thread_title: No mention of slowest growth on earth

message: I changed the phrase "Coral will also die if the water temperature changes by more than a degree or two and becomes too hot or too cold" because I felt it was misleading. It made it sound like if the current ocean temperature was 25C, then the coral would die if the temperature changed to 24C or 26C. This is not accurate since ocean temperature varies from summer to winter by as much as 5 degrees in the tropics where coral exist. What the statement should convey is that if the normal temperature range is between 20-25C, and if the ocean temperature rises to 26C or drops to 19C for a sustained period of time, then the coral will die. --Uw badgers 17:19, 14 Oct 2004 (UTC)

text: Just a word of warning - corals thrive at the upper limits of their temperature threshold and the limits for thermal bleaching varies significantly depending on the species and geographical location. Frequently corals thrive in 28C waters and only bleach when this threshold is exceeded by a degree. The severity and impact of bleaching is strongly dependant on both temperature and duration of the event, with additional factors such as UV penetration (cloud cover) and tidal regime.

"Coral(s)" is a common name, but common names are associated with specific taxa, and common name article titles that refer to a specific genus or even a species are used throughout Wikipedia. These common names are not really "taxa" either.  The purpose of a taxobox (I think) is to provide taxonomic information down to the level that is reflected in the article.

replies: text: A nervous system isn't what makes an organism an animal. I would imagine that they do have a limited nervous system similar to that of jellyfish, since they are both cnidarians. With that being said, the ability to feel pain isn't exclusive to having a nervous system. It's still not a consensus as to whether or not fish can feel pain. The part that makes them an animal is the necessity to consume other organisms (heterotrophy) for energy. Plants can "make" their own food (autotrophy), animals must consume other plants or animals to get theirs. That, and their development, e.g. having a larval stage, are what make them animals. Their larvae can move, plants cannot. I think I've made it clear, if not just post again here and I'll answer your questions. Esoxidt 19:01, 18 May 2008 (UTC)

message: Found in Environmental effects on coral
"They are so sensitive to their environment that, for example, if someone was to cut themselves on a coral cut it would be of a high risk of infection. This is because the coral will plant itself within the wound and act as a sort of parasite, growing in the cut. It will appear as a rash at first and is highly dangerous."
It is not clear how bearing the ability to cause an infection "equals sensitive to their environment" or is an environmental effect on coral. Perhaps it would be better to create a separate section regarding human and coral interaction and safety?

:It's a matter of growth (expanding a colony or coral head), versus reproducing (creating new separate individuals by releasing gametes). A coral colony will grow and expand by asexual means.

thread_title:  Ohio State University - Class project, critique regarding climate change 

message: 1)This article does a very good job at explaining exactly what Coral reefs are made up of as well as how they reproduce, survive, and function within their respective environment. In the article, titled Coral, there are several sections where the editors get into the taxonomy, eating and reproduction habits, as well as corals natural habitat. When it comes to explaining how coral and coral reefs are used to explain past climates, the article is very thorough in covering the different approaches, but could be more specific about the impacts the world is currently experiencing today. When dealing with data analyses, this article does a very good job of addressing different scientific methods for analyzing how a coral reef relates to past climates, such as geochemistry, oxygen isotope anomalies  "Coral". Wikipedia. 2017-02-12 , and sea surface temperature and salinity  "Coral". Wikipedia. 2017-02-12 . One area the article lacks in data analyses is addressing how climate change is increasing ocean acidification due to increased levels of carbon dioxide  Administration, US Department of Commerce, National Oceanic and Atmospheric. "How does climate change affect coral reefs?". oceanservice.noaa.gov. Retrieved 2017-02-12..
Overall, the assumptions made by this article are fairly accurate. One specific assumption under the Geochemistry header, basically states that climate modeling can get an assist from geochemistry analysis  "Coral". Wikipedia. 2017-02-12 . Climate models can indeed be made more accurate by understanding past climates with help of geochemistry  Stute, Martin; Clement, Amy; Lohmann, Gerrit (2001-09-11). "Global climate models: Past, present, and future". Proceedings of the National Academy of Sciences. 98 (19): 10529–10530. doi:10.1073/pnas.191366098. ISSN 0027-8424. PMC PMC58498Freely accessible Check |pmc= value (help). .. This article, however, does not address the strengths and weaknesses of the proxy method. It only goes as far as to say that the methods may help with piecing together specifics of past climates, but never gets into specifics about real time and past data  "Coral". Wikipedia. 2017-02-12 .
2)I found two peer reviewed articles that dealt with coral reefs as a proxy. The first was titled Redefining thermal regimes to design reserves for coral reefs in the face of climate change and was authored by Iliana Chollett, Susana Enríquez, and Peter J Mumby. This peer reviewed article was not one of the sources cited on the page, but offers some valuable information of how to combat climate changes negative impact on the coral reefs  Chollett, Iliana; Enríquez, Susana; Mumby, Peter J. "Redefining thermal regimes to design reserves for coral reefs in the face of climate change.". PLoS ONE. 9 (10). ISSN 1932-6203. . The second peer reviewed article I found was Exploring errors in paleoclimate proxy reconstructions using Monte Carlo simulations: paleotemperature from mollusk and coral geochemistry authored by M. Carré, J. P. Sachs, J. M. Wallace, and C. Favier. This article used similar geochemistry methods that were described in Coral, but went into much greater detail about the process   Carré, M.; Sachs, J. P.; Wallace, J. M.; Favier, C. (2012-03-01). "Exploring errors in paleoclimate proxy reconstructions using Monte Carlo simulations: paleotemperature from mollusk and coral geochemistry". Climate of the Past. 8 (2). ISSN 1814-9324 . This source was also not cited in under the sources in Coral.
3)In the future, this article could be improved upon in few ways. First, it could go into much greater detail about how changes in the coral reefs and coral patterns show changes in climate, specifically addressing ocean acidification due to increased levels of carbon dioxide. Secondly, the references were overall very credible, but more could be included that point to specific coral reefs and/or coral that are being used as a proxy to give a more clear picture as to how they are being used as a proxy.

