Giant kelp forests at critical light thresholds show compromised ecological resilience to environmental and biological drivers

  • Kelp forests have been impacted worldwide but with few generalities between cases.
  • Light defines photoautotroph distribution, but thresholds are poorly defined.
  • Here I explore the impacts of gradients of suspended sediments on kelp bed ecology.
  • Identified thresholds of light caused a shift in a range of ecological metrics.
  • Kelps and fucoids responded to similar thresholds but through different mechanisms.
