Abstract

Lombardijsku žabu ubrajamo među rizične vrste s opasnošću od izumiranja. Jedan od glavnih utjecaja na smanjenje broja jedinki je i nestanak pogodnih staništa. Ovaj je rad načinjen kako bi se dobio uvid imaju li zahvati na vodenim tijelima utjecaj na brojnost lokalne populacije i u kojoj mjeri. Uspoređeni su regulirani i neregulirani tokovi koje ona koristi kao mrijestilište. Uspoređivan je broj mrijesta po metru u te dvije vrste tokova. Došlo se do zaključka kako lombardijska žaba preferira neregulirane tokove čije su karakteristike veća zasjenjenost, više obalnog drveća i granja u vodi, veći nagib obale i konduktivitet te manje vegetacije na obali i površini vode te niža temperatura vode nego kod reguliranih mrijestilišta.

Abstract (english)

Italian agile frog is a vulnerable species with a decresing population trend. This decrese in numbers is largely due to habitat loss. In this thesis I tried to determine what is the impact of a large number of modifications of water bodies on local populations of Italian agile frog. I compared regulated and nonregulated spawning sites. By comparing the number of spawn between two types of water bodies we concluded that this species prefers nonregulated sites wich have higher percentage of shadow, more trees on shores and branches in water, steeper shores and higher conductivity. Also they have less low vegetation on shores, less surface vegetation and lower water temperatures.
