Plants and climatic stress

Learning objectives

 

 

  • perhaps be surprised that certain organisms like what humans consider stressful
     
  • acknowledge that the common "stress and limitation" concept is problematic
     
  • adopt a less anthropocentric view of life in the cold
     
 

  • which physical constraints may impair alpine plant life at times
     
  • what the critical thresholds of such influences are
     
  • under which conditions alpine plants are at risk of being damaged by climatic extremes
     

 

  • the mechanisms of frost tolerance
     
  • the circumstances under which heat may become critical
     
  • why and when excess solar radiation can be problematic
     
 

  • distinguish between conditioning and destructive climatic deviations from optimality
     
  • estimate the risk of damage by extreme events in alpine plants
     
  • explain how such effects operate and how plants can cope with these constraints
