The circular seabird economy is critical for oceans, islands and people
Nearly a third of seabird species are at risk of extinction, rendering them among the most threatened bird taxa globally. The decline in seabird populations has major ramifications for their associated ecosystems. An expansive literature covers seabird impacts on their breeding islands, and growing research expands understanding of the circular seabird economy — cross-ecosystem connections of seabirds from oceans to islands, and back to nearshore marine ecosystems, mainly driven by nutrient transfer.
