Description/Abstract

Reef-building corals host symbiotic algae known as zooxanthellae living within their tissues. Exposure to prolonged elevated temperature can cause corals to expel their symbionts and lead to coral bleaching. In this study, corals from Florida and Belize inshore reefs (high temperature variability) and offshore reefs (low temperature variability) were subjected to a 6-week-long heat stress experiment to determine if inshore corals displayed higher stress tolerance than offshore samples. Measurements of calcification rates suggested that Belize’s inshore or “BackReef” corals demonstrated the greatest growth and stress tolerance. Ongoing symbiont density measurements will provide further clues to stress tolerance.
