Solos com influência ornitogênica na Ilha Greenwich, Antártica

Soils on Greenwich Island, Antarctica, show distinct chemical and mineralogical properties influenced by giant petrel activity, even though their guano input is less significant compared to penguins. The study found that soils currently under ornithogenic influence exhibit higher concentrations of phosphorus, nitrogen, and organic carbon, while those without recent bird activity contain elevated levels of calcium and magnesium. Researchers analyzed eight soil profiles and topsoil samples using physical, chemical, and mineralogical techniques, revealing that giant petrels modify soil properties sufficiently to contribute to the formation of weakly ornithogenic soils. This research highlights the nuanced impact of different seabird species on Antarctic ecosystems.
