**Water displacement volume (mL) conversion to dry weight: multiply by 0.11. Ash-free dry weight conversion to dry weight: multiply by 1.33. Fresh weight conversion to dry weight: multiply by 0.15.
***Codes: 1 = Excess turbidity or color; 2 = Competition by angiosperms; 3 = Competition by macroalgae or phytoplankton; 4 = Excess wave action; 5 = Excess water depth; 6 = High water temperatures; 7 = Excess water salinity; 8 = Excessively coarse sediments; 9 = Water level fluctuations; 10 = Excess sediment salinity; 11 = Excessive comsumption by birds; 12 = Excess water currents; 13 = Epiphytes; 14 = Insufficient water column nutrients; 15 = Excessively soft sediments; 16 = Insufficient insolation.
