A 23,000-yr pollen record from Lake Euramoo, Wet Tropics of NE Queensland, Australia

A new extended pollen and charcoal record is presented from Lake Euramoo, Wet Tropics World Heritage rainforest of northeast Queensland, Australia. The 8.4-m sediment core taken from the center of Lake Euramoo incorporates a complete record of vegetation change and fire history spanning the period from 23,000 cal yr B.P. to present. The pollen record is divided into five significant zones; 23,0...

A late glacial to present diatom record from Lake Euramoo, wet tropics of Queensland, Australia

A new diatom record from Lake Euramoo on the Atherton Tableland, north Queensland, Australia is used to assess regional climate change and variability and their links to forcing at a local to global scale. The major factor driving diatom composition in the approximately fifteen thousand-year record appears to be regional moisture availability. Patterns of diatom preservation and other indicator...

Macrophytes as indicators of bioavailable Cd, Pb and Zn flow in the river Przemsza, Katowice Region

A 5 km stretch of the river Przemsza, in southern Poland, was investigated with the aim of finding out if a gradient of metal pollution was present along the river and to determine the bioavailable flow of Cd, Pb and Zn between water, sediment and submerged macrophytes. In situ experiments in pots as well as experiments in sealed jars were performed by using Potamogetonpectinatus and Myriophyll...
