Please list articles that you're considering for your Wikipedia assignment below. Begin to critique these articles and find relevant sources.

NOTE: I am unable to un-bolden below characters due to complex template formatting. Nevertheless, content should satisfy assignment requirements. Please let me know if there are any concerns surrounding this though!

Option 1

Article title: Photoheterotroph

Article Evaluation

1. Is the article's content relevant to the topic? --> Yes, photoheterotrophy is defined, novel research introduced (e.g., mitochondrial light capture), and metabolic pathway described
2. Is it written neutrally? --> Yes, no biases observed. This article is an impartial description of photoheterotrophs
3. Does each claim have a citation/Are the citations reliable? --> Yes (x2), all claims are backed by reliable citations (e.g., primary, peer-reviewed literature from Trends in Microbiology, PLOS, Scientific Reports, and Proceedings of the National Academy of Sciences
4. Does the article tackle one of Wikipedia's equity gaps (coverage of historically underrepresented or misrepresented populations or subjects)? --> No equity gaps were addressed
5. Check out the article's Talk page to see what other Wikipedians are already contributing. Consider posting some of your ideas to the article's Talk page, too. --> No discussions on the Talk page yet

Diversity of Arctic pelagic Bacteria with an emphasis on photoheterotrophs: a review

Improvements

• Add an Ecology section describing to include: Niche-space inhabited (see Winogradsky column), interactions w/ other microorganisms across a wide breadth of aquatic and terrestrial environments (e.g., extremes such hot springs, meromictic lakes, etc.), impact on global-scale biogeochemical cycling, vulnerability to climate change.
• Highlight advancements made by members of under-/misrepresented communities

Option 2

Article title: Ecological stoichiometry

Article Evaluation

2. Yes, authors exclusively include relevant content: defining ecological stoichiometry [i.e., physiological/elemental flexibility/homeostasis of organisms given nutrient composition provided by the environment (e.g., deviation/conservation of the Redfield ratio), influence of stoichiometry across food webs, and invertebrate stoichiometry)]
3. Yes, this article is unbiased and impartial
4. Each claim does not have a corresponding citation (e.g., "Ecological stoichiometry has been applied to studies of nutrient recycling, resource competition, animal growth, and nutrient limitation patterns in whole ecosystems. The Redfield ratio of the world's oceans is one very famous application of stoichiometric principles to ecology..."), but sources are reliable (e.g., primary, peer-reviewed literature)
5. No equity gaps were addressed
6. Talk section has one question (i.e., the incorporation of Energy flow subject-matter) that has not been addressed by the author

Sources

Generalized Stoichiometry and Biogeochemistry for Astrobiological Applications

Improvements

• Add a Microbial Stoichiometry section describing physiological C:N:P flexibility in a variety of environments, consequences of N/P saturation on impacted microbiomes, and applications for astrobiology, etc.
• Add peer-reviewed sources to the leading section (e.g., applications of ecological stoichiometry)
• Highlight advancements made by members of under-/misrepresented communities

Option 3

Article title: Thermophile

Article Evaluation

1. Yes, all content is relevant to the topic. Specifically, the original author defines thermophilic qualities, habitats housing thermophiles, classification schemes, and a fitness-improving genetic exchange mechanism (i.e., specific archaean example)
2. Yes, this article is unbiased and impartial
3. Sources reliable (i.e., primary peer-reviewed from journals such as Extremophiles and Molecular Microbiology, in addition to Brock's Microbiology textbook). No major source-related issues were identified, though Wikipedia was leveraged heavily.
4. No equity gaps were addressed
5. The talk section includes questions about the physiological capabilities of thermophiles. For example: Do they generate heat independently? Plus, the below from user EncMstr (2012) per conflicting facts from Volcanoes of the Deep Sea

1. • "Is the temperature range correct?"
   • "How did they find these creatures inside volcanic tubes and fissures?"
   • "What kind of lifespan do thermophiles have?"
   • "How do they reproduce?"
   • "Do they depend on other creatures to metabolize sulfur (or whatever makes them go)?"
   • "Do they use the heat directly? (Or are they simply adapted to live in it?)"
   • "Are these really related to the Mickey Hot Springs creatures in 60 °C (140 °F)?"

Improvements

• Add an Ecology section to address questions like: How do thermophiles interact with each other (mutualistic/competitive relationships)? Do they contribute significantly to C/N/S cycling? Are their habitats threatened by human interference?
• Provide additional examples of unique thermophilic physiologies
• Highlight advancements made by members of under-/misrepresented communities. Additionally, discuss the role thermophiles may play in indigenous populations, if applicable.
