Physiology, ecology, and toxic properties of marine cyanobacteria blooms
Cyanobacteria blooms in marine waters are limited to only a few taxa with Trichodesmium, Richelia, Nodularia, and Aphanizomenon being most commonly observed. Nonheterocystous, nitrogen‐fixing Trichodesmium spp. are found throughout low and mid‐latitude oceans and seas of the Atlantic, Pacific, and I...
