Records of Aquatic Beetles (Helophoridae, Hydrophilidae, Hydrochidae, Dytiscidae) and Physico-Chemical Parameters in a Natural Lake (Artvin, Turkey)


Abstract: Some ecological requirements of aquatic Coleoptera species were studied in a natural lake. Water beetle samples, collected in 2007 from the National Park Sahara-Karagöl belonging to the families Helophoridae, Hydrophilidae, Hydrochidae, and Dytiscidae were identified and listed. Both physical (conductivity and temperature) and chemical (pH, dissolved oxygen, total dissolved solids, hardness, organic matter, chloride, phosphate, and some metal ions) parameters of the inhabited water were measured.

Keywords: Aquatic Coleoptera, ecology, lake, variety, physico-chemical parameters
