Temperature responses of photosynthesis and respiration in a sub-Antarctic megaherb from Heard Island

Schortemeyer, Marcus; Evans, John; Bruhn, Dan; Bergstrom, Dana M; Ball, Marilyn


Understanding the response of sub-Antarctic plants to a warming climate requires an understanding of the relationship of carbon gain and loss to temperature. In a field study on Heard Island, we investigated the responses of photosynthesis and respiration of the sub-Antarctic megaherb Pringlea antiscorbutica R. Br. to temperature. This was done by instantaneously manipulating leaf temperature in a gas exchange cuvette on plants adapted to natural temperature variation along an altitudinal...[Show more]
