Fission

Splitting

Fusion

Merging

what is temporal variation

changing membership

Why is changing membership important

social activity, idv. group choice decisions, higher connectivity over time, between group interchange

Factors of a No FF group

Fully stable group

No splitting/merging

No interchange

strong community structure

factors of max FF

Fulling mixing groups

Max splitting/merging

Maximum connectivity

Minimum community structure

Example of no FF and max FF

Primates and birds (respectiveley)

Focal Follows

Specific question - follow an animal for 20 min and record all social interactions

What do short term study systems focus on

varried methods to target a specific question or study

What do long-term study systems focus on

Consistant methods with a broad scope of research

gennerally consisting of indv marking, across generations, the entire population

What is gambit of the group for

Controlls observations, spatio-temporal effects, data structure then calculates

Can we quantify FF in a comparative way

Yes, think about the No FF to Max FF range

How does cognition and behavior shape fission fusion

Systems with the lower cognition we see the most FF

What are the consequences of FF for contagions

How fast a contagion can travel through the group
