Arctic and alpine cushion plant form and orientation increases heat gain from sunlight and the surro

Description
This summarizes the processes involved in thermal regulation by a cushion plant. As a consequence of these processes, cushion plants are often warmer than the surrounding air and than plants with other growth forms. For example, Yngvar Gauslaa (1984), has documented the thermal consequences of the cushion growth form. He found that while the temperature of plants with an open growth form closely matches air temperature, the temperature of cushion plants can be over 10°C higher than air temperature.
