  1. 11. Autumn water sources for understory vegetation and fungi in a boreal forest : an evaluation using stable isotopes

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

    Author : Javier Segura; [2013]
    Keywords : Ericaceous shrubs; fungi; Pinus sylvestris; rain event; soil profile; water stable isotopes;

    Abstract : Understory vegetation and fungi are regarded as important ecological drivers of processes like productivity and nutrient cycling in boreal forests. Whilst those processes are linked to soil water content, relatively little is known about the sources of soil water for these forest components. READ MORE
