what factors are associated with conflict resolution?
Evolutionary stable strategy ( game theory and assumptions)
Evolution of display ( hawks and doves, hawks and doves and bourgeois)
what is strategy?
it is a behavioral response of an individual
what is ESS?
strategy which if adopted by all members of a population cannot be invaded by any alternative strategy . This is found using game theory
when is game theory needed?
it is needed when fitness consequences of a behaviour depend on what others are doing.( frequency dependent)
what is the example of a frequency dependence?
right and left jaw fish
what assumptions are made for ESS?
all strategies are specified
either pairwise contest occur or one individual competes against a group
possible behaviors associated with evolution of display?
fight but risk injury
what is pure ESS?
when they are all hawks or all doves. Usually when V resource is greater than cost
what does frequency dependence mean?
It means fitness depends on strategy frequancy
what is a mechanism for Mixed ESS?
stable strategy set in which a single individual sometimes performs one strategy and sometimes another with the probability p.
what does stable polymorphic state
in which a fraction p of the population adopts one strategy and the remainder 1-p adopts another.
what do side blotched lizards do ? what is this an example of ?
they have three throat color morphs
Blue they are ineffective against orange males
orange males have large territories
yellow males sneak copulation
this is an example of stable polymorphism
what is uncorrelated asymmetry?
it is where opponents differ but not with regard to fighting ability
example is the hawk dove and bourgeois
when is hawk dove bourgeois pure ESS?
if V> C then hawk will be pure ESS and when V
