TL;DR: Populations of the imperiled reef‐building coral, Acropora palmata, have experienced little or no recent genetic exchange between the western and the eastern Caribbean, and should have the potential to adapt to local conditions and will require population‐specific management strategies.

TL;DR: The necessity for consideration of alternative (e.g., hybrid) ecosystem states is highlighted, traits of resilient corals and coral reef ecosystems are discussed, and a decision tree for incorporating assisted evolution into restoration initiatives to enhance climate resilience of coral reefs is proposed.

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.

TL;DR: Fertilization, settlement, and growth were all negatively impacted by increasing pCO2, and impairment of fertilization was exacerbated at lower sperm concentrations, suggesting that OA has the potential to impact multiple, sequential early life history stages, thereby severely compromising sexual recruitment and the ability of coral reefs to recover from disturbance.

TL;DR: It is argued that sexual recruitment is more prevalent in the eastern range of A. palmata than the west, and that these geographic differences in the contribution of reproductive modes to population structure may be related to habitat characteristics.
