A checklist for zooplankton (Rotifera, Copepoda, Cladocera) of European Turkey inland waters
Ege Journal of Fisheries and Aquatic Sciences, 2014
Türkiye'nin Avrupa kısmı, Avrupa ile Asya kıtalar arasında geçiş bölgesi oluşturması nedeniyle her iki kıtanında türlerine ev sahipliği yapmaktadır. Ancak şu ana kadar Anadoludan ayrı olarak Türkiye Avrupası zooplanktonik organizmaların tür listesi çıkarılmamıştır. Bu nedenle bölgede bu güne kadar bu konuda yapılan araştırmaların tümü incelenmiştir. 1940'tan bu yana yapılan araştırmaların incelenmesi sonucunda 138 Rotifera, 53 Copepoda ve 65 Cladocera olmak üzere 256 tür listelenmiştir.

Taxonomy, distribution, and ecology of crustacean zooplankton in trough waters of Ankara (Turkey)
TURKISH JOURNAL OF ZOOLOGY, 2014
Introduction Artificial habitats have increased in number rapidly due to human activities, dramatically affecting natural habitats. For example, they can cause habitat and species loss (Külköylüoğlu, 2003). Troughs are one example of artificial structures that alter natural water bodies to artificial forms. They are built by converting springs or groundwater (Külköylüoğlu et al., in press). Troughs are used to store water for animals and drinking water for villagers, and for irrigation. Modification of a water body by using an artificial structure is a common method for increasing biodiversity in fresh or marine waters (Bulleri and Chapman, 2004; Burt et al., 2009). Artificial reefs, for example, are made from truck tires or concrete blocks (Lim et al., 1976), and from sticks, poles, and bundles of brushes (Polovina, 1991) to increase fish diversity. Artificial beds constructed from plastic lead to increases in the growth of macro-algae (Godoy and Coutinho, 2002). Considering troughs, there is a single study, by Külköylüoğlu et al. (in press), who investigated the distribution and ecology of Ostracoda from trough waters. However, there is no study about the effect of troughs on zooplankton biodiversity. If troughs support diversity for animals and plants, they could be called "artificially natural habitats" (Külköylüoğlu, pers. comm.). Zooplanktons are small microscopic organisms that can inhabit a variety of aquatic habitats. They have an important position in aquatic food chains as energy transmission from primary producers to the top trophic levels, i.e. predatory fishes and marine mammals (Sommer and Stibor, 2002). Zooplanktons are affected by environmental conditions and can rapidly respond to environmental changes (Dodson and Frey, 2001; Williamson and Reid, 2001; Dodson et al., 2005).The 3 main groups of zooplanktons are Rotifera, Cladocera, and Copepoda. In this study, we worked with 2 groups (Copepoda and Cladocera). As far as we know, there has been no extensive geographical study on the zooplankton composition of the troughs, as much of the knowledge about zooplanktons is confined to specific locations or habitats. Thus, this is actually the first extensive study on zooplanktons Abstract: Troughs are one of the main components of villages in Turkey. They are constructed by converting springs or underground waters. Until now, there has been no extensive study investigating the composition and diversity of trough zooplankton species. In order to contribute knowledge on the zooplanktons in troughs, 142 troughs were randomly sampled from 17 districts in Ankara Province between 22 June and 3 July 2011. A total of 18 zooplanktons including 11 Copepoda and 7 Cladocera species were determined. Twelve of the 18 (Paracyclops chiltoni, Paracylops fimbriatus, Paracyclops imminutus, Tropocyclops prasinus, Diacyclops bisetosus, Acanthocyclops vernalis, Canthocamptus staphylinus, Attheyella crassa, Bryocamptus minutus, Macrothrix hirsuticornis, Oxyurella tenuicaudis, Moina macrocopa) are new records for Ankara. Paracyclops imminutus was reported for the third time in Turkey in the last 50 years. UPGMA illustrated 4 main clustering groups of species corresponding to some of their ecological characteristics. Poisson distribution analysis showed almost random distribution of species among the troughs (s 2 /µ = 1.04). With their cosmopolitan characteristics, 3 species (M. hirsuticornis, E. serrulatus, and C. sphaericus) are the most common species. Their ecological tolerance and optimum values were higher than the mean tolerances for different environmental variables. The results show that troughs may provide suitable conditions for zooplankton species.
