Abstract

U Hrvatskoj živi 20 vrsta vodozemaca, što našu zemlju svrstava u sam vrh europskih zemalja po bioraznolikosti vodozemaca. Razlozi ugroženosti vodozemaca u svijetu, pa i u Hrvatskoj, su brojni. Na prvom mjestu je uništavanje staništa krčenjem i isušivanjem zbog čega ona postaju nepogodna za život vodozemaca. Takvim zahvatima se staništa ujedno i prostorno odvajaju što onemogućava normalno kretanje populacija vodozemaca između staništa (što je posebno važno tijekom ciklusa razmnožavanja). Iako vodozemci jesu kopnene životinje, njihov život je vezan uz vodu, prvenstveno radi razmnožavanja. Gotovo nikada samo jedan od navedenih razloga ne ugrožava populacije vodozemaca već u pravilu dolazi do zajedničkog djelovanja barem nekoliko od činitelja, što onda pogubno djeluje na preživljavanje vodozemaca.Sve vrste vodozemaca u Hrvatskoj nalaze se u nekoj od kategorija zaštite. U ovom radu izložen je kratki pregled biologije vrsta vodozemaca koji žive u Hrvatskoj te njihove rasprostranjenosti.

Abstract (english)

There are 20 species of amphibians in Croatia, which makes our country one of the most biodiverse european countries when it comes to amphibians. Reasons for amphibians endangerment in Croatia, as well as around the world, are numerous. Main reason is habitat ravage by clearing and draining which makes them unsuitable for amphibians to inhabit. By interventions like this habitats are also being spatially separated which prevents normal moving of amphibian populations between habitats (this is especially important during mating cycle). Although amphibians are terrestric animals their life is related to water, especially due to mating. It is almost never one of indicated reasons that endanger amphibian populations; normally cumulative effect of at least several factors leads to endangerment, which has fatal effect on survival of amphibians. All amphibian species in Croatia are placed in one of protection categories. In this work a short review of biology of amphibians species in Croatia and their range is given.
