1) Based on what you have learned so far about the typical limiting nutrient in freshwater ecosystems (and, yes, Lake Okeechobee is freshwater), what nutrient would you generally expect to be the most likely limiting resource for Lake Okeechobee?

2) How do Crosby and Havens each describe the role of nutrient contamination, particularly phosphorus and nitrogen, in initiating freshwater cyanobacteria (aka, blue-green algae blooms) blooms in Lake Okeechobee? What other factors do either of these researchers cite as a potential “trigger” for the cyanobacteria blooms to form in Lake Okeechobee?

3) Based on your reading of both Crosby and Havens (as well as any materials from lecture or other sources), describe why and how severe freshwater cyanobacteria blooms frequently occur in normally brackish ecosystems like the St. Lucie River estuary (on the east coast) and Caloosahatchee River estuary (on the west coast). (Hint – freshwater cyanobacteria normally would not survive in a saltwater estuary environment.)
