  1. 21. The effects of site preparation on carbon fluxes at two clear-cuts in southern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Liisi Nogu; [2014]
    Keywords : eddy covariance; soil CO2 flux; site preparation; physical geography; geography; chamber measurements; Earth and Environmental Sciences;

    Abstract : Clear-cutting is a common forest management practice. It alters the carbon balance of forests by eliminating photosynthesis through canopy removal and affecting autotrophic and heterotrophic respiration. In Sweden, almost 200 000 ha of forest is clear-cut every year and site preparation is carried out on more than 80% of it. READ MORE

  2. 22. Biofilm formation in a large sized experimental set up of a drinking water distribution system consisting on various pipe materials

    University essay from Lunds universitet/Examensarbeten i molekylärbiologi

    Author : Harald Franzén; [2013]
    Keywords : Biology and Life Sciences;

    Abstract : Abstract In water distribution systems newly exposed areas, such as newly laid pipes are subjugated to biofilm growth. This growth have been associated with public health problems and has lead to the water treatment facilities seen today. READ MORE

  3. 23. Estimating contemporary methane emissions from tropical wetlands using multiple modelling approaches

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Shubangi Lamba; [2012]
    Keywords : LPJ-GUESS; uppskalning; modellering; tropisk våtmark; metanutsläpp; methane emissions; tropical wetlands; modelling; upscaling; physical geography; ecosystem analysis; Earth and Environmental Sciences;

    Abstract : Estimating contemporary methane emissions from tropical wetlands using multiple modelling approaches Methane gas makes a significant contribution to the greenhouse effect happening on the planet. In modern times, natural wetlands are the biggest source of methane gas as compared to other sources of natural origin. READ MORE

  4. 24. Spatial heterogeneity of soil CO2 efflux at ADVEX site Norunda in Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Abstract : This study investigates the spatial variation in soil carbon dioxide (CO2) efflux in a boreal mixed forest mainly dominated by Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies L.) in the ADVEX expermental site in Norunda, in central Sweden. READ MORE

  5. 25. Variation i temperaturrespons (Q10) vid nedbrytning av biopolymerer

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Anna-Karin Marklund; [2011]
    Keywords : organic matter; biopolymers; decomposition; temperature response; Q 10; microorganisms; physiologic status;

    Abstract : Nedbrytningshastigheten för organiskt material i marken kan komma att förändras vid varmare klimat. I dagsläget råder dock oenighet om hur nedbrytningen av organiskt material kommer att reagera på förändrade temperaturer; forskningsrapporter pekar åt olika håll. READ MORE
