Cover image: Pictured is a juvenile giant grouper (Epinephelus lanceolatus), categorized as vulnerable by the International Union for the Conservation of Nature. David Mouillot et al. investigated the species diversity and functional diversity of fish faunas inhabiting coral reefs around the world. Despite high species richness, the authors found that more than 40% of functional entities are served by a single fish species, such as the giant grouper, making functional diversity highly vulnerable to single species loss. See the article by Mouillot et al. on pages 13757–13762, part of the Functional Biogeography Special Feature.
