Aulodrilus pigueti Kowalewski, 1914 (Annelida: Clitellata) – a new record for the Polish fauna from the Oder River and remarks on other oligochaetes rarely noticed in Poland
Abstract The cosmopolitan freshwater oligochaete Aulodrilus pigueti Kowalewski, 1914 (Naididae: Tubificinae) was recorded for the first time in Poland. The species was found at a few groyne fieldExpand
Molluscs of the middle and lower Odra: the role of the river in the expansion of alien species in Poland
The malacofauna of the middle and lower Odra (Oder River), a large river degraded by human activities, is still rich and diversified, with as many as 14.5% of the recorded species being alien to the Polish fauna. Expand
Ostracod Assemblages in Relation to Littoral Plant Communities of a Shallow Lake (Lake Świdwie, Poland)
The development of water vegetation during the vegetation season was conducive to growth in ostracod density, and the accessibility of mud in plant habitats had a favourable effect on the general density of ostracods. Expand
First record and DNA barcodes of the aquarium shrimp, Neocaridina davidi, in Central Europe from thermally polluted River Oder canal, Poland
The findings spanning more than a decade suggest that N. davidi may have established a self-reproducing population at this site, the second finding of the species in fresh waters of Europe and the first discovery of that species both in Poland and in Central Europe. Expand
A thermocline as an obstacle to the spread of water mites (Acari: Hydrachnidia) across the lake profile
A strong negative correlation was observed between the drop in temperature in the thermocline and the abundance and number of water mite species living beneath the thermOCline, and lower layers of the lake were increasingly penetrated by water mites as the temperatures above and below the thermokline were becoming more uniform.

The dynamics of seasonal ostracod density in groyne fields of the Oder River (Poland)
The dynamics of occurrence of certain species observed in the present study contradicted data from literature related to the following species; all obtained models of density dynamics pointed out maximum density in spring, indicating that during that period the conditions in the river were optimal for ostracod development, as confirmed by the results of studying environmental factors.

Co-occurrence of Sinanodonta woodiana with native Unionidae in the lower Oder
Monitoring of S. woodiana in Poland confirmed that the species spreads easily by colonizing waters of various types, which in the future may lead to the formation of large populations. Expand
Groynes: a factor modifying the occurrence of dragonfly larvae (Odonata) on a large lowland river
The presence of groynes provides the key to the restoration or stabilisation of the populations of certain species and to renaturalisation processes, achieving values approaching those obtained from modelled unregulated rivers. Expand
The Effect of Dredging of a Small Lowland River on Aquatic Heteroptera
It was shown that detritus and the effects of dredging were crucial to the distribution patterns of heteropteran species in this river, and dredging increased the number of available habitats. Expand
Regeneration of the molluscan fauna of a small lowland river after dredging
Dredging of the river to remove macrophytic vegetation and bottom sediment is a common anthropogenic disturbance in the river ecosystem that directly and indirectly influences benthic invertebrates,Expand
