  4. 2. Interactions between climate, natural disturbances, and regeneration in boreal and hemi-boreal forests

    Author : Igor Drobyshev; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conservation strategies; Plant ecology; Växtekologi; taiga; seasonal climate; shoot increment; larch; reconstruction; human; canopy gap; fire history; boreal; natural disturbances; dendrochronology;

    Abstract : Natural disturbance is an important driving force of community dynamics in many forest types around the globe. Understanding spatial and temporal properties of disturbance events in the present and in the past is important in formulating the nature conservation strategies as well as for the modeling of climate and human impacts on forest vegetation.
