How Does Global Warming Affect Coral Bleaching

Improved Essays
Introduction
Marine invertebrates in the class Anthozoa are known as Corals. These diverse organisms give quite a show in the shallow clear parts of the ocean. Corals live closely together in groups expressing their bright colors that stand out so nicely. Many people consider coral reefs to be very diverse and productive than anything on land. Their skeleton is made out of calcium carbonate protecting them from future encounters with predators. Many more coral polyps then can attach themselves to the coral already there and develops lots of coral reefs grouped together. Photosynthetic algae called zooxanthellae live in the coral’s tissues, protecting them from diseases and providing compounds they need for photosynthesis. Most people may not

However, areas that are most likely to experience coral bleaching are the subtropical and tropical oceans in just a couple of years from now (Yara et al., 2014). Coral reefs are starting to feel the effects of climate change. Indeed, Coral reefs are becoming more and more sensitive to warmer temperatures coming from El Niño (Reaser et al., 2000). There are countless questions that need to be answered about their conditions. Why does global warming lead to coral bleaching? Is it due to the high acidity of the water? Second, Will the increasing amount of carbon in the water cause permanent damage or can it be stopped? Third, what methods can be used to completely end this or slow it …show more content…
The parent becomes large in size and then divides. Stony corals either produce male or female corals; most broadcast spawners release large amounts of sperm and eggs that spread across a certain part of the ocean. Then the eggs and sperm come together to form planktonic larvae called planulae. Predators may come across the corals so they produce tons of planulae and spread as much genetic traits without completely wiping them out. Polyps release the eggs and sperm at the same time due to the fact that females and males cannot actually move to other colonies to reproduce. Once the larvae are in the water they swim to the top of the ocean, the larvae that isn’t not consumed settles back down to the ocean floor attaching to near by hard surfaces. This probably looks like it’s snowing upside down. They then are capable of becoming polyp and begin to grow a coral

    Just north of Key Biscayne in sunny Miami, Virgina Key is a protected barrier Island in the Atlantic ocean. Consisting of 863 acres of land, it was once much larger, extending into the Ft. Lauderdale area. Between 1835 and 1838 hurricanes eroded the beach, creating inlets and dividing the island in two. The other portion became Fisher Island, which sits at the southernmost tip of Miami Beach. Virgina Key was a part of the civil rights movement.…

    We have been able to observe marine organism in the clade Littorinimorpha in the three tides zones high, mid, and low each have their own ecological niche for marine organisms. But there is some marine life that are able to live in patchiness within zones and thrive in more than one. The high intertidal zones are home to marine life that are more tolerant to air, like barnacles (Ricketts et al. 1968). The mid zone includes higher low water and lower low water, which can be indicated by limpets (Ricketts et al. 1968). Last the low zone includes those that are normally uncovered during minus tides (Ricketts et al. 1968).…

    Scientific Validity of “Study links altered brain chemistry, behavioral impairments in fish exposed to elevated CO2” Coral reefs are having a problem with pH levels and they are dying some places around the world right now, because of it. This is not only affecting the coral reefs, but the animals that live in them and survive with them. There is a Scientific Study called “Study links altered brain chemistry, behavioral impairments in fish exposed to elevated CO2” which discusses the behavior and neurological impairments of coral reef fish due to more CO2 and acidic levels of pH. More CO2 causes lower levels of pH and makes it more acidic and very dangerous for fish. Overall this is a poor scientific article, because it has only one good source…

    Coral reefs provide shelter and food for more than 1 million plant and animal species, which is nearly one quarter of all known marine species. This number includes over 4,000 species of fish, 700 species of coral, and thousands of other plant and animal forms of life (Cesar, et al.). A single coral reef at its prime contains tens of thousands of species, housing some of the most dense and diverse communities of vertebrate animals in the world. Unfortunately, with the destruction that they face, very few coral reefs still resemble this condition, with corals and fishes less abundant than they were a few decades ago. Since we didn’t start studying coral reefs until they were already degrading, we aren’t sure about the historical biological baseline…

Producers like Halophila seagrasses, diatoms, cyanobacteria, mangrove trees, zooxanthellae, sea lettuce, caulerpa, dinoflagellates, coccolithophore, and rhodophyta, whether they are green plants or phytoplankton, all adapt to stay in the reef. Adaptations include roots that anchor the organisms into the mud and protective cell walls. Coral is a keystone species of the GBR. Without them, the reef’s biodiversity would dramatically decrease, organisms would lose their homes, & a source of…

    “Runoff carries nutrients sediments, and pollution from land-based sources and deposits them directly onto our reefs.(http://wwf.panda.org/).” Too many nutrients create algal growth creating a decrease in oxygen levels leading to the condition, Eutrophication. Erosion by construction, inland or along coasts, mining, logging and farming increases sediment in rivers. This then ends up in the ocean where it smothers corals by trapping them from the light which is needed to survive. Sedimentation limits the light ability to the corals inhibiting their ability to feed and reproduce.…

    Well-discussed Marissa. You are correct that the ocean acidification implies to the fundamental changes in the chemical balance or chemistry of the Earth’s oceans due to the increased levels of carbon dioxide in the atmosphere caused by burning of fossil fuels (e.g. coal, fuel oil, and natural gas). Ocean acidification is distinct from global climate change; however, the global threats to ecosystems resulting from ocean acidification are theoretically similar as global warming and also, both are caused by carbon dioxide; therefore, several marine biologists have called ocean acidification as “the other CO2 problem” (Doney et al. ,2009; Jurmain p.475). This rapid increase of the CO2 into the atmosphere is being produced by human activities; and…

    I believe this is strong evidence of climate change. Modern humans have been around for around 200,000 years (NHM), only a fraction of 50 million, yet the rate at which ocean acidification has occurred has been the quickest ever recorded. In humans, the blood is around a 7.4 on the pH scale, and even the smallest change, such as 0.2, can cause problems like seizures or death (Bennet). If the smallest change can make a difference in a human, a small change in acidity can make an even bigger difference in smaller organisms. These changes can cause major problems with the small organisms themselves, or they can cause the organism to die off.…

    The water that surrounds the reefs has been warming by 0.9 - 0.12 degrees celsius every ten years. Many reefs in the Coral Triangle have been affected by coral bleaching because of the increase in water temperatures. It is estimated that the Coral Triangle waters will rise by about 1-4 degrees celsius in the years to come. The warmer waters makes it difficult for a range of coral species to survive. Many species would be affected by coral bleaching, causing corals to die and the reefs size to reduce.…

    Increased ocean acidification isn’t the only thing affecting the ocean, but it is very problematic because it erodes aragonite which is a mineral of calcium carbonate. In other words it kills corals and causes the hard exoskeleton to erode. Action needs to be taken to ensure the survival of corals and the creatures that rely on coral reefs to survive. Coral reefs are sources of food for millions of people, but also are sources of medicines. As coral reefs disappear so do the organisms that are mutualistic to it.…

Introduction The most recent research lines are based on understanding wild paralarvae behaviour and prey preferences, refining paralarval nutrition and rearing conditions for O. vulgaris welfare (Iglesias and Fuentes et al., 2014). In the culture of cephalopods, the paralarval life stage is a critical period, especially for octopuses. During this period, the paralarvae must initiate the consumption of a suitable diet to grow, requiring stable conditions for proper development (Iglesias & Fuentes, 2014; Iglesias et al., 2007).…
