In our first case file, we find out how environmental DNA can be used to assess the health of an entire ecosystem—all by looking at some of that ecosystem’s smallest inhabitants: amphipods. It’s a grand idea, but the DNA of these tiny shrimplike critters is as elusive as the creatures themselves. Will researchers find a way to detect the disappearing DNA and crack this case?
This episode is part of our series Nature Files. From invasive crabs to lost whales, tapping into the world of environmental DNA can be the key to solving some of nature’s biggest riddles. Join us as we crack the code on nature and unlock mysteries in The Nature Files.
