slime molds are my hobby?... my pets??? * 2
    #8535097 - 06/17/08 08:17 PM (15 years, 9 months ago)

So I found these immature sporangia of a Stemonitis species on a very spongy log yesterday. At this point in their development they look like little translucent sessile globes goo... or slime. After removing slivers of the bark with my pocketknife they were placed in the collection bag.


The samples were then placed in a humidity box - any small container will work. As you can see, these were placed in a small plastic container with a moist paper towel in the bottom with another loosely draped over the top.


A few hours later they started to mature. You can see how the orb-like structures are being lifted up off the substrate and becoming distinctively stipitate.


I had to go to bed because it was really late -- they looked like this the following morning. More intermediate photos would have been cool.


Finally, this is what they look like tonight, around 25 or 26 hours after collection.



Here are a few more slimes that weren't as strikingly transformative.

Nice! Slime molds are awesome, try to see if you can watch any of the spores enter the amoeba like stage!!!

Its blows my mind that slime molds are actually protists; and that  Kingdom protista contains plantlike (algae) animal like (protozoans) and fungi like (slime molds) organisms.

The kingdom Protista is defunct.

Thanks everyone. Thought y'all might like.

Dishez: I'll try however it would be doubtful I could capture images. I do intend to do some microscopy -- which i can photograph. Primarily spores and hopefully capillitia.

Tripsis: Protista is defunct? So it is officially Amoebozoa now (for now)?

Snoot: i'm just using a stock point and shoot canon A630, taking a ton of shots, and cropping the hell out of which ever looks best.

Protista is a polyphyletic kingdom, meaning it can't be correct. Slime moulds are Amoebozoans, yes, but that only refers to their phylum. The "Kingdom Protista" still stands but only for convenience. It is accepted though that it really has no meaning as such.

Ok I see what you are saying.... Essentially all systems of classification are for convenience more-or-less.

Particularly within the realm of biology, a system can't be expected to represent the tremendously broad diversity of biological lifeforms without becoming hopelessly unwieldy.

Excellent work, George.  :thumbup:

Any chance on getting some time lapse on those puppies?

Here's a time lapse someone made with your model:

Hmmm no not exactly. The level of species is the only classification with any true biological meaning, the rest being for convenience and are subjective, but each taxon should be part of a monophyletic clade. Algae for example are polyphyletic, so the term has no real meaning because it could apply to a number of different organisms, each completely unrelated. The other "kingdoms" (the whole idea of kingdoms is rather outdated) are more-or-less monophyletic, but the protists are a bunch of disparate organisms that didn't fit into the other so were all lumped together.

That is cool, it looks like all you need to do time lapse video with any camera that has a remote shutter jack is a device that connects two wires at a specified interval.

Here are some people that use a ti-83:

Yep.

Here is cool time lapse of slime molds and other mushrooms.  I'll bet George could do a better one.

I would love to do that. I have a program called iStopMotion that would be great for creating high-resolution time lapse stuff... However I would need to figure out a way to make the camera automatically take the photos. i don't believe the A630 is equipped with remote shutter release.

I'm aware of this, but since most classifications are pretty arbitrary, so what?

Anyways, has there been some official deeming of the protista defunct?


I know people are always proposing new classifications based on current non-stupid models, but is there any group that's adopted such?

How does tha twork in biology?

In chemistry we have one group pretty much: IUPAC.  Doesn't biology have a bunch of groups that fight like schoolkids?
