Abstract	U ovom radu obrađena je invazija divovske gubavice (Rhinella marina) u Australiji, koja je započela 1935. godine. Vrsta je unesena u svrhu biološke kontrole štetnika na poljima šećerne trske na prostoru Queenslanda. Divovska gubavica je autohtoni vodozemac na području Južne Amerike. Ova vrsta poznata je po bufotoksinu, smrtonosnoj tvari koju izlučuje kada se osjeća ugroženo. Nedugo nakon uspostave populacije, divovske gubavice (R. marina) krenule su se nekontrolirano širiti duž obale sjeverne i istočne Australije. Kroz godine zabilježen je porast u brzini širenja, pogotovo u jedinki u Sjevernoj Australiji. Adaptivne i fenotipske promjene opisane u ovom radu su odgovorne za ubrzanje širenja ove vrste duž njenog invazivnog areala. Navedene promjene su posljedica ekstremnih klimatskih uvjeta na koje divovske gubavice (R. marina) nailaze daljnjim širenjem. Na promjene je utjecao i manjak genetske raznolikosti unutar populacija na invazivnoj fronti na sjeveru zemlje.
Abstract (english)	This paper explores the invasion of the cane toad (Rhinella marina) in Australia, which began in 1935. The species was introduced as an agent of biological control of sugar cane pests on plantations in Queensland. Shortly after population establishment, cane toads began rapidly spreading along the coast of north and east Australia. Over the years, dispersal rate increase was documented, specifically in individuals from Northern Australia. Adaptive changes as well as changes in phenotype, which are further explored in this paper, were responsible for dispersal rate increase of this species along its invasion range. These changes were caused by extreme climate conditions with which cane toads (R. marina) are faced during their dispersal. The changes were also caused by a lack of genetic diversity in populations on the invasion front in the north part of the country.
