Corals farm bacteria? | Reef Receipts

[@bthefountain]

This study had a really strong design and was very well documented. Glad we got to talk about it!!😊

[@hunterallen7335]

Very cool! Would love to read the paper if possible! What is the name (or do you have a link?)

Great discussion. One correction. Than was mistaken about boundary layer. A single stalk of coral produces a boundary layer in any current. Boundary layer does not include the dead zone inside a dense colony. The reason a golf ball has dimples is that they produce s strong boundary layer. This reduces friction because there is less friction between the boundary layer and the relative air around the ball. Sharks skin works in the same way. Cheers, Chris

I didn’t know that. I was under the assumption that the entire area directly around the coral was the boundary layer - Inside sections and outside.

[@Cgraseck]

As a pilot I was taught that boundary layer is a thin layer around any object moving through a fluid. The surface structure produces the boundary layer. Rough or dimpled surfaces produce stronger boundary layers and reduce the drag on the object. There is less friction between the boundary layer and the fluid moving past it because this is fluid on fluid friction not solid on fluid friction. Than implied that boundary layer was the dead zone inside a dense colony., but boundary layers form when there is fluid moving past and there probably isn't much movement at all inside a dense branching structure. I just wanted to point out that boundary layers form on all structures that stick out into the current. Cheers, Chris

@@CgraseckI really wish they’d put some context around how big this boundary layer actually is.

whoa than you are going beyond comprending , the studio is amazing then to blow our minds with such in-depth topics is awesome...

[@calvinsm]

Mind-blowing, indeed! Very interesting study. Thanks for this conversation!

[@tookmyhandle2]

I absolutely love this format, but i *strongly* recommend that you invite the first authors of these papers to be a part of the conversation. They are often only grad students and featuring them could have a positive career impact. They are also the best qualified to explain the work. As a molecular biologist myself, i am struggling with the number of misinterpretations and incorrect explanations in this series of videos.

[@bthefountain]

That’s a great idea! If you know any grad students that would like to feature their work, send them our way!!! 💜💚🩷

Love this format Than, keep them coming. Some feedback. I prefer the longer deeper dive on this kind of subject. I’d prefer the 1 hour version to the 20 minute version on this kind of subject - maybe that’s just me but less editing for you/Becca perhaps? Also some of the cuts were a bit rough but that’s what you have to do when chopping a long interview. Leave the quotes up longer so we can read them without pausing or rewinding. Also the cut ins of the coral vids are great. Love the channel and love the new style videos! Do more! Thank you! ❤

Best one you've done so far. Keep it up

Facinating

[@deanfielding4411]

I wonder if that’s another reason corals grow in a tighter for when flow is higher to help hold onto the boundary layer.

[@rowgegaming5048]

its like the coral is the city and the water inside the boundary layer is the suburbs.

[@leahnichol6665]

It is almost like some of the coral’s digestion is in the boundary layer of what we would say is outside the coral. No wonder they do not like being moved!

[@deanfielding4411]

How do they manage to do that? Something doesn’t stack up for me. Up to 5cm seems way too much, I can’t understand how, with the huge amount of flow, even in a reef tank, I doubt that any kind of microbial life that far from a coral. Can you clarify how big exactly this boundary layer is?

[@bthefountain]

The boundary layer size is dependent on the shape of the coral. It’s all about the fluid dynamics. The coral’s skin and polyps provide friction to the water as it passes it and changes the direction of the water and slows it down in a very small pocket around the coral. The more stream lined a coral is, the smaller the boundary layer will be. In general, smooth corals will have a smaller boundary layer than rougher corals. If you think about being at the beach and the water comes on shore in a regular pattern, but then you stand in the waves, you will change the pattern. That’s what the corals are doing to the flow on a much smaller scale.

So interesting!

[@trevorhenry7339]

After watching this and listening to it what do you think now after your Cipro video than? Crazy to think what we could be removing at that micro level using a medication like that. PS How much for a 1 mil syringe of SPS coral boundary water lol

[@07szim]

What are the water parameter's at tidal gardens? Ph/KH/Mg/Ca Salinity? - Change in parameters are the biggest thing to kill a coral, if we buy from tidal gardens, it would be awesome to know what the current water parameters are so we can match it for best survival of the coral.

Opening bacteria is like opening up space and the universe to man/womankind. The vastness of anything is not measured by length but complexity.

Conclusion… we know nothing 🤦‍♂️ Reef on

[@bthefountain]

lol. It’s super awesome to know that the boundary area has such a unique microbial profile. And that it wouldn’t have been discovered without looking at such small samples. 🤯
