SUMMARY:Plenary Lecture 7: Mathematics of social behavior - Tarnita\, C (P
 rinceton University)
DTSTART:20141029T093000Z

CONTACT:Mustapha Amrani
DESCRIPTION:I will begin with a discussion and mathematical description of
  the two different types of social construction: `staying together' and `c
 oming together' (or aggregation). Staying together means that individuals 
 form larger units (complexes\, groups) by not separating after reproductio
 n (eg. ant colonies\, most multicellular organisms)\, while coming togethe
 r means that independent individuals form aggregates (eg. most animal grou
 ps\, including humans). For each of these operations I will discuss its st
 rengths and vulnerabilities in promoting social behavior\, which will lead
  naturally into a discussion of the various mechanisms (and the relationsh
 ips between them) that have been proposed to explain the evolution and mai
 ntenance of social behavior and cooperation: direct and indirect reciproci
 ty\, kin selection\, group/multilevel selection\, spatial structure\, puni
 shment/ostracism\, rewards. I will discuss the theoretical frameworks in w
 hich these mechanisms are generally studied and for each mechanism I will 
 present a simple model that captures the essence of how it can be describe
 d mathematically. Examples will be given from multicellularity\, eusociali
 ty\, bacterial biofilms\, animal and human behavior.\n
