Do I FLEE from it? Do I FIGHT with it? Do I FEED on it? Do I F*CK it? Mammas live by these four F's
Behavioral patterns that convey messages between animals
Describe the sender's state
Actual physucal form of the message; smell, physical touch, sound, etc
Behavior of one org influences the behavior of another org.
Control recipient's behavior with little effort.
Very rare in mammals : Elephant seals
Sent in a simple manor; Zebras lower ears when threatened or raise them when greeting.
Varies with intensity (the signal)
Chemical signals between indiv of same species
Chemical signals between different species
Four modes of mammal communication
Odor, Visual, Auditory, Tactile
Four types of "group-spacing"
1) Distance-increasing: Branch shaking means coming down, move 2) Distance-maintaining: Howler -> go away 3) Distance-reducing: "lost" call of cebus monkey 4) Proximity-maintaining: grooming.
Importance of recognition in communication
A lotta stuff
All aspects of conflict; attack, escape, etc.. Minus predation. Territorial, Dominance, Sexual, Parental Parent-offspring.
Exclusion of others from a place
Controlling the behavior of another individual (due to previous encounter)
Threats and punishments to obtain and remain mates
Attack intruders when young are present
Disciplinary action associated with weaning
Behavior intended to inflict noxious stimulation or destructin
Fighting over limited resources
Deprive others of resources w/o direct interactions (fruit eating bats and birds)
Organisms interact to reduce areas of resources for each other
Major histocompatibility complex: Self/non-self in immunte system, recognize things that aren't you.
Can detect differences in MHC through urine odor. Many mammals mate with diffrent MHC indiv
Perfumes, colognes, etc. Boost sexual attractivmeness
Four Dominance Schematics
1) Dominating the pack A ->BCD 2) Pecking Order A->B->C->D 3) Triangular Dominance C->A->B->C 4) A ->BC; BC->A
Coordination of sp together against A dom.. ex, elephant seals
Cons of Olfaction
Takes a long time to take effect, limited in message being given
Chemical Communication evolved early. Useful: Night or day uses, signal lasts for days, travel around solids. Cost effective.
Sound. Useful: Immediate response, fast transmission, effective night or day, produced by single organism, can travel around objects.
Cons of Auditory Cues
Worry about predators or prey hearing you
Travels much farther and faster underwater
Receiver locates signaler in precise space and time. Signals can be very subtle
Why Flagging Behavior (1-5)
1) Distract predators from others in group 2) Worn others of possible predators 3) Confuse predator if a lot of flags go up 4) Signals to predator that they have been seen 5) Eliciting pre-mature pursuit "go away"
