Understanding temperature-sensitive trophic level interactions has garnered interest in the context of current global warming trends. We examine tri-trophic (resource-consumer-predator) and investigate bi-stable dynamics; with one favourable regime sustaining oscillations all levels, while other unfavourable involves predator population collapse. Incorporating effects through explicit time dependence model parameters, we demonstrate that attractor transitions a sequence dynamics, including chaos, transient ultimately, loss bi-stability, as temperature rises. Such can occur within narrow range rise, if biological ecological rates are made dependent. This collective influence traits on system is termed ‘aggregated B-tipping’. As result aggregated B-tipping, threshold manifests differently tropical versus temperate biomes, facing distinct risk extinction relatively modest rise biomes. These findings support hypothesis systems more vulnerable to warming, despite experiencing lower rise.
