Global climate change: there is now sufficient evidence that global climate change, the emission an accumulation of greenhouse gases in the atmosphere, has had multiple effects on coral reefs. (Lesser, 2010) Terrestrial, aquatic and marine ecosystems are all affected by climate change. Coral is a vital part of the Great Barrier Reef ecosystem, without it there would be cascading effects. Coral bleaching is primarily caused by ocean temperature increase, but can also be caused by increased…

The article “Hidden Battles on the Reefs: How Will Coral Reefs Fare in a Changing Ocean?” was written by Tom DeCarlo and was published in Volume 51, Issue 2 of the journal Oceanus in 2016. I accessed the article through the University of West Florida’s library’s website by searching for the Opposing Viewpoints in Context database under the “A-Z Database List.” Once in the database, one can search the title of the article in the search box to locate it. DeCarlo intended this article to be read by…

Emperor Angelfish (Pomacanthus imperator) Introduction: The Emperor Angelfish (Pomacanthus imperator), is a reef-associated marine angelfish and is also called the Imperator Angelfish or Imperial Angelfish. Because of their beautiful color and attractive shape, the species is among the most amazing underwater fish in the Red Sea or in the aquariums. It is possibly the most easily recognized fish in the Red Sea. The display which the species make is marvelous whether done in the wild or in…

clear waters. It has no real soil, being a marine coral ecosystem, but loose carbonate mud covers 135,000 square miles of land. Its biotic factors are animals & plants. It is highly diverse, with 1,500 fish species, hundreds of types of corals, 500 algae species, and many sharks, rays, marine mammals, crustaceans, and echinoderms. Animals like the dugong, butterfly fish, jellyfish, green sea turtle, tiger shark, blue-ringed octopus, krill, cuttlefish, and Crown of Thorns starfish, although of…

keep itself alive then it is not getting much else done which effects the marine life. So what though that it loses its color? Well actually, the bright beautiful colors are because of tiny algae “living in harmony” inside of the coral. So if it loses its color that means the worst has happened and the tiny algae are dying off inside of the color making it hard to provide the coral life. The problem has to start somewhere, and we are only ones to be blamed. It is our fault the temperatures of…

predation upon the African lungfish, the shoebill bird seems the most common predators. In aquarium, lungfishes are known to adapt and accept –depending on their size- a variety of foods including prawn, mussel, fish as well as plant materials such as algae wafers and vegetable…

Many people imagine a sea filled with beautiful color and an abundance of fish when picturing coral reefs, what they do not take into account is destroyed, bleached coral reefs with dying species of fish due to this destruction. This is why we need organizations who will put forth the effort necessary to rebuild and preserve these coral reefs. Many of these organizations lack in their abilities to help the coral reefs as result of the ineffective membership requirements that many of these…

world with an area of 344,400km. Sadly, divers discovered that up to 50% of the reef was dead due to coral bleaching. Coral bleaching is a process that occurs when the water surrounding the coral becomes too warm, resulting in the coral expelling the algae living inside it and then turning completely white. Although coral is able to survive this process, it makes them extremely fragile and increases their chance of morality. Over the last year a total of 12% percent of the world’s coral was…

Intro: Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. They are built by colonies of tiny animals found in marine waters that contain few nutrients and deliver ecosystem services to tourism, fisheries, and shoreline protection. Diadema species are common throughout their range and may be found on reef, sand, and rubble, and sometimes in large aggregations. There are several distinct genotypes of Diadema and this paper will talk…

jellyfish-like animals called polyps, connect together to form colonies. These colonies host algae, that provide corals with food, as well as their vivid color, due to the process of photosynthesis. The combination of environmental disturbances such as global warming, pollution, overfishing, invasive species, overexposure to sunlight, and acidity can cause stress to corals, leading them to expel the symbiotic algae that they need to survive. The process called bleaching, which kills the corals…
