Animal personalities Flashcards
whats inter plasticity?
individual vars between individuals
whats intra plasticity?
variation within an individual
whats optimality?
model of what the optimal response would be
examples of inter var?
diet space and habitat use
what can be assumed about individual var and the population var?
that between individual var can comprise the majority of a populations var
what is phenotypic plasticity?
ability of an organisms to produce different phenotype depending on the environmental conditions
what are reaction norms?
graphical representation of how a phenotype varies across an environment
what does selection require ?
variation within a population
what is heritability ?
phenotypic var that is dependant on genomic variation
what the slope in reaction norms ?
individual reaction norms
what the elevation in reaction norms?
average trait value
what is personality?
consistant individual behavioural differences over time/and or / contexts (life history phases)
whats behavioural syndrome?
correlations eg bigger might be more aggressive
what are the 4 theories as to why personality is maintained within a population?
externally induced differences in states
freq dependant selection
spatio/temporal var in environment
non equilibrium dynamics
whats external induced diff in state?
idea that animals states can influence behaviours, random life events in early life ie ticks infections over pop can cause diff behaviours
whats freq dependant selection?
each behavioural type has equal mean fitness , depends on distribution in pop
too many stealers wouldn’t work
whats genetic polymorphism?
have pure strategies they follow
whats genetic monomorphism?
single genotype with mixed strategies
whats addaptive co existance ?
fitness depends on the surroundings
diff selection pressures would favour diff behaviour
depends on orgs having a lack of plasticity
whats non equilibrium dynamics?
ongoing oscillations/ flux in selection pressures
what is critical anthropomorphism ?
when we are limited in understanding through being human
whats the law of parsimony?
anything we observe should be explained by the simplest explanation
