Bibliography

As you gather the sources for your Wikipedia contribution, think about the following:

Is the source from a reliable publication?
- Reliable publications include established newspapers, academic journals and books, textbooks, and other published sources with reputations for accuracy and fact-checking.
- Unreliable sources include blog posts and other self-published works, press releases, and social media posts.
Is the source verifiable?
- In order for a source to be considered verifiable, other editors should be able to consult the source.
Is the source independent of the subject?
- Is the source connected in any way to the subject? This is especially important when writing biographies or about organizations.
- For example, if you were writing a biography, sources like the person's webpage or personal blog would not be considered independent.
Is the source primary or secondary?
- Primary sources include first-hand accounts, autobiographies, and other original content.
- Wikipedia allows limited use of primary sources, but typically only for straightforward, descriptive statements of facts, and only if they are published and verifiable without requiring specialized knowledge.
- Secondary sources should be the main basis for a biography on Wikipedia.
If you're working on a topic related to medicine or psychology, ensure that your sources follow these special guidelines.
If you're creating a new article, consider the following:
- Ensure that your topic meets Wikipedia's notability guidelines.
- In order for a topic to meet the notability requirement, you must be able to identify 2-3 sources that are reliable, verifiable, and independent of the subject you're writing about.
- Finding sufficient sources to establish notability can be especially hard when writing about people or organizations.
- Sources that are not independent of the subject might be useful additions, but don't count towards the notability requirement.
- Wikipedia has developed special guidelines for writing about living persons. Please follow these carefully.
- Wikipedia has a series of guidelines for writing about different categories of people, such as academics and artists. If you're trying to create a new entry about a living person, please look at these carefully.

If you're not sure whether a source is reliable, ask a librarian! If you have questions about Wikipedia's sourcing rules, you can use the Get Help button below to contact your Wikipedia Expert.

Bibliography

Source One: Revision of the Eurycea quadridigitata (Holbrook 1842) Complex of Dwarf Salamanders (Caudata: Plethodonitae: Hemidactyliinae) with a Description of Two New Species^[1]

-Although the current Complex only has E. chamberlaini, the molecular studies in this article suggest there are at least five other genetic lineages. All five species are said to be morphologically distinct. Two new species from the complex are described to help elevate the subspecies to a species status. This study was done in 2017 so it is of the more recent, published work. This article also highlights how little we still know about E. chamberlaini and that we are still actively collecting data to further understand the species. The researchers found species divergence from E. quadridigitata estimated 27-15 Million years ago. In the description of E. chamberlaini the researchers do not list larval descriptions and instead tell readers to refer to the original larval descriptions that Harrison and Guttman did in 2003 when the species was initially researched. They do add that E. chamberlaini prefers lotic breeding areas when compared to lentic ones, often being found near streams and seepage from springs. E. chamberlaini populations were not found anywhere else other than NC and SC during the time of this research. E. chamberlaini does have relatively short larval periods, with some individuals reaching maturity after just two months.

Source Two: Reproductive Biology and Population Structure of Eurycea chamberlaini in North Carolina^[2]

-Detailed reproductive cycle, this study was done specifically for this purpose as there was previously no in-depth reproduction research published. In this study the researchers found females to on average to be larger than males, though it is to be noted that this may be due to smaller females hiding more frequently and also the sample size was small. The results suggest that the population structure of E. chamberlaini is similar to that of other coastal salamander population structures. The reproductive season is October through April. The samples collected in this study were also utilized in the third source I have used, which also researched reproductive tactics E. chamberlaini displays. Most individuals collected for the sample were found underneath leaf litter along the banks of a swamp above the floodplain in Craven County, NC. 392 individuals were collected over the course of the study, approximately 30 individuals a month. They captured 201 females and 191 males. Most specimens captured were of sexual maturity but there were 26 females immature and 27 males immature. Eggs were found to hatch 30-40 days after deposition with the larval period lasting from 3-6 months. The salamanders were found to reach sexual maturity within the same year they metamorphosed. Even with the information found, the researchers still believe further studies need to be done for dwarf salamander populations to make sound comparisons regarding metamorphosis phenology.

Source Three: Cranial Courtship Glands of Eurycea chamberlaini^[3]

-Continues with more in-depth reproductive research, utilizes the same samples taken from the Craven County sample Davenport et. al. collected. Specifies on mating strategies E. chamberlaini uses when seeking out females. Males are considered "searching morphs" which basically means they coerce females via pheromones to mate with them. The pheromones are secreted through mental glands. E. chamberlaini has lateral head courtship glands only during the putative mating season and these glands are only found in the males. Both the males and females have nasal glands though, which are suggested to also secrete pheromones. Although both sexes have nasal glands, the nasal glands found in male specimens were larger. These nasal glands have similar secretory cycles to the mental glands.

Source Three: Herps of NC Webpage^[4]

-Lists updated information regarding E. chamberlaini's status, species now listed as "State Species of concern". Previously this year it's status was being reviewed. Has basic level information regarding E. chamberlaini and it's diet, habitat and appearance.

Examples:

Luke, Learie. 2007. Identity and secession in the Caribbean: Tobago versus Trinidad, 1889–1980 Kingston, Jamaica: University of the West Indies Press.
- This is a book published by a university press, so it should be a reliable source. It also covers the topic in some depth, so it's helpful in establishing notability.
Galeano, Gloria; Bernal, Rodrigo (2013-11-08). "Sabinaria , a new genus of palms (Cryosophileae, Coryphoideae, Arecaceae) from the Colombia-Panama border". Phytotaxa.
- This is a peer-reviewed scientific journal, so it should be a reliable source. It covers the topic in some depth, so it's helpful in establishing notability.
Baker, William J.; Dransfield, John (2016). "Beyond Genera Palmarum: progress and prospects in palm systematics". Botanical Journal of the Linnean Society.
- This is a peer-reviewed scientific journal, so it should be a reliable source for a specific fact. Since it only dedicates a few sentences to the topic, it can't be used to establish notability.

Outline of proposed changes

Since the article is just a stub right now, I plan to add more information to it so it can grow some more. There are currently no sections so I want to separate the work already there into it's correct area. I plan to add the following sections: Description of Species (color, length and size, four toes, larval appearance) Habitat and ecology (where they prefer to live, a section to include that they are highly susceptible to climate change and habitat loss since they are endemic to NC and SC only) Diet (the stuff they eat) and Reproduction (all the reproductive characteristics they display that has been discovered so far). I also need to change the species status from "data deficient" to "State Species of Concern". I also will have an introduction area at the beginning where I will preface that research is scarce and the species is still being actively researched (their tiny size makes them hard to find and study) as well as including the rest of the original wiki page that the person before me did. I will be getting the habitat, diet and appearance information mainly from the NC Herps website and the original description done by Harrison and Guttman and then I will add the Harrison and Guttman publication to my references once I read it. The reproductive section will be from the information found in my other three articles.

Now that you have compiled a bibliography, it's time to plan out how you'll improve your assigned article.

In this section, write up a concise outline of how the sources you've identified will add relevant information to your chosen article. Be sure to discuss what content gap your additions tackle and how these additions will improve the article's quality.

Consider other changes you'll make to the article, including possible deletions of irrelevant, outdated, or incorrect information, restructuring of the article to improve its readability or any other change you plan on making. This is your chance to really think about how your proposed additions will improve your chosen article and to vet your sources even further.

Note: This is not a draft. This is an outline/plan where you can think about how the sources you've identified will fill in a content gap.
