Grizzly bears in the contiguous United States have been taken off — then put back on — the endangered species list twice since they were first labeled as threatened almost 50 years ago. Now, the issue is on the table again. Today, we get into the complicated science behind grizzly recovery, how humans have sliced up their habitat and what it will take to stitch that habitat back together again.

Researchers glued cameras and tracking instruments to small pieces of neoprene, that they then glued to the fur of the sea lions

Scientists attach video cameras to sea lions to map the ocean floor

How do you study unmapped areas of the ocean and identify critical habitat for an endangered species? You include the study animal in the scientific process! Researchers from the University of Adelaide fitted endangered Australian sea lions with cameras and tracking devices to better understand where they spent their time. The information could help scientists protect critical sea lion habitat and could give researchers a new tool for mapping the ocean.
