Why AmP? Theory ↔ Applications (Jolyn’s talk) theory is tool in natural sciences in societal context impove tool by use AmP - - - - - = ecology/evolution = use in parameter estimation (estimation in context) ease applications DEB by examples database ready for applications checking consistency of data finding weird species identify patterns

Altriciality index animals birds mammals Birds stand out since they grow during a short period only, and get offspring long after reaching ultimate weight
Altriciality index The 2 altricity coefficients show little correlation, except for the tetrapods
Altriciality index The scatter of the absolute altriciality index increases with max struc length, that of the density altriciality index much less so
