. The leaves are large, ovate to oblong-lanceolate, and strongly plicate, giving the plant a unique and eye-catching appearance.

Global Distribution and Habitat

This remarkable moss species is widely distributed across the Northern Hemisphere, thriving in various regions, including North America, Europe, and Asia. It is particularly abundant in boreal and arctic regions, where it flourishes in wetlands, fens, bogs, and along the margins of lakes and streams. Calliergon megalophyllum Mikut. is well-adapted to these moist and nutrient-rich environments, where it plays a vital role in the ecosystem.

Ecological Roles and Adaptations

Calliergon megalophyllum Mikut. is not just a visually stunning moss; it also serves essential ecological functions. As a bryophyte, it contributes to soil formation, water retention, and nutrient cycling. Its dense mats provide a unique microhabitat for various invertebrates, fungi, and other microorganisms, supporting biodiversity in its surroundings.
Moreover, this moss species exhibits remarkable adaptations that enable it to thrive in its preferred habitats. Its ability to

allows it to survive in wetland environments. Additionally, its plicate leaves help to protect the plant from desiccation and environmental stresses.

Case Studies/Examples

To illustrate the significance of Calliergon megalophyllum Mikut., let’s explore a case study from Siberia. In the vast Siberian peatlands, this moss species plays a crucial role in carbon sequestration and peat formation. Its dense mats contribute to the accumulation of organic matter, which, over time, forms valuable peat deposits. These deposits not only store vast amounts of carbon but also serve as important habitats for various plant and animal species.
