- •
Cormorants transport nutrients from water to land ecosystems and pollute biogenically.
- •
We studied stable isotope composition of small mammal hair in 3 cormorant colonies.
- •
δ13C and δ15N were measured using elemental analyzer–isotope ratio mass spectrometer.
- •
δ13C and δ15N values were higher in rodents inhabiting cormorant colonies.
- •
Disruption of the ecosystem caused by Great Cormorant colonies affects small mammals.
