Carbon balance is the sum of different contributions either emitters or sequesters and is also affected by anthropogenic effects and disturbances. This thesis focus on different components of the carbon balance in the forest ecosystems. This work tries to answer three questions concerning carbon fluxes. The first question is regarding the comparison of carbon balance between managed and unmanaged montane spruce forest after windthrow event. The second question asks if there is a different response of soil respiration between infested and uninfested montane spruce forest after bark beetle attack and also within elevation gradient. And the last question wants to know the difference in soil respiration and its components between different forest types. The study highlights important findings as follows: managed forest became the carbon sink than the spruce stand which was left unmanaged and trees were not logged after windthrow. This was due to decaying left wood and a worse ratio between assimilation rates and respiration of successional vegetation at unmanaged site. Significantly higher soil respiration was measured at the infested spruce stand by the bark beetle. Different elevations showed different soil respiration rates showing decreasing rates with increasing elevation in one year. Among four forest types, coniferous forest showed the highest soil respiration rates and also the highest share of heterotrophic component. The main determinant of SR was attributed to soil moisture and its interaction with soil temperature. This thesis reveals that this topic of carbon balance in the forest ecosystem is complex due to many factors and variables affecting its dynamics. 336 $a Elektronický zdroj. 608 $3 sldk_un_auth*h005061 $a dizertácie $X dissertations 610 1-
