SBC LTER: Reef: Macrolgal photosynthetic parameters and biomass relationships

These data tables contain the relationships used to estimate biomass
density from field measurements of abundance, and laboratory-derived values for
photosynthetic parameters (Pmax, alpha, and dark respiration) for 19 taxa of understory
macroalgae. Collectively, these taxa comprised 97% of the total understory macroalgal
biomass at the SBC LTER long-term kelp removal experiment sites during 2008-2011.
Biomass density is derived from either a linear relationship (adults) or average
per capita biomass (juveniles). Relationships and photosynthetic parameters can be
combined with field
data on algal abundance and irradiance to estimate net primary production for the understory
assemblage community. These data were presented in: Harrer, S.L., D. C. Reed, R. J. Miller and S. J. Holbrook. 2013.
