Key points • Communication is when one animal transmits information to another animal causing some kind of change in the animal that gets the information. • Communication is usually between animals of single species, but it can also happen between two animals of different species. • Animals communicate using signals, which can include visual; auditory, or sound-based; chemical, involving pheromones; or tactile, touchbased, cues. • Communication behaviors can help animals find mates, establish dominance, defend territory, coordinate group behavior, and care for young. Introduction Have you ever wondered how ants follow what seem to be invisible trails leading to food? Why male dogs mark their territory by peeing on bushes and lampposts when you take them for walk? What birds are saying to one another when they chirp outside your window? 2 Name: Communication takes many forms Communication—when were talking about animal behavior—can be any process where information is passed from one animal to another causing change or response in the receiving animal. Communication most often happens between members of species, though it can also take place between different species. For instance, your dog may bark at you to ask for treat! Some species are very social, living in groups and interacting all the time; communication is essential for keeping these groups cohesive and organized. However, even animals that are relative loners usually have to communicate at least little, if only to find mate. What forms can communication behaviors take? Well, animal sensory systems vary quite great deal. For instance, dog sense of smell is 40 times more acute than ours! Because of this sensory diversity, different animals communicate using wide range of stimuli, known collectively as signals. Below are some common types of signals: • Pheromones—chemicals • Auditory cues—sounds • Visual cues • Tactile cues—touch In some cases, signals can even be electric! Where does this diversity of communication behaviors come from? Like other traits, communication behaviors—and/or the capacity for learning these behaviors—arise through natural selection. Heritable communication behaviors that increase an organism likelihood of surviving and reproducing will tend to persist and become common in population or species. In the rest of the article, well look at one example of the many ways that animals can communicate with one another. 3 Name: Auditory signals Auditory communication—communication based on sound—is widely used in the animal kingdom. Auditory communication is particularly important in birds, who use sounds to convey warnings, attract mates, defend territories, and coordinate group behaviors. Some birds also produce birdsong, vocalizations that are relatively long and melodic and tend to be similar among the members of species. Many non-bird species also communicate using sound: • Monkeys cry out warning when predator is near, giving the other members of the troop chance to escape. Vervet monkeys even have different calls to indicate different predators. • Bullfrogs croak to attract female frogs as mates. In some frog species, the sounds can be heard up to mile away! • Gibbons use calls to mark their territory, keeping potential competitors away. paired male and female, and even their offspring, may make the calls together. Water, like air, can carry sound waves, and marine animals also use sound to communicate. Dolphins, for instance, produce various noises—including whistles, chirps, and clicks—and arrange them in complex patterns. The idea that this might represent form of language is intriguing but controversial. 4 Name: What is communication used for? As the examples above illustrate, animals communicate using many different types of signals, and they also use these signals in wide range of contexts. Here are some of the most common functions of communication: • Obtaining mates. Many animals have elaborate communication behaviors surrounding mating, which may involve attracting mate or competing with other potential suitors for access to mates. • Establishing dominance or defending territory. In many species, communication behaviors are important in establishing dominance in social hierarchy or defending territory. • Coordinating group behaviors. In social species, communication is key in coordinating the activities of the group, such as food acquisition and defense, and in maintaining group cohesion. • Caring for young. Among species that provide parental care to offspring, communication coordinates parent and offspring behaviors to help ensure that the offspring will survive. As these examples show, communication helps organisms interact to carry out basic life functions, such as surviving, obtaining mates, and caring for young. 5 Name: Frage 1 Was ist Kommunikation im Tierreich?
