Abstract

This study evaluates how mixed kelp communities in an Arctic fjord respond to combined future stressors associated with climate change, including warming, freshening, and reduced light. Using a two-month mesocosm experiment, it shows that summer net productivity remains comparatively tolerant across treatment conditions, while light availability exerts the strongest control on net community production.
