Ceratodon antarcticus Cardot plays a crucial role in various ecosystems. It acts as a pioneer species, colonizing disturbed or barren areas and paving the way for other plants to establish themselves. Additionally, this moss is highly drought-tolerant, thanks to its ability to enter a state of desiccation and revive when moisture becomes available.

Case Studies/Examples

One fascinating example of Ceratodon antarcticus Cardot’s resilience can be found in the Dry Valleys of Antarctica. In these extreme environments, where temperatures can plummet to -60°C and precipitation is virtually non-existent, this moss has managed to thrive, demonstrating its remarkable adaptations to harsh conditions.
