Temperature responses of ecosystem respiration and photosynthesis of tundra mesocosms at low temperatures

Tundra monoliths were used in a mesocosm study to assess the temperature responses of ecosystem respiration and photosynthesis at low temperatures (-15 to + 15 C at 5 C intervals) in controlled environments. Measurements were conducted using closed chamber gas exchange system and syringe sampling of...

Description
Summary:Tundra monoliths were used in a mesocosm study to assess the temperature responses of ecosystem respiration and photosynthesis at low temperatures (-15 to + 15 C at 5 C intervals) in controlled environments. Measurements were conducted using closed chamber gas exchange system and syringe sampling of air injected in an infrared gas analyzer in a gas chromatograph mode. Tundra monoliths were collected at Toolik Field Station, Alaska
