Saprobiological analysis holds a prominent placeamong methods of biological analysis of fresh waters.To estimate the degree of organic water pollution, spe�cialists widely use Pantle–Buck’s (1955) saprobityindex modified by Slade ek (1973), which takes intoaccount the relative occurrence frequency of hydro�bionts (h) and their indicator significance (s). To dis�tinguish the roles of individual species in indicating thedegree of water pollution, Zelinka and Marvan (1961)introduced the scale of their indicator weights (J). As arule, the indicator significance and indicator weight ofa given zooplanktonic organism are determined frompublished tables (Unifitsirovannye metody…, 1977;Makrushin, 1974a, 1974b). However, the possibility ofusing this method on a wide scale is limited becausethe above parameters may vary between differentregions (Rukovodstvo…, 1992). Thus, significant dif�ferences between the faunas of central European andWestern Siberian water bodies may be responsible fordifficulties in using the table values of s and J. The pur�pose of this study was to calculate the indices of indi�cator significance of zooplanktonic organisms forwater bodies of southern Western Siberia.

Calculations were made on the basis of data on132 lakes in Novosibirsk and Altai regions, 10 transects inthe Novosibirsk reservoir, and several small rivers inthe south of Western Siberia, which were collectedbetween 1990 and 2010. The results of processing1236 zooplankton samples were included in analysis,and water bodies with a total water mineralization(TDS) of no more than 1.0 g/dm3 were selected forcalculating the indices of interest.

Samples for hydrochemical analysis were takensimultaneously with hydrobiological samples, at thesame sites, to be assayed for BOD5, COD, dissolveoxygen, pH, and the contents of ammonium, nitrite,nitrate, and phosphate ions (GOST…, 1977). On thebasis of these hydrochemical parameters, the class ofwater quality was estimated on a six�grade scale(Oksiyuk et al., 1993), and each class was assigned to a

c

ˆ

certain category of water saprobity according to thevalue of the Pantle–Buck index (S).

Indices of saprobic valence of zooplanktonicorganisms were calculated by the equation proposedby Shitikov et al. (2003) for benthic organisms. Thisequation takes into account the proportions (relativeabundance) of species, rather than simply the fact oftheir presence or absence, which improves the sensi�tivity of the calculated saprobity index.

The sample formed as described above was used tocalculate the values of aik, the saprobic valence of spe�cies i in class k. The saprobic valence of a speciesaccording to Zelinka and Marvan (1961) indicates towhat extent it is characteristic of waters with a certainlevel of saprobity. In the simplest case, this parametermay be considered proportional to the relative abun�dance of species i in samples from biotopes of class k:

where L is the number of water quality classes (in ourcase, L = 6), and mk is the number of measurement ofkth type. The resultant matrix with dimensionality 6n(with n being the total number of species per sample)makes it possible to estimate the role of each speciesand its occurrence frequency in a water body of certaintype. The sum of valences calculated for each speciesin all six zones of water saprobity is 10 grades. We tookxik to be equal to the proportion (%) of individuals ofthe ith species from the total number of organisms inthe sample. If the number of individuals (N) was usedinstead of the proportion (xik = Nik), the equationacquired the form proposed by Tsimdin’ (1979). In ourcase, such a form of the equation was not suitable,because water objects included in the study markedlydiffered in quantitative parameters of zooplankton.

REGIONAL INDICES OF THE INDICATOR SIGNIFICANCE 531

Proceeding from the distribution of saprobicvalences in the above zones, we then calculated thevalues of indicator significance s and indicator weight J(Tsimdin’, 1979) for 111 species and forms of zoop�lanktonic organisms (table).

Comparison of these indices with those from thetables for European water bodies showed that, in somespecies (e.g., Alonella nana, Keratella hiemalis, andCyclops strenuus), they not only differ in value but alsoindicate a different class of water quality. This leads toserious errors in calculated regional values of the Pan�tle–Buck index, which may widely vary depending onthe species composition of a given zooplankton ceno�sis and the proportion of indicator species in it. Inmost cases, the saprobity index for Western Siberianwater bodies proves to be overestimated.

Since water bodies included in analysis are practi�cally undisturbed, the calculated values of the indices(table) can be regarded as background values.
