Each zooplankton species has its own set of life
history traits, influencedby its taxonomic lineage (e.g., gelatinous
zooplankton, copepods, euphausids), the physical characteristics of
the environment in which it resides and the suite of other species with
which it interacts. In seasonal environments, life histories may include
a dormant phase, which may occur at any life stage and vary in intensity
from almost complete shutdown of metabolism to merely arrested reproductive
activity. Losses from a population due to advection during dormancy
or active phases may prevent life cycle closure, for example in upwelling
zones, determining which species are dominant. Immigration from other
populations may be required to sustain species abundance within a particular
region. In this session we encourage presentations that together will
depict the variety of zooplankton life histories across all taxonomic
groups and how they interact with the physical environment at local,
regional or basin scales to determine species abundance and diversity
patterns.
