DETERMINATION OF CHANGES IN THE ZOOPLANKTON FAUNA OF SABUN STREAM (DÜZİÇİ/OSMANİYE) DURING THE FALL AND WINTER SEASONS

Ahmet Bozkurt1 , Rüstem Soydur2

In this study, the zooplankton fauna of the Sabun Stream, located within the boundaries of Düziçi District in Osmaniye Province, was investigated through weekly sampling during the autumn and winter periods from October 2025 to January 2026. A total of 47 zooplankton species were identified, the vast majority belonging to the Rotifera group. Among the Rotifera, the families Notommatidae, Lecanidae and Lepadellidae were particularly prominent in terms of species diversity. Certain species from the genera Cephalodella, Lecane, Colurella, and Lepadella were consistently present throughout all sampling periods. In contrast, species such as Leydigia leydigi, Alona guttata, Eucyclops speratus, Paracyclops fimbriatus, and Phyllognathopus viguieri were observed in only a limited number of sampling periods and were classified as rare components. Significant fluctuations in the weekly distribution of the zooplankton community were observed. Total abundance values were largely determined by the dominance of rotifers. The highest zooplankton density was recorded in November. The number of species varied depending on the sampling time, reaching maximum levels at the end of December and the beginning of January. Examination of species abundance values showed that certain rotifer species played a decisive role in shaping the community structure by reaching high individual numbers. The study found that water temperature varied over time and that this variation affected zooplankton distribution. No significant difference was observed between stations in terms of species diversity and abundance. Therefore, the assessments were generally considered together.
