Study quantifies extreme weather impacts on marine predator breeding in Tasmanian climate hotspot
By
Mary-Anne Lea
Summary
This scientific study examines how extreme weather events (EWEs) impact the breeding success of marine predators in Tasmania, Australia—a global climate change hotspot. Using long-term datasets across 14 colonies of three sentinel species (including Australian fur seals), the research quantifies how increasing intensity and frequency of extreme weather leads to breeding failures in these long-lived, slow-reproducing species. The study identifies specific temporal windows of vulnerability during breeding seasons and links EWE-driven failures to population-level consequences.

· 3 pulledExtreme weather events (EWEs) are increasing in both intensity and frequency globally.
For long-lived, slow-reproducing marine predators, repeated or sequential EWE-driven breeding failures can have population-level consequences.
We quantified effects of EWEs on reproductive output and identified temporal windows of vulnerability during breeding in three sentinel species across 14 colonies with varying population trajectories in Tasmania, Australia.
