About the research project

Comparative palaeoecological studies are a valuable source of long-term data on biodiversity responses to environmental change that can provide important insights into future climate change responses. Paleoecological studies of marine taxa have been challenging, however, with recent technological advances in sedimentary ancient DNA research (sedaDNA), such studies can now be realised. This project will utilise genetic sequence data extracted from sediment cores collected at various sites in the Southern Ocean. These sedaDNA datasets were generated using metagenomic shotgun and/or RNA based hybridisation-capture techniques, both methods are commonly used in ancient DNA research to capture very degraded and fragmented sequences. The project will focus on (1) developing bioinformatic approaches for analysing and validating vertebrate and microbial DNA from sedaDNA, and (2) reconstructing millennia-scale records of biodiversity presence at key sites in the Southern Ocean and placing these into context with palaeoclimatic records in order to identify key environmental drivers associated with shifts in biodiversity communities. This research will provide novel insight into the past effects of climate change on biodiversity in the Southern Ocean, and will result in advances in bioinformatic approaches for ancient DNA analyses.
