  1. 1. Rooting for forest resilience : Implications of climate and land-use change on the tropical rainforests

    Författare :Chandrakant Singh; Ingo Fetzer; Lan Wang-Erlandsson; Ruud van der Ent; Axel Kleidon; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; forest dynamics; human influence; land-use change; rainforest tipping; remote sensing; resilience; root zone storage capacity; tropical forests; vetenskap om hållbar utveckling; Sustainability Science;

    Sammanfattning : Tropical rainforests in the Amazon and Congo River basins and their climate are mutually dependent. Evaporation from these forests help regulate the regional and global water cycle. Furthermore, these rainforests themselves depend on precipitation to sustain their structure and functions. LÄS MER

  3. 2. The forgotten forest : on thinning, retention, and biodiversity in the boreal forest

    Författare :Julian Klein; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Fennoscandia has had a long history of intensive forest management. It can therefore be regarded a trial zone for other boreal regions which are still largely unaffected by forestry. In Fennoscandia, forestry has resulted in many threatened species and methods that maintain biodiversity have therefore been called for. LÄS MER

  4. 3. Spatial Variation in Near-Ground Radiation and Low Temperature - Interactions with Forest Vegetation

    Författare :Kristina Blennow; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; light interception; hemispherical photograph; growth; forest fragmentation; fluorescence; cold-induced photoinhibition; GIS; view factor; radiative cooling; frost protection; agro-climatic mapping; forest clear-cut; local climate; Microclimate; Physical geography; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

    Sammanfattning : Low temperature has a large impact on the survival and distribution of plants. Interactive effects with high irradiance lead to cold-induced photoinhibition, which may impact on the establishment and growth of tree seedlings. LÄS MER

  5. 4. DYNAMIC MODELLING OF BIOGEOCHEMICAL PROCESSES IN FOREST ECOSYSTEMS

    Författare :Salim Belyazid; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Naturvetenskap; marklära; Silviculture; forestry; forestry technology; Skogsvetenskap; skogsbruk; skogsteknik; Natural science; Lantbrukshydrologi; Soil Science; agricultural hydrology; Växtekologi; Forest Soil Acidification; Plant ecology; Plant biochemistry; Forest Growth; Vegetation biodiversity; Carbon Sequestration; Nitrogen Leaching; Miljökemi; Dynamic Modelling; Växtbiokemi; Environmental chemistry;

    Sammanfattning : Forests in Sweden are undergoing rapid and considerable changes regarding both management methods and environmental conditions. To understand the effects of these changes and to be able to predict impending changes in forest ecosystems, a holistic understanding of the processes governing the ecosystem is needed. LÄS MER

  7. 5. Forest-savanna transitions: Understanding adaptation and resilience of the tropical forest ecosystems using remote sensing

    Författare :Chandrakant Singh; Ingo Fetzer; Lan Wang-Erlandsson; Ruud van der Ent; Stefano Manzoni; Udita Sanga; Vivian Ribeiro; Stockholms universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Environmental Sciences; miljövetenskap; Ecology and Evolution; ekologi och evolution; Hydrology; hydrologi;

    Sammanfattning : Climate and deforestation-induced changes in precipitation drive tropical forest-savanna transitions. However, precipitation alone provides a superficial understanding of the underlying mechanism behind these transitions. This is because our knowledge of how vegetation responds to changes in hydroclimate is fragmented. LÄS MER
