Deposits of seabird guano on marine shores have drawn the attention of companies and naturalists for centuries. Among notable effects, allochthonous energy/matter inputs by seabirds are responsible for shifts in ecosystem functioning next to colonies. Here, we used stable isotopes of nitrogen-15 (ra...
