plays a crucial role in its ecosystem. It contributes to soil formation and moisture retention, creating favorable conditions for other plant species to thrive. Additionally, this moss serves as a habitat and food source for various microscopic organisms, further enhancing biodiversity.
One of the remarkable adaptations of Riccia sorocarpa var. heegii Schiffn. is its ability to survive desiccation. During periods of drought, it can enter a dormant state, reviving once favorable conditions return. This resilience allows it to colonize and thrive in challenging environments.

Case Studies/Examples

In a recent study conducted in a temperate forest, researchers observed the rapid colonization of Riccia sorocarpa var. heegii Schiffn. on disturbed soil areas. This moss played a crucial role in stabilizing the soil and facilitating the establishment of other plant species, contributing to the overall ecosystem recovery.
