  1. 11. Endophytic fungi in living trees - are communities affected more by tree species, tree age, or geographic origin?

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Lisen Källman; [2022-08-16]
    Keywords : ;

    Abstract : Endophytic fungi are ubiquitous in living vascular plants and have been identified in most terrestrial environments. The endophytes may have various ecological roles such as commensals, symbionts and latent invaders. READ MORE

    Keywords : klimatförändringar; återplantering; lövskogsbruk;

    Abstract : Lövskogarna var för 200 – 300 år sedan överexploaterade i södra Sverige och förekommer idag främst i mindre och fragmenterade områden. Efterfrågan på barrsågtimmer från industrierna steg och på de tidigare lövbevuxna markerna planterades istället gran och tall. READ MORE

  4. 13. Identification of spectral features differentiating fungal strains in infrared absorption spectroscopic images

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Dejan Stancevic; [2022]
    Keywords : Physics and Astronomy;

    Abstract : There are many unknowns regarding the interaction between fungi and their surroundings. In this project, we took a closer look at hyperspectral images of several fungal strains on two different substrates. The project mainly consisted of developing a code for the classification of fungal strains and the extraction of information from it. READ MORE

    Abstract : Boreal forests are particularly vulnerable to climate change, experiencing a much more drastic increase in temperatures and having a limited amount of more northern refugia. The trees making up these vast and important ecosystems already had to adapt previously to environmental pressures brought about by the repeated glaciations during past ice ages. READ MORE
