Abstract

Ostvarena trofička niša opisuje prehranu jedne vrste u prirodnom okruženju i uglavnom je ograničena dostupnošću hrane. Prirodna prehrana može se procijeniti različitim metodama, ali najčešće se koristi analiza prehrane temeljena na DNA. Zodarion rubidum (Simon 1914) je, za razliku od većine vrsta paukova, opisan kao stenofagni predator specijaliziran za prehranu baziranu na mravima. Ipak, njegova prirodna prehrana uglavnom je nepoznata i ne postoje saznanja o prehrambenim preferencijama tijekom... More ontogenetskog razvoja. Cilj ovog istraživanja je utvrditi postoji li promjena u prehrambenim preferencijama tijekom ontogeneze Z. rubiduma i postoji li razlika u prehrani između spolova. Osim toga, proveden je pokus kontroliranog hranjena kako bi se odredio potencijal metode analize prehrane temeljene na DNA i kako bi se procijenilo vrijeme u kojem se DNA plijena može detektirati unutar predatora.

Abstract (english)

The realized trophic niche describes the natural diet of a species and is mostly limited by the prey availability. The natural diet can be assessed through various methods, but the most commonly used method is DNA-based diet analysis. Zodarion rubidium (Simon, 1914) is, unlike most spider species, described as a stenophagous predator specialized in foraging ants. Still, his natural diet is for the most part unknown and there is no knowledge of prey preferences during ontogenetic development.... More The main goal of this research is to determine whether there is a shift in prey preferences during Z. rubidum’s ontogenesis and if there is a difference in the diet between sexes due to sexual dimorphism. In addition, a feeding trial was performed to assess the potentials of DNA-based diet analysis and to estimate the time at which prey-DNA can be detected. Less
