Global Warming Can Lead to Depletion of Oxygen by Disrupting Phytoplankton Photosynthesis: A Mathematical Modelling Approach

摘要: We consider the effect of global warming on coupled plankton-oxygen dynamics in ocean. The net oxygen production by phytoplankton is known to depend water temperature and hence can be disrupted warming. address this issue theoretically considering a mathematical model system. generic account for variety biological factors. first show that sustainable only possible if rate above certain critical value. This result appears robust details parametrization. then that, once zooplankton taken into (which consume feed phytoplankton), system stable within intermediate range (i.e., not too low high). Correspondingly, we conclude sufficiently large increase likely push out safe range, which may ocean anoxia even depletion. generalize taking environmental stochasticity paradoxically, probability depletion decrease with an
