The current distribution of pond slider Trachemys scripta (Reptilia: Emydidae) in Croatia | Razširjenost gizdave želve Trachemys scripta (Reptilia: Emydidae) na Hrvaškem

Inglés. The pond slider Trachemy scripta was one of the most commonly exported turtles until the last decade and often released into the wild outside its native range. It was introduced to Europe, Africa, South America and Asia and included on the EU list of 100 World's Worst Invasive Alien Species and the List of invasive alien species of Union concern. The import of the subspecies Trachemys scripta elegans into Europe and Croatia has been banned for some time, but the number of specimens recorded in nature is still increasing. In this paper we present 45 new localities were the species was observed in Croatia, which makes a total of 84 known localities. Most of the records, 58%, are in the Continental biogeographical region and the rest in the Mediterranean. It has not yet been recorded for the Alpine biogeographical region. Most records (42%) come from ponds. Three new sightings of females digging nests, laying eggs and sightings of hatchlings were recorded, suggesting successful reproduction of the species. Further surveys of this alien species in Croatia are needed.

Esloveno. Gizdava želva Trachemy scripta je bila v zadnjem desetletju ena izmed najpogosteje izvoženih želv iz Amerike in s strani lastnikov pogosto izpuščena v naravno okolje zunaj njene naravne razširjenosti. Vnesena je bila v Evropo, Afriko, Južno Ameriko in Azijo. Vključena je na Seznam 100 najinvazivnejših tujerodnih vrst sveta in Seznam invazivnih tujerodnih vrst Evropske unije. Uvoz podvrste rdečevratke Trachemys scripta elegans je bil v Evropo in Hrvaško prepovedan, vendar se kljub temu število zabeleženih primerkov v naravi povečuje. V prispevku predstavljamo 45 novih lokalitet, kjer je bila vrsta opažena. Skupno je tako za Hrvaško znanih 84 lokalitet o pojavljanju te vrste. Največ najdb (58 %) je iz kontinentalne geografske regije, preostanek pa iz mediteranske. V alpski geografski regiji vrsta še ni bila potrjena. Večina najdb oz. opazovanj (42 %) je z ribnikov. Poročamo tudi o treh novih opažanjih izvaljenih mladičev ter samic, ki kopljejo gnezdo in odlagajo jajca. Potrebne so nadaljnje raziskave o tej tujerodni invazivni vrsti na Hrvaškem.
