Persistence of epiphytic lichens along a tephra-depth gradient produced by the 2011 Puyehue-Cordón Caulle eruption in Parque Nacional Puyehue, Chile

Lichens, symbioses between fungi and algae or cyanobacteria, are diverse and abundant in humid temperate forests in mountain ranges such as the Andes. They are also sensitive to changes in atmospheric conditions. We suspected lichens would show die back as a result of tephra fall from the 2011 Puyeh...
