This project is one of a number that are in competition for funding from the NERC GW4+ Doctoral Training Partnership (GW4+ DTP). The GW4+ DTP consists of the GW4 Alliance of research-intensive universities: the University of Bath, University of Bristol, Cardiff University and the University of Exeter plus five unique and prestigious Research Organisation partners: British Antarctic Survey, British Geological Survey, Centre for Ecology & Hydrology, the Natural History Museum and Plymouth Marine Laboratory. The partnership aims to provide a broad training in the Earth, Environmental and Life sciences, designed to train tomorrow’s leaders in scientific research, business, technology and policy-making. For further details about the programme please see http://nercgw4plus.ac.uk/
For eligible successful applicants, the studentships comprises:
- A stipend for 3.5 years (currently £15,009 p.a. for 2019/20) in line with UK Research and Innovation rates
- Payment of university tuition fees;
- A research budget of £11,000 for an international conference, lab, field and research expenses;
- A training budget of £3,250 for specialist training courses and expenses.
- Travel and accommodation is covered for all compulsory DTP cohort events
- No course fees for courses run by the DTP
We are currently advertising projects for a total of 10 studentships at the University of Exeter
Tropical ecosystems have undergone long-term changes that have modified biodiversity, carbon (C) storage, and ecosystem services (Navarrete et al. 2016, Hooghiemstra 1984, González-Carranza et al. 2012, Armenteras et al. 2013). In tropical Andean forests, long-term land-use has led to the major loss of forest, forming a vegetation mosaic converted for agriculture and later abandoned (Baptiste et al. 2017). While Andean forests are currently highly modified, there is little information about how changes have progressed and the drivers of change, e.g., climate, fire, historical contemporary human alteration of the landscape. This proposal seeks to identify ecosystem resilience to climate change and degradation in the Andes and to delineate ecological baselines. The PhD research project will help to address this major knowledge gap by working in tropical Andean montane forests.
Project Aims and Methods
This project will examine the ecosystem services and long-term resilience of Andean tropical forest ecosystems to environmental and climatic changes and improve understanding of the future implications of forest degradation for society. The work focuses on forests that are not pristine in that they are used by local communities and are affected by logging and fire. This fills a research gap in understanding how forests, which may be regarded as biologically ’degraded’, have undergone changes in biodiversity, in ecosystem services, and in how they participate in local and global cycles of carbon and energy. The project will achieve this through data collect contributing to the development of a network of permanent ecological monitoring plots. The research spans gradients in tropical Andean forests—with a focus on Colombia—of forest environment and degradation to allow evaluation of biodiversity and measurement of processes such as current and historical effects of fire, and carbon storage and changing climate. These data will be integrated with socio-cultural research, focusing on existing cultures of biodiversity conservation.
Methods: The PhD will involve a combination of field data collection and analysis of large vegetation and soil datasets. The field-based component will focus on forest structure measurements, fire evaluation, and collection of soil and charcoal in Amazonian forests. The analysis component will use the field and lab data to statistically evaluate the interaction between fire, climate, and forests to advance understanding of forest resilience. The student will also work with experts in ecosystem services, remote sensing, and palaeoecologists to study historical vegetation changes and with human geographers to improve understanding of socio-ecological systems. The student must be numerically competent and have a desire to work with large datasets and under challenging field conditions. This PhD provides the opportunity to work in a world-class research team on a genuinely novel research question and also ample opportunity to develop your own research interests. The results will have significant impacts in predicting tropical forest resilience, understanding long-term fire effects, redirecting conservation efforts, evaluating ecosystem services, and affecting policy such as Reducing Emissions from Deforestation and Degradation (REDD+).
