Adaptation to extreme environments
My research focuses on the moss genus Syntrichia, whose species are key primary producers in biological soil crusts (biocrusts), complex communities of bryophytes, lichens, and other microorganisms living on the soil surface of drylands. These small-but-mighty communities are ecologically critical, performing a suite of essential ecosystem services. Mosses and other biocrust organisms have evolved vegetative desiccation tolerance—the ability to equilibrate to dry air, pausing all metabolic activity until rehydration—making them an excellent model system for studying stress tolerance mechanisms and adaptation to the desiccating and irradiating conditions of terrestrial life.
