Data from: Seabird presence and seasonality influence nutrient dynamics of atoll habitats

In this study, we investigate nutrient dynamics linked to seabird presence
and seasonality. We compare seabird colonies of different taxa nesting on
separate islands of Farquhar Atoll, Seychelles. We first quantify guano
nutrient input and guano nitrogen isotopes for each seabird species. We
assess the transfer of seabird-derived nutrients in terrestrial and marine
habitats by comparing nitrogen isotope values in soil, plants, and
seagrass on each seabird island and a control island, during the wet and
dry seasons. We then assess the influence of seabirds by comparing
nutrient levels in soil, plants, and seagrass on each seabird island and a
control island, during the wet and dry seasons. For plants and seagrass,
we also assess and compare nutrient ratios and carbon stable isotope
ratios on each seabird island and a control island, during the wet and dry
seasons.
