  1. 11. Sink or source? : uncertainties in large scale model predictions of forest soil organic carbon dynamics

    Författare :Carina Ortiz; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Soil organic carbon (SOC) is the largest terrestrial carbon pool and small changes in this pool may affect the global carbon balance, especially atmospheric concentration of CO2. Within the context of climate policy, the quantification of these changes is important, as pool changes may affect a country's national greenhouse gas budget. LÄS MER

  3. 12. “Dr Jekyll and Mr Hyde?” : Abuse of potent benzodiazepines, exemplified by flunitrazepam, in mentally disordered male offenders

    Sammanfattning : Flunitrazepam (FZ) is an example of a sedative-hypnotic benzodiazepine whose pharmacokinetic properties include a rapid onset of action and an intermediate duration of action. It has a high affinity to central benzodiazepine receptors and affects them profoundly. LÄS MER

  4. 13. Greenhouse gas fluxes from drained peatland : Measurement techniques and management impacts

    Författare :Hannes Keck; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Agricultural use of drained peatlands has significant implications for national greenhouse gas (GHG) emission inventories. Once drained, peatlands emit large amounts of carbon dioxide (CO2), may become small methane (CH4) sinks and, with nitrogen fertilisation, may emit large quantities of nitrous oxide (N2O). LÄS MER

  5. 14. Boreal vegetation responses to forestry as reflected in field trial and survey data

    Författare :Johan Bergstedt; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Logging; boreal forest; selective cutting; scarification; ground-layer flora; survey data;

    Sammanfattning : This thesis had two objectives: the first objective was to evaluate the response of forest ground vegetation to selected forestry operations, i.e. cutting of different intensities and scarification; the second objective was to compare the use of survey data in vegetation research with that of more traditional research using field trials - i.e. LÄS MER

  7. 15. Growth trends and site productivity in boreal forests under management and environmental change: insights from long-term surveys and experiments in Sweden

    Författare :Alex Appiah Mensah; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Under a changing climate, current tree and stand growth information is indispensable to the carbon sink strength of boreal forests. Important questions regarding tree growth are to what extent have management and environmental change influenced it, and how it might respond in the future. LÄS MER
