Extreme Weather Reduced Breeding Success for Seals and Seabirds in Tasmania

The study tracked multiple breeding seasons and recorded lower survival rates for pups and chicks during periods of severe weather. Researchers linked the declines to storms, heat waves, and heavy rainfall that disrupted nesting sites and increased mortality.

Data came from long-term monitoring programs that counted breeding pairs and offspring survival each season. The analysis compared years with and without extreme weather to isolate the effect of those events.

Fur seals experienced reduced pup survival when storms flooded breeding beaches. Albatross and shearwater colonies showed lower chick survival during heat waves and heavy rain that damaged nests. The findings add to existing records of how weather variability affects marine and coastal wildlife populations.
