Research Overview
My palaeoecological research involves the analyses of peat bog deposits in order to understand the rate and nature of former environmental changes. My research into peat archive records has been used to: i/ understand long-term peatland carbon sequestration rates (driven by either climate change, long-term succession processes and/or human impacts) ii/ investigate climate change spanning the early Holocene (~11,700 years ago) to the present based upon a range of sub-fossil plant and microorganisms preserved in peat matrices iii/ guide the restoration and preservation of peatlands. A long-term perspective is important for the latter, as peat archive records can be used to show the antiquity and to understand the naturalness and resilience of peat bog ecosystems to a range of natural and anthropogenic drivers of environmental changes. All three of these research foci are highly dependent upon the generation of precise and accurate chronologies. Working with my international colleagues I have developed a series of age/depth modelling techniques to refine and improve this key technique.
I use plant macrofossil and testate amoebae analyses to reconstruct environmental changes and 14C and 210Pb age/depth modelling to generate precise and accurate chronologies (typically with decadal/centennial precision) spanning the very recent past to the early Holocene. I have investigated a wide number of peatlands in Europe, Canada, Argentina, Chile, The Falkland Islands and sub-Antarctic islands. Given this wide range of peatlands across the world, I enjoy extensive research collaboration with leading members of the international palaeoecological community.
Current Research
Falkland Island peatlands as a mirror to understand future European peatlands (funded by The Leverhulme Trust)
The aim of this research is to understand the relationship between long-term peatland carbon accumulation rates, burning disturbance, the types of former peat forming plants and climate change across the Falkland Islands.
Peatlands are valuable ecosystems which take up and store carbon, mitigating the effects of climate change by taking greenhouse gases out of the atmosphere. For millennia they have captured carbon dioxide (a greenhouse gas) from the atmosphere and locked it away as peat. One of the consequences of recent climate change and human disturbance is that peatlands are now becoming more fire prone due to drainage, higher summer temperatures and reduced precipitation, which creates a water deficit.
In order to understand how carbon accumulation in Northern Hemisphere peatlands may likely change in the future, it is useful to look at how carbon accumulation varies in modern day ‘extreme’ (‘dry’) peatlands located in the Falkland Islands.
If you're interested, here are some pictures of these fascinating islands.
