How species and ecosystems respond to the threatened environmental conditions are attracting phenomenon facing ecologists. One can expect species fight against these forces to get rid of extinction, i.e., species tend to adapt genetically or move to a new environment to resilience against extinction. In this paper, this problem is focused theoretically by considering a coupled of the oxygen-plankton model where planktons’ habitat changes and beachhead as a response to climate change. Hence, the dynamics of the oxygen-plankton model is considered assuming the spatial gradient of the growth rate of oxygen, in concern with altered sea surface temperature. It is observed that there exists a relationship between the slope of the gradient and the beachhead at which the oxygen-plankton system can stably survive, which can be defined by a simple function that separates the areas of extinction and persistence. Findings reveal that environmental gradient is an alternative way for species to create a new habitat and sustain the species persistence. Therefore, in this paper, it is shown that, in theory, the recovery of plankton extinction and oxygen depletion under climate change can be achieved by adding a spatial gradient.
