Underwater Light Manipulation by the Benthic Diatom <i>Ctenophora pulchella</i>: From PAR Efficient Collection to UVR Screening

Several species of diatoms, unicellular microalgae which constitute the main component of phytoplankton, are characterized by an impressive photosynthetic efficiency while presenting a noticeable tolerance versus exposure to detrimental UV radiation (UVR). In particular, the growth rate of the araph...
