Question 4

## 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 Variables | Physical Variables
--- | ---
Predation vulnerability | Temperature
Resource availability | Horizontal advection, including squirts, jets
Genetics | Catastrophic events (e.g., volcanoes)
Parasites | Turbulence
Catastrophic episodes of predation (e.g., fish schools) | Vertical distribution of variables at various time scales
Biochemical composition abundance and size distribution of food particles | Meteorological events over days to years
Competition from other zooplankton (e.g., Thaliacea affect copepods) |
