David Barnes et al. observe spatial competition of fauna on artificial substrata in the West Antarctic Peninsula and found that while 1°C warming increased the probability, density, and complexity of spatial competition, competition did not increase with 2°C warming. These results help improve understanding of responses of competitive pairings between species to global physical change and suggest an increase in competition intensity with moderate warming seems likely.
