Mojave and Sonoran Deserts, California

As the human population gets more connected, animal populations become more separated.

Recently, biologists studied 27 groups of desert bighorn sheep, which live on the rocky mountains of the Mojave and Sonoran deserts. The scientists found that sheep populations nearest highways and cities were the most genetically inbred.

The study confirms what scientists have long suspected—that bighorns cannot cross major fenced highways and other urban barriers to join new groups. Without adequate gene flow, the health—and existence—of the bighorn sheep are at risk.