thread_title:  Coral Article Critique-Brady Harris, student from Ohio State 

message: While this article does do well with giving a broad overview of the current research on the effects climate change has on corals it gives no description or direct reference to what a proxy is, only someone with previous knowledge as to the definition of a proxy would be able to make the connection that corals are in fact being used as a proxy. To improve this a simple sentence in the first paragraph describing a proxy, and stating that coral is one within climate research, would help people understand. Secondly, simply adding in a diagram or picture of how the growth rings in coral worth similarly to the rings in a tree would add a visual element to possibly describe how this works better. This does cover the idea of checking the data recovered from the proxy (in this case coral) with data from other sources in order to ensure the data is accurate and reliable. The idea that this proxy has a huge strength because it is very useful to get data about the earths atmosphere from before data was being recorded by humans is also touched on. Not many weaknesses of the proxy method are touched on, but if the word itself was to be introduced as recommended it could be linked to the separate proxy article which would go more in depth about the strengths and weaknesses of the overall method. 
The peer reviewed articles used as references within this article are very accurate and have a lot of very good information in regards to what this article is about however all of them are over 10 years old.Lots of new research has since come out with lots of opportunity for new things to be added to this article. For example I found an article published in 2011 titled Projecting Coral Reef Futures Under Global Warming and Ocean Acidification . This article describes in detail what coral shows the previous climate patterns to be and how the coral is being directly effected by global warming and what we expect to see if current rates continue. Pandolfi, John M., et al. “Projecting Coral Reef Futures Under Global Warming and Ocean Acidification.” Science, vol. 333, no. 6041, 2011, pp. 418–422., www.jstor.org/stable/27978279. A second article I found titled Improved Water Quality Can Ameliorate Effects of Climate Change in Corals and is from 2009. This article is not used in this Wikipedia page but discusses the optimal water conditions for coral that allow them to flourish and the current water conditions that are causing them to die. It also describes how by locally managing the water conditions we could perhaps preserve the coral far better then we currently are. Wooldridge, Scott A., and Terence J.

thread_title:  Climate research section critique 

message: (1) This article touches on the use of coal as a proxy by stating that there are rings used to look at incremental dating. This article doesn't do a good job as stating how far back the rings can proxy or what the rings tell us. The article also doesn't give any assumptions. It states that the salinity of the ocean is rising because of coral bleaching, but it leaves out any assumptions about the environment in the past compared to now using rings. The article does not describe the strengths and weaknesses of coral as a proxy. It covers how bleaching and adaptations are working currently but there is no speak of the past climate or how ring contribute to the climate proxy. 
(2)NOAA 2009 http://www.noaanews.noaa.gov/stories2009/20090305_coral.html is used to demonstrate the ocean acidification but it is in the section about coral rings and it does not add any importance to the meat of the section.

