Abstract

1. In central Siberia Pinus sylvestris forests and bogs are common elements of the landscape and they show different functional behaviour in terms of energy and carbon exchanges. 2. The two ecosystems show a remarkable difference in energy dissipation, with average Bowen ratios of 0.6 and 2.9, respectively. 3. The alternation of bogs and forests with different energy partition at the surface could affect rainfall distribution and the disturbance regimes (lightening and fires) and drive the ecology of such a complex landscape. 4. During summer, water shortage and poor nutrient conditions in the soil heavily affect carbon exchange rates of the regenerating forest (- 7.7 mmol m(-2) day(-1)). Consequently the bog becomes a significant dominant carbon sequestration element of this particular landscape with higher rates of carbon uptake (- 104.2 mmol m(-2) day(-1)). [References: 22]
