Abstract

Talijanska zidna gušterica, Podarcis Siculus i Dalmatinska zidna gušterica, Podarcis melisellesis su dvije vrste guštera iz porodice Lacertidae. Kada ove dvije vrste dijele isti habitat, P. Siculus nadjačava P. melisellesis kao dominantna vrsta, što obično dovodi do izumiranja P. melisellesis. U ovom diplomskom radu sam pokušavala utvrditi ponašanje tih vrsta guštera, Podarcis Siculus i Podarcis melisellesis u novom okruženju. Da bi se to postiglo, gledali smo razdoblje navikavanja u otvorenom prostoru i u radijalnom labirintu. Habituacija je vrlo jednostavan oblik učenja, u kojem je životinja, nakon razdoblja izloženosti poticaju, prestaje reagirati. Imali smo 14 uzoraka svake vrste, 7 ženki i 7 muškaraca. Svaki eksperiment je trajao 15 minuta. Imali smo 3 pokusa, a zatim usporedili prvi i treći pokus. Parametri interesa su vrijeme, vrijeme provedeno u središnjem odnosno vanjskim površinam i povratak u mjesto za skrivanje. Testirali smo za razlike u ponašanju između vrste i spolova.

Abstract (english)

The Italian wall lizard, Podarcis siculus and the Dalmatian wall lizard, Podarcis melisellesis are two lizards from the family of Lacertidae. When this two species share same habitat, P. siculus overpowers P. melisellesis as a dominant competitor, usually leading to extinction of P. melisellesis. In this Graduation thesis I was trying to establish the behaviour of these two species of lizards, Podarcis siculus and Podarcis melisellesis in a new environment. In order to do so, we observed habituation period in open field test and 8-arm radial maze. Habituation is an extremely simple form of learning, in which an animal, after a period of exposure to a stimulus, stops responding. We had 28 specimens of each species, 14 females and 14 males. Each experiment lasted 15min or maximum of 23 minutes. We had 3 trials and then compare first and third trial. Parameters of interest were latency time, time spent in the central vs. marginal area and returning into hiding place. We tested for the behavioural differences between the species and sexes.
