  2. 11. The role of microclimate for the performance and distribution of forest plants

    Author : C. Johan Dahlberg; Kristoffer Hylander; Johan Ehrlén; Jason D. Fridley; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; performance; microclimate; spatial scales; continental; landscape; distribution patterns; distribution limits; phenology; vegetative development; reproductive development; vital rates; population growth rate; vascular plants; bryophytes; distribution modelling; Plant Ecology; växtekologi;

    Abstract : Microclimatic gradients may have large influence on individual vital rates and population growth rates of species, and limit their distributions. Therefore, I focused on the influence of microclimate on individual performance and distribution of species. READ MORE

  4. 12. Linking plant population dynamics to the local environment and forest succession

    Author : Johan Petter Dahlgren; Johan Ehrlén; Ove Eriksson; Mark Rees; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Actaea spicata; Forest herbs; Forest succession; Integral projection model; Plant demography; Plant phenology; Population dynamics; Pre-dispersal seed predation; Seed mass; Soil potassium; Specific leaf area; Terrestrial ecology; Terrestisk ekologi; Plant Ecology; växtekologi;

    Abstract : Linking environmental variation to population dynamics is necessary to understand and predict how the environment influences species abundances and distributions. I used demographic, environmental and trait data of forest herbs to study effects of spatial variation in environmental factors on populations as well as environmental change in terms of effects of forest succession on field layer plants.

  5. 13. Physiological integration and morphological plasticity in extensive clonal plants

    Author : Tina D'Hertefeldt; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant ecology; Maianthemum; Carex; Clonal plants; tracers; Växtekologi;

    Abstract : Clonal plants show a large variation in physiological integration, i.e. the translocation of resources among ramets within the clone. READ MORE

  6. 14. 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.
