“…This approach is actually the opposite one to "Sampling Effect Hypothesis" (Hıll et al 1994). Similar results were also reported previously (e.g., see Külköylüoğlu (2004), Nagorskaya & Keyser (2005), Pıerı et al (2009), Akdemİr & Külköylüoğlu (2011), Yavuzatmaca et al (2015) and Yavuzatmaca et al (2017)). On the other hand, Külköylüoğlu et al (2016) emphasized the significant relationships (p < 0.01) between the frequency of occurrence and number of sampled sites in some elevational ranges.…”

In order to determine the distribution of ostracods species between sea level and 1133 m a.s.l. in the Sakarya Province of Turkey, 83 different aquatic sites were randomly sampled during 9-12 May, 2014. This sampling yielded a total of 9598 individuals belonging to 33 taxa (31 living). The species Vestalenula cuneata and Kovalevskiella phreaticola were new reports for Turkey. The number of species with males (19) and without males (12) tends to decrease with increasing elevation while there is no significant difference in the number of species per site. This corresponds to a decrease in the numbers of species with (14) and without (17) natatory setae on second antennae (A2). Accordingly, presence of species with/ without natatory setae on A2, with different reproductive modes, and numbers of species changed along with elevation seem to be all mutually independent in the population sampled. The first two axes of Canonical Correspondence Analysis explained 74.4% of relationships between species and environmental variables. Furthermore, two well-known cosmopolitan species (Heterocypris incongruens and Ilyocypris bradyi) were observed in almost all of the elevational ranges. Overall, these results support the prediction that elevation seems to have no direct influence on the presence of species with or without swimming setae in sexual or parthenogenetic populations. Results suggest that unlike non-cosmopolitan ostracods, species with cosmopolitan characteristics may not be limited by elevation.

“…As previously stated (e.g., KÜlkÖylÜoğlu et al 2012c, Yavuzatmaca et al 2017a, the high species diversity was reported in the mid-elevational interval in the present study (Table 2). Whereas the finding of high diversity at low (e.g., Pèrez et al 2015 and high (e.g., KÜlkÖylÜoğlu et al 2012aKÜlkÖylÜoğlu et al , 2016 elevational intervals are also available in the literature. The difference between the present study and previous ones is the difference in the elevation ranges used.…”

Total of 26, 22 and 32 sites in Konya, Antalya and West Mediterranean basins in Turkey, respectively, were sampled twice during 2017 to compare the non-marine ostracod diversity. A total of 1787 individuals belonging to 31 species were recorded from all basins. Of which, nine species are common among basins when Fabaeformiscandona fragilis is new for Turkey. High species diversity was found at middle elevational intervals. The highest and lowest Shannon diversity index values were recorded for both Konya (H = 2.19) and Antalya (H = 1.90) basins, respectively. The highest beta diversities values are encountered between closed the Konya and other open basins. Species and environmental variables composition among basins and elevational intervals showed significant differences (p < 0.05, ANOSIM). Of species, cosmopolitans (e.g., Candona neglecta, Ilyocypris bradyi, Psychrodromus olivaceus) provide an important contribution to the differences in diversities among basins and elevational intervals. According to Canonical Correspondence Analysis, elevation appeared to be the common influential variables in all basins. Results suggest that alpha diversity is under the control of local and regional factors when beta diversity is primarily affected by regional factor. Although cosmopolitan species are positive indicators, they seem to make a significant contribution to alpha and beta diversities of ostracods.

“…Moreover, there is no any studies dealing the number or quality of eggs of species in low and high DO concentration and so the proposal of Ranta (1979) may be acceptable until otherwise stated. In addition, minimum and maximum values of ambient air temperature (12-40.20 ºC) (Horne 2007; the current study), calcium (5.25-80.80 mg/L) (Higuti et al 2009a;Pérez et al 2015) and magnesium (2.30-100.80 mg/L) (Holmes 1997;Pérez et al 2015) contents of water bodies where species collected.…”

In order to determine distribution, habitat and ecological preferences of Darwinula stevensoni, data gathered from 102 samples collected in Turkey between 2000 and 2017 was evaluated. A total of 1786 individuals of D. stevensoni were reported from eight different aquatic habitats in 14 provinces in six of seven geographical regions of Turkey. Although there are plenty of samples from Central Anatolia Region, recent form of the species was not encountered. Unlike recent, fossil forms of species were encountered in all geographic regions except Southeastern Anatolia. The oldest fossil record in Turkey was reported from the Miocene period (ca 23 mya). Species occurred in all climatic seasons in Turkey. D. stevensoni showed high optimum and tolerance levels to different ecological variables. Results showed a positive and negative significant correlations of the species with pH (P<0.05) and elevation (P<0.01), respectively. It seems that the ecological preferences of the species are much wider than previously known. Our results suggest that if D. stevensoni is used to estimate past and present environmental conditions, attention and care should be paid on its ecology and distribution.
