Professor Yadvinder Malhi CBE FRS
Lead, Ecosystems Programme, ECI
Professor of Ecosystem Science, SoGE
Jackson Senior Research Fellow, Oriel College
The broad scope of Yadvinder’s research interests is the impact of global change processes such as atmospheric change and direct human modification on the ecology, structure and composition of terrestrial ecosystems, and in particular temperate and tropical forests. This research addresses fundamental questions about ecosystem function, diversity and dynamics, whilst at the same time providing outputs of direct relevance for conservation and adaptation to climate change. His group applies a range of techniques including field physiological studies, intensive and long-term ecological monitoring, quantitative and qualitative social science methodologies, satellite remote-sensing and GIS, ecosystem modelling, and micrometeorological techniques. He coordinates an extensive and expanding research programme in Asia, Africa and particularly across the Amazon and Andes region. He also runs an active research programme at Oxford University’s Wytham Woods research site. He was co-founder of the Amazon Forest Inventory Network (RAINFOR) which has resulted in over 50 publications. In recent years he has developed an international research network (GEM: gem.tropicalforests.ox.ac.uk) collecting data on ecosystem function in a number of research sites across the tropics.
Dr Jesús Aguirre Gutiérrez
Associate Professor, SoGE
Lead, Functional Biodiversity & Remote Sensing Lab, ECI
Jesus leads the Functional Biodiversity & Remote Sensing Lab within the Ecosystems Programme in the Environmental Change Institute. The goal of his research is to disentangle how a changing climate has impacted, is currently driving and will modify in the near future our natural forest ecosystems. Much is still unknown about how tropical forests around the world are responding to an increasingly fast changing climate, and there may be regions that are or will experience stronger biodiversity shifts and may be in more need of protection or regulation. Having grown-up in Guadalajara, one of the biggest cities in Mexico where not much nature is around, Jesus decided to spend a year living with the indigenous "Raramuri" community in Northern Mexico to learn from their vision of nature. His research interests come from understanding the importance nature has on our livelihoods - something he learnt through his experiences with indigenous communities in Mexico and abroad. He was previously and NERC Independent Research Fellow at the School of Geography and the Environment and the Environmental Change Institute, and has recently been promoted to Associate Professor. In his work he tries to understand the role that plant functional characteristics play in the resilience of tropical forests and make use of field assessment and also lots of remote sensing data from drones and satellites. Currently he is working across several countries including Mexico, Brazil, Peru, Ghana, Gabon, Malaysia and Australia.
Dr Nicola Stevens
Trapnell Fellow in African Environments, Linacre College
Biodiversity Cluster Coordinator, SoGE
Nikki’s research interests are centred around understanding vegetation dynamics in African savannas and how they are likely to change given increasing global change pressures like altered fire and herbivory regimes against a backdrop of changing CO2 concentrations. Along this vein I have become particularly interested in the phenomenon of woody encroachment where open ecosystems across the tropics are being invaded by native woody species. It has also driven me to improve our ability to predict future species ranges under global change by improving our mechanistic understanding of range edges in disturbance limited systems. She has ongoing projects in Southern Africa with the hopes to expand this research to other tropical savannas.
