Selection of mesophotic habitats by Oculina patagonica in the Eastern Mediterranean Sea following global warming

Abstract Globally, species are migrating in an attempt to track optimal isotherms as climate change increasingly warms existing habitats. Stony corals are severely threatened by anthropogenic warming, which has resulted in repeated mass bleaching and mortality events. Since corals are sessile as adu...
