What is communication
between animals?
Communicative signals carry information
about
Communication is the transmission and
reception of signals between animat
Food (eg. food vectors)
Danger (eg alarm calls)
A signal is a stimulus transmited hom one
organism to another
The communicator's traits (eg. readiness to
mate, value for a mate, readiness to fight)
What is a signal?
What kinds of information do
animals communicate?
Communicative signals are exchanges
between
In some eusocial insect
species, indivkdals
transfer information about
food vectors to other
members of the colony
Conspecifics (sooal group members. potential
mates parents- offspring)

1) In the following scenarios determine if the communication scenario is deceit, mutuality, eavesdropping or spite. Be sure to justify your answer.
a) Male guppies have red spots to attract mates. The redness comes from the diet of the male. Females prefer redder males when choosing a mate.
b) In some species of frogs, smaller males will cue in on a larger male’s calls and try to intercept females before they reach the calling male.
c) In some colonies of Argentine ants, workers will kill off males in order to bias the sex ratio so there are more females within the colony.
d) The parasitoid wasp Pachysomoides fulvis will absorb the colony smell and will be able to move freely on the nest of the social wasp Polistes and lay its eggs in the cells of the host wasp’s nest..

- An experiment with squirrels revealed that they make alarm sounds when a model of an owl is placed near them. When a red cube, about the same size as an owl is placed there, there seems to be no alarm. Which of the following best explains this reaction? The owl model is the ultimate cause of alarm vocalization behavior. The owl model, but not the red cube, triggers the fixed action pattern of alarm vocalizations. The squirrel is trying to attract the owl into its territory. The squirrels cannot see red objects, and so do not make alarm sounds. 0000arrow_forwardWhat are some behaviors that help animals avoid predation?arrow_forwardFemale parasitoid wasps search for insect hosts in which to lay eggs, and they can often discriminate among individual hosts that are more or less suitable for their offspring. Behavioral ecologists have asked whether or not the wasps’ willingness to lay eggs in less suitable hosts varies with the female’s age.
