Abstract

Eholokacija je biološki sonar koji koriste neki viši kralježnjaci kako bi si olakšali život u okolini u kojoj žive. Uglavnom ju koriste za pronalazak hrane no i za međusobnu komunikaciju i dobivanje percepcije okoline u kojoj žive. Emitiraju zvučne valove u okoliš i primajući jeku stvaraju sliku svoje okoline u glavi. Za to su se morali i prilagoditi na različite načine što sam navela u poglavljima vezanim za pojedine vrste. U ovom radu sam stavila naglasak na šišmiše i dupine (kitovi zubani) jer je kod njih eholokacija najviše istražena. Kod ptica je dosta istražena no samo mali broj vrsta se njome koristi pa ju je teško proučavati jer te životinje žive na nepristupačnim mjestima. No kod rovki znanstvenike čeka još puno posla jer se o njihovom korištenju eholokacije zna najmanje.

Abstract (english)

Echolocation is the biological sonar used by some higher vertebrates that make their lifes easier in the region in which they live. It mainly used for finding food but also for communication and getting the perception of the environment in which they live. They emit sound waves into the environment and receiving the echo create a picture of your surroundings in mind. To do this they had to and adapt in different ways as I stated in the chapters relating to particular species. In this seminar, I put emphasis on bats and dolphins (toothed whales) because their echolocation is most researched. In birds it is also much explored, but only a small number of species use it and it is difficult to study because these animals live in remote areas. But with shrews scientists have a lot of work because their use of echolocation we know at least.
