“…To identify the new species, the collection at Biology Department of Hacettepe University was examined as a comparative material, and the following references were used : Smirnov (1976) ; Margaritora (1985), Negrea (1983Negrea ( , 1987, Brooks (1959), Mordukhai-Boltovskoi & Chirkova (1973), Pennak (1978), Scourfield & Harding (1966), Giindiiz (1990), Paggi (1989Paggi ( , 1992, Leentvaar (1978), Lillgeborg (1900), and Fryer (1974) .…”

Radioactive studies of phytoplankton in the cooling reservoir of the Beloyarsk atomic power station

“…Due to the ability for quick reproduction and creation of big biomass, plankton organisms are very important for the energy and matter turnover in the water ecosystems and for the self-purification of ponds from chemical and radioactive pollution [4]. The data on accumulation of radionuclides and other pollutants in plankton are very few in the literature, evidently because of sampling difficulty and the dynamics of spatial-temporal quantitative characteristics of the plankton.…”
