 ===Carbon dynamics===
-IMAGE-LPJmL covers the carbon cycle processes, and tracks all carbon fluxes between the atmosphere and the biosphere. Carbon cycle dynamics of the terrestrial biosphere are computed as carbon uptake and release in plants (photosynthesis, autotrophic respiration), transfer of plant carbon to the soil (shedding of leaves, turnover, mortality) and mineralisation of soil organic matter (heterotrophic respiration; see Flowchart). Because these processes are closely related to weather conditions, they are computed in daily time steps.
+IMAGE-LPJmL covers the carbon cycle processes, and tracks all carbon fluxes between the atmosphere and the biosphere. Carbon cycle dynamics of the terrestrial biosphere are computed as carbon uptake and release in plants (photosynthesis, autotrophic respiration), transfer of plant carbon to the soil (shedding of leaves, turnover, mortality) and mineralisation of soil organic matter (heterotrophic respiration; see Figure Flowchart). Because these processes are closely related to weather conditions, they are computed in daily time steps.
 The composition of natural vegetation depends on slower processes, such as the inter-annual and inter-seasonal variability in weather conditions and disturbances, such as natural fires. Thus, vegetation dynamics including competition between plant functional types, mortality, turnover, and fire disturbances are computed in annual time steps.
