Anthropogenic climate change is causing marine trophic pyramids to undergo rapid species and trophic reshuffling. While previous mesocosm studies have shown how ocean acidification (OA) and warming can change trophic architecture by driving bottom-up and top-down processes, I will use in situ experiments at CO₂ seeps and warming hotspots in New Zealand and Japan to observe how the direct and indirect effects of these climate stressors will reorganise size-, biomass-, productivity-, and nutritional-based marine food webs. This study will reveal the future of marine trophic pyramids under climate change.
