Term | Definition |
natural process in the evolution of lakes in which low nutrient, clear, deep water lakes with little vegetation slowly succeed to become converted to high nutrient, green, shallow lakes with abundant benthic vegetation. | Eutrophication |
Eutropication is caused by adding ___ to salt water, and ____ to freshwater | Nitrogen, Phosphorous |
Types of HAB's is a species that produce toxins and the effects are | harmful to wildlife; linked to fish and mammal death |
Types of HAB's: non-toxic species that attain a high biomass | destroy fish and shellfish habitat because of O2 depletion leading to hypoxia and anoxia |
neurological symptoms, often fatal | Paralytic shellfish poisoning (PSP) |
including inhalation of toxins as aerosols-- milder from of PSP-not fatal | Neurotoxic shellfish poisoning (NSP) |
can be fatal-GI and neurological symptoms--permanent CNS damage possible | Amnesic Shellfish Poisoning (ASP) |
no neurological symptons—gastrointestinal symptoms disturbance | Diarrhoetic shellfish poisoning (DSP) |
gastrointestinal, neurologic, and cadiovascular symptoms-paralysis and death possible | Ciquatera fish poisoning (CFP) |
Produces domoic acid which is biomagnified by food chain leading to sickness and death of sea lions and other marine mammals on U.S. west coast. Also, results in amnesiac shellfish poisoning (ASP) in humans | A toxic diatom |
The relative concentrations of various inorganic nutrients (and organic compounds) for phytoplankton species | Nutrient Ratio Hypothesis |
List some tools for monitoring HAB's | molecular probes, citizen monitoring, modeling |
