“…Inasmuch as elevation indicated a strong negative correlation with water temperature (P < 0.01) when water temperature exhibited positively significant correlations with other variables (e.g., pH, electrical conductivity) ( Figure 2). Like the present study, studies previously done in and near the border of the present study's area (Çankırı (Külköylüoğlu et al, 2016), Kırşehir (Külköylüoğlu et al, 2019), Artvin (Külköylüoğlu et al, 2020), Giresun (Çapraz et al, 2020 under review)) also declared the importance of elevation on the distribution of ostracods except studies done in Erzincan (Akdemir and Külköylüoğlu, 2014), Ordu (Külköylüoğlu et al, 2012a), Kahramanmaraş (Külköylüoğlu et al, 2012c) and in Sinop (Yavuzatmaca et al, 2017). Elevation was also reported as an important variable that plays a role in the composition of ostracods in Friuli Venezia Giulia (NE Italy) (Pieri et al, 2009), Western Mongolia (Van der Meeren et al, 2010) and in Kenya (Rumes et al, 2016).…”

To compare species compositions of ostracods, streams and lakes were sampled in spring, summer, and autumn seasons of 2018. A total of 26 ostracod species were found in lakes (18 spp.) and streams (12 spp.). Shannon index (H') and evenness values of streams were higher than lakes in all seasons. Highest H' values were reported in the autumn season for all combined (lakes + streams) and lakes data, while in spring for streams. According to the beta-diversity (β) index values, variability of ostracod species composition in lakes were higher than streams, and its value was highest in spring (0.40) when and lowest in summer (0.34) among seasons for combined data. Pairwise comparison of spring and autumn displayed higher β-diversity values than other comparisons, while its value was 0.41 between lakes and streams. According to Canonical Correspondence Analysis results, elevation showed significant (P = 0.006) effect on distribution of species. All results suggested the importance of seasonality to evaluate the biodiversity of a region rather than the number of sampling sites, and the autumn season seems to be more diverse than others in terms of species diversity.

“…This corresponds with the previously known range (605-1954 m a.s.l.) (Ku¨lko¨ylu¨og˘lu et al, 2012c;Akdemir and Ku¨lko¨ylu¨og˘lu, 2014). Such correlations revealed by the results of CCA partially correspond to the optimum and tolerance values of individual species (Table 4).…”

-To understand the distribution and ecological characteristics of non-marine ostracods, the Poisson Method was applied to a total of 41 taxa (26 recent and 15 sub-fossil) from 111 (out of 120) aquatic bodies of Adyaman Province, Turkey. All taxa were new records for the area and Schellencandona insueta and Gomphocythere n. sp. were the first records for Turkey. According to the Poisson method, ostracods were randomly distributed among all sampling sites (P > 0.05). This is especially true for the cosmopolitan species (Candona neglecta, Heterocypris incongruens, Ilyocypris bradyi and Psychrodromus olivaceus) with broader ecological tolerance ranges to different environmental variables. According to canonical correspondence analysis (CCA), the first two axes explained 77.4% of the relationships and the most effective variables were found as electrical conductivity (F = 3.987, P = 0.002, l = 0.31), water temperature (F = 3.582, P = 0.002, l = 0.17), pH (F = 3.510, P = 0.002, l = 0.12) and elevation (F = 4.491, P = 0.02, l = 0.37). Additionally, the ratio (numbers of taxa/site = 2) was found same at lower (450-550 m) and higher (1359-1459 m) ranges, in which H. incongruens and I. bradyi were the most common species found from different habitats. Overall, random distribution of ostracods among sampling sites seemed to be more affected by random distribution of cosmopolitan species at the regional level than the non-cosmopolitans whose distribution may be uniform or clumped since they prefer certain types of ecological conditions at local level.

“…The species located closer to the center of the CCA diagram ( Figure 2) are also those with wide tolerance and wide distributional ranges, while species with rare occurrences are scattered on the diagram. Although it is not certain, similar ecological characteristics of the species may be one of the reasons for their occurrence around the center (Yılmaz and Külköylüoğlu, 2006;Akdemir and Külköylüoğlu, 2014). According to CCA results (Table 4), water temperature and electrical conductivity (including salinity) were the two most influential factors on species.…”

In order to compare the ostracod species composition of the Zonguldak and Bartın regions of Turkey, samples were collected from 105 aquatic sites with 7 different habitats during June 2013. Thirteen and 18 species were identified from Bartın and Zonguldak, respectively. While all of the species are new reports for Bartın, 11 species are new for Zonguldak. Twenty-two species were common in both regions, with 40.9% similarities. Species abundance (49.2 individuals/site) was found to be greater in Zonguldak than in Bartın (33 individuals/site), but the number of species per sampling site was higher in Bartın (0.48 spp./site) than in Zonguldak (0.42 spp./site). Increasing the numbers of sampling sites did not increase the numbers of species. Among the habitat types, the numbers of species per site was the lowest in troughs (0.35 spp./site). Canonical correspondence analyses explained 78.3% of the correlation with relatively low variance (9.8%) between the 15 most common species and 4 environmental variables in the regions, where water temperature (F = 3.216; P = 0.002) and electrical conductivity (F = 2.525; P = 0.018) displayed strong correlation with the species. However, water temperature per se did not show a significant effect on the numbers of species (P > 0.05). Cosmopolitan species showed relatively high tolerance and optimum values to different environmental variables.
