dc.description.abstractWe studied male and female one-year reproductive, fat body and liver cycle of the common wall lizard (Podarcis muralis muralis) from the urban and suburban localities of Belgrade. The minimum size at which females attain sexual maturity was between 49.78 and 51.25 mm of the snout-vent length. Vitellogenesis started at the end of March. The size and number of vitellogenic follicles varied considerably during the season. Increase in the female size leads to a significant increase in number but not in size of vitellogenic follicles. Females with oviductal eggs were found from late May to late July. Two clutches with mean size of 3.5 ± 0.31 were laid in 1994. We found a significant positive correlation between female size and oviductal clutch size, while partial correlation between SVL and mean egg volume, as well as between clutch size and mean egg volume was insignificant. Relative oviductal clutch mass had the mean value of 0.17 ± 0.01, and was not correlated with female size. Testicles and epididymides exhibited maximal weight during April-June, and minimum in late July. The increase in male SVL lead to a significant increase in testicular and epididymal mass. Viable spermatozoa were produced from March to July. Fat bodies and liver of males were the smallest during the mating period while female fat bodies and liver decreased in weight during vitellogenesis. Mass of fat bodies and liver were significantly positively correlated with SVL in both sexes.en
dc.description.abstractU ovom radu je praćen jednogodišnji reproduktivni ciklus zidnog guštera (Podarcis muralis) na teritoriji grada Beograda. Minimalna veličina tela na kojoj ženke postaju polno zrele je bila između 49.78 i 51.25 mm. Vitelogeneza počinje krajem marta, dok broj i veličina vitelusnih folikula značajno varira tokom reproduktivne sezone. Veličina ženki je pozitivno korelisana sa brojem, ali ne i sa veličinom vitelusnih folikula. Ženke s oviduktalnim jajima su nalažene od kraja maja do kraja jula. Tokom ispitivane sezone 1994. godine postojala su dva legla, sa prosečnom veličinom od 3.50 ± 0.31 jaja. Ustanovljena je značajna pozitivna korelacija između veličine ženki i veličine legla, dok parcijalna korelacija između veličine ženki i prosečne zapremine jaja, kao i između veličine legla i prosečne zapremine jaja nije bila značajna. Prosečna relativna masa oviduktalnog legla je bila 0.17 ± 0.01 i nije bila u korelaciji sa veličinom tela ženki. Kod analiziranih mužjaka testisi i epididimisi su imali najveću masu u periodu april-juni, a najmanju krajem jula. Porast mase testisa i epididimisa je u direktnoj vezi sa veličinom tela mužjaka. Vijabilni spermatozoidi su nalaženi od marta do jula. Masa masnih tela i jetre kod mužjaka je bila najmanja u vreme parenja, dok se masa masnih tela kod ženki smanjivala tokom vitelogeneze. Značajna pozitivna korelacija između veličine tela i mase masnih tela i jetre je uočena kod oba pola.sr
