Assessing the potential of fluorescence as a monitoring tool for reproductive tissue in selected macroalgae species
Biofluorescence in certain seaweed species has been studied in association with their respective chlorophyll type and concentration. However, there is a paucity of information on the biofluorescent signature of macroalgal species at different life stages. Here we document that hyperspectral imaging...
