Hi everyone,
I do not believe that there is anyone here on the list that expects us
to read every paper that is published in our field. I think that what
appears to be sadly lacking is the curiosity of chasing after the
original idea. I found Wiedenmann et al. (2023) article of great
interest, but clearly the hype in the mainstream media took it over the
hill with headlines like this:
https://scitechdaily.com/darwins-paradox-of-coral-reefs-solved-scientists-unravel-age-old-mystery/
Not that long ago we were told the same:
https://blog.education.nationalgeographic.org/2016/04/11/scientists-solve-darwins-paradox/
I am happy that we solved "Darwin's Paradox" not once, but twice!
With thousands of research papers from the past now digitized, and
easily available trough most university libraries, it really is not that
difficult to search if someone else has also done research on the topic.
In case of Wiedenmann et al. (2023), the digestion of zooxanthellae by
the coral animal. I used the 'Google Scholar' and searched for
"digestion of zooxanthellae" and this is the results that popped up:
https://scholar.google.com/scholar?hl=en&as_sdt=0%2C5&q=digestion+of+zooxanthellae&btnG=
Boschma's 1925 article is second from the top, yet it did not make it as
a reference in Wiedenmann et al. (2023). If a claim is being made of a
major discovery (well, the mainstream media certainly seems to think so)
than it is only fair to search the literature for past work on the
subject.
In 1996, Titlyanov et al. (2019) also concluded that: "... hermatypic
corals are capable of regulating their zooxanthellae populations by
digestion and extrusion of zooxanthellae remnants". Yet, this article is
also missing from Wiedenmann et al. (2023) reference list. For anyone
interested in that article here is a link:
https://www.int-res.com/articles/meps/139/m139p167.pdf).
I don't expect anyone to read all the papers being published on coral
reefs and corals (an impossible task to begin with), but I am
disappointed that more effort is not being made to search the vast
literature that is now at our fingertips for more relevant articles.
Cheers,
Tom

in the first sentence of the Wiedenmann et al. (2023) article would have
been nice.
