Looks pretty good, just a couple points I've noticed so far:

  • Fixed.
  • Still has some overcitation. Particularly at
    • "The oscillation of a target's wings also produces amplitude shifts, which gives a CF-bat additional help in distinguishing a flying target from a stationary one."
    • "This means that the bat can get an almost continuous stream of information – essential when objects are close, because they will pass by quickly – without confusing which echo corresponds to which call."
    • "The second proposes that laryngeal echolocation had a single origin in Chiroptera, i.e. that it was basal to the group, and was subsequently lost in the family Pteropodidae."
    • "The adaptation of echolocation calls to ecological factors is constrained by the phylogenetic relationship of the bats, leading to a process known as descent with modification, and resulting in the diversity of the Chiroptera today."
    • "The result is that range is encoded by location on the cortex, and increases systematically across the FM-FM area."
    • "Tectonic openings created the Southern ocean with a free flowing Antarctic Circumpolar current."
  • Slimmed.

I'll come back in a bit to continue looking over the article. -- Primium (talk) 16:46, 9 October 2023 (UTC)[reply]

Continuing review:
  • Missed overcitation in "The adaptation of echolocation calls to ecological factors is constrained by the phylogenetic relationship of the bats, leading to a process known as descent with modification, and resulting in the diversity of the Chiroptera today."
  • Fixed.
  • "See" is perhaps the wrong word in "With echolocation, the bat or other animal can see not only where it is going but also how big another animal is, what kind of animal it is, and other features."
  • Tweaked.
  • The wording in "The calls of bats have been most intensively researched, but the principles apply to all echolocation calls" suggests all echolocating animals, but I don't see where this is supported in the first two sources (and can't find access to the third source). It's possible I've missed it, though.
  • Added source.
  • Might be good to define the term "aerial-hawking" (the article on hawking is exclusively about birds).
  • Added.
  • The name "whispering bats" isn't used in its source. Should find another source as evidence they are really called this.
  • Added. It's a widespread usage.
  • "A single echolocation call [...] can last anywhere from 0.2 to 100 milliseconds in duration" - These specific durations are not mentioned in the provided source.
  • Added desc and ref.
  • Removed.
Again, I'll come back later to continue. I've reviewed about a third of the article, so far. -- Primium (talk) 18:58, 10 October 2023 (UTC)[reply]

Primium?

Taxonomic range

[edit]

Bats

[edit]
  • Are you sure basicbiology.net is a reliable source? (ref 38)
    • It seems perfectly adequate for its purpose, plain and factual.
  • 'In recent years researchers in several countries have developed "bat call libraries" that contain recordings of local bat species that have been identified known as "reference calls" to assist with identification.'
    • Should have a comma after 'in recent years'.
      • Added.
    • The phrasing in the second half of the sentence feels a little awkward. Maybe something more like 'In recent years, researchers in several countries have developed "bat call libraries" that contain recordings of local bat species known as "reference calls" to assist with identification.'
      • Simplified.
  • 'some insects (moths in particular)' - This is the first instance where 'moths' is wikilinked, but it's not the first instance of 'moths' in the article. The first instance is in 'Acoustic features'.
    • Fixed.
  • If possible, it would be really great if we could get a diagram of a bat's ear for 'Inner ear and primary sensory neurons'.
    • Noted.
  • 'This area of high sensitivity to a specific, narrow range of frequency is known as an "acoustic fovea"' - 'fovea' links to Fovea centralis, which is about the eye. I don't see an article on acoustic fovea, but there is Doppler shift compensation.
    • Linked.
  • 'Neurons in this region respond to CF signals that have been Doppler shifted' - Could link to Doppler shift.
    • Already linked above.

Toothed whales

[edit]
  • 'absorption' links to underwater. Is this intended? Seems like it was meant to be something more technical.
    • Removed.
Whale evolution
[edit]
  • This whole section is overly technical. I think it would be difficult for an average reader to parse. Almost everything I'm suggesting a link for would benefit from a brief explanation, definition, or general simplification.
    • Copy-edited and added diagram for simplicity; added links and definitions.
      • Really great work.
  • 'at the onset of the Oligocene' - As with the middle and late Eocene, you should define the period of this epoch.
    • Done.
  • 'it has been found that extant odontocetes are monophyletic' - Please define and link 'monophyletic'.
    • Done.
  • 'an oligocene stem odontocete, and once in the crown odontocetes.'
    • 'oligocene' needs a capital O.
      • Fixed.
    • 'stem' and 'crown' might benefit from explanation.
      • Linked.
  • 'Neogene' - should be linked to Neogene and the period defined.
    • Done both.
  • 'Tmc1 and Pjvk are proteins' - TMC1 should be wikilinked here. The next sentence should have the link removed.
    • Done.
  • CLDN14 can be linked.
    • It is linked.
  • 'Cranial telescoping' - Is this what it sounds like? They can telescope their cranium? Sounds cool, but definitely needs further explanation.
    • Added.
Mechanism
[edit]
  • 'However, because three of the groups developed NBHF prior to the emergence of the orca, predation by other, ancient, raptorial odontocetes must have been the driving force for the development of NBHF, not predation by the orca. Orcas, and, presumably, ancient, raptorial odontocetes such as Acrophyseter, are unable to hear frequencies above 100 kHz.' => (Removed excess commas) 'However, because three of the groups developed NBHF prior to the emergence of the orca, predation by other ancient raptorial odontocetes must have been the driving force for the development of NBHF, not predation by the orca. Orcas, and presumably ancient raptorial odontocetes such as Acrophyseter, are unable to hear frequencies above 100 kHz.'
    • Done. Appositional commas are not however an error.
  • 'For all sonar systems the limiting factor' - Needs comma after 'systems'.
    • Fixed.
  • 'fatty organ known as the melon.' - Melon (cetacean) is linked here. It should be removed, as it will be added to previous use.
    • Fixed.

References

[edit]

Appear to be in good order. Links are accessible.

  • "A proposed echolocation receptor for the bottlenose dolphin (Tursiops truncatus): modeling the receive directivity from tooth and lower jaw geometry" - Probably doesn't need the link to bottlenose dolphin in the title.
    • Unlinked.

I asked above if you're sure basicbiology.net is a reliable source (ref 38). I'll trust your judgement. This is the only remaining item.

  • Yes, but I've replaced it now.

Conclusion

[edit]

Great work! It looks excellent (especially the whales section - so much easier to read). I'll update the talk page and mark it GA. -- Primium (talk) 19:30, 17 October 2023 (UTC)[reply]
