what is communication
the transfer of infomation from one or a group of animals that affects the current or future behaviour of one or more animals
what is true communication
natural selection acted on the sender and the receiver
what is infraspecific communication
infomation that is communicated between animals of the same species
what is interspecific communication
information that is communicated across animals of different species
what are the 4 main types of communication
visual, auditory, tactile and chemical
what are the 3 additional forms of communication
mutualism
deceit
manupiualtion - eavesdropping
what is mutualism
both species benefit from the communication
honey badger and guide birds - bird guide and badger opens hive for both
deceit - mimicry
debit occurs when signallers fitness increases at the expense of the receiver
manipulation - eavesdropping
occurs when the receiver obtains infomation about the signaller, against the signaller interest
why bro we study communication
helps scientists to study:
social hierarchies
agression and courtship displayes
bonding and parental care
predator prey interactions
cognitive studies and learning
emotions
examples of tactile communicaton
monkeys (macaque) grooming each other
examples of auditory communication
wolf howling
examples of chemical communication
skunk spray
examples of visual communication
peacock showing feathers
what is social behaviour
a variety of interactions that occur between 2 or more animals
types of social behaviour
hierarchies
maintaining dominie relatinships
agnostic behaviour
social bonding and affiliative behaviour
alturism
hierarchies
linear
triangular
despotic
coalition
what is hierarchy
pecking order - animals at top dominate those below
linear hierarchies
animal a dominates animal b
animal b dominates c
example chickens
triangular complex hierarchies
animal a dominates animal b
animal b dominates animal c
animal c dominates animal d
animal d then dominates animal b
complex - order of the group can change depending on hunting and mating
example wolves
true complex hierarchies
seen in groups of animals that contain many members
difficult to record as individual may not interact with eahcother
several triangular relationships may exist
example ants
maintaining dominance
facial expressions
body postures
vocalisations
physical features and contact
