Abstract
- We tested the sensitivity of coastal picophytoplankton exposed to natural sunlight in short-term experiments. Cell abundance and cell-specific chlorophyll fluorescence were significantly reduced in Prochlorococcus spp. but not in Synechococcus, whereas picoeukaryotes had an intermediate response. These results are the first direct evidence of a differential sensitivity to sunlight of these ubiquitous marine members of unicellular phytoplankton.
