Lipid Accumulation Window hypothesis:
Step 1 - Conditions allowing dormancy: suppose only copepods with > 50% lipid content can enter

At warmer temperature (or higher cumulative T) the copepods develop proportionally faster than they grow, thus they are unable to accumulate as high a % of lipids.
The % of ingested food that can be accumulated increases as the concentration of food increases (Hakanson 1984 L+O).
