Ocean warming is increasingly affecting marine ecosystems across the globe. Reef-building corals are particularly affected by warming, with mass bleaching events increasing in frequency and leading to widespread coral mortality. Yet, some corals can resist or recover from bleaching better than others. Such variability in thermal resilience could be critical to reef persistence; however, the scientific community lacks standardized diagnostic approaches to rapidly and comparatively assess coral thermal vulnerability prior to bleaching events. We present the Coral Bleaching Automated Stress System (CBASS) as a low-cost, open-source, field-portable experimental system for rapid empirical assessment of coral thermal thresholds using standardized temperature …

Scleractinian corals are animal partners in exquisite symbioses with a suite of algal, microbial, fungal and viral associates comprising miniature ecosystems collectively referred to as a holobiont. In recent decades, ocean warming has jeopardized the delicate balance of the very symbioses that have enabled coral survival. Thermal stress causes a reduction of algal symbionts, a phenomenon referred to as ‘coral bleaching’ that represents dysbiosis in the holobiont and often leads to mortality. Current thermal acclimation theory states variation and gradual increases in temperature can ameliorate thermal stress. Indeed, there is evidence some coral species have some capacity to acclimatize to …
