Effects of climate variability on Calanus dormancy patterns and population dynamics in the Northwest Atlantic
J.A. Runge, A. Leising, C. Johnson

Lipid accumulation window hypothesis
Individual Calanus can only enter diapause if their food and temperature history allows them to accumulate sufficient lipid for overwintering and gonad development
Decision to proceed to dormancy is initiated when lipid stores reach a preset threshold (% by weight in stage CIV)
Exit from dormancy by endogenous timer or when lipid stores decrease below a preset threshold
