    Sea-level rise threatens coastal mangroves, with global consequences for these important blue carbon sinks. Here the authors analyse four Holocene sediment cores from islands in Florida Bay and find that mangroves that comprised the South Florida coastline 4–3000 years ago rapidly transitioned to estuarine conditions, despite low rates of sea-level rise, and propose that their demise was driven by high climate variability.

    Animal diversity, measured in numbers of species, is rapidly being lost to extinction. Here, Cooke et al. show that the diversity of ecological strategies employed by land mammals and birds is also expected to narrow towards small, fecund, insect-eating generalists with fast-paced life histories.
