  2. DEB3 statistics Energy & metab. Multivariate DEB Effects of comp. Univariate DEB Basic concepts Living together Standard DEB Co-variation Extensions Short title Evaluation Evolution

  3. 30 new features in DEB3 • Improved text organisation/presentation • New set of primary parameters • Maturity as fundamental state variable • Emphasis on homeostasis, incl evolution • Mechanism reserve dynamics/merging • New chapter on evolution • Parameter estimation in steps • Isotope dynamics • Thermodynamic aspects extended • Aging extended (includes demand syst.) • New patterns in par-values/QSARs,temp • SU theory extended: shrinking, adaptation, social interaction, co-metab • Static/dynamic generalisation κ-rule • Trajectory reconstruction (reprod/otolith) • Separation of cells in early embryos • Handshaking in chains of SUs • Organnelle-cytosol interactions • Metamorphosis • Reproduction-buffer handling rules • Isomorphs as V0-morphs • Flocculated growth • Otolith growth • Pseudo-faeces production • Photo-inhibition • Mother-foetus interactions • Changes in composition during starving • Extra-cellular digestion • Hormesis • Film models • Effects of mixtures extended (NECs)

  4. Hazard rate  Survival Prob

  5. Aging in DEB3

  6. Aging in DEB3

  7. Aging: non-growing ectotherms survival prob Data: Rose 1984 Weibull with shape parameter 3 time, d

  8. Aging: growing ectotherms survival prob body weight, g time, d time, d Weibull with shape 3 fits ectothermic survival well, even if growth period not small relative to life span Data: Slob & Janse 1988

  9. Aging: relation to O2-use survival prob Reodruction rate, #/d 0.374 high food 10/20°C high food 10/10°C low food 10/20°C 0.547 0.630 time, d time, d Differences in life span are caused by differences in respiration Data: Ernsting & Isaaks 1997

  10. Aging: sex differentiation survival prob body weight, g time, d time, d Differences in aging between sexes are caused by differences in g Data: MacArthur & Baillie 1929

  11. Aging: endotherms & feeding feeding level 1 body weight, g embryo weight, g 0.75 0.44 time, d time, d 0.44 survival prob • Life span • hardly depends on food in ecotherms • decreases for increasing food in endotherms 0.75 1 time, d Data: Weindruch et al 1986 MacDowell et al 1927

  12. Aging among species Right whale slope 1/3, 1/5 Ricklefs & Finch 1995 • Conclusion for life span • hardly depends on max body size of ectotherms • increases with length in endotherms
