Ecological Roles and Adaptations

Like other mosses, P. lacerifolia plays important ecological roles:

  • Moisture retention: Its mat-like growth traps and holds moisture, helping regulate humidity in the forest understory.
  • Nutrient cycling: It takes up nutrients from the atmosphere and releases them back to the ecosystem upon decomposition.
  • Microhabitats: It provides shelter and foraging grounds for tiny invertebrates.

P. lacerifolia has adaptations for its epiphytic lifestyle:


Plagiochila lacerifolia Steph. may be small, but it is a fascinating and ecologically valuable moss. From its lacerated leaves to its global distribution, this species exemplifies the incredible diversity within the Plagiochilaceae
