To understand spatial and temporal continuing occurrence patterns and relationships of Cyprideis torosa to several physicochemical variables, monthly samples from seven stations were collected from Kocaçay Delta (Bursa, Turkey) between 2018 and 2019. Four ( C. torosa, Koencypris ornata, Candona lindneri, Candona meerfeldiana ) of 14 ostracod taxa a...

To investigate how habitat type influences species diversity and distribution of algae, 115 sampling sites across eight different habitats (stream, spring, lake, pool, wetland, ditch, trough, hot-spring) were randomly sampled from Ağrı province, Turkey. A total of 392 algal taxa (gamma diversity) were identified, of which 212 taxa (54.08%) belonged...

To gain a better understanding of the effect of reproductive modes and swimming ability on ostracod distribution, we visited 111 randomly selected aquatic sites in Kırşehir province. A total of 35 ostracods were newly reported for the area. The number of species with and without swimming setae was not statistically different, but numbers of sexual...

This study was carried out in Yalakdere, which is the most important stream in Yalova, Turkey, in order to determine biological water quality, by using macroinvertebrate-based metrics and a multimetric index that was developed. In addition, it was also aimed to investigate the effects of drought and highway construction on stream benthic macroinver...

Due to the global climate change, there are serious problems in domestic waters, especially in the rivers. In order to determine the current state of the rivers and to take measures if necessary, The ecological condition of the water masses needs to be calculated. Three basic quality elements (Hydromorphological, chemical and biological) are used i...

The relationship between ecological characteristic of freshwater ostracods and their habitatpreferences has been a critical issue for understanding of both current and past aquatic conditions. Toevaluate this idea, 121 water bodies with 11 different habitat types were randomly sampled in the province ofKütahya. Water quality measurements indicated...

Patterns of epilithic diatom species distribution in relation to environmental variables from 12 sampling sites on the main stream and some of its tributaries in the Nilüfer Stream Basin were determined using multivariate statistical techniques. The stream basin has been heavily influenced by anthropogenic effects. The upper part of the basin that...

In this study, we aimed to compare epiphytic diatom species diversity, which identified at two different periods (July 1998 - June 1999 and June 2014 - May 2015) at littoral zon of Lake Uluabat. 214 taxa were identified belonging to Bacillariophyta division during the study period of July 1998 to June 1999, while 86 taxa at June 2014 - May 2015. Co...

This study was carried out at three stations of Lake Uluabat between March 2006 and January 2007. Composition, density and spatio-temporal variations of phytoplankton of Lake Uluabat were investigated. During the study period, a total of 169 taxa were identified. 56 taxa belong to Bacillariophyta, 51 to Chlorophyta, 25 to Cyanobacteria, 19 to Eugle...

Özet Uluabat gölü biyolojik çeşitlilik açısından ülkemizin en önemli sulak alanlarından birisidir. Ülkemizdeki on dört RAMSAR alanından biri olan Uluabat gölü, zengin kuş çeşitliliğine, flora ve faunaya sahip olması nedeni ile 1998 yılında Dokuz RAMSAR kriterinin 4’ünü sağladığı için RAMSAR alanı ilan edilmiştir. Ancak gölün tüm biyolojik çeşitlili...

We sampled Lake Çubuk, a shallow lake in Bolu (Turkey), for 26 months to investigate the effect of limnoecological changes on the composition of ostracod species. Seventeen ostracod species were identified from the six stations sampled between 2008 and 2010. Numbers of species and individuals were both significantly reduced during 2010, which corre...

A study of the diversity and distribution of epiphytic lichens were compared along an altitudinal gradient (900–1400 m) in the Fagetum zone of Uludag Mountain. Twenty four species of epiphytic lichens were analyzed. The most frequent species were Lecanora argentata, Lecanora carpinea, Lecanora chlarotera, Lecanora intumescens, Lecidella elaeochroma...

The new mayfly species Prosopistoma orhanelicum sp. n. (Ephemeroptera: Prosopistomatidae) was collected from Orhaneli stream, northwestern Anatolia, Turkey. The main diagnostic larval characters are described and compared with two species which are found in nearby geographic regions. The larvae of P. orhanelicum sp. n. are differentiated by the num...

In the present study, changes in glutathione S-transferase (GST) enzyme activity were investigated in Ulva rigida specimens, collected from four different depths at six sites in the southern region of the Sea of Marmara. GST enzyme activity showed significant increases and decreases at some sites according to depth. Different abiotic factors affect...

Three hundred and thirty-one phytoplankton taxa were identified from Lake Uluabat over a 12-month period in 1998–1999. Phytoplankton richness varied between 35 and 79 taxa, and the Shannon-Wiener diversity index range was 1.574–3.151. Lake Uluabat was characterized by a high variety of Bacillariophyta (152 taxa), Chlorophyta (89 taxa), and Cyanobac...
