Invertebrate secondary production, or the formation of invertebrate biomass through time,
has been estimated in many freshwater benthic habitats. It has been a major research theme …

A critical step in understanding food webs and trophic dynamics of communities is
quantification of the role of the primary consumers, and a major aspect of such quantification …

Littoral benthic macroinvertebrate communities in lake reservoirs often are exposed to
repeated fluctuations in water level, but little is known of the effects of drawdown on benthic …

This fish community survey conducted in the impounded Warta River at a backwater (AB)
and a tailwater (CD) sites is a continuation of our former study (1985–2002). Similarly as the …

The main goal of this preliminary study was to analyse the diet spectrum of racer goby (N.
gymnotrachelus), the most abundant gobiid invader in the Polish inland waters. That aspect …

The impact of a large lowland temperate zone reservoir on chironomid and fish biodiversity
was investigated in the same upstream (U) and downstream (D) sites on the same sampling …

The paper assesses the impact of the Jeziorsko dam reservoir on chironomid assemblages
and selected environmental factors in the Warta River, Poland, by means of patterns …

In March 1989 both banks of a 450 m section of the Warta River, 2 km above a reservoir,
were cleared of their riparian vegetation (osiers, willows and alders). In October 1988 17 fish …

An atypical development of submersed aquatic macrophytes (SAM, mainly Stuckenia and
Potamogeton) in the large lowland alluvial Warta River (Poland) occurred annually as an …

In an altered stretch of the lowland River Warta, central Poland, downstream of the Jeziorsko
Reservoir, patches of submersed aquatic macrophytes (SAM) are dependent on water …
