Subtropical seagrass epiphytes: Nitrogen fixation rates align with Crocosphaera‐like cyanobacteria abundances

open access: yesLimnology and Oceanography, EarlyView.
Abstract Nitrogen fixers can enhance nitrogen availability for seagrass communities that may be nitrogen limited. However, the role of epiphytic diazotrophs, particularly cyanobacteria, in seagrass communities is not well understood. We measured nitrogen fixation rates, epiphyte biomass, and relative abundances of epiphytic diazotrophs on the leaves of
