and rainforests. Macrothamnium hylocomioides prefers shaded, moist environments with high humidity levels.
Ecological Roles and Adaptations
Like other mosses, Macrothamnium plays a vital role in its ecosystem:
- Water retention: Its dense growth helps retain moisture in the environment.
- Microhabitat creation: It provides shelter for small invertebrates.
