Abstract

Primorska gušterica, Podarcis Sicula i krška gušterica, Podarcis melisellesis su dvije vrste gušterica iz porodice Lacertidae. Kada ove dvije vrste dijele isto stanište, P. sicula nadjača P. melisellesis kao dominantna vrsta, što obično dovodi do istiskivanja P. melisellesis. U ovom diplomskom radu sam pokušavala utvrditi utječe li na to način na koji te dvije vrste pretražuju prostor u kojem žive. Da bi to uspjela uzela sam 14 jedinki svake vrste, 7 ženki i 7 mužjaka te ih podvrgnula testu otvorenog polja na kojem se nalazilo 9 kamena, a iza jednog od njih je bila hrana te pratila kako pretražuju prostor. Svaki pokus je trajao 10 min. Svaka jedinka je bila podvrgnuta istom pokusu 10 dana za redom. Parametri istraživanja su bili kretanje, smjelost i pretraživanje prostora s obzirom na hranu .Gledali smo razlike između vrsta, spola i dana izvođenja pokusa.

Abstract (english)

Italian wall lizard, Podarcis sicula and Dalmatian wall lizard, Podarcis melisellesis are two species from family Lacetidae. When these two species share the same habitat, P. sicula overpower P. melisellesis as the dominant competitor, which usually leading to the extinction of P. melisellesis. In this Graduation thesis I was trying to determine whether is this affected by their exploratory activity in the habitat they live in. In order to do so, I took 14 individuals of every species, 7 females and 7 males, subjected them to an open field test with 9 stones, and behind one of them there was food, and tracked how they explored the space. Each test lasted for 10 minutes. Each individual was subjected to the same test for 10 days in a row. The parameters of the study were movement, the boldness and the exploring of space according to food in it. I looked at the differences between species, sex, and day of the experiment.
