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) |
