Summer Undergraduate Research in Biology Program
Macroalgae form important coastal ecosystems and are considered to be highly
productive, yet individual macrophyte carbon uptake rates are
poorly documented and methodologies for in situ assessments of productivity
are not well developed. In this study, we employ a 13C enrichment method in
benthic chambers to calculate carbon uptake rates and assess d13C signatures of
a large stock of nearshore benthic macroalgae varying in taxa and morphology in
Southern California. Our objectives are to 1) identify the variability of carbon
uptake and inorganic carbon use among individuals of the same species or
morphology and speculate how macroalgae might respond to …
