Abstract The maintenance of species and genetic
diversity within zooplankton egg banks may be crucial
to the re-establishment of zooplankton communities
following historical disturbance, such as anthropo-
genic acidification which globally caused widespread
damage to ecological communities. Despite this, no
other study has described basic characteristics of
zooplankton egg banks among lakes with different
acidification histories, such as variation in resting egg
concentration. Theoretically, habitats with frequent
periods of harsh environmental conditions are
expected to select for resting egg production or
prolonged dormancy in zooplankton, which would
