Elizabeth Hadly has been studying biodiversity in Yellowstone National Park for 30 years. Accompanied by biologist Sean Carroll, she demonstrates different ways in which climate change is impacting the park’s ecosystems. Use this in the classroom as a real-world example of food webs and how they can be disrupted.

LAST WEEK FOR ME LETS GOOOOO
Hol up- she touched that with her hands- no gloves? BYE-
the way she just picked up the poop with HER BARE HANDS has me shook
OKAY the way she just casually picked up the poop is kinda sus
I'm shook as well by the way she picked up the poop with no gloves. To make it worse, she was breaking it and feeling every part. Disgusting lol.
damn she really just grabbed that bear poop huh. iconic
who watches this for fun?
Great video. I notice that the video was made 8 years ago. Climate change has only gotten worse.
I think some of you freshman/soph haven't learned that scat, aka poop, is HIGHLY more efficient in animals than people for some species. A bear, being a key-stone species in Yellowstone, has to rely on every meal as if it is their last. The absorption rate of a bear's large intestine pulling water out of fecal matter is far greater than humans. Trust me, it's just warm seeds and berries that time of the year, this is right before hibernation. AKA they are conserving energy and not hunting. It's not like picking up human feces with different microbes or E. Coli.
When you guys get to your jr/sr year and start doing internships, I promise you, this will happen in the backcountry by your internship leader. Then you will do it to your future students. Something I hope to help do, pass on knowledge, and random facts about bear scat! Good luck everyone working on their studies.
Need the song from very beginning… anyone know?
Now look at Yellowstone only 8 years later.
