  1. 1. Inverkan av trädkaraktärer på överlevnad och tillväxt hos 17 trädarter i orörd tropisk regnskog på Borneo

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management; SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Magnus Nilssen Klinga; Cassandra Ramstedt; [2018]
    Nyckelord :Dipterocarpaceae; life-history traits; mortality; relative growth; trade-off; ingrowth rate;

    Sammanfattning : Träd och växter har genom tiderna utvecklat olika strategier för att konkurrera om överlevnad och reproduktion. Att vara konkurrenskraftig ur en ekologisk aspekt medför ofta en trade-off som gör arten mindre konkurrenskraftig ur en annan. LÄS MER

  3. 2. Stand dynamics and carbon stock in a sal (Shorea robusta C.F. Gaertn) dominated forest in Southern Nepal

    Uppsats för yrkesexamina på avancerad nivå, SLU/Southern Swedish Forest Research Centre

    Författare :Patrik Ulvdal; [2016]
    Nyckelord :forest dynamics; S. robusta; carbon stock; community forestry; forest growth;

    Sammanfattning : There is a lack of knowledge about the stand dynamics and carbon storage in forests dominated by Shorea robusta C.F. Gaertn (fam. Dipterocarpaceae) in southern Nepal, especially in forests managed by local communities. LÄS MER

  4. 3. Restoration of degraded tropical rainforests through gap and line planting : effects on soil and light conditions and seedling performance

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Lukas Holmström; [2016]
    Nyckelord :enrichment planting; seedling survival; seedling height; dipterocarp; light; stödplantering; plantprestanda; överlevnad; höjd; dipterocarp; ljuskvantitet;

    Sammanfattning : Enrichment plantings are a common way to restore structures and diversity lost through degradation of tropical rainforests. Large areas are degraded every year, and although disturbance over large areas seldom are homogenous, few, if any studies have compared effects of enrichment planting treatments in forests with varying degradation.

  5. 4. Degradation and restoration method interact to affect the performance of planted seedlings in tropical rainforest restoration : evidence from plant functional traits

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Forest Ecology and Management

    Författare :Julia Mellåker; [2016]
    Nyckelord :Dipterocarpaceae; enrichment planting; INIKEA; secondary rainforest; hjälpplantering; sekundär regnskog;

    Sammanfattning : A common action to improve or save biodiversity in the tropics is restoration of degraded rainforest. To understand the complex ecological structures of the forest and adapt the restoration actions after them, studies have focused on characterizing species with functional traits. LÄS MER

  7. 5. Restoring biodiversity in degraded secondary rain forest in Sabah, Malaysia : natural regeneration of trees after restoration treatments

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Sara Waern; [2015]
    Nyckelord :skogsbrand; selektiv avverkning; Dipterocarpaceae; assisterad naturlig föryngring ANR ; forest fire; selective logging; Dipterocarpaceae; assisted natural regeneration ANR ;

    Sammanfattning : Many tropical rain forests has been lost or degraded as a result of human activities and environmental factors. Since the level of biodiversity is high in the tropics, maintaining these areas is of great importance. Forests like these are often assumed to benefit from forest restoration and rehabilitation.
