- Abstract
On 25 October 2020 we studied the diet of two Salamandra salamandra populations from Domogled - Valea Cernei National Park. Totally, we collected 37 individuals from two habitats, one situated near a brook, and another without a permanent water course. The number of prey taxa consumed in those two habitats was equal (18), as the prey taxa were generally the same in both habitats. The highest percentage abundance and frequency of occurrence was registered by Gastopoda Limacidae. Near the brook, prey taxa related with humidity were dominant. Unlike these, in the other habitat, fire salamanders consumed more preys not related with humidity, smaller in size, with a hard and more chitinous body, fact which increased the number of preys / individual and food diversity. This indicates that habitat differences (even if both are favourable for S. salamandra) modify the species` food composition, which, being opportunistic, feeds with the more accessible preys in each habitat. Although the study was performed at the end of October, all fire salamanders had stomach contents, and the prey taxa were generally the same consumed in other periods and regions from the country.
