New research shows invertebrates can be harmed by cyanobacteria
Algal blooms are becoming more and more frequent. Those blooms can be harmful for freshwater lakes and nearby ecosystems and communities. One of the dominant algae species in those blooms is a cyanobacteria named Microcystis. Cyanobacteria are also called blue-green algae and are so tiny, that you can only really see them under the microscope. Despite their size, they can have detrimental effects on organism and can cause death to humans, dogs, fish, birds, etc. Those negative effects are the result of a toxic substance belonging to the class of microcystins.
