Fig. 14.6 Seasonal
variations of viral
abundance (Virus-Like-
Particles, VLPs) in the
epilimnion,
metalimnion, and
hypolimnion of Lake
Pavin ( A ). Relationship
between bacterial and
viral abundances in the
oligomesotrophic Lake
Pavin compared to the
eutrophic Lake Aydat
( B ). Variation in the
average ratio of
viral-induced mortality
to heterotrophic
nanofl agellate grazing-
induced mortality of
prokaryotes in Lake
Pavin, compared to 10
other lakes ( C ) of the
same geographical
region (the French
Massif- Central, refer to
Pradeep Ram et al. 2013
for more details on these
lakes)
