Lichen on a serpentine rock outcrop at Sedgwick Reserve in Santa Barbara County. Lichens are symbiotic partnership between a fungus and photosynthetic green alga, and/or cyanobacteria. Lichen live in high-stress environments where they are exposed to extreme temperatures, high UV radiation, and desiccation. In this issue, students studied the factors contributing to lichen diversity and distribution in a harsh serpentine environment. Image: Tim Sisneros
