Abstract

Magnetizam je skup pojava od velikog značaja za naš planet. Njegova veza sa živim bićima prilično je očaravajuća, no i dalje relativno nejasna. Ptice (AVES) su u tom kontekstu na naprednijoj razini, jer se zahvaljujući vrećicama s mineralima željeza u gornjem dijelu kljuna lako orijentiraju i primaju složene vrste podražaja. Stoga je svrha ovog rada bila pokušaj da se na temelju spoznaja o mineralnim vrećicama kod recentnih ptica upoznaju neke od najčešćih fizikalnih metoda istraživanja, radi moguće primjene u detekciji i kod fosilnih ptica.

Abstract (english)

Magnetism is a phenomenon of great importance for our planet. Its connection with living beings is quite astonishing, but still pretty unclear. In this context, birds (AVES) seem a bit advanced, thanks to iron-mineral patches, which enable them to navigate through air and receive series of complex stimuli. Therefore, the purpose of this thesis was an attempt to clarify most common physical methods used in scientific research, based on known facts about iron-mineral patches for possible analogical application in fossil birds.
