Social organization and communication of flying foxes focused on the genus Rousettus

Within the family Pteropodidae there are different types of social systems, depending on the species. Reproductive activity of Egyptian fruit bat (Rousettus aegyptiacus) is based on the latitude, when in milder latitudes individuals tend to be seasonally monoestry, southerly living individuals are less synchronous. Gestation lasts about four months and in most cases one young is born and mother cares about it. Egyptian fruit bats often inhabit caves, while there may live thousands of individuals and even more together. Pteropodidae are focused on plant food, which they choose according to the many criteria. Members of the genus Rousettus belong to the food generalists and their diet includes trees and herbs, from which they consume fruits, flowers, nectar, pollen, shoots and leaves. They were also observed by eating beetles of the family Scarabidae. Flying foxes of the genus Rousettus are special, because they orient by echolocation. They emit short broadband signals through the vibration of the language, whose length ranges from 50-100 s. From other chiropteran families they differ through the way of production the signals. In addition to echolocation senses of smell and sight are key in terms of communication. The smell is important mainly in attracting a partner, for mutual recognition between..
