This study is aimed to understand effective roles of ecological factors on nonmarine ostracods in Malatya province where 125 different aquatic bodies were randomly sampled during 3–10 August 2015. Totally, 24 of 25 species identified were new reports for the province while Cypridopsis lusatica was a new record for Turkey. The most common species Ilyocypris bradyi was collected from 12 different habitat types. Fifteen species based on their percent similarities among habitat types were clustered into five groups. The first two axes of Canonical Correspondence Analyses explained 66.1% relationship between species and environmental variables. Salinity, water temperature and chloride were found to be the most effective variables on species occurrence. Except chloride and oxidation–reduction potential, there was no significant difference in the mean numbers of environmental variables among the sampling sites with and without species (p  < .05). Five most abundant species portrayed the highest ecological tolerance ranges for water temperature. Heterocypris incongruens revealed the highest optimum and tolerance range for dissolved oxygen while Heterocypris salina showed maximum ranges for salinity. Increasing numbers of sampling sites did not increase the percent species numbers per site. Species distribution varied among the habitats. Accordingly, species with swimming ability tend to inhabit more stagnant water bodies while species without such ability were found in flowing waters. This implies that species with good dispersion modes may avoid negative effects of changes in ecological conditions. Thus, our results reveal that biotic factors can also be effective on species as much as abiotic ones.

生态因子对马拉蒂亚（土耳其）浅水区非海洋类捕食纲（甲壳纲）的有效作用

本研究旨在了解生态因素对马拉蒂亚省非海洋类兽类的有效作用，该省在2015年8月3日至10日随机取样了125种不同的水生生物。总共鉴定出25个物种中的24个是该省的新报告，而卢塞球藻是该省的新报告。土耳其的新纪录。最常见的物种缓殖蝇是从12种不同的栖息地类型中收集的。根据栖息地类型之间的相似性百分比，将十五种物种分为五类。典范对应分析的前两个轴解释了物种与环境变量之间的关系，占66.1％。发现盐度，水温和氯化物是影响物种发生的最有效变量。除了氯化物和氧化还原电位以外，有无样本的采样点之间环境变量的平均数没有显着差异（p  <.05）。五个最丰富的物种描绘出最高的水温生态容忍范围。Heterocypris incongruens显示出最高的溶解氧最佳和耐受范围杂藻盐沼显示出最大的盐度范围。采样点数量的增加并没有增加每个站点的物种百分比。物种分布因生境而异。因此，具有游泳能力的物种倾向于栖息在更停滞的水体中，而在流动的水中发现没有这种能力的物种。这意味着具有良好分散模式的物种可以避免生态条件变化的负面影响。因此，我们的研究结果表明，生物因子对非生物物种也同样有效。
