Ecosystem respiration in a heterogeneous temperate peatland and its sensitivity to peat temperature and water table depth

Popis výsledku v původním jazyce

Background and aims Ecosystem respiration (R eco ) is controlled by thermal and hydrologic regimes, but their relative importance in defining the CO2 emissions in peatlands seems to be site specific. The aim of the paper is to investigate the sensitivityof R eco to variations in temperature and water table depth (WTD) in a wet, geogenous temperate peatland. Methods The CO2 fluxes were measured using chambers. Measurements were made at four microsites with different vegetation communities every 3 to 4 weeks during the period 2008?2009, 2 years with contrasting WTD patterns. Models were used to examine the relative response of each microsite to variations in peat temperature and WTD and used to estimate annual total Reco. Results Temporal variations inReco were strongly related to peat temperature at the 5 cm depth. However, two of the microsites did not show any significant change in this relationship while two others showed contrasting responses including an increase and decrease in
