Species and composition of tundra meadows ...

Observations of hummock and string-like microrelief features were made in High Arctic hydric meadows. Thermal shearing of thick bryophyte mats, and subsequent roll back during spring flooding appears to be one way in which this topography is formed. Hummocky and non-hummocky (flat) meadows show dist...

Description
Summary:Observations of hummock and string-like microrelief features were made in High Arctic hydric meadows. Thermal shearing of thick bryophyte mats, and subsequent roll back during spring flooding appears to be one way in which this topography is formed. Hummocky and non-hummocky (flat) meadows show distinct floristic differences which may in part be due to observed differences in temperature, nutrient concentrations and moisture relations. ... : Supplement to: Barrett, Paul (1979): Interaction of Bryophytes and Thermal Cracking in the Genesis of Hummock and String-like Microtopography in High Arctic Tundra Meadows.
