Talk:Tammar wallaby

Genome
I am moving some text about the genome here. I don't think that it should be included in the general article about the tammar wallaby.

The tammar wallaby's genome consists of 3.6 gigabases and has a short genetic map length of 1172 centimorgans.



This picture in the "Genome" section seems to show a wallaby eating something on the side of a tree. It does not illustrate the point made in the caption "Tammars are easy to keep in captivity." Axl ¤  [Talk]  09:16, 25 May 2012 (UTC)


 * I replaced it with the Budapest Buffalo zoo image. LittleJerry (talk) 03:58, 26 May 2012 (UTC)

Species
From "Taxonomy and classification", subsection "Subspecies": "All the island tammars were once thought to be of one species." Aren't they still thought to be one species? Axl ¤  [Talk]  23:14, 2 June 2012 (UTC)

The tammar wallaby is also native to new Zealand? The map in the infobox only shows Australia. Axl ¤  [Talk]  23:17, 2 June 2012 (UTC)


 * The island tammars are not considered one species. With regards to the map, I can't find one with New Zealand, I think the natural range is more imporant but one is free to create a map with both the natural and introduced ranges. LittleJerry (talk) 01:08, 3 June 2012 (UTC)
 * Ah, sorry, I misunderstood the meaning of the sentence about the island tammars. How about changing it to "The island tammars were once thought to be a separate species from the mainland population." Axl  ¤  [Talk]  08:16, 3 June 2012 (UTC)

Phylogeny
I have drawn a diagram of the of the phylogeny of marsupials based on the figure in Renfree MB, Papenfuss AT, Deakin JE, et al. This might be useful. File:Phylogeny of marsupials.png Graham Colm (talk) 17:53, 7 June 2012 (UTC)


 * Thanks, however I have one question. The source they cite for this tree actually gives three trees for Macropus phylogeny. Is is a problem? LittleJerry (talk) 18:33, 7 June 2012 (UTC)
 * Also, I would prefer a tree focused only on the Macropus genus. LittleJerry (talk) 18:36, 7 June 2012 (UTC)


 * The authors argue that the third tree is the closer approximation. Here is an edited version of my drawing, which shows the Macropodidae branch only. File:Phylogeny of Macropodidae.png Graham Colm (talk) 20:44, 7 June 2012 (UTC)
 * In the middle of the diagram, it is a little confusing as to which line corresponds to each species. Perhaps if you can bring the text slightly lower down and closer to the lines, that would be helpful. Axl  ¤  [Talk]  22:03, 7 June 2012 (UTC)
 * I have tweaked it; you might have to flush your cache to see the difference. Graham Colm (talk) 22:21, 7 June 2012 (UTC)
 * Okay, it's a little better. Isn't it possible to bring the text right on top of the lines? Axl  ¤  [Talk]  22:51, 7 June 2012 (UTC)

Papers
. Could you help me out with these articles?


 * Male germline development in the tammar wallaby, Macropus eugenii
 * Uterine morphology during diapause and early pregnancy in the tammar wallaby (Macropus eugenii)
 * Human chorionic gonadotrophin does not induce ovulation in the tammar wallaby
 * The tammar wallaby: a non-traditional animal model to study growth axis maturation LittleJerry (talk) 13:30, 4 April 2021 (UTC)


 * The first paper shows that spermatogenesis in wallabies is similar to that of eutherian (placental) mammals. However I don't think that this is particularly helpful in the article about "Tammar wallaby". Perhaps it might be worth mentioning in the article "Spermatogenesis". Axl ¤ [Talk] 16:25, 4 April 2021 (UTC)


 * The "Uterine morphology" paper doesn't really add anything new to the article. The article already mentions that Tammar wallabies use diapause, and I think that this is adequate. However the paper could be used to update this ancient 1973 reference. Incidentally, I see that the 2019 paper states the genus name Notamacropus. Is this a recent change to the genus classification? Axl ¤ [Talk] 16:44, 4 April 2021 (UTC)


 * The human chorionic gonadotrophin paper isn't helpful for this article. (I note that is also states the genus Notamacropus.) Axl ¤ [Talk] 16:50, 4 April 2021 (UTC)


 * Notamacropus is the subgenus, which is mentioned in the article. I have found other recent papers that use Macropus so I'm assuming its still the genus name and the other authors are using the subgenus to be more specific. LittleJerry (talk) 16:54, 4 April 2021 (UTC)
 * Hmm. "Notamacropus eugenii" is not "more specific" than "Macropus eugenii". Both names refer to the species. This paper states "The tammar wallaby (Notamacropus eugenii) (see [3,4] regarding the change of genus from Macropus) is one of the most intensively studied marsupials." The references are Jackson SM, Groves CP (2015) Taxonomy of Australian mammals, Melbourne: CSIRO Publishing, and Eldridge MDB (2010) Population and conservation genetics of marsupials. In: Deakin JE, Waters PD, Graves JAM, editors. Marsupial genetics and genomics. Dordrecht: Springer. pp. 461–497. Axl ¤ [Talk] 17:07, 4 April 2021 (UTC)


 * The paper on growth axis maturation doesn't add anything extra to the article. (It's relevant if you run a wallaby farm or if you're a scientist investigating growth mechanisms in infant animals.) Axl ¤ [Talk] 16:57, 4 April 2021 (UTC)

Fixed. Would you be able to do a quick copyedit. I'm finished with the updates. LittleJerry (talk) 17:08, 4 April 2021 (UTC)

The Australian Faunal Directory and various conservation agencies use Notamacropus bie.ala.org.au as the accepted name for this species. Other species have been recognised as this genus. ~ cygnis insignis 17:45, 4 April 2021 (UTC)
 * I added that information. LittleJerry (talk) 18:05, 4 April 2021 (UTC)

Possibly superfluous sentence
In the lede I read:

"It is one of many organisms to have had its genome sequenced. "

If complete genome sequencing is very common (as implied here) then it might be better to leave the fact (and the sentence) out as not notable enough. If, on the other hand, complete genome sequencing is not very common, it might be better to remove the implication that it is common with something like:

"Its full genome was sequenced in 2011."

 * I have changed the text per your recommendation. Axl</b> ¤ <small style="color:#808000">[Talk] 12:15, 9 April 2021 (UTC)

Disagreement over abbreviated genus
I believe the abbreviated genus in the taxonomy section should "N.", given the wallaby's newly assigned genus. The citation in question was when it was still considered to be under "Macropus"; since it is not a direct quote, there is no need to be a stickler for what the article says. Heh0002 (talk) 23:40, 30 November 2022 (UTC)


 * Then change the way the sentence reads. The article is currently saying something that the cited source didn't say. - UtherSRG (talk) 00:15, 1 December 2022 (UTC)
 * But it is. They're talking about the same species. The only thing that changed is the genus, which itself is abbreviated, so the only noticeable change would be a single letter. This is not as big of a deal as you think it is; for example, at Brown hyena, most of the sources are old and still refer to the species as "Hyaena brunnea", which is outdated and incorrect, yet they are still used to cite information in the article. Heh0002 (talk) 00:20, 1 December 2022 (UTC)
 * You know I understand the difference, so please listen when I say it's the wording that is at issue. - UtherSRG (talk) 00:23, 1 December 2022 (UTC)
