Freshwater Algae of North America: Ecology and Classification (Aquatic Ecology)

Freshwater algae are one of the such a lot varied and ubiquitous organisms in the world. They occupy an immense variety of ecological stipulations from lakes and rivers to acidic peat swamps, inland saline lakes, snow and ice, damp soils, wetlands, wasteland soils, wastewater therapy vegetation, and are symbionts in and on many vegetation, fungi, and animals. In North the United States, the range of freshwater habitats colonized by way of algae is particularly wealthy, and provides an immense and engaging variety of environments for his or her research. They shape the bottom of so much aquatic nutrition webs and are severe to experiences of atmosphere overall healthiness. Algal ecologists and taxonomists play a major function within the figuring out of aquatic ecosystems: their biodiversity, productiveness, interactions with different organisms, and water caliber. This ebook presents in a single quantity a pragmatic and accomplished consultant to the genera of freshwater algae identified from North the USA. The structure combines the required ecological, taxonomic and methodological details for all scientists operating in aquatic environments, no matter if their strong point is in environmental tracking and water caliber overview, organic composition, ecology, evolution, or molecular biology.
