Journal: | Acta Zoologica Bulgarica | Abstract: | This study presents an overview of localities where the alien pond slider Trachemys scripta (Thunberg in Schoepff, 1792) (Emydidiae) and its subspecies, T. s. elegans (Wied-Neuwied, 1839), T. s. scripta (Thunberg in Schoepff, 1792) and T. s. troostii (Holbrook, 1836), has been introduced in Serbia and shows indication of its possible reproduction in this country. The number of the new reports of these turtles is almost equal to the number of previously published findings. Most introductions as well as the cases of possible reproduction (nest-digging females and hatchlings found) have been concentrated around the large urban hubs – Belgrade and Novi Sad cities, where the largest populations have been detected. Generally, the water bodies in the lowland habitats (less than 100 m a.s.l.) were proven to be much more vulnerable to the introduction of alien turtles – more than 73% of cases of introduction were detected at low altitudes. Previously unreported “substitute” subspecies (T. s. scripta and T. s. troostii) can hybridise with the red-eared slider (T. s. elegans) and possibly increase its invasive potential. We suggest stricter enforcement of the legislation, together with raising public awareness of the problem, eradication of the established populations and building turtle sanctuaries as an ethical and ecologically safe alternative for disposal of unwanted pets. |
