8581Shining Light on Benthic Macroalgae: Mechanisms of Complementarity in Layered Macroalgal Assemblages“…Pioneering studies over 70 years ago showed how different pigmentation of red, green and brown algae affected absorption spectra, action spectra, and photosynthetic efficiency across the PAR (photosynthetically active radiation) spectrum. …”

8583“…Optimization of the production rate of biomass rich in N (e.g. for protein) or C (e.g. for biofuels) is key to making algae-based technology commercially viable. Creating the appropriate conditions to achieve this is a challenge; operational permutations are extensive, while geographical variations localise effective methods of cultivation when utilising natural illumination. …”

8585por Weston, Andrew J., Dunlap, Walter C., Beltran, Victor H., Starcevic, Antonio, Hranueli, Daslav, Ward, Malcolm, Long, Paul F.“…Instead, bleaching occurred by symbiont exocytosis and loss of light-harvesting pigments of algae that remain in hospite. These proteomic data are, therefore, consistent with our premise that coral endosymbionts can mediate their own retention or departure from the coral host, which may manifest as “symbiont shuffling” of Symbiodinium clades in response to environmental stress.…”
