The annual cycle of phytoplankton biomass was followed in a eutrophic lake (Lake Aydat,
Massif Central, France), using classic descriptors (biovolumes and chlorophyll a) as well as
adenosine-5′-phosphate (ATP) levels. ATP is the metabolite indicating living biomass.
ATP/Cell count and ATP/Chlorophyll a ratios were elevated due to the presence of
heterotrophic organisms, such as several species of ciliates. The first ratio is greater than the
second. The difference can be explained either by an underestimation of the nanoplankton …
