Abstract

Globally, climate change-driven marine heatwaves are causing increased coral bleaching and mortality events with cascading effects, including reef habitat complexity. Given that habitat complexity positively influences biodiversity and organismal abundance, such losses have negative ramifications for these ecosystems. Past studies have documented habitat complexity changes following heatwaves, yet…
