Below are screenshots of my twitter thread on the collaboration of zoo staff and scientists to understand metabolic rates and energetics in polar bears by training zoo-housed bears to inform us on their wild counterparts! It includes a lot of gifs, videos, and images that I think enhance the thread, so I recommend you check it out on my twitter, @Tori__Roeder. If you feel so inclined, you can follow me for animal and ecology content, though predominantly mammals and zoos.
