Declining environmental predictability erodes reproduction in a tropical seabird
Nature Climate Change, Published online: 13 November 2026; doi:10.1038/s41558-026-02795-7 The authors show that, for a tropical seabird model species, winter–spring phytoplankton blooms kept a stable mean timing but became more variable between years. Breeding synchrony weakened and reproductive success declined and became less consistent over the same two decades.
