Coral Disease and Management Insights

The video presents research on stony coral tissue loss disease in the US Virgin Islands, led by Madison Miller and the 2019 cohort. The disease, first reported in Miami in 2014, has spread to the Caribbean, affecting coral diversity. The research examines the disease's impact on coral species diversity, using a stratified random sampling design. Findings suggest that the disease does not follow the diversity-disease hypothesis, as it affects more diverse sites more severely. The cohort proposes management strategies, including prevention, detection, and restoration, to combat the disease's impact.

Where was the stony coral tissue loss disease first reported?
