  4. 2. Modelling soil temperature and carbon storage changes for Swedish boreal forests

    Author : Magnus Svensson; KTH; []
    Keywords : SPAC; soil surface energy balance; Norway spruce; canopy; LAI; climate; nitrogen; CoupModel;

    Abstract : With the use of a process-orientated ecosystem model andmeasurements conducted at different Swedish coniferous forestsites, abiotic and biotic interactions between tree and soilwere identified and related to governing factors. Two differentmodelling approaches to describe soil temperatures at two sitesincluding hydrological transects were tested (I). READ MORE

  6. 4. Aspects of regeneration in tropical secondary forests of Northeast Borneo affected by selective logging, El Niño-induced drought and fire

    Author : Eva Romell; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : A large proportion of the world´s tropical rainforests are today secondary forests, a term encompassing forests in various degrees of degeneration. For the main traits of old-growth forests´ structures, species composition and ecosystem functions to recover, regeneration of non-pioneer tree species is essential. READ MORE

  7. 5. Small-scale pattern and mobility of plant species in Alvar grassland
