Distribution and Habitat
Dactylina beringica is found in the American Arctic and extends from the USSR across the Bering Strait into North America. It is also mentioned in the context of West Greenland and lichen diversity on isolated Bering Sea islands. This species is associated with the Bering Land Bridge region, including areas like the Seward Peninsula and the Bering Strait.
Ecological Role
This lichen is a component of tundra ecosystems, often found in lichen tussock tundra and erect dwarf-shrub communities on dry, acidic slopes.
Morphological Characteristics
Dactylina species are macrolichens, exhibiting stout growth habits. They can be fruticose (shrub-like).
Interactions with Other Organisms
Dactylina lichens coexist with other lichens, bryophytes, algae, and fungi in the Bering Strait region. They are also found in association with specific vegetation types and substrates, with lichen species composition being related to substrate pH.
