Definition Taxanomic Phylum Species binomial or genus The method used for measuring abundance; also the independent variable in the linear regression used to estimate biomass density (as g dry mass m-2) Slope of the relationship between abundance (various units) and biomass density (gram/meter2). Slope unit varies depending on abundance measurement method. The coefficient of determination for the linear regression between measurements of abundance and biomass density Sample size of measurements in the slope calculation Mass-specific production rate at saturating irradiance ((mg C hr-1) (g dry mass) -1) Pmax standard error (mg C hr-1) (g dry mass) -1) Mass specific production rate at non-saturating irradiance (mg C hr-1) (g dry mass) -1) / (µmol photons m-2 sec-1) Standard error in units of (mg C hr-1) (g dry mass) -1) / (µmol photons m-2 sec-1) for Mass specific production rate at non-saturating irradiance. Mass specific respiration rate in the dark in units of (mg C hr-1) (g dry mass) -1) Standard error in units of (mg C hr-1) (g dry mass) -1) for mass specific respiration rate in the dark. Sample size of individuals measured for Pmax, α and respiration estimates.
