The IUCN Red List of Threatened Species: an assessment of coral reef fishes in the US Pacific Islands
Brian J. Zgliczynski,Ivor D. Williams,Robert E. Schroeder,Marc O. Nadon,Benjamin L. Richards,Stuart A. Sandin +5 more
TL;DR: The findings complement IUCN assessment efforts, emphasize the efficacy of large-scale assessment and monitoring efforts in providing quantitative data on reef fish assemblages, and highlight the importance of protecting populations at remote and uninhabited islands where some species included on the I UCN Red List of Threatened Species can be observed in abundance.

TL;DR: This paper identified 15 bright spots and 35 dark spots among more than 2,500 reefs worldwide and developed a Bayesian hierarchical model to generate expectations of how standing stocks of reef fish biomass are related to 18 socioeconomic drivers and environmental conditions.

TL;DR: A global survey of reef fishes shows that the consequences of biodiversity loss are greater than previously anticipated as ecosystem functioning remained unsaturated with the addition of new species.
Journal ArticleDOI
Large-scale associations between macroalgal cover and grazer biomass on mid-depth reefs in the Caribbean
TL;DR: The abundance of macroalgae on lightly fished reefs may be a symptom of low coral cover in combination with the continuing absence of Diadema antillarum, a contributory factor in overfishing of grazing fishes.

TL;DR: Overall reef fish density has been declining significantly for more than a decade, at rates that are consistent across all subregions of the Caribbean basin and in three of six trophic groups, indicating that Caribbean fishes have begun to respond negatively to habitat degradation.
