Algae are the most abundant photosynthetic organisms in marine and freshwater ecosystems and are essential, energy-producing components of aquatic food webs. Harmful algal bloom or "HAB" species are a small subset of algal species that produce toxins and/or bloom to excess, thus creating harm to humans and ecosystems. Humans, domestic animals, and wildlife, including endangered species, can be exposed to algal toxins through their food, drinking water, the water in which they swim, or aerosols. It is widely believed that the frequency and geographic distribution of HABs have been increasing worldwide. All U.S. coastal states have experienced HABs over the last decade, and new species have emerged in some locations that were not previously known to cause problems. The authors of this book analyze and discuss the most recent research done in this field.This book consists of public documents which have been located, gathered, combined, reformatted, and enhanced with a subject index, selectively edited and bound to provide easy access.
