Question 4. Which are the variables causing most of the recruitment variability?

Question 4 Response--As to variables causing variability of recruitment, there was good agreement among the workshop participants. These responses are summarized in the table given below.

Biological VariablesPhysical Variables
Predation vulnerabilityTemperature
Resource availabilityHorizontal advection, including squirts, jets
GeneticsCatastrophic events (e.g., volcanoes)
Catastrophic episodes of predation (e.g., fish schools)Vertical distribution of variables at various time scales
Biochemical composition abundance and size distribution of food particlesMeteorological events over days to years
Competition from other zooplankton (e.g., Thaliacea affect copepods)
