Synergistic interactions among growing stressors increase risk to an Arctic ecosystem

K. R. Arrigo, G. L. V. Dijken, et al.

This study leverages the OSIRIS model to reveal how interactions between climate-related stressors in the Chukchi Sea pose a greater risk than acute stressors like shipping. Conducted by a team of experts, the research underscores the importance of incorporating stressor interactions into management strategies to prevent population crashes.

Abstract

Current ecosystem models often treat stressors independently, ignoring potential interactions. This study uses the Ocean System Interactions, Risks, Instabilities, and Synergies (OSIRIS) model to examine stressor interactions in the Chukchi Sea. Results show climate-related stressors have a larger impact than acute stressors like shipping. Neglecting interactions significantly underestimates the risk of population crashes. The model highlights the need to account for stressor interactions in responsible management.
