Abstract
In this study, it was aimed to
investigate of phytoplankton and phytobenthos in 19 rivers and Lake Eber
for the assessment of ecological quality in the Akarçay basin. A total
of 63 phytoplankton species were identified. Phytoplankton was evaluated
according to sensitive species and pollution indicators in rivers. Lake
Eber was determined as eutrophic and sensitive area according to
phytoplankton functional groups and Q Index. The presence of phytobenthic macroalgae
was detected only some sampling points in rivers. Therefore diatoms were used
as phytobenthos quality element. A total of 64 diatom species were
identified and diatom indices were calculated. Concerning the phytobenthos
assessment, IDP index ranged between 2 and 4, and ecological status
changed between medium and very bad.
