Zooplankton was sampled in the coastal and in the pelagic zone (c. 2.5 km offshore).
In weak ones, anchoveta and zooplankton both consume phytoplankton and are in turn ingested by carnivores.
Crustacean zooplankton food web structure in lakes of varying acidity.
Cladocerans amounted to maximum 5% of the zooplankton numbers, and rotifers were always at relative abundances lower than 1%, possibly due to inadequate mesh size to sample all rotifer species.
We were unable to count particles on the 250 and 125 m sieves owing to the abundance of zooplankton faecal pellets that obscured the charcoal.
They were part of a complex trophic web of the time including primary producers (phytoplankton) and primary to tertiary consumers (zooplankton and filterfeeders, suspension and deposit feeders, and invertebrate predators).
In addition, mysids can migrate into the zooplankton.
It is not immediately clear why this should be so, but it may relate to abundance of zooplankton.
