 Population persistence in the face of climate change and competition: A battle on two frontsD. Scott Rinnan Ecological Modelling, 2018, vol. 385, issue C, 78-88 Abstract: Many species undergo significant shifts in population distribution in response to changes in climate. This response can introduce a species to new competition from invasive organisms, or influence the dynamics of an otherwise balanced ecosystem. How can a species ensure its own survival while dealing with both interspecific competition and the effects of climate change? We examine a two-species discrete-time, continuous-space population model to determine conditions for coexistence and criteria for persistence in a changing climate. Our analysis suggests that the cost of keeping pace with climate change can weaken the ability of a species to compete with others, and that climate change has the capacity to shift the stable-state solution of the population model. These effects are somewhat mitigated by niche differentiation, with the potential for habitat considered inhospitable to one species to provide refuge for the other.
