About the Project

Project Description:

Project Background

Tropical peatlands are the most carbon-dense ecosystems in the world and they store the equivalent of ~10 years of global fossil fuel emissions in their soils (Page et al., 2011). They also provide important ecosystem services to the people living near them. Despite their importance, crucial questions remain about how they may respond to environmental and climate changes (Sjögersten et al., 2014). Improving our understanding of these ecosystems is critical as they are at high risk from both climate change and land use change. Protection and improved management of tropical peatlands can also play an important role in meeting the greenhouse gas emissions targets set out under the Paris and Glasgow Agreements.

Project Aims and Method

The project aims to understand how past environmental and climatic drivers have affected peatland functioning in the past. This will inform how best to include peatlands in land-surface models and will allow us to better predict how the peatlands will respond to present and future climate change. Using samples collected in the Peruvian Amazon Basin (and complemented with cores from other tropical areas of the world), this PhD will investigate:

-         How has peatland hydrology affected carbon cycling during the Holocene?

-         How has peatland vegetation responded to climate changes in the past?

Answering these questions will involve querying the paleo-archive that is contained in peatlands. To this end, you will access to cores from different sites in Peru and across the tropics. The PhD will train you in paleo-methods, including macrofossil analysis and testate amoeba (Swindles et al., 2018). There is also the possibility of examining the distribution of hopane isotopes and plant biomarkers to learn more about precipitation and hydrology in these as yet unexplored ecosystems. There is considerable flexibility for you to pursue different research avenues dependent on their interests


This project will provide training in cutting-edge laboratory methods including biomarkers, testate amoeba, pollen, macrofossils and geochemistry. You will also be provided with training in field skills. You will be encouraged to participate in training courses to develop both technical and personal skills essential for a successful scientific career, including the opportunity to present your research at a major international conference. 

Award Provision:

The “Grupo GGF scholarship” has been generously donated by the Peruvian Grupo GGF company. This award provides annual funding to cover Home or International tuition fees and a tax-free stipend of at least £15,609 per year tax-free stipend.

International applicants need to be aware that you will have to cover the cost of your student visa, healthcare surcharge and other costs of moving to the UK to do a PhD.

Entry requirements

Applicants for this studentship must have obtained, or be about to obtain, a First or Upper Second Class UK Honours degree, or the equivalent qualifications gained outside the UK, in an appropriate area of science or technology such as Environmental Science, Soil Science, Geography, Chemistry, Biology, Ecology, etc. 

You must be enthusiastic to organise and undertake prolonged research trips to the Peruvian Amazon and other tropical peatland areas. You must also have, or demonstrate a strong capacity to learn a good to fluent level of Spanish and good analytical skills. Prior experience of laboratory work or/and field work in the tropics and the Amazonian forests would be advantageous. We welcome applications from prospective students coming from countries in the South American/Amazonian region.

If English is not your first language you will need to meet the required level (Profile B) as per our guidance at https://www.exeter.ac.uk/pg-research/apply/english/

How to apply

In the application process you will be asked to upload several documents. 

• CV

• Letter of application (outlining your academic interests, prior research experience and reasons for wishing to undertake the project).

• A Research proposal (3x A4 pages outlining your understanding of what the project will entail, including a short literature review)

• Transcript(s) giving full details of subjects studied and grades/marks obtained (this should be an interim transcript if you are still studying)

• Two references from referees familiar with your academic work. If your referees prefer, they can email the reference direct to [Email Address Removed] quoting the studentship reference number.

• If you are not a national of a majority English-speaking country you will need to submit evidence of your proficiency in English.

The closing date for applications is midnight on 14th August 2022. Interviews will be held virtually in the week commencing 22nd August 2022.
