The worldwide decline of coral reefs has renewed interest in coral communities at the edge of environmental limits because they have the potential to serve as resilience hotspots and climate change refugia. These coral communities are commonly referred to as marginal or extreme reefs, with many perceived to be the “poor cousins” of ''normal'' reefs. Yet many of these reefs are characterised by high coral cover, biodiversity and ecosystem functioning, and may therefore, provide critical insights into how coral reefs might function under suboptimal environmental conditions, including future climate scenarios. Despite the potential management and conservation value of marginal and extreme reefs, they remain comparatively understudied. This theme aims to bring together researchers in the Asia-Pacific region working on marginal and/or extreme reefs (e.g. high latitude reefs, turbid and mesophotic reefs, urban reefs, mangrove lagoons, upwelling influenced reefs, high-temperature reefs, high CO2 seep reefs, macrotidal reefs) in an effort to highlight new research and form new collaborations that exchange data and knowledge, and identify important knowledge gaps. In doing so, improve our understanding of these potentially critical reef systems, and the role that they could play in facilitating future coral reef survival.
