Discussion
- Mod_1: In view of low somatic maintenance, pseudodata k_J = 0.002 1/d is replaced by pseudodata k = 0.75
- Mod_2: data from the Ningaloo population are calculated for f=0.8 based on the ratio of the size attained by the Ningaloo population and the size of the largest published green turtle record
- Mod_2: we assume that the density of yolk is different than that of the density of reserve and structure. So the yolk density d_Y is introduced as an extra parameter.
- These parameter values and model predictions are presented and discussed in the paper: Stubbs et al, "A full life cycle Dynamic Energy Budget (DEB) model for the green sea turtle (Chelonia mydas) fitted to data on embryonic development"submitted to the Journal of Sea Research, DEB special issue 2018
- Mod_3: Mod_3: 3-parameter Arrhenius function describing upper boundary for thermal tolerance has been added to capture the slower rate of change of development rate at high temperatures more accurately. Additionally, pseudodata point k has been modified to k=0.75 to be more in line with other sea turtle models in the collection. See StubMitc2018 for a full discussion of this entry.
