  3. 2. Long-term Nitrogen Deposition and Recovery of Epiphytic Lichens : Concealed memory and implications

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Camille Volle; [2022]
    Keywords : epiphytic lichens; N deposition; boreal forest; recovery; critical load;

    Abstract : Anthropogenic activities have increased nitrogen (N) emissions. However, higher N deposition is associated with negative fallouts in ecosystems, highlighting the necessity to define its critical load (CLO). Lichens, with their lack of roots, stomata, and cuticles, are helpful air pollution indicators and can be used to establish N CLO. READ MORE
