Biological Aggression of the Introduced Red-Eared Slider, Trachemys scripta elegans (Wied, 1939) (Testudines: Emydidae) in Iran

Naeim Moradi, Nasrullah Rastegar-Pouyani


The red-eared slider, Trachemys scripta elegans (Wied, 1939), a subspecies indigenous to the southern United States has been introduced to various countries including Iran. During fieldwork in June 2012, a population of red-eared sliders was observed in Shoormast Lake, Mazandaran Province. The red-eared slider competes for food and space with a native turtle (Emys orbicularis persica Eichwald, 1831). Detailed studies of potential impacts of this aggression on the environment are still lacking.
