Boreas, EarlyView.Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Fish and macroinvertebrates in lowland drainage canals with and without grass carp
, 2006 Diploid grass carp (Ctenopharyngodon idella L.) were introduced to a lowland Waikato drainage canal at an initial density of 40-80 kg ha -1(83-167 fish ha -1) to control aquatic macrophytes and improve water flow.

Pethoxamid effects in non-target aquatic macrophytes
, 2021 As primary producers, macrophytes in water bodies represent irreplaceable part of aquatic environment. Negative effects of herbicides in non-target macrophytes, as well as their detection in surface waterbodies have been repeatedly found.

Bioaccumulation of nickel by aquatic macrophytes
Desalination and Water Treatment, 2010 Aquatic plants are being used successfully for the accumulation of trace elements in natural and constructed wetlands. Four aquatic plants were examined for their ability to remove heavy metals from contaminated water. In our study, bioaccumulation abilities of Lemna, Apium, Ceratophyllum and Groenlandia species were found.
