Purpose The aims of the study were to evaluate the effect of combined sewer overflows (CSO) and storm water drains (SWD) on metal bioavailability in small urban streams in Prague and to evaluate levels of metals in water, sediment, and macroinvertebrates. The following working hypotheses were adopted: (a) sites dominantly affected by SWD are less p...

This article is focused on definition and identification of optimal ecological flow for macrozoobenthos communities in small urban creeks affected by urban drainage using the Physical HABitat Simulation (PHABSIM) system. It describes the process of determination of ecological flows, from field measurement to determined values. Results show that com...

Trace metals (TMs) are still a serious problem in urban streams because of their toxicity and continuing significant levels in the aquatic environment, especially in bed sediments. Concentrations of Cd, Cr, Cu, Ni, Pb and Zn were monitored in the sediments of several small streams in the Prague area. These streams differ in the main source of pollu...

This paper reviews various impacts of urbanization on rivers and streams, which lead to symptoms summarized by the general term "urban stream syndrome". Growing areas of impervious surfaces cause deterioration of water recipi- ents flowing through urban areas. The symptoms of deterioration usually include altered chemical parameters of water and se...

Larvae of the three important Central American malaria vectors, Anopheles albimanus, An. vestitipennis, and An. darlingi, are found in distinctly different habitats broadly defined by hydrology and aquatic vegetation, but little is known about the actual food quality and quantity of these habitats. Polyunsaturated fatty acids (PUFA) are of special...
