plays a crucial role in its ecosystem. These mosses act as pioneers, colonizing bare surfaces and paving the way for other plant species to establish themselves. They also contribute to soil formation and moisture retention, creating favorable conditions for a diverse array of organisms.
One of the remarkable adaptations of Frullania is its ability to withstand desiccation. During periods of drought, the moss can curl up and enter a dormant state, conserving moisture and reviving once favorable conditions return. This resilience allows it to thrive in environments where water availability is unpredictable.
