Quasi runs for studies, chipmunks, and they keep him on his toes.

I would describe them as Elfin, like, Elf looking.

They have like, really angular faces.

And the pointy ears, they're very zippy.

They're small and they're fast.

So it's like the two things you don't want for something you have to spend a lot of time

looking for and observing.

And they're full of personality.

Quasi's seen first hand over summers of field research, observing their every move.

I do my work up in the Sierra Nevada Mountains of California.

You'll see a chipmunk.

It'll kind of be posted up in a rock and it'll just be really still.

And then it'll just take off like a rocket.

To be more specific, Quasi studies two chipmunks in the Sierra Nevada Mountains, the Lodgepole

chipmunk and the Alpine chipmunk.

Between these two species, he's observed one clear difference.

And so we have these two chipmunks, very similar habitats, very closely related

similar ecologies, but very different responses to climate change.

What makes an animal more likely to be resilient to climate change versus sensitive to climate
