Description :
This study uses a palaeoecological approach to identify biological and sediment changes in Lake McKenzie, Fraser Island, Australia. A sediment core was extracted from the lake and the fossil diatom assemblage and sediment particle size analysed. Inferred environmental changes were detected throughout the core that pre-date European impacts. The likely causes of these changes are climatic oscillations. Further dating is required to establish a detailed chronological record and identify the timing of detected environmental change at Lake McKenzie.
