Document Summary

Signals can be sent through many different channels: types of signals, positive: mutualistic (cooperative), altruistic, negative: manipulative, spiteful.

Qualitative aspects of information transmission: ritualization, complex communication behaviour, originated from other functions such as: thermoregulation, maintenance behaviors etc, ex: piloerection (standing of hairs due to stimuli such as cold, or result of fear) What can signals say to receiver: potential message information, recognition of social groups members, mate attraction, courtship and act of mating, maintaining social bond, alarm, aggregation, agonistic encounters, share information about resources. Many species maintain social bonds: communication between members of social group can help maintain social bonds, largely tactile: resting together, nuzzling, grooming each other, allogrooming: social grooming, can be for hygiene or conflict resolution (appeasement) Agonistic encounters in wolves: communication can also be part of aggressive interactions (conflict, signals can convey, aggression (threats, attacks, submission (appeasement, avoidance)
