Extreme weather events reduced breeding success for seals, albatross, and shearwaters in Tasmania

The study tracked reproductive outcomes across multiple breeding seasons and linked lower success rates to storms, heat waves, and other severe conditions. Researchers documented fewer surviving offspring during years when extreme weather occurred during critical nesting and pupping periods.

methods The analysis covered coastal and island breeding sites used by the three species. Data collection included counts of eggs, chicks, and pups alongside weather records for the same locations. The findings show consistent patterns across the different species despite their distinct life histories and habitat needs.

Changes in breeding success can affect population numbers over time. Further monitoring will track whether the observed reductions continue in future seasons.
