Several scenarios for its introduction to Fars Province are also proposed. Key words. Emys orbicularis persica, Emydidae, translocation, exotic, Arjan wetland, Fars Province, Iran.

The family Emydidae Rafinesque, 1815 comprises restricted to the Tigris River basin in southwest of the country a group of freshwater turtles of small and medium sizes (Kami et al. 2006, Fritz and Havaš 2007, Rastegar-Pouyani et al. characterized by a low 12th pair of marginal scutes. The ducts of 2008). the musk glands are present and are represented by a single (anterior) pair (Ananjeva et al. 2006, see more details in Vitt and Caldwell 2009). This family with 12 genera and 46 species is one of the most diverse and the most speciose families of the order Testudines Batsch, 1788 (Fritz and Havaš 2013) distributed in Europe to Ural Mountains and North America southward to eastern Brazil (Vitt and Caldwell 2009). With the exception of two species of pond turtles of the genus Emys, E. orbicularis (Linnaeus 1758), and E. trinacris (Fritz et al. 2005), the Emydidae is entirely a New World family (Ananjeva et al. 2006). The European pond turtles of the genus Emys Duméril, 1805, are turtles of a medium size leading an aquatic mode of life. Emys orbicularis (Linnaeus 1758) with eight described subspecies is a widely distributed Palearctic species as inhabits one of the largest distribution areas among the turtles of the world. The distribution area covers an extensive territory from southern, central and Eastern Europe, Asia Minor and north-western Africa to western Turkmenistan and western Kazakhstan in the east (Fritz 1998, Ananjeva et al. 2006, Van Dijk et al. 2012). Basic information on the general biology, taxonomy and morphology of Palearctic turtle species are readily available from the literature (e.g. Fritz 1998; Fritz et al. 1998; Mitrus and Zemanek 2000; Ananjeva et al. 2006; Fritz et al. 2007; Van Dijk et al. 2012). Iran hosts three taxa of freshwater turtles including Figure 1. Map of Iran shows natural Caspian Sea habitats (yellow the eastern pond turtle, E. o. persica, which is restricted to placemarks, 1-5) and introduction sites (red placemarks, 6, 7) for Emys northern Iran, the Caspian turtle, Mauremys caspica (Gmelin orbicularis persica. 1-5: Golestan, Mazandaran, Guilan, Ardebil and 1774, Geoemydidae) with three subspecies and a wide range in East Azerbaijan Provinces, respectively (Hezaveh et al., 2012); 6. northern and western Iran, and the Euphrates softshell turtle, Arjan wetland, 7.

Fars Province from other Iranian Provinces, especially north of Thus, the specimen languished, but was not forgotten, for nearly Iran, and different freshwater habitats of Fars Province, for sale three years, when in February 2014, it was checked by the first in pet shops especially for the Nowruz, Iranian Festival of the author and identified as E. o. persica. This specimen is deposited New Year. In one case in March 2011, the first author observed and cataloged in the Zoological Museum-Collection of the one of these illegal shipments of turtles in Lamerd Township Biology Department of Shiraz University (ZMCBSU), Iran as (Fig. 3b), a hot and dry area in southwest of Fars Province museum number of ZM-CBCU-R112. Some morphometric without the natural occurrence of any species of aquatic characters, as according to Terentev and Chernov 1949, of the Testudines. collected specimen are given in Table 1. Despite some observations of the eastern pond turtle of Fars The Dasht-e Arjan lake or Arjan wetland, 29°37'N, 51°59'E, is a Province in nature during the last few years by the authors and Ramsar Site, as well as one of the four internationally important local people nothing is still known about any stable population wetlands of the nine Biosphere Reserves of Iran, situated within of this taxon. Due to suitable environment of the Arjan wetland the Arjan Protected Area in the Zagros Mountains, 40-80 km such as extensive freshwater resources with rich bed of water west of Shiraz, the capital of Fars Province. The Dasht-e Arjan weeds and presence of enough foods such as different species of with an area about 2,200 ha, is a shallow, eutrophic, freshwater native fishes of different sizes (Table. 2), E. o. persica is lake with extensive reed-beds (Fig. 2b, Coad 2014). The lake lies expected to establish and extend its range to other freshwater in an enclosed basin and is fed by two large springs on its bodies of this basin and became as a natural element fauna western side and local run-off from winter rainfall and snow- within the next decades. For example, the Abu mullet, Liza abu, melt (Coad 2014). The lake margin and the spring-fed marshes an inhabitant of the brackish water of the endorheic basin of have Phragmites communis, Typha and Juncus along with Maharlu Lake has been translocated to the Parishan wetland aquatic vegetation (Fig. 2b).