To determine zooplankton fauna of streams flowing into Darlık Reservoir, which supports important part of drinking water demand of Istanbul, zooplankton samples were monthly taken from 5 selected sampling stations between October 2008 and September 2010. The zooplankton community of the study area is composed of mainly Rotifera, Copepoda and Cladocera groups. During the study period a total of 39 taxa was observed, and 25 taxa of Rotifera, 7 taxa of Copepoda and 7 taxa of Cladocera were identified. Rotifera comprised 47.8%, Copepoda 43.9% and Cladocera 8.3% of the total zooplankton. The Shannon-Wiener diversity index values fluctuated in the range of 2.4 and 3.1 for stations. Zooplankton diversity index varied seasonally between 1.1-3.4. Generally, the higher values and higher temperature showed a higher zooplankton diversity indexes. In this study, also dissolved oxygen, conductivity, pH and water temperature were determined and results were determined at the suitable intervals for habitat choice of identified zooplankton species. All zooplankton species identified are the first record for the study area.
Zooplankton of Hancağız Dam Lake (Gaziantep - Turkey)
Survey in Fisheries Sciences, 2014
Zooplankton samples were taken seasonally from Hancağız Dam Lake between April 2012-May 2013 period. During the study, a total of 52 species (34 belong to genus Rotifera, 11 to Cladocera and 7 Copepoda) were found in Hancağız Dam Lake. Based on the number of individuals, rotifers were the dominant group in the dam lake (65.4%) followed by Cladocera (21.2%) and Copepoda (13.4%). All of the zooplanktonic species have been detected for the first time in Hancağız Dam Lake. The datas determined from the zooplankton community in Hancağız Dam Lake wereanalysedbyShannonWienerspeciesrichnessindex (H ı), Margalef diversity index(D) and Sorenson similarity index. H ı value was found highest with 3.73 in spring. D index value was calculated in its highest level in spring with 6.31.

A Study on Zooplankton Fauna and Some Water Quality Parameters of Kozan Dam Lake (Adana, Turkey)
Journal of Limnology and Freshwater Fisheries Research, 2019
Some water quality parameters (Secchi disk depth, water temperature, dissolved oxygen, pH, conductivity, chlorophyll a, NO2-N, NO3-N, NH4-N, PO4-P) and zooplankton fauna were determined in the Kozan Dam Lake. While the quality of the reservoir water was first class water in terms of temperature, dissolved oxygen, NH4-N, PO4-P, it was second-class water in terms of conductivity, pH, NO3-N. In total, 50 zooplankton species belonging to 26 families were determined (29 species belonging to 17 families from Rotifera, 15 species belonging to 7 families from Cladocera and 6 species belonging to 2 families from Copepoda). Brachionidae (Rotifera) was the most species rich family with 7 species, followed by Chydoridae (Cladocera) and Cyclopidae (Copepoda) with 6 and 5 species respectively. The most dominant species were Synchaeta pectinata (38.33%) from Rotifera, Bosmina longirostris (5.71%) from Cladocera and Cyclops vicinus (0.67%) from Copepoda. At the same time, the species found in every month were Asplanchna priodonta, Polyarthra dolichoptera, Bosmina longirostris, Ceriodaphnia pulchella, Cyclops vicinus and Diacyclops bicuspidatus. In the study, Rotifera was the most abundant group with 67%, followed by Cladocera with 29% and Copepoda with 4%. On the other hand, total Rotifera was found mostly in December (10099 individual/ m 3), Cladocera in January (4928 ind./m 3) and Copepoda in September (1091 ind./m 3).
Marine and Life Sciences
Some water quality parameters (water temperature, conductivity, dissolved oxygen and pH) and zooplankton fauna were investigated in 10 water wells where the study was conducted. In this study, 14 species of Rotifera (46.67%), 10 species of Copepoda (33.33%), and 6 species of Cladocera (20%) were identified. It was found that the widely distributed species Rotaria neptunia (in 7 wells), Keratella quadrata (in 5 wells), Daphnia curvirostris (in 8 wells), Coronatella rectangula (in 6 wells), Chydorus sphaericus and Pleuroxus aduncus (in 5 wells each), Megacyclops viridis (in 8 wells) and Tropocyclops prasinus (in 6 wells). The most species (14 species) were found in well 8, followed by wells 3, 5, 7 and 9 with 11 species. In general, it was determined that there was a significant and positive relationship between zooplankton species diversity and abundance, and water quality parameters.
