The Arctic is no longer pristine. “Forever chemicals” like OPEs and PFAS are accumulating in wildlife and ecosystems, threatening Inuit food sources. By studying Arctic seabirds as early-warning indicators, this research provides critical evidence to inform regulation and protect vulnerable environments and communities.

Feathers and blood preserve detailed biological records of Tītī stress, diet, and environment across both New Zealand and the North Pacific. By analysing hormones and stable isotopes in modern and historical samples, this research reveals how climate change affects Tītī populations and identifies which groups are most vulnerable, guiding future conservation efforts.
