Algae Met a Bear: Algae where you'd least expect them!
|Polar bear! In the EVERGLADES?!?!|
"Algy met a bear.
The bear met Algy.
The bear was bulgy.
The bulge was Algy."
I think my dad sang "Algy" to me when I was a little tyke, though in my 3-year-old wisdom I must have taken "Algy" as "Algae" and from then on aspired to become a phycologist. Now, some attribute this verse to Ogden Nash, while others chalk it up to Anonymous (that great and varied writer!). And while this verse may be humorous, it's not truly nonsense (though this sentence is). I've seen analysis of Algy and the bear as an allegory for existentialist being (what does it mean "to be"?), while others just say (spoiler alert) that the bear ate Algy. BUT, I think they're all wrong as a result of a translational error where "Algy" should be "Algae" as my 3-year-old self clearly realized. THEREFORE:
|Looks a little green 'round the edges.|
The bear met algae."
These lines are clearly discussing the cyanobacteria that grow in polar bear hair fibers! That's right - there's a type of cyanobacteria (blue-green algae) that lives in the hollow hairs of polar bears. This isn't a natural phenomenon, as the cold habitat of polar bears prevents algae from normally colonizing polar bear fur, but in warmer zoos algae find the hair follicles of the bears a cozy place to set up shop (and turn the polar bears what some think is a sickly "green around the edges").
"The bear was bulgy.
The bulge was algae."
|All pictures are a different scale: 1. Polar bear hair (tiny dots are the algae), 2. Close-up of the tiny Aphanocapsa dots, 3. Super close-up of Aphanocapsa montana, aka "the bulge". From Lewin et al. 1981.|
Glad we cleared that up.
But from here we can go completely crazy. You know that greenish tinge of sloths? Algae. (This one's really quite cool, too. Sloth hairs have cracks that allow rain to saturate the follicle, which in turn allows algae to grow hydroponically - in this case a green alga named Trichophilus welckeri is most common.
recent study by Pauli et al. 2014 and article that summarizes a very "crappy" pathway among sloths, moths, and algae - check it out and impress your friends! Make that one sloth-obsessive think twice about that love for adorable sloths. And even a new genus and species of red has been described from sloth hair!)
|Cute obligatory sea otter.|
I think I also promised a picture of a sea otter. You know what? Algae in their hair, too.
And if we look beyond hair, we see all sorts of epizoic algae (algae growing on animals): on shells, turtles, lizards, manatees! Moral of the story? Wash your hair. Algae are here to take over the world.
Oh? You don't see the relevance of this to graduate research in the Everglades? Well, I could attribute this to the strain of my M.S. research finally getting to me, propelling me into babbling analysis of children rhymes and my research project (I wonder if I could squeeze this into a chapter of interdisciplinary applications of the research...). But, really, I was thinking up ways of introducing those that need no introduction: ALGAE! Pop quiz for name recognition:
Agar, biofuels, harmful algal blooms, ice cream, Naked Juice, nori, oxygen, Spirulina.
|This author's personal favorite. And,|
yes, it does have carrageenan.
And apparently half the fat. Tasty algae.
A teaser: I mentioned algae on manatees. Dr. Tom Frankovich from FIU has actually looked into diatoms that live on manatees 'round these parts - super cool stuff. You may have noticed manatees that look a bit mossy. Let's amend that to "algae-y" and start singing, "Algae met a manatee. The manatee met algae." And they lived happily ever after.
