Slime molds (Myxomycetes) are beautiful, weird, and amazing organisms. Often mistaken for fungi, they are actually single celled, yet they grow and efficiently move in search of food, can start and stop their life cycle based on environmental conditions, and even change colors several times during their brief life cycle. They can be beautifully colored, frequently iridescent, and can be ornately shaped. And better still, they can be found in much of the world - maybe even in your yard.

My guest today, Alison Pollack, is a renowned slime mold photographer and unabashed enthusiast of slime molds and their habitats. If you follow nature photographers on Instagram, perhaps you count yourself as one of her nearly 60,000 followers.

Today, Alison tells us what exactly a slime mold is - and no, it is not a mold or fungi. She tells us about their fascinating lifecycle, where they grow, and how to find them.

Alison then tells us about her astonishing macro photography of slime molds - both in the field and in her home studio. She walks through her process, technique, and equipment she uses to create her acclaimed photos. If you do nothing else, follow her on Instagram @marin_mushrooms, or check the photos below to get a hint of the beauty of the slime molds, and Alison's artistic skill in capturing them.

You can also find Alison on Facebook at AlisonKPollack, and on iNaturalist at alison_pollack.

I love discovering overlooked plants and animals that play outsized roles in the environment. I’m also fascinated by complex systems, especially when they’re easy to observe.

And nothing ticks all three of those boxes better than ants.

One estimate says that for every human on earth, there may be as many as 2.5 million ants. And these ants form complex societies with unique roles. They communicate in mysteriously complex ways, and can range in size from almost microscopic to an inch and a half long.

Ants can build colonies in acorns, hollow twigs, leaf baskets, massive tree branches, and of course, in the ground. The largest super colonies stretch for hundreds of miles - and by the way, you can find such super colonies in California and in southern Europe. They can farm fungi, and ranch aphids.

My guest today helped unveil all of this and more. Chloe Jelly is a graduate researcher at Cornell University in the Moreau lab. She particularly enjoys outreach, which made her an ideal guest for today’s episode.

People sometimes say that viruses and microbes rule the world, but after today’s discussion, you’ll see that ants aren’t very far behind.

Find Chloe on her website, at the Moreau Lab, and on BlueSky.

Check our Full Show Notes for photos and videos that were discussed today.
