Each animal’s unique adaptations allow them to attempt to succeed in these tasks. Animals can use communication to aid them in their challenge for survival. The types of animal communication are as diverse as animals themselves and we are just beginning to uncover some of the fascinating secrets held within their communications. Communication by an animal is any behavior on one animal’s part that has an effect on the current or future behavior Audible communication is perhaps the of another animal. Communication can. easiest for us to identify but our take many forms that we can observe understanding of its intricacies is still and some mysterious forms that are not very basic.

    © Copyright, Princeton University Press. No part of this book may be distributed, posted, or reproduced in any form by digital or mechanical means without prior written permission of the publisher. 1 Introduction Whether signals are reliable or deceptive has been a central question in the study of animal communication in recent years. The crux of the issue is whether animal signals are honest, in the sense of conveying reliable informa­ tion from signaler to receiver, or deceitful, in the sense of conveying unreliable information, the falsity of which somehow benefits the signaler. This issue arises in a variety of contexts. When a male courts a female, do his signals honestly convey his quality relative to other males? Or does he exaggerate his quality in order to win over females that would otherwise choose some other male? When one animal signals aggressively in a contest over a resource, does the signaler honestly convey its likelihood of attack? Or does the signaler exaggerate that likelihood in order to intimidate competitors that would other­ wise defeat him? The question of reliability versus deceit arises even in interac­ tions that, on the face of things, seem to be predominantly cooperative. When an offspring begs for food from its parents, does it honestly convey its level of need? Or does the offspring exaggerate its need in order to get more food than the parents would otherwise provide? The issue of reliability and deceit in animal communication resonates with humanobservers for a variety of reasons. One is that the occurrence of deceit is fraught with moral implications.

    Tartu Semiotics Library 18 Tartu Tartu Semiotics Library 18 Animal umwelten in a changing world: Zoosemiotic perspectives represents a clear and concise review of zoosemiotics, present- ing theories, models and methods, and providing interesting examples of human–animal interactions. The reader is invited to explore the umwelten of animals in a successful attempt to retrieve the relationship of people with animals: a cornerstone of the past common evolutionary processes. The twelve chapters, which cover recent developments in zoosemiotics and much more, inspire the reader to think about the human condition and about ways to recover our lost contact with the animal world. Written in a clear, concise style, this collection of articles creates a wonderful bridge between Timo Maran, Morten Tønnessen, human and animal worlds.

    Behavior of the House Cricket, Acheta domesticus •••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••• Background The Study of Animal Behavior All animals interact with their environment, including individuals or groups of either the same or different species. These behavioral interactions, whether with the environment or other animals, have fascinated researchers for a long time. However, it was not until the early decades of the 20th century when the study of animal behavior gained a coherent conceptual framework and a clearly spelled out research program, which eventually developed into a discipline that we now call “classical ethology”. This field was internationally recognized in 1973 when the Nobel Prize in Physiology or Medicine was awarded to Karl von Frisch, Konrad Lorenz, and Nikolaas Tinbergen “for their discoveries concerning organization and elicitation of individual and social behavior patterns”. Many would argue that these three are the most prominent historical figures in the field of behavioral biology. Karl von Frisch pioneered the research on the communication mechanisms amongst bees about a food source, discovering the honeybee “dance language” (von Frisch, 1967). Konrad Lorenz conducted many studies examining instinctual and fixed action patterns of behaviors in animals as well as imprinting (Lorenz, 1952). Nikolaas Tinbergen examined the degree of behavioral responses to various stimuli in many animals; some behavioral responses could be elicited more strongly using an exaggerated
