Kind: research · Impact: low

## In brief

- A Nature Climate Change study reports that for a tropical seabird model species, winter–spring phytoplankton blooms kept a stable mean timing but became more variable between years.
- The authors report that breeding synchrony in the seabird weakened as bloom timing became less predictable.
- The paper was published online on 13 November 2026 with doi 10.1038/s41558-026-02795-7.

## Why it matters

Reduced predictability of food availability, rather than only shifts in average timing, may disrupt reproduction in wild animals, which matters for conservation and for climate impact research.
