The distribution of Simuliidae (Insecta, Diptera) species in Ankara Stream (Turkey) INTRODUCTION Simuliidae is a family of Diptera order with approximately 2163 species (2,151 living and 12 fossil) described species worldwide (Adler and Crosskey 2014). The larvae and pupae of blackflies are widespread and regular members of the benthic macroinvertebrate fauna of lotic ecosystems (Feld 2005 and Zhang et al. 1998). They inhabit most types of running waters and play a key role in running water ecosystems (Zhang et al. 1998). The densities of blackfly larvae and pupae are affected by various environmental variables and hydromorphological conditions of running waters (Lautenschlager and Kiel 2005, Kazancı 2006). Species of this family are highly sensitive to environmental changes (Feld et al. 2002). Ankara Stream is one of the most important tributaries of the Sakarya River. Altough the stream has been contaminated mainly by sewage and industrial waste water, it is an important freshwater source for the city of Ankara. The benthic macroinvertebrates of Ankara Stream are studied by Girgin and Kazancı 1994, Kazancı and Girgin 1996, Girgin 1997, Girgin et al. 1997, Girgin and Kazancı 1997, Kazancı et al. 1997, Kazancı and Girgin 1998, Girgin et al. 2003, Girgin and Kazancı 2006, Girgin et al. 2010. The objectives of the present study are to determine the Simuliidae fauna of Ankara Stream and tributaries and to determine species distribution in relation to aquatic habitat quality. MATERIALS AND METHODS Simuliidae individuals together with other benthic macroinvertebrates were collected from 6 sites between 1991 and 1992. The 6 sites are situated in Ankara Stream and tributaries. Samples of Site 1 were collected at two different months. Samples of Site 9 (May 92) and Site 18 were collected at three different months. Benthic macroinvertebrates were collected by a standard pond net. Simuliidae larvae were preserved in 80% ethyl alcohol and were identified to species level. The names and collection dates of investigated sites were given in Table 1. 159

The distribution of the Simuliidae species in Ankara Stream is given in Table 2. The highest species number obtained (3 species) in Site 9 (July 92) and Site 18 (July 92). Prosimulium tomosvaryi shows a European-Trans-Caucasian distribution (Seitz 1992). It prefers mainly betamesosaprobic and alphamesosaprobic environments (Car et al. 1995). This species was collected from Site 1 (May 92), Site 9 (May 92) and Site 14. The water qualities of Site 14, Site 9 (May 92) were alphamesosaprobic and Site 1 (May 92) was betamesosaprobic (Girgin and Kazancı 1994). In Turkey, Prosimulium tomosvaryi is known from Büyük Melen River, Sakarya River Basin and Eastern Black Sea region (Şirin 2002, Crosskey and Zwick 2007, Kazancı and Ertunç 2008a, Başören and Kazancı 2013). Simulium (E.) angustipes lives in small and nutrient-rich waters (Lechthaler and Car 2005). This species is wide-spread all over Europe (Crosskey and Howard 2004). It prefers mainly betamesosaprobic environments but it might also be encountered in alphamesosaprobic and oligosaprobic environments (Car et al. 1995). This species was collected from Site 18 (November 92). The water quality of this site was alphamesosaprobic (Girgin and Kazancı 1994). 160

Simulium (S.) ornatum can survive in polluted waters (Cupina et al. 2003). Furthermore, this species can be found in clean waters (Lechthaler and Car 2005). Substrate structure, water temperature and water discharge are not important for distribution of this species (Bernotiene 2006). This species is one of the most widespread blackfly species of Europe (Crosskey and Howard 2004) and it can be found all over the Palaearctic region. Its habitat preference is mostly alphamesosaprobic and betamesosaprobic habitats (Car et al. 1995). This species was collected from Site 2.

