate Change has found that sea level is rising at a rate of .12 inches per year—60 percent faster than the .08 inches per year it predicted in 2007" (Global Reef Threats). Rising seas causes coral reefs to be deeper in the ocean. As something gets further away from the surface it common sense that it will receive less light. This will cause the coral reefs to grow slower. This is a problem considering some coral reefs already...

...LIVING COASTAL RESOURCES OF THE ASEAN REGIONAND DATA REQUIREMENTS FOR THEIR MANAGEMENT SIGNIFICANCE OF LIVING COASTAL RESOURCES Living coastal resources are found within major coastal ecosystems consisting of coral reefs, mangroves, seagrass beds, benthic systems, and estuaries or lagoons. Coastal ecosystems, particularly estuaries and inshore marine waters have the highest rate of primary production as compared to terrestrial and oceanic regions. Daily gross production rate in terms of grams of dry organic matter per square metre area for the narrow coastal band ranges from 10 to 25, with all other regions having substantially lower values (2). The coastal band conveniently thought of as the transition area between land and sea, holdsthis great diversity of ecosystems, each characterized by its own unique ecological feature. Conditions here may be harsh with wide fluctuations in temperature and salinity, but because of the abundance of food supply, these areas can and do support a high diversity of species which have become efficiently adapted to the widely fluctuating environmental conditions. These ecosystems remain productive because of tidal action which circulates food and nutrients rapidly and efficiently and at the same time washes away waste materials. They also serve as efficient nutrient traps of the continuous nutrient input washed down from land. Within these ecosystems, the autotrophic and heterotrophic layers are maintained in close contact so that energy transfer...

Bermas harmful effects of chemical changes are: -acid rain -rust -chemicals in an anti spot cream reacting with a silver necklace, turning it black -exhaust fumes -spoilage of foods -chemical fertilizers 1. Global Warming Cause: Carbon dioxide emissions from fossil fuel burning power plants Our ever increasing addiction to electricity from coal burning power plants releases enormous amounts of carbon dioxide into the atmosphere. 40% of U.S. CO2 emissions come from electricity production, and burning coal accounts for 93% of emissions from the electric utility industry [EPA, pg. 10]. Every day, more electric gadgets flood the market, and without widespread alternative energy sources, we are highly dependent on burning coal for our personal and commercial electrical supply. 2. Global Warming Cause: Carbon dioxide emissions from burning gasoline for transportation Our modern car culture and appetite for globally sourced goods is responsible for about 33% of emissions in the U.S. [EPA pg. 8] With our population growing at an alarming rate, the demand for more cars and consumer goods means that we are increasing the use of fossil fuels for transportation and manufacturing. Our consumption is outpacing our discoveries of ways to mitigate the effects, with no end in sight to our massive consumer culture. 3. Global Warming Cause: Methane emissions from animals, agriculture such as rice paddies, and from Arctic seabeds Methane is another extremely...

...Northwestern University, Field Museum, Shedd Aquarium Abstract Coral samples were obtained from Shedd Aquarium to investigate the symbiotic relationship between the corals and their zooxanthellae under environmental stress. The zooxanthellae DNA were extracted, amplified, and sequenced. The sequences were then analyzed using Sequencher 5.0 and BioEdit where they were aligned individually and then against other sequences found in previous literature research. The aligned sequences were run in Genbank using the BLAST function to identify the zooxanthellae at the subclade level. Further research into current literature was done with the best matched subclades to our sequences to further investigate the thermal resilience of the zooxanthellae. It was found that thylakoid membrane lipid compositions as well as lipid energy reserves are correlated to bleaching susceptibility. Clade D symbionts have higher lipid energy reserves, allotting for more thermal resilience in comparison to clade C as well as increased abundances in D symbiont types among reefs after bleaching events. Bleaching susceptibility was also found to have variation within clades. More research is needed to fully understand the coral-zooxanthellae relationship and acclimatization under stress. Introduction Coral reefs harbor over a fourth of all marine species and therefore are one of the most biologically diverse systems of the oceans (Gills, 2010). The coral community is comprised of a collection of biological communities...

Next, I would like to thank my dear family for their generous, unwavering support and encouragement. Finally, I would like to thank the Student International Discussion Group and the Environmental Internship Fund at the Nicholas School of the Environment and Earth Sciences at Duke University for funding my research. -2- ABSTRACT In the United Arab Emirates, Dubai is building three colossal artificial islands— each in the shape of a palm tree—in the Arabian Gulf. This has prompted several other Gulf countries to construct artificial islands. To determine the impacts of the first of these Palm Islands, The Palm Jumeirah, I traveled to Dubai and interviewed governmental agencies, environmental groups, and the developer’s environmental scientists. I analyzed the island’s impacts on marine wildlife as well as the developer’s mitigation efforts and the developer’s compliance with the relevant environmental laws. The Palm Jumeirah has buried and asphyxiated wildlife, increased turbidity, and changed...

...Brandon Parezo Environmental Science Research Paper November 23rd, 2011 Maldives The country of Maldives is officially known as the Republic of Maldives, or as many people know of it as the Maldive Islands. It is located in the Indian Ocean, island nation, and the way that it is formed is by a double chain of twenty-six atolls (1). An “atoll” is a coral island that surrounds a “lagoon” partially or completely (1). The major surrounding countries near Maldives are Sri Lanka and India, Maldives is about 430 miles from Sri Lanka and about 250 miles from India (1). The major type/s of topography for Maldives is the fact that it is a cluster of around 1,200 small islands (2). One of the islands consists of just the capital, Male, and another one of the islands serves the purpose of the nation’s airport. Besides those two islands, basically every island serves a single purpose. They have an island just to store their fuel, one for their dump yards, 199 of them for population, and 80 islands that consist of major tourist locations (2). For the Maldive Islands there really only one major language spoken, Dhivehi (1). It is a Indo-European language and it spoken by at least 350,000 people on the islands (1). The present-day script that is used on the islands is called Thanna and what is quite interesting about this is that it is written from right to left, unlike us who go from left to right (1). According to the UNESCO (United Nations Educational, Scientific and Cultural...

...implications of the Coral Sea Commonwealth Marine Reserve Management Plan 2014 – 2024 on local communities and the fishing industry justifiable? Next year, on July 1, the world's largest marine reserve will come into effect. The Coral Sea Commonwealth Marine Reserve Management Plan 2014 -2024 is the culmination of more than a decade of campaigning by conservationists, consultation by the Federal Government and vehement opposition by industries and regional communities affected by the decision. On one hand, conservationists believe the nearly one million km² of ocean inside the Australian Exclusive Economic Zone will protect forever the pristine marine ecosystems of the Coral Sea - an iconic statement by the Australian government and its people that it's serious about marine conservation. However, the closure of some of Australia's richest fishing grounds will directly impact on commercial fishers and game charter operators, seafood distributors and wholesalers and other shore-based industries in regional ports such as Cairns. Many of these people claim the outcome has been achieved by the government based on emotive scaremongering campaign driven by a cashed-up environmental lobby without scientific basis. So, who is right? In a community where the local economy has become so reliant on the dominant tourism industry, isn't the marine park sending the right message to the rest of the world about its iconic natural wonders such as the Great Barrier Reef, World Heritage rainforest...
