Persian onager found in desert steppes. Their largest population is found in Khar Turan National Park. The Persian onager is listed as endangered by IUCN Red List, as it is close to extinction. Currently, poaching for meat and hides, competition with livestock, and drought are the greatest threats to this species. Asiatic wild asses are highly and legally protected; hunting them is forbidden. The European Endangered Species Programme reserved for European Association of Zoos and Aquaria is helping save the Persian onager from extinction, by breeding them in captivity and reintroducing them to their former ranges, including in new locations once inhabited
Animal communication individual. The altered signal provides information that can indicate food, predators or conspecifics. Because the sender and receiver are the same animal, selection pressure maximizes signal efficacy, i.e. the degree to which an emitted signal is correctly identified by a receiver despite propagation distortion and noise. There are two types of autocommunication. The first is active electrolocation found in the electric fish Gymnotiformes (knifefishes) and Mormyridae (elephantfish) and also in the platypus ("Ornithorhynchus anatinus"). The second type of autocommunication is echolocation, found in bats and toothed whales. There are many functions of animal communication. However, some have been studied in
