Talk:Western grey kangaroo

Untitled

why would someone put money into creating this animal? This animal is a hybrid right? —The preceding unsigned comment was added by 68.252.199.152 (talk • contribs) .

What money? This is not a hybrid. Where did you get your information to ask this question? - UtherSRG (talk) 13:44, 13 March 2006 (UTC)

Some information about its breeding patterns would be good. I understand the Western Grey is a seasonal, not opportunistic, breeder, unlike many other macropods. —The preceding unsigned comment was added by 130.95.128.51 (talk • contribs) .

My apologies to the unidentified user whose edit I just reverted, although there was no need to change the article in the first place--they were not "spelling mistakes", the words in question were spelled in European English. Also if somebody could fix the vandalism (which doesn't appear in the article edit mode) that would be great. 97.104.210.67 (talk) 20:22, 8 August 2009 (UTC)

Core Temperature and Thermoregulation

Danielle Chibuzo (talk) has added a new section "Core Temperature and Thermoregulation". There are a number of problems

• 1) - editor describes the species as being nocturnal. This species is not normally considered to be nocturnal and I can't find support in the supplied references
• 2) - a duplicated citation "webwizard, Journal manager, Table3_Fukuta et al (2017).pdf". dx.doi.org. Retrieved 2022-11-28." connects to a page with an error. The description in the citation is not sufficient to determine what the reference was supposed to be
• 3) - "that has a core body temperature that varies based on daily ambient temperatures" makes the species sound ectothermic. Better would be "that varies its core body temperature based on daily ambient temperatures".
• 4) - "This species is known to use a unique evaporative mechanism called saliva spreading to cool themselves down, but they appear to only use it during exercise, it was not frequently observed.14" a) the mechanism isn't remotely unique, many species use it. b) the reference relates to the red kangaroo which is not only not the same species, its not even the same genus.

Once adequate references are supplied there may be more issues.

Could the editor please address these issues, otherwise a remedy may have to be reversion of the addition. Jameel the Saluki (talk) 06:08, 28 November 2022 (UTC)

Agreed. I've made a few minor edits to the section for formatting, but that first citation needs a huge adjustment once we can find it. @Danielle Chibuzo: - UtherSRG (talk) 12:06, 28 November 2022 (UTC)

User:Danielle Chibuzo has not returned to address any issues or clarify the citations. After reviewing the available literature I am fairly convinced every sentence in the section has a fundamental error, and that none of the text can be retrieved or improved upon. Removing the section is only valid option from my point of view. Jameel the Saluki (talk) 08:35, 1 December 2022 (UTC)

I'm Danielle's instructor in the course she is taking and where she wrote this paragraph of text based on two primary journal articles. It's not clear to me why all of her added text was removed and I am restoring much of it. To address your comments:

1) Under "Diet" it says "It feeds at night". This is the very definition of a nocturnal animal, is it not?

2) I fixed the citation error.

3) This is not ectothermy, this is heterothermy. This is a physiological trait many animals that live in hot environments share. Wikipedia has a good page on this. I rephrased it to what you suggested, if you think that makes it clearer.

4) I'm not sure why she used this reference here, you are right it is a different species. I cut this. SparrowGrrl (talk) 22:59, 12 December 2022 (UTC)

Thankyou for taking the time to improve the addition, and for supplying the missing reference. Comments:

• Re Nocturnal. This presents a small conundrum. The western grey kangaroo is usually thought of as crepuscular, and the citation in the "Diet" section confirms it at that location. (the text in the section does say different but with no citation). However the author of both of the references for your section (same one) clearly thinks that the kangaroos in the studies are nocturnal, but doesn't really supply much evidence for this. In fact it is stated at one point "Because the kangaroos were free-living in a large reserve, they were observed only infrequently, and we do not know the cause of the rapid increases in Tc depicted in Fig. 6. These increases may have been due to exercise activity, although they all occurred during the normal rest phase". I'll have to let it stand at the moment and see what research there is on the subject for clarification.
• 2nd sentence now makes much more sense with the rewording and new citation. I'd like to change it to "The kangaroo's lowest daily core body temperature occurs mid-morning. In the summer, this was 2.2 °C (4.0 °F) lower than during the cooler spring days."
• 4th sentence " In another study conducted to explain why the western grey kangaroo’s core body temperature decreases as summer progresses, researchers found that as surrounding temperatures increased by 21°C during the day, wild kangaroos’ core body temperature decreased by ~1°C.". It was an earlier study (by 7 years) by the same people. The later study was the first report of the seasonal change in the temperature cycle. I also can't find anything in the citation to justify the claim on temperature made in the sentence. Finally even if both parts of the sentence were true I don't see the notability of the statement.
• 5th sentence "Researchers also discovered that changes in core temperature were tightly controlled during active hours at night." I can't see how this sentence is justified in any way. Firstly it is unclear what "tightly controlled" means. Surely the whole point of both papers it to demonstrated that the core body temperature is controlled at all times of the day (with the exception of spikes of hyperthermia). The variation over in core body temperature over night is comparable with that during the day. Or does this relate to specific hours at night, the active hours? But which are these? I can't find any wording in either paper that would justify the sentence.

Sorry for the delayed response; I made your suggested changes to the 2nd sentence and cut the 4th and 5th sentences, I agree I don't think the section really needs them (notability). SparrowGrrl (talk) 03:11, 4 July 2023 (UTC)