message: I'm a student at The Ohio State University and I'm critiquing this article for a class project.
The proxies that I read about in this article show how the coral growth rings show the environmental changes that the corals undergo climate research [64]. It's a great source for geologists to see a yearly change in the corals. I feel that this is strong proxy method due to the heavy yearly analyzing the geologists do. In one of my Earth Science courses at OSU we get to see fossilized coral and it't amazing to see how coral has changed through the different time periods. Current coral and coral from the late permian period have astounding differences. The article also states how microatolls can be dated using radiocarbon dating.
"Fossilized microatolls can also be dated using Radiocarbon dating. Such methods can help to reconstruct Holocene sea levels.[66]", this was referenced from a reliable source that is up to date and found at the bottom in references. Another proxy found "Though coral have large sexually-reproducing populations, their evolution can be slowed by abundant asexual reproduction.[68] Gene flow is variable among coral species.[68]". This article is shown in the references too and is relevant data.
I think this is a great article with a wide variety of pictures, but I do feel more pictures of fossilized corals could be a great addition. Many people are visual learners and seeing a variety of corals throughout time could be beneficial to the reader. Overall, this was a very informative article that gave me knew information about coral life.SS.12 (talk) 03:55, 23 February 2017 (UTC)
thread_title:  Editing for Geography OSU  

message: This article clearly explains the use of coral as a proxy in understanding past climate. In regards to data analysis of coral, the article elaborates on geochemistry; strontium/calcium ratio; oxygen isotopes; and sea surface temperature and salinity. Upon further analysis of the coral (specifically its crystalline structures), each of the above attributes provides data that contributes to climate models. Continuing, the article does not directly mention any assumptions made in using coral as a proxy. However, it does comment on the complexity of coral longevity, reproduction, and evolution. This is an indirect assumption that the coral have stayed in their approximate location. The article discusses how staghorn and elkhorn coral shifted their locations. Therefore, when utilizing the coral for climate modeling an indirect assumption is that the coral specimen have always lived in that particular area. Lastly, the strengths of coral proxies mentioned includes the detailed, large amount of the information they can potentially display about climate and their “stable foundations” for geochemical interpretations of particular living species, such as Porites. A strength the article did not mention was that coral chemistry can indicate heavy rains and floods (NASA 4). Some weaknesses mentioned include their small population and high sensitivity. However, the article does not discuss their limited location (not available worldwide), nor does it discuss potential outside influences such as symbiotic relationships (algae)(NASA 4).

This article list numerous references with centralized focus on climate. Of the peer-reviewed articles that distinctly state climate as the main topic, the oldest peer-reviewed article listed is from 1989 and the most recent is from 2009. A majority of the others are between 1999 and 2005. That said, the one from 2009 is not horribly out of date. However, the others are. There is an article about climate change, coral bleaching, and the future of coral reefs from 1999. This article is approximately eighteen years old, and with all of the developments in ocean research; coral research; and climate change the source is no longer in its prime. Overall, more current sources would allow for an updated perspective and integration of new ideas/concepts.

message: My fellow classmates make great points about the use of corals as a tool for proxy data. I would recommend the expansion and rephrasing of some pieces of information -- for example, "which are colonies whose top is dead and mostly above the water line, but whose perimeter is mostly submerged and alive" seems clunky and not easily understandable. I would change this phrase to, "which are colonies of coral that is mostly submerged in the water, but whose top is dead and extend above the water line."
As for sources, all sources I checked were alive and unbiased. Some sources were from sources that were arguably not peer edited. An additional sources could be ""Climate Close-Up: Coral Reefs."

thread_title:  General Relay of Information in Article 

message: 1. When talking about coral in the climate research section it talks all about components of a proxy without directly stating it. This is a very broad way of stating the information about coral and how it grows to show characteristics as one of the climate proxies. With this in mind it still states the process that the coral will go through to produce this climate record. The section also touches on radiocarbon dating but doesn't include more specific dates or the amount of time coral can go back to show an earlier climate. Aside from the proxies problem above, this section assumes a simple understanding of the material and goes enough in depth to show the meaning of most of the material within.
2. An article that wasn't on cited on the Wikipedia page but informs about coral reef proxies is titled Environmental Records from Great Barrier Reef Corals: Inshore vs. Offshore drivers. This article basis is to show the ability of corals to show what environmental factors impact how they grown and what their structures consist of after these factors. Another article not referred to is titled Low Generation of Lesions produced by coring in Orbicella faveolata.  This article states the problem of taking proxy samples in certain types of coral that can have a lasting impact on how the coral regenerates where the proxy sample was taken from.
3. A way to better the climate research section is to talk about a wide variety of corals that would be detectors of proxies instead of only the one that is stated. Another type of info that could be added is the amount or range that the coral can date back to. The section doesn't do a good job of stating whether this proxy is a short-term or long-term record of how the ocean was and what the composition of the ocean was at that time.

