The occurrence of cyanobacterial harmful algal blooms (cyanoHABs) is related to their physical and chemical environment. However, less is known about their associated microbial interactions and processes. In this study, cyanoHABs were analyzed as a microbial ecosystem, using 1 year of 16S rRNA sequencing and 70 metagenomes collected during the...

Advancing the understanding of Cyano-HABs in New York State
Tony Prestgiacomo, Jennifer L. Graham, Guy M. Foster
2024, Report
Most harmful algal blooms (HABs) in freshwater lakes, rivers, and streams are caused by cyanobacteria (Cyano-HABs). Under certain environmental conditions, dense concentrations (blooms) can form, which have the potential to cause aesthetic, ecological, and economic damage to afflicted waterbodies. Most importantly, Cyano-HABs can cause physical harm to people, pets, and...