In Turkey, it is known from Büyük Menderes River Basin, Kızılırmak River Basin, Yeşilırmak River Basin, Sakarya River Basin, Yedigöller National Park and Eastern Black Sea region (Şirin 2001, Crosskey and Zwick 2007, Kazancı and Ertunç 2008a, b, Ertunç 2009, Kazancı and Ertunç 2010, Başören (Ertunç) and Kazancı 2011, 2012). Başören and Kazancı 2013). Simulium (W.) lineatum prefers mostly medium-sized and sand-bottom lowland rivers, and its habitat is hydromorphologically undisturbed sites (Feld 2005). This species is reported from most parts of Europe (Lechthaler and Car 2005). It prefers mainly betamesosaprobic environments but it occurs also in alphamesosaprobic environments (Car et al. 1995). This species was collected from Site 18 (April 92) and Site 18 (July 92). The water qualities of these sites were alphamesosaprobic (Girgin and Kazancı 1994).

ÖZGE BAŞÖREN, NİLGÜN KAZANCI AND SÖNMEZ GİRGİN Protected Area (Muğla Province), Yedigöller National Park and Eastern Black Sea region (Şirin 2001, 2002, Ertunç et al. 2008, Kazancı and Ertunç 2008a,b, Ertunç 2009, Kazancı and Ertunç 2010, Başören (Ertunç) and Kazancı 2011, 2012, Başören and Kazancı 2013). Simulium (W.) pseudequinum can live in a wide range of habitats and it is able to resist high water temperatures (Feld et al. 2002, Lautenschlager and Kiel 2005). This species shows an East-West European distribution and it is a common species in the southern Palaearctic region (Crosskey and Howard 2004). It prefers mainly betamesosaprobic and alphamesosaprobic environments (Car et al. 1995). This species was collected from Site 9 (July 92), Site 18 (July 92) and Site 18 (November 92). The water qualities of these sites were alphamesosaprobic (Girgin and Kazancı 1994). In Turkey, it is known from Altındere Stream (Trabzon Province, Maçka), Büyük Menderes River Basin, Çoruh River Basin, Kızılırmak River Basin, Fırat River Basin, Yeşilırmak River Basin, Namnam Stream, Sakarya River Basin, Seyhan River Basin, Köyceğiz Protected Area (Muğla Province), Zamantı River, Yedigöller National Park and Eastern Black Sea region (Clergue-Gazeau and Kazancı 1992, Şirin 2001, 2002, Crosskey and Zwick 2007, Ertunç et al. 2008, Kazancı and Ertunç 2008a,b, Ertunç 2009, Kazancı and Ertunç 2010, Başören (Ertunç) and Kazancı 2011, 2012, Başören and Kazancı 2013). CONCLUSION Eleven sites located on the Ankara Stream and its tributaries were characterized as betamesosaprobic and alphamesosaprobic and habitat characteristics of sites were suitable for 9 species (Prosimulium tomosvaryi, Simulium (E.) angustipes, Simulium (S.) argenteostriatum, Simulium (S.) bezzii, Simulium (S.) ornatum, Simulium (S.) trifasciatum, Simulium (W.) balcanicum, Simulium (W.) lineatum and Simulium (W.) pseudequinum). In other words, Blackfly (Diptera, Simuliidae) communities that inhabit Ankara Stream and tributaries include mainly betamesosaprobic and alphamesosaprobic species. Site 2, Site 1 (May 92) and Site 1 (November 92) closest to the headwater were affected by domestic waste and agricultural pollution. Site 11 was contaminated by the wastes of a milk factory. This site was also affected by domestic and agricultural pollution. Site 14, Site 9 (May 92), Site 9 (June 92) and Site 9 (July 92) were affected by domestic waste and by agricultural pollution. There is no major industrial waste in this area. Site 18 (April 92), Site 18 (July 92) and Site 18 (November 92) were contaminated by the wastes of a integrated meat plant and by fertilizers (Girgin and Kazancı 1994). 164
The distribution of Simuliidae (Insecta, Diptera) species in Ankara Stream (Turkey) The environmental impacts of intense and increasing pollution are observed in Ankara Stream and its tributaries. Accordingly, community structures of Simuliidae and other benthic macroinvertebrates were negatively affected by this pollution. Therefore, treating the wastes from factories and from other plants which cause pollution has great importance and more research is required to prevent this situation. REFERENCES Adler, P.
