We can use sediments like an ecological time machine to address key questions relating to ecological and evolutionary responses to environmental change.

Sediments are the only way to obtain empirical information about ecological processes that occur on decadal/centennial tiemscales (e.g. tree generation times).

Potential projects include:

  • Tree population modelling across abrupt climate-change events
  • Developing new methods to improve species identification from sediments
  • Understanding how exposure to UV-B radiation influences speciation and extinction rates by studying past events in the fossil record
