Lacarella et al. 2024 salmon stream temperature under climate change

From Salish Sea Wiki

Iacarella, J.C., Chea, R., Patterson, D.A. and Weller, J.D., 2024. Projecting exceedance of juvenile salmonid thermal maxima in streams under climate change: A crosswalk from lab experiments to riparian restoration. Freshwater Biology.


  • For British Columbia streams.
  • Focused on species that rear for one summer in freshwater before outmigration.
  • Authors reflect that lab-based temperature impact analysis does not reflect field conditions, particularly daily variation (diel variation) and selection of cold-water refugia.
  • They propose methods for processing stream temperature data to describe relative risk focusing on a metric that is the mean between mean weekly average temperature and the seven day average of daily maximum as an indicator of risk to fish.
