Zero-variate data used for the estimation of the DEB model parameters.

1 birth is set at the moment the animal starts or is able to feed.2 moment at which the brachiolaria larvae is ready to settle for metamorphosis3 start of first gametogenesis4 maximum size reached by the species when there is no food limitation5 observations of maximum size at McMurdo field station6 maximum gonad index for an animal of the maximum size, gonad index as gonad weight/total wet weight.\]7 pyloric index for the food conditions in the laboratory as pyloric caeca weight/(total wet weight–gonad weight)All values are given at a temperature of 271.5 K. This is the temperature at which these values where measured. MRE: mean absolute relative error.
