Note(s): In Hawaii, blooms of native and non-native macroalgae (limu) have become increasingly problematic in recent decades. Although the role of human vectors in introducing non-native macroalgae is well documented, the ecological role of nutrient pollution in facilitating blooms of these species is not. This study assessed the effects of stormwater discharges on the diversity, abundance, and nutrient content (C, N, P and δ15N) of native and non-native limu at three sites in the intertidal zone at Ewa Beach, O’ahu. The results showed that native limu species diversity and abundance decreased with proximity to a stormwater outfall (ASWO), whereas non-native species abundance increased. Limu tissue δ15N values at all three sites were within the range reported for sewage N. δ15N, %N, and N:P ratios all increased with proximity to the ASWO, supporting the hypothesis that stormwater was a primary source of N enrichment in the study area.
