Ecological Role

  • Bryum argenteum is an important component of Biological Soil Crusts (BSCs) in some desert environments.

Genetic Information

  • The RAPD (Random Amplified Polymorphic DNA) technique has been used to assess genetic diversity in Bryum pseudotriquetrum.

Interactions with Other Organisms

  • Bryum argenteum depends on epiphytic bacteria for freezing protection in Antarctic environments.
  • Waitea circinata is an important fungal pathogen that affects Bryum argenteum on amenity turfgrasses.

Quirky Facts
