Effects of pollution and watercourse type on trophic structure: the silverside Basilichthys microlepidotus and its food resources in the Maipo River basin as a model

Neotropical Ichthyology
Pollution in freshwater ecosystems degrades water quality and alters macroinvertebrate assemblages, affecting their value as a food resource. In agricultural basins such as Chile’s Maipo River, channelization is an additional disturbance.

Biometrics and life cycle of Physa acuta Draparnaud, 1805 (Gastropoda: Basommatophora: Physidae) under human impact

Folia Malacologica, 2016
Alterations in the shell dimensions of Physa acuta Draparnaud, 1805 were studied from May to September in a sinkhole pond with very hard water in Siemianowice-Bytków (Upper Silesia, Southern Poland). This Mediterranean species turned out to be well adapted to the climate of Southern Poland and resistant to industrial water pollution.
