When do smaller and when do bigger copopods peak in abundance and why? Name some small and some big copopods and how they spawn what is capital breeding?

Larger copopods peak earlier in the season f.eks. calanus species. Take advantage of spring bloom Smaller copopods grow later and are dominant in later part of summer. They are more affected by temp. Can feed from broader spectrum of organisms. Population is very much reduced over winter. Pseudocalanus (small) only make 100 egss * female^-1. Carry egg sack that protect from predation. Calanus > 1000. freespawning Acawtia 800-1000 eggs. Freespawning The two latter need a few generations for population to get big – later bloom. In arctic they use the saved lipids to reproduce – capital breeding – using resorts from last year is true for many arctic copopods. (psedocalanus)
