Impacts of marine heatwaves on top predator distributions are variable but predictable

H. Welch, M. S. Savoca, et al.

This exciting research reveals how marine heatwaves drastically affect the habitats and distributions of top predator species in the Northeast Pacific. Conducted by a collaboration of leading scientists, the study highlights the urgent need for dynamic ocean management tools to adapt to these rapid environmental changes.

Abstract
Marine heatwaves significantly impact marine ecosystems. This study models the effects of four Northeast Pacific heatwaves (2014, 2015, 2019, 2020) on 14 top predator species. Predicted responses varied widely, from near-total habitat loss to doubling. Heatwaves rapidly shifted predator distributions across political boundaries. A dynamic ocean management tool predicting predator distributions in near real-time is presented.
