Abstract
This study is combined the data from two different studies that carried out different regions and time, presenting some information on the population structure (dominance, local distribution etc.) of Potamopyrgus antipodarum (Gray, 1843). According to our data, this species was found in the four different localities in the Delice River with various population densities. However, only of small population was found in the Kocabaş Stream. This species was the second dominant species in the Delice River with 31.43 % after Physella acuta (Draparnaud, 1805) (46.88%). On the other hand, the species was not reached noticeable aggregates in the Kocabaş Stream. In this paper, supporting factors that paving the way P. antipodarum invasion are discussed for the study area.
Highlights
The New Zealand mud snail, Potamopyrgus antipodarum (Gray, 1843), is a truncatelloidean gastropod that can be able to tolerate a wide range of abiotic conditions from coastal estuaries to freshwater ecosystems (Gérard et al 2003)
This study is combined the data from two different studies that carried out different regions and time, presenting some information on the population structure of Potamopyrgus antipodarum (Gray, 1843)
In Turkey, occurrence of P. antipodarum has been known from various freshwater ecosystems and only one coastal marine area in the western and southern Anatolia since 1980 (Bilgin 1980; Ustaoğlu et al 2001a, b; Ustaoğlu et al 2003; Özbek et al 2004; Kalyoncu et al 2008; Kılıçarslan and Özbek 2010; Yıldırım et al 2006; Kebapçı and Yıldırım 2010; Gürlek 2015; Odabaşı and Arslan 2015)
Summary
The New Zealand mud snail, Potamopyrgus antipodarum (Gray, 1843), is a truncatelloidean gastropod that can be able to tolerate a wide range of abiotic conditions from coastal estuaries to freshwater ecosystems (Gérard et al 2003). It is known as an invasive worldwide that the current expansion comprises several continents including Europe, mainland Australia and Tasmania (Ponder 1988) and North America (Bowler 1991). In Turkey, occurrence of P. antipodarum has been known from various freshwater ecosystems and only one coastal marine area in the western and southern Anatolia since 1980 (Bilgin 1980; Ustaoğlu et al 2001a, b; Ustaoğlu et al 2003; Özbek et al 2004; Kalyoncu et al 2008; Kılıçarslan and Özbek 2010; Yıldırım et al 2006; Kebapçı and Yıldırım 2010; Gürlek 2015; Odabaşı and Arslan 2015). This study aimed to evaluate the mollusc fauna and demonstrate the population structures of P. antipodarum inhabiting in these streams, we evaluated the invasive characteristics of this species in studied areas