message: Throughout the entire section of Coral (climate) there is no use of the term “proxy” or even “paleoclimatology”.  Instead, the article discusses the changes coral has been forced to undergo due to climate fluctuation over time.  Proxies are “preserved physical characteristics of the environment that can stand in for direct measurements” < https://www.ncdc.noaa.gov/news/what-are-proxy-data>.  Since the atmospheric measures of temperature and CO2 do not go back very far, these physical characteristics give scientists an extension of records that help then analyze the past climate changes, giving them crucial insight into today’s problem. None of this is made clear.  We are given several ways coral adjusts to its environment, but there is little application.  This article would be strengthened by having a variety of people creating it and editing it.  Where it is now, it looks like a biological scientist wrote it or even a chemical scientist, without consulting their atmospheric science buddy.  Integration will be key in strengthening the information already given.
The data provided is correctly cited and referenced, but it is very limited.  This area would benefit from graphs of diagrams that show the change of certain quantifiable characteristics over time.  The article assumes that we already know the purpose of the information provided, but without my current climate change class, I would not have concluded that coral is a proxy for studying climate change.  The definition of proxy needs to be stated “preserved physical characteristics of the environment that can stand in for direct measurements.”  When talking about proxies, it is important to note the level of certainty.  Although scientists are working to improve their precision, it is unlikely that proxies will ever be as precise.  This is important to note, to ensure that you are summarizing all sides of an argument.  Another topic that would be relevant would be the ocean’s important responsibility of being the sink of human-released carbon.  This is essential to understand why coral is changing and has changed in the past.
All of the sources listed are legitimate sources, with relevant and current (mostly) research which I applaud this article for.  However, I was able to find three more sources that were not listed that could be very beneficial for Wikipedia users.  I specifically like the last source due to its focus on one area through a case study.  This gives us a very tangible example of the relationship between coral and climate over time.  It even gives us some graphs, specifically figures 3 and 4, that could be helpful for visual learners such as myself.

thread_title: Proxy Critique

message: The article does not specifically state a proxy that it uses, however a potential proxy is the way scientists use the rings which form the coral. The article discusses each layer of rings that are formed every year that helps create the coral and helps to show ocean acidification in the environment. Just like we discussed how scientists used tree rings to find their age or ice cores to determine what was in the atmosphere during that time period. The coral layers are used to determine the acidification in the ocean. While I think the proxy they use is reliable and easy to comprehend, I do believe they could go a bit more in depth about the subject, or what other things they can determine from focusing on the coral layers. The article also discusses the Coral’s niche, or where it lives, and how the warmer temperatures have been affecting the populations in that specific niche. The increase in temperature has been favorable to slower-growing corals while other corals are being bleached and dying. 
The peer-reviewed articles seem to contain accurate and current information. A few other sources I found, which can help contribute to the article are Jokiel, Paul L., Christopher P. Jury, and Ilsa B. Kuffner. "Coral Calcification and Ocean Acidification." Coral Reefs of the World Coral Reefs at the Crossroads (2016): 7-45. Web. and Wooldridge, Scott A. "Differential thermal bleaching susceptibilities amongst coral taxa: re-posing the role of the host." Coral Reefs 33.1 (2013): 15-27. Web.
I think a visual to help show the different layers of coral would be interesting and help the reader get a better understanding by what the author means by the layers. This article is a bit easier to understand than other scientific article I’ve seen on Wikipedia however there are still a few things people who are not familiar with the topic may find confusing. Perhaps the article could delve a bit deeper and explain what a zooxanthellae is, I have no idea what that is!

thread_title: Article Critique

message: This article does well at explaining the proxy method.  It talks about how taking data from the coral communities can help reconstruct the levels during the Holocene. It also talks about how the increased temperature in the sea has caused coral reefs to be bleached and die.  The strength of this proxy method is that it shows how global climate change and the increase in temperatures are impacting the coral reefs. 
There isn’t much in this article, but it is an interesting topic, so potentially, making a new separate article just dedicated to coral climate research.Introducing what climate proxies are in this article could be helpful for better understanding the importance of coral reefs with climate proxy research, adding a link to a climate proxy could be helpful too.

thread_title:  Proposed merge with [[Polyp]] 

message: Hi, I came to this article because I am currently working on effects of climate change on oceans, the section on coral reefs. For this, I thought I would take an excerpt from one of the coral articles but I am now unsure where the bulk of the climate change content should be located: at coral, coral reef or coral bleaching, or a bit in each (or only at effects of climate change on oceans)? The IPCC report from 2021 has great information which can be fed into one or several of those articles:Cooley, S., D. Schoeman, L. Bopp, P. Boyd, S. Donner, D.Y. Ghebrehiwet, S.-I. Ito, W. Kiessling, P. Martinetto, E. Ojea, M.-F. Racault, B. Rost, and M. Skern-Mauritzen, 2022: Chapter 3: Oceans and Coastal Ecosystems and Their Services.

Cambridge University Press, Cambridge, UK and New York, NY, USA, pp. 379–550, doi:10.1017/9781009325844.005..
