Data from CzechGlobe ecosystem stations helped to clarify the relationship between temperature and respiration of ecosystems

Respiration of ecosystems is a major component of the global carbon cycle. Respiration is strongly dependent on air and soil temperature and determines whether terrestrial ecosystems will be a carbon sink or carbon source. A study, whose results were published by the journal Nature Ecology & Evolution, by an international team of scientists from 27 institutions around the world including the Global Change Research Institute CAS – CzechGlobe, focused on describing the respiration of ecosystems in a global context.

The results revealed the thresholds of the global relationship of ecosystem respiration to air and soil temperature and confirmed that the respiration of ecosystems in cold climate zones depends significantly more on temperature than in warm (tropical) zones, where respiration of ecosystems depends more on water and nutrient availability.
