**About the Editors**

**Rupert Ormond** now lives on the Isle of Mull in Scotland and is currently affiliated with Heriot-Watt University in Edinburgh, having previously worked at the Universities of Cambridge, York, London, and Glasgow, as well as for two conservation organisations—the Save Our Seas Foundation and Marine Conservation International. He has been involved in research and conservation on coral reefs for over 50 years, mainly in the Red Sea and Indian Ocean regions. His research has focused on reef fish communities, ecological interactions between reef organisms, impacts affecting corals and the behaviour of sharks. At the same time, he has played a key role in the establishment and management of Marine Protected Areas and National Parks in a series of coral reef countries. He was Corresponding Secretary of the International Coral Reef Society from 2011 to 2019 and is now Editor-in-Chief of the Society's bulletin *Reef Encounter*.

**Peter Schupp** is head of the Environmental Biochemistry group at the Institute of Chemistry and Biology of the Marine Environment and a founding member of the Helmholtz Institute for Functional Marine Biodiversity, both at the University of Oldenburg, Germany. Previously he has been working as faculty and director at the University of Guam Marine Laboratory, Guam, USA. He has over 30 years of experience in benthic coral reef ecology, mainly on Indo-Pacific coral reefs. His research focuses on the chemical and microbial ecology of marine invertebrates, often using sponges as model organisms to study the microbe-host associations. Another research emphasis is the identification and function of chemical signals from crustose coralline algae and associated biofilms during coral settlement. Recently, research also involves investigations on coral reef benthic community changes, especially the identification of possible drivers towards communities dominated by organisms other than hard corals.
