For reproduction, so Caudata as Ecaudata amphibians, compulsory need the presence of aquatic basins; of which distribution in Triturus cristatus population spreading area in „Codrii” reservation depends very much the reproduction and onthogenetical developmen of examened species. It was established that a determinate influence upon Triturus cristatus species reproduction strategy have the next two ecological factories: - the distribution in space of reproduction basins; - the terms and period duration of examined species reproduction in Central Codri habitats.After realized on ground investigation about Triturus cristatus population reproduction from Codri reservation we established that for this species, which refers to amphibian species with early and long reproduction is characteristic the reproduction strategy manifasted through male territorialisme and female atraction, through one complex realization of their courtation behavior acts.
