Coral Reefs. These amazing organisms play a huge role in the lives of millions of people, as well as on countless species of animals and plants, in more ways than one might imagine. They serve to protect coastlines from major storms, they provide shelter to countless species of fish and aquatic vegetation, and they help to bolster economies in areas surrounding them as tourist attractions. Is coral incredible? Yes. Is it invincible? No. A study conducted by Bernhard Riegl and Sam Purkis serves to demonstrate the fragility of these coral reefs, not only studied, but also, coral reefs around the world; as well as to call into question the actions of society and their effects on the environment. The study analyzes the effects that four back-to-back mass mortality events had on the population dynamics of 4 widespread species of coral; Acropora downingi, Porites harrisoni, Dipsastrea pallida, Cyphastrea micropthalma, respectively. As a whole, Riegl and Purkis’ study serves to bring to light the issue of changing coral dynamics as a result of climate change, to the scientific community.
Over the course of their research, Riegl and Purkis employed a variety of techniques to observe changes in coral populations over the course of the mass mortality events that took place within their population. These tests were conducted in the SE Arabian/Persian Gulf, in Ras Ghanada in Eastern Abu Dhabi, one of the warmest portions of ocean on the planet, and were specifically studying 5 species of coral . These measures consisted of devising 4 (initially 5, however, 4 and 5 were consolidated due to the rarity of portions of coral that reached a size large enough to be separate from those in group 4) different sizing groups to allow for more thorough a...

... effort or decrease in luxury that is perceived to come from having a green thumb. These stigmas perpetuate a cycle that continues on, threatening the lives of countless species, as well as the long-term survivability of human beings on Earth.
The studies of Riegl and Purkis served to provide much more than simply a lot into the scientific deterioration of coral reefs. In addition to providing great insight into the things such as bleaching and other diseases that cause coral to die out, this research served to show some of the adverse effects of climate change on the environment. The data and tables serve as a model demonstrating the effects that climate change can have on our ecosystem by quantifying, then displaying the effects themselves, making it easier to understand why these phenomena occurs within coral populations and how it pertains to the world around us.

Essay on Coral Reefs And The Dynamics Of Them

- Dr. Riegl and Dr. Purkis complete this experiment related to coral reefs and the dynamics of them in a mass mortality event. In the Middle East where this experiment was done over the course of four years from 2009-2012, and took into account four different species and how they responded to these cataclysmic events. The event that took place in 2009 was a series of diseases that severely impacted the coral dynamics, while the next three years of the experiment, mass mortality was caused by bleaching and other diseases....   [tags: Coral reef, Coral, Ecosystem, Algae]

Coral Bleaching : Causes And Effects Essays

- Coral bleaching can be caused when coral is stressed by many things including pollution, overexposure to sunlight and extreme low tides however, it primarily occurs when corals are stressed due to unusually high sea temperatures (National Oceanic and Atmospheric Administration, 2015). Unusually high temperatures cause coral 's colourful, symbiotic algae (zooxanthellae) to separate from the coral leaving it to appear white (De 'ath, Fabricius, Sweatman & Puotinen, 2012; Baker, Glynn & Riegl, 2008)....   [tags: Coral reef, Coral, Climate change]

The Value Of Coral Reefs Essay

- Value of Coral Reefs The variety of biodiversity present on coral reefs is greater than in any other marine ecosystem despite reefs being present on only 0.1% of the world’s oceans. Of the 33 phyla present on Earth, 32 of them can be found on coral reefs and 15 of the 32 are found exclusively in coral reef ecosystems (Bryant et al., 1998). These ecosystems represent essential spawning, nursery, and feeding grounds for over 25% of total marine biodiversity (Bryant et al., 1998). Twelve percent of all marine fisheries are directly or indirectly reliant on coral reef ecosystems in addition to over 4,000 species of fish, an abundance of macrofauna (e.g....   [tags: Coral reef, Coral, Ecosystem, Algae]

Coral And The Great Barrier Reef Essay

- A natural wonder, the Great Barrier Reef is home to an abundance of marine life. It is a breeding area for humpback whales, migrating from the Antarctic, and is the domain for endangered species including the Dugong and large Green Sea Turtle (The Great Barrier Reef, par. 1). This natural beauty is a complex structure built mainly out of calcium skeletons that are laid down by hard corals (Great Barrier Reef Marine Park Authority, par. 3). However, it is close to extinction. Brain Clark Howard, in his article titled “Corals are Dying on the Great Barrier Reef,” published by National Geographic reports, “scientists have discovered an unprecedented die-off in the world’s largest reef, the Grea...   [tags: Coral reef, Coral, Great Barrier Reef, Ocean]

Global Warming And Its Effects On The Coral Reefs Essay

- Climate change is predicted to become a major threat to biodiversity in the 21st century,
but accurate predictions and effective solutions have proved difficult to formulate(Terence P et al., 2011). Warmer and more acidic conditions inhibit coral calcification, carbonate precipitation, and submarine cementation; These effects are expected to reduce long-term rates of reef framework construction(Lauren et al., 2012).As global warming gradually becoming severe, it’s effects on the coral reefs also leads a critical concern about the diversity and quantity of coral reefs in Great Barrier....   [tags: Coral reef, Coral, Great Barrier Reef]

Essay about The Coral Reefs

- There are many diverse plant communities in south Florida, but some of the most enigmatic plant communities are found underwater. The coral reefs are a landscape that many people have not had much contact with. Much like how only the elite, travelling, or industrial entities have a view from the ocean, the coral reefs are only viewed by the adventurous or lucky few that can reach their subterranean habitat. But just because they are not seen from the surface does not mean they should be hard to get to....   [tags: Coral reef, Coral, Primary production, Algae]
