Abstract—Communities of benthic macroinvertebrates in drainless Lake Chany, the largest lake in Western
Siberia, have been analyzed to estimate the effects of basic abiotic ecological factors (hydrophysical and
hydrochemical parameters of water and the type of bottom ground) on their composition, structure, and
dynamics. It has been shown that the level of development of these communities depends mainly on the water
regime of the lake and also on the type of bottom ground, lake depth, and water mineral content.

Lake Chany (Novosibirsk oblast) has the largest
surface area among lakes of Western Siberia. It has
major significance for economy and nature conserva-
tion, being a unique object for analyzing the ecosystems
of large drainless lakes at different stages of salinization.
The water area of the lake is divided into several pools,
including the Tagano-Kazantsevskii, Yarkovskii, Chin-
yaikhinskii, Yarkul’, and Malye Chany pools (Fig. 1).
The Yudinskii pool was separated from the lake with a
dam in 1971 and has dried up (Savkin et al., 2005). The
lake is fed mainly by snowmelt, and its surface area
varies from 1708 to 2600 km
depending on seasonal
and annual fluctuations of water level. Its main tribu-
taries are the Kargat and Chulym rivers.
Water mineral content (total dissolved solids) var-
ies between the pools, but the concentrations of chlo-
ride and sodium ions remain constant. A characteristic
climatic feature in the south of Western Siberia is cyclic
alternation of dry and moist periods, with consequent
strong fluctuations of water level and surface area in
drainless lakes. In Lake Chany, the amplitude of water
level fluctuations is about 3 m. As a result, significant
changes take place in the hydrochemical and hydrobio-
logical regimes of the lake and, therefore, in the level of
development of benthic invertebrates and fish produc-
tivity (Pul’siruyushchee…, 1982; Ekologiya…, 1986).
Long series of observations are necessary for
revealing long-term trends in the dynamics of com-
munities. Among the lakes of Western Siberia, Lake
Chany has the longest history of hydrobiological
observations, which were initiated by hydrobiologists
from Tomsk University in the late 19th century. Since
then, they have been continued, with short intermis-
sions, by specialists of the Limnological Institute,
Institute of Systematics and Ecology of Animals,
Institute for Water and Environmental Problems,
Siberian Branch, Russian Academy of Sciences
(IWEP SB RAS), and Siberian Research and Design
Institute of Fisheries. The first data on the zoobenthos
of Lake Chany were obtained by Berezovskii (1927).
More detailed studies on the lake fauna began in 1955
(Petkevich, 1959). In the subsequent period, character-
istics of benthic communities were comprehensively
described in two collective monographs (Pul’siruyush-
chee…, 1982; Ekologiya…, 1986). A major contribution
to the study of zoobenthos in the lake has been made
in the past decades (Miseiko, 2003, 2004, 2006; Vizer
et al., 2004, 2012; Bezmaternykh, 2005; Vizer, 2006;
Bezmaternykh et al., 2008, 2011).
The purpose of this study was to evaluate and gen-
eralize the available data on the spatiotemporal struc-
ture of benthic macroinvertebrate communities in
MATERIAL AND METHODS
Studies on the communities of benthic macroinverte-
brates (body size >1 mm) were performed in the course
of complex limnological expeditions on July 14–17, 2001
(73 samples) and August 14–18, 2004 (56 samples).
The material was collected and processed by standard
hydrobiological methods (Rukovodstvo…, 1992). Sam-
ples for qualitative analysis were taken with a net or a
scraper; for quantitative analysis, with a Petersen
dredge (sampling area 0.025 m
) or a GR-91-000 TO
bar dredge (0.007 m
). Methods and conditions of
