    Lichens have high tolerance to harsh environmental conditions, where lichen symbiont interactions (e.g. myco- and photobionts) may play a crucial role. The characterization of fungal-algal association patterns is essential to understand their symbiotic ...
  • Sævarsson, Elvar Smári (University of Iceland, 2018-11)
    Background: The academic performance of children has been correlated with their future educational attainment and health and has therefore been viewed as a public health concern. Physical activity and cardiorespiratory fitness are known to exert many ...
