The research was conducted to better understand how salamanders procreate and how to better preserve them and conserve their habitats.
Researchers looked at two types of mole salamanders for their study. One type of salamander studied was all-female and reproduces by cloning or borrowing sperm males leave on twigs and leaves. The other type of salamander studied mates in a more traditional manner, according to the university.
Genetic information collected from wetlands lined up with treadmill tests as the salamanders that mate in a more traditional sense traveled twice as far from their birthplace as all-female cloning salamanders.
