Acta Zoologica Academiae Scientiarum Hungaricae, 67(4), 377-401.1217-8837http://dx.doi.org/10.17109/AZH.67.4.377.2021https://hdl.handle.net/20.500.12491/11043Ostracods are one of the most suitable organisms because of their ecological and morphological preferences for habitat types to study the diversity between streams and lakes. In this study, 24 streams and 16 lakes were sampled in 2019 to evaluate the species compositions between streams and lakes. Environmental heterogeneity in the sense of the physicochemical variables was found among the habitats. 24 of the 29 species with 923 individuals were found in the lakes when 13 species with 898 individuals were found in the streams. Eight species were common in both habitat types. Species contributing about 70.81% to the significant differences in the species composition between the habitats showed cosmopolitan characteristics. Species variation among the replicates of lakes was higher than streams. Results indicated that the species composition was probably associated to dissolved oxygen and electrical conductivity in lakes and streams, respectively. Overall, results suggested that the determination of influential local factors (e.g., dissolved oxygen, electrical conductivity) in different aquatic bodies can provide important contributions to the estimation of which habitat types can be chosen by species and the use of species as bioindicators.eninfo:eu-repo/semantics/openAccessElevational RangeLotic And LenticBenthonic And NektonicEnvironmental HeterogeneityCosmopolitan SpeciesOstracodaCrustaceaArticle10.17109/AZH.67.4.377.20216743774022-s2.0-85121248174Q3WOS:000721569700006Q3
