Increasingly severe ocean warming and marine heatwave events are driving declines in habitat-forming kelps worldwide. Direct mortality from extreme temperatures, coupled with destabilization of kelp forest communities, commonly trigger ecological community shifts from dominant kelp forests to an algal turf dominated state. Opportunistic algal turf species are more resilient to warming and lack the fundamental structure of kelp forests, and thus reduce ecosystem services and biodiversity. Once in place, algal turf communities contain ecological feedback mechanisms, diminishing kelp recruitment, and potential recovery. The various feedback mechanisms and ecological thresholds that maintain or drive community shifts between kelp forest and algal …
