Sažetak
The Nature park Kopački rit is recognised as an important habitat for two species of amphibians and one species of reptile: European fire-bellied toad (Bombina bombina), Danube crested newt (Triturus dobrogicus), and European pond turtle (Emys orbicularis). During 2021 to 2022 field surveys were conducted using standardised methods for studying batrachofauna and herpetofauna: visual point survey, funnel traps for amphibians, road transects and linear transect. In addition, a new non – invasive method for detecting elusive species was tested, environmental DNA (eDNA). eDNA is a revolutionary method designed to detect species from water, soil, and air samples that is already being utilized globally to detect specific species. Without direct specimen sampling, this method allows us to determine whether a single species or numerous species are present in a specific area of interest. During field surveys in 2021, 3 amphibian species and 3 reptile species were recorded. The most numerous amphibian group was the Pelophylax species complex (P. ridibundus, P. esculentus, P. kurtmuelleri and P. lessonae), 9 individuals of B. bombina and 4 Lissotriton vulgaris individuals. Reptiles were represented with 48 individuals of E. orbicularis, 6 individuals of Natrix tessellata and one individual of Natrix natrix. In 2022, a total of 87 E. orbicularis were recorded and no B. bombina was observed yet. Regarding reptiles, one individual of the N. natrix and two individuals of the Trachemys scripta were recorded. Futhermore, T. dobrogicus was not detected during the project. Consequently, water samples were collected and filtered from 10 different localities throughout the park to develop and test the utility of the eDNA method for T. dobrogicus. Research of T. dobrogicus is generally quite demanding, especially in an inaccessible habitat such as the floodplains of Nature Park Kopački rit. If this method is successful in detecting T. dobrogicus it can also be used to test for the presence and early detection of invasive species such as T. scripta complex.
