S Pistillata Lab Report

620 Words3 Pages

I am proposing an experiment to take place in lab, in several different tanks with the exact water chemistry as areas where S. pistillata is currently or used to be abundant, in its native areas. This species has been native to the Gulf of Aden, Red Sea, southern Japan, South China Sea, West Pacific and Central Pacific, and has also been found in parts of Australia. This species can be found as deep as 15 meters and typically thrives in shallow water reef environments. Ex-situ conservation of S. pistillata should first be done in order to have a large enough coral population for testing. A tank will be setup and water from the Red Sea will be used (Tank 1), all tanks will be 3 meters deep and 5 meters wide. The pH of the water will be monitored …show more content…

Due to the fact that this is a fast growing coral, it will be grown for one year to ensure the population grows to be large enough for experimentation. Once enough coral has been grown, six other tanks will be filled with water from the areas mentioned to be native to S. pistillata. The seawater pH and temperature will be monitored, daily, as well as the growth of the S. pistillata. The ensure growth of the coral, the pH will be maintained to represent natural habitat conditions, and the temperature will initially be 26oC, for all tanks, and over time will slowly be increased or decreased to match the temperatures of the corresponding water habitat. The temperature will be adjusted by 0.1oC every week until the ideal water temperature is met for each tank after six months of growth. By allowing the coral to initially grow in altered water pH, it will allow the population to thrive due to being able to adapt to only changing conditions based on OA. Bahr et al., performed a study on the coral species Montipora capitata and came to the conclusion that OW is a more significant threat to coral growth when combined with OA and high irradiance (Bahr et al.,

One major limiting factor could be humans and pollution of the ocean effecting the health of everything in the sea. Temperature is also a huge limiting factor. Coral reefs like the environment to be warm but not too warm, it has to be just right. There is also a need for salt, if salt levels go down in an ocean over a long period of time because of rain or rivers the the coral will die. One last limiting factor is overfishing in the area of the coral reef.

Oceans are peaceful, majestic, and filled with amazing and vibrant color. A lot of the prostown beauty in oceans can be credited to coral reefs. Lately though, natural coral reefs have been dying for various reasons, and some people believe that artificial reefs can help not only the natural reefs, but other surrounding ecosystems in their environment. Various articles use rhetorical techniques in hopes of enhancing their articles about whether or not artificial reefs are helping or harming the oceans. The first article, “Concern Lingers on Success of Artificial Reefs”, was written by Charles Q. Choi, and for Live Science, looks at both the pro and con side of artificial reefs.

This novel focusses on many things relating to our earth but touches deeply on one of our rare wonders in the world, the Great Barrier Reef and how it is being threatened by ocean acidification. In chapter seven, Kolbert is writing about her experiences on a science outpost and is talking about various studies that led up to the discovery that ocean PH levels change how the coral grows. She writes about the results of a study that took place in Arizona: "Coral few fastest at an aragonite saturation state of five, slower at four, and still lower at three. At a level of two, they basically quit building" (Kolbert). What this means is that as the PH levels in the water drop because of CO2 levels, the rate at which the reefs will grow is dramatically decreased to the point that they will stop all together.

Coral reefs are complex ecosystems which each species having an impact on the ecosystem as a whole. For an example an increase of phytoplankton can lead to an increase of Crown of Thorns starfish because their larvae prey on the plankton. Full grown Crown of Thorns starfish eat soft coral and can have a negative impact on coral populations, and the coral cover of that reef.  There are anthropogenic factors that can lead to an increase in the phytoplankton population, such as nutrient runoff. This is another lesson, that humans can have an affect on the health of a coral reef, on both a local and a global scale.

The coral was so weak and brittle, with only a little movement of water it withered away into a fine dust of calcium carbonate shells and skeletons. The acidic water wiped out of all the coral to almost extinction. Bothered by what I saw on this trip I headed up to the boat to report my findings to the unesco. The boat ride returning to the mainland I was shocked to find out how much oxygen I used up in my tank, the coral seemed so much farther down than I expected, the sea level insinuate so much higher. Perturbed by this I knew it was all an effect from climate change and we were all to late to correct the damage

Coral reefs have natural threats of bioeroders who eat through corals calcium carbonate shell, so if corals cannot build their shells faster than bioeroders can eat them, corals will die. This is one major example of how a more acidic ocean will be detrimental. I have consulted articles from the journal Oceanus and from NOAA. Both of these sources publish professionals in the field of marine biology and chemistry. These sources along with general classes I have been taking have helped me and will help me better understand this pressing

“Our globe is under new dramatic environmental pressure: our globe is warming, our ice caps melting, our glaciers receding, our coral is dying, our soils are eroding, our water tables falling, our fisheries are being depleted, our remaining rainforests shrinking. Something is very, very wrong with our eco-system” (Lamm) It may seem very overwhelming on where we should start to help our environment since it seems like such a big task. One small place that we can start is with helping our bleached coral which can help the whole state of our

The destruction of coral reefs is a result of many things, such as pollution, overfishing, ship travel, bad methods of fishing, global warming, and underwater mining. Almost all studies show this decline of these reefs globally, so this decline is happening everywhere (Falk et al). Over the past 50 years, the top 1,000 feet of the ocean have become 0.66º hotter from warming. As water get warmer, it expands, making coral reefs deeper and farther away from the sun they need to thrive (Payment 32). Pollution from trash, factory by products, and cyanide fishing kill many reefs and the fish around them.

Corals are colonial organisms that live on the sea floor, and are essential to the ecosystem. Corals provide a three dimensional habitat for small organisms that live in the ocean, produce food using their symbiotic algae in photosynthesis, and filter the debris out of sea water. Corals are an essential part of the underwater ecosystem off the coast of Australia The corals are also a large source of revenue for Australia, as tourism site that millions visit each year. However, global warming has also led to an increase of seawater temperature.

Ever since the industrial revolution commenced, around one third of the carbon dioxide released by human interference has been absorbed by the ocean, which is one of the reasons of the drastic change in climate as well. Without the ocean absorbing carbon dioxide, the carbon dioxide n the atmosphere would be drastically higher, with possibly increasing the levels of climate change. The point of the research is to see how will the pH affect the organisms in the marine ecosystem and does carbonation affect an organism’s mass and form. Many organisms that are part of the marine food chain are going to be affected by ocean acidification due the levels of acidity deteriorating the calcium carbonate within the animal. It turns out

Ocean acidification is affecting marine life immensely. When our oceans keep acidifying it causes carbonate ions to be less plentiful and these ions are an important part for marine life such as oysters, clams, sea urchins, and corals to get there structures built and maintained such as their shells and coral skeletons(1). Ocean acidification can also affect some fish 's ability to detect predators putting them at a greater risk and causing the entire food web to be in danger(1). The organisms that are having the most trouble adapting to rising acidity is corals because they produce calcium carbonate to make their rocky outer layer that forms coral reefs(2). Coral reefs are the beautiful ecosystems that are booming with life but since the acidity has been rising and so has the overall temperature of the ocean the coral has been bleaching and has not been able to grow well or even stay alive(2).

In this research paper we will explore more about coral reefs and their importance. Coral reefs are communities of living organisms. They are made up of fishes, plants, and many other creatures. They have been around for millions of years: less than the 0.1% of the world’s ocean floor Is covered by coral reefs, however they grow very slowly, from 0.3 cm to 10 cm per year.
