When scientists are trying to conserve a species, its critical for them to know how many of those animals are living in the world. But when you're considering creatures like red-backed salamanders, which spend a lot of time underground, how would you try to count them? 🦎🤔
It turns out, you need tiny "tattoos" and a lot of hands. By counting the ratio of marked to unmarked salamanders in a designated plot, researchers can determine how many salamanders are in an entire forest!
The Smithsonian is part of the Salamander Population & Adaptation Research Collaboration Network (SPARCnet), a group of scientists and educators that studies how different salamander populations are faring across North America. Together, SPARCnet monitors how climate change and land use may impact salamanders.
