Non-predatory specifi c mortality (NPSM) of dominant zooplankton species, Daphnia (longispina
group) and Cyclops vicinus, was estimated during 1997-2000 sampling seasons on the basis of a new
direct method: live/dead sorting and sediment trap measurements. Simultaneously measured ecological
factors, such as water temperature, pH, dissolved oxygen, biomass of cyanobacteria, diatoms, greens
and euglens, levels of polyunsaturated fatty acids of ω3 family, α-linolenic (ALA) and eicosapentaenoic
(EPA), were considered as possible causes of the mortality using multivariant canonical correlation
analysis. Toxicity was discarded on the basis of another set of study of the reservoir. As found, the best
predictor of Daphnia mortality was EPA level, negatively correlated with NPSM value. Nevertheless,
large part of variance of Daphnia mortality and practically all variance of Cyclops NPSM remain
unexplained and need future investigation.
Keywords: non-predatory mortality, Daphnia, Cyclops vicinus, ecological factors, canonical correlation
analysis.
Introduction
Dynamics of zooplankton populations are
known to be of great importance for overall
functioning of aquatic ecosystems. Abundance
of zooplankton evidently depends on two factors:
growth (somatic and generative) and mortality.
Meanwhile, data on mortality are very sparse
compare to that of growth due to methodical
problems (e.g., Polishchuk and Ghilarov, 1981).
Consumption by predators, fi sh (e.g., Luecke et
al., 1990; Hulsmann et al., 1999) and invertebrates
(e.g., Razlutskij, 1996; Wojtal et al., 1999) are
often the main cause of zooplankton mortality in
many locations and seasons. Nevertheless, nonpredatory
mortality also can play a determinant

role (Luecke et al., 1990; Boersma et al., 1996;
Mehner et al., 1998; Dubovskaya et al., 1999;
Hulsmann and Weiler, 2000; Hulsmann and
Voigt, 2002). In general, causes of non-predatory
mortality of zooplankton are believed to be
limiting physical and chemical factors, disease,
senescence (Velimirov, 1991) and also food
(edible phytoplankton) limitation (Luecke et al.,
1990; Boersma et al., 1996). However, particular
causes of variations of the non-predatory mortality
in diverse sites and periods are still unknown. Nonpredatory
mortality estimations were indirect and
included double error, connected with estimations
of birth rate and consumption by fi sh. Finding of
any quantitative correlation of such unreliable
