"Anaerobic respiration" article critique
[edit]Looking through the references, all sources seem to be credible as they belong to research articles, textbooks, or reliable websites. At first I was slightly confused as to why only fermentation was described in detail when there are many other types of anaerobic respiration; though after viewing the talk page I realize there is a big discussion on whether fermentation and anaerobic respiration should be merged, therefore clarity should be given as part of the article. The article is neutral. There are no claims or opinionated statements; everything is neutral and factual. Also, all information in this article is relevant to the article topic. The reduction potentials of manganese, cobalt, and uranium reduction is missing from the table under "Examples of respiration." Checking through half the citations confirms that there is no close paraphrasing nor is there any plagiarism involved. All citation links also lead to the correct source but some articles or textbooks are not free and require purchasing the source or providing permission to view the source. Specifically citation number six. Viewpoints in this article are well balanced and covers the necessary topics.

"Wetland methane emissions" article assigned
[edit]This article has not been rated on its importance or quality scale but I am immediately made aware of many errors. This article should be of high notability as the influx of greenhouse gasses into the atmosphere is a big problem with methane being a very potent greenhouse gas (Will be cited when editing article!). In regards to quality, I would rate this article as a start class because there is content to be added and much room for improvement. First of all the first section contains no citations or references where they are required; and there are MANY sections that require citations to a credible source. For example, "As one of the most significant natural sources of atmospheric methane, wetlands remain a major area of concern with respect to climate change" does not have a citation to any source; it seems as though there is a bias and is not factual. Furthermore, in the same paragraph the sentence "wetlands are one of the most significant natural sources of atmospheric methane" is repeated shortly after the first sentence which seems redundant, repetitive and just paraphrasing themselves. "Wetlands are the ideal anaerobic, or oxygen poor, environments for fermentation," rather than saying "or oxygen poor", this sentence could be made more concise by saying just "Wetlands are the ideal anaerobic environments for fermentation." and have the word anaerobic lead to the "Anaerobic" article. There are also a few spelling and punctuation errors that will require a simple proofreading of the article. For example, "hydrogenotrophicc" and unnecessary capitalization of "Peatland." To improve this article I will focus on providing citations where needed, proofread for spelling and grammatical errors, removing or revising biased and incorrect content, and adding information I deem important into the article. Although I will try to do minor edits to the entire article, I will focus on the first subtopic under the article title by adding citations and removing plagiarism.

Original- "Wetland methane emissions"
[edit]As one of the most significant natural sources of atmospheric methane, wetlands remain a major area of concern with respect to climate change. Wetlands are characterized by water-logged soils and distinctive communities of plant and animal species that have evolved and adapted to the constant presence of water. Due to this high level of water saturation as well as warm weather, wetlands are one of the most significant natural sources of atmospheric methane.
Most methanogenesis, or methane production, occurs in oxygen-poor environments. Because the microbes that live in warm, moist environments consume oxygen more rapidly than it can diffuse in from the atmosphere, wetlands are the ideal anaerobic, or oxygen poor, environments for fermentation.
Fermentation is a process used by certain kinds of microorganisms to break down essential nutrients. In a process called acetoclastic methanogenesis, microorganisms from the classification domain archaea produce methane by fermenting acetate and H2-CO2 into methane and carbon dioxide.
H3C-COOH → CH4 + CO2
Depending on the wetland and type of archaea, hydrogenotrophicc methanogenesis, another process that yields methane, can also occur. This process occurs as a result of archaea oxidizing hydrogen with carbon dioxide to yield methane and water.
4H2 + CO2 → CH4 + 2H2O

[edit]Contributing from 115-237 Tg of methane to atmospheric methane annually alone, wetlands are the biggest contributing factor of atmospheric methane in the world, wetlands remain a major area of concern with respect to climate change.[1][2] Wetlands are characterized by water-logged soils and distinctive communities of plant and animal species that have evolved and adapted to the constant presence of water. This high level of water saturation as well as warm weather is the cause of the high levels of methane production.
Most methanogenesis, or methane production, occurs in oxygen-poor environments. Because the microbes that live in warm, moist environments consume oxygen more rapidly than it can diffuse in from the atmosphere, wetlands are the ideal anaerobic environments for fermentation as well as methanogen activity. However, levels of methanogenesis can fluctuate as it is dependent on the availability of oxygen, more anaerobic environments allow for higher efficiency of methanogenesis.[3]

However, levels of methanogenesis can fluctuate as it is dependent on the availability of oxygen, temperature of the soil, and the composition of the soil; a warmer, more anaerobic environment with rich soil would allow for more efficient methanogenesis.
