[ #Seabirds influence vegetation ]
👩🔬 Isotopes & nutrients were compared at an active, abandoned, and control shearwater site
📈 Vegetation & herbivores showed δ¹⁵N enrichment from guano, but soil δ¹⁵N remained unchanged
🏝️Phosphorus and potassium concentraitons suggest that seabirds fertilize soils

⭐#NewPaper alert⭐ Dr Megan Grant's last chapter of her #AdriftLab #PhD thesis focuses on the key role #seabirds play in transporting nutrients from the ocean to their breeding sites (in this case, #LordHoweIsland)

Many seabird populations are decline, this means fewer marine-derived nutrients are being deposited on islands. On Lord Howe Island, soil collected from active shearwater colonies contained elevated ....
