Ecomotion Studios has been working with the Ecological Society of America to produce short animated films about some of the most influential papers of modern ecology — they’re calling it “The Animated Foundations of Ecology.” Here’s the film about Robert Paine’s famous experiment in removing the top predator of tidal pool communities, sea stars, which led to dramatically reduced diversity in the other species that shared the pools.
There’s a handful more, including on one of my favorite classic ecology papers, David Simberloff and EO Wilson’s experimental demonstration of the process by which species colonize new habitats. Go check ’em out!

My grandfather, a farmer in rural Virginia, was never much worried about saving endangered species or stopping climate change, or any environmental issue that didn’t directly impact next year’s soybean harvest. But as long as I can remember, he maintained a tiny apartment house on a pole in his back yard — just for purple martins.
Martins are glossy, deep-purple swallows that nest in big colonies. Originally, they used cavities in dead tree trunks and cliffs, but in eastern North America they’re now entirely dependent on human-made birdhouses like my grandfather’s. In a great video, Adam Cole of NPR’s Skunk Bear, talks to some martin landlords, discusses some of the challenges the birds face in modern times, and goes on an expedition to find one of the roosts where they gather in huge flocks before migrating to South America for the winter.
As a follow-up to CJ’s post about hummingbird moths—more generally known as hawk moths—let me recommend this episode of Plants are Cool, Too, which features the work of Chicago Botanic Garden conservation scientist Krissa Skogen. At White Sands National Monument, Skogen tracks the nectar rewards that attract hawk moths, and how far the moths carry pollen.
Here at Nothing in Biology, we are big fans of making stuff up (but, uh, not on the blog… or in our scientific publications… or on our tax returns… or, well, you get the point). So a few of us are thinking of entering some of our fantastical(ly bad) evolutionary theories to the Festival of Bad Ad Hoc Hypotheses. This festival is dedicated to “well-argued and thoroughly researched but completely incorrect evolutionary theory”. To get an idea of what it’s about, see the video below. If you’re in or near the Bay Area or Cambridge, Mass this October, think about checking it out!
We’re big fans of Emily Graslie’s natural history video series The Brain Scoop. The latest episode goes right to the source of the museum specimens that usually take center stage—a fossil hunting expedition.
Watch the whole thing, and you’ll learn some nifty paleontology jargon, like:
“It’s called the 18-inch layer.”
“Is it because it’s 18 inches?”
When he’s not dismantling racist pseudoscience, Chris Smith studies the evolutionary ecology of species interactions. Willamette University sent along a videographer on Chris’s last field trip to study Joshua trees and the moths that pollinate them in central Nevada, and the result is now posted on Vimeo. It’s mainly geared toward showcasing how Willamette undergraduate students participate in the fieldwork, but I’d say it makes the desert look mighty good, too.
Here at Nothing in Biology Makes Sense, we’re fascinated by all the weird, baroque ways that living things influence and coevolve with each other—so Ed Yong’s new TED talk about mind-controlling parasites is right up our alley. Just like his writing—currently on display at National Geographic‘s Phenomena, among many other venues—it’s a compendium of nifty natural history punctuated with highly educational gross-outs and the occasional black-belt level pun.
