Among them, three species (Eucypris kerkyrensis, Cypridopsis elongata, Bradleystrandesia parva) were new records for the Ostracoda fauna of Turkey. Bisexual populations of three species (Ilyocypris inermis, Trajancypris serrata and Psychrodromus olivaceus) were repeatedly occurred from Anatolia. Spearman Rank Correlation analyses illustrated a significant correlation for the four most abundant species (Condona neglecta, Heterocypris salina, Eucypris lilljeborgi and Potamocypris villosa) with electrical conductivity while temperature did not show a significant effect on species occurrence. Five species (Pseudocandona albicans, Ilyocypris gibba, Heterocypris incongruens, Heterocypris rotundata and Eucypris virens) did not have any significant correlation to those variables used here, but correlation was significant between Potamocypris villosa and three variables (pH, electrical conductivity and salinity). According to Environmental Tolerance Index (ETI), most species with high ETI values were widespread species. Such species with high tolerance and widespread (or cosmopolitan) distribution were named as cosmoecious specieseninfo:eu-repo/semantics/closedAccessAnatoliafreshwatertaxonomyecologybiodiversityArticle10.4194/1303-2712-v14_1_0214111202-s2.0-84899143992Q3163885WOS:000336248500002Q4
