Abstract:
Freshwater algae comprise a group of evolutionarily unrelated but ecologically allied organisms. Although unique in structure each algal lineage plays a role as a primary producer: fixing atmospheric carbon (and sometimes nitrogen) to biologically available forms in order to fuel aquatic food webs. Each algal species flourishes under particular conditions of light levels, water chemistry, nutrient availability and neighboring organisms. Understanding these environmental requirements of algal species can likewise reveal environmental conditions of aquatic ecosystems via bioassessment of algal communities.
