Critique on Coral: It looks like this article is very good and complex. With its GA-Class rating, the article is fairly comprehensive in its coverage of corals (although the physiology is not as in-depth as it could be). It covers ecology, taxonomy, reproduction, anatomy, threats, human uses, and many other topics. Most of the commentary on this article appears to be from educated and civil editors, as they usually justify edits with updated information.

On Porites: This article, which covers the genus that I've researched so far, has very little information on the genus. There are small sections on Paleoclimatology and Aquarium Trade, and a list of species. However, it may be beneficial to add a bit on Physiology specific to the genus, or at least to certain species within the genus.

On Porites cylindrica: This article also could use some information on physiology, as it only has brief sections on Description and Distribution.

On Porites lutes: None exists. I could add a bit on the physiology of this species, citing research that I've done (though admittedly I doubt I could do it justice). BBres96 (talk) 15:45, 11 March 2016 (UTC)

Hi Ben, it looks like your working with some fairly robust articles, that's good. The one problem I see is that if you created the P. Lutes page, you couldn't just add physiology because then the article would be too narrow. I'm not sure how you would resolve that, but it's something to think about.

Hi Ben, thanks for looking at these articles, and for commenting on Jacob's evaluation of the Daphnia article. I await your decision of what article you would like to work on this semester. Rico.schultz (talk) 18:22, 18 March 2016 (UTC)

@BBres96: Dear Ben, thanks for commenting on Jacob's Daphnia contribution. I think that the solution to Jacob's comment about zooxanthellae is to link the term in your text to the wikipedia page on that topic.

Ben, you need more references and you need to post here the draft text of your contribution to the wiki page. At this point your taxon team members have nothing to peer review.Rico.schultz (talk) 16:35, 26 April 2016 (UTC)

For the article: Porites

Ecology

Corals in the genus Porites are found in reefs throughout the world. For example, it is a dominant taxon on the Pandora platform of the Great Barrier Reef. In a 1985 survey, Potts et al. identified 7 dominant species: P. lobata, P. solida, P. lutea, P. australiensis, P. mayeri, P. murrayensis, and P. anae. The oldest of six colonies in this reef was approximately 700 years old, and was estimated to be growing at 10.3 mm per year.

Meyer and Schultz (1985) demonstrated that P. furcata have a mutualistic relationship with the schools of french and white grunts (Haemulon flaviolineatum and H. plumieri) that rest in their heads during the day. The fish defecate on the coral, providing it with ammonium, nitrogen, and phosphorus compounds. Coral heads with nesting grunts experience significantly higher growth rates and Nitrogen composition than those without (Meyer and Schultz 1985).

Physiology

Some species in this taxon demonstrate high levels of halotolerance. In the Gulf of Thailand, for example, P. lutea acclimates to daily tidal shifts of 10-30% salinity. Moberg et al. (1997) determined that when the salinity declines, the symbiotic zooxanthellae decrease their photosynthesis rate as the coral contracts its polyps to protect them. The corals maintain their metabolic rate by temporarily switching to heterotrophy, consuming prey such as brine shrimp and other zooplankton (Moberg et al. 1997).

Porites growth rates can be determined by examining annual rings in their skeleton. This method was used to determine that P. astreoides grows its skeleton by approximately 3.67mm/year, calcifies at approximately 0.55g/cm²/year, and increases density at approximately 1.69g/cm³/year (Elizalde-Rendon et al. 2010). Additionally, coral such as P. furcata demonstrate seasonal growth variation. Meyer and Schultz (1985) observed that peak growth occurs between May and August.

Threats

Threats to corals in the genus Porites include predation, climate change, and anthropogenic pollution. When exposed to increased temperatures and copper, P. cylindrica slowed its rate of production. Additionally, the zooxanthellae reduced their photosynthesis rate when exposed to both stressors (Nystrom et al. 2001).

Done and Potts (1992) observed that larvae in Porites are vulnerable to competition from other corals and predation from sea urchins. Additionally, mortality likelihood increases following strong storms (Done and Potts 1992).

Hi Ben, It looks like you have a pretty good start on your article contribution. I think its interesting how you are addressing so many different topics, e.g. threats to coral, their ecology, from a physiological perspective. However, because of this there is some confusion about the general language involved with coral that your are using here, such as "zooxanthellae," as I would not know terms like these unless they were explained. This being said, these are probably discussed in other parts of the article, so this confusion is probably just a consequence of not reading it within the context of the whole article. As for improvements, it may be useful to provide more general information about physiology in order to provide context for what you're saying. I also think it may be better to avoid referring directly to a study, and instead simply talking about the results of the study, but this may be more of a matter of personal taste. You also need to make sure that species' names are in italics, but I had the same problem because formatting like that does not copy over. JacobMwiki (talk) 07:30, 27 April 2016 (UTC)

Meyer and Schultz (1985) demonstrated that P. furcata have a mutualistic relationship with the schools of French and White Grunts (Haemulon flaviolineatum and H. plumieri) that rest in their heads during the day. The fish provide it with ammonium, nitrates, and phosphorus compounds. Coral heads with resting grunts experience significantly higher growth rates and nitrogen composition than those without.

Physiology

Some species in this genus demonstrate high levels of halotolerance. In the Gulf of Thailand, for example, P. lutea tolerates daily tidal shifts of 10-30% salinity. Moberg et al. (1997) determined that when the salinity declines, the symbiotic zooxanthellae decrease their photosynthesis rate as the coral contracts its polyps to protect them. The corals maintain their metabolic rate by temporarily switching to heterotrophy, consuming prey such as brine shrimp and other zooplankton.

Porites growth rates can be determined by examining annual rings in their skeleton. This method was used to determine that P. astreoides grows its skeleton about the central axis by approximately 3.67mm/year, calcifies at approximately 0.55g/cm²/year, and increases density in this region of the body at approximately 1.69g/cm³/year. Additionally, Meyer and Schultz (1985) reported that coral growth varies seasonally. They observed that P. furcata's growth rate peaked between May and August, which is summertime in their Caribbean habitat.

Threats

Threats to corals in the genus Porites include predation, climate change, and anthropogenic pollution. When exposed to increased temperatures and copper, P. cylindrica slowed its rate of production. Additionally, the symbiotic zooxanthellae reduced their photosynthesis rate when exposed to both stressors.

Done and Potts (1992) observed that when settled, larvae in Porites are vulnerable to competition from other corals and predation from sea urchins. Additionally, mortality likelihood increases following strong storms.

@BBres96: Ben, I see that you published your sections on Porites ecology physiology after adding a notification to the talk page. Well done! A couple small things should be corrected. The salinity shifts in the physiology section are represented in % terms; are you sure that isn't parts per thousand? There is a symbol for this, see the wikipedia article on parts-per notation. You might reduce the space between paragraphs in the physiology section. Finally, you might link the 'Additionally, ' sentence in the last paragraph of the physiology section to the Meyer and Schultz reference. Rico.schultz (talk) 13:26, 3 May 2016 (UTC)
