Philip Wookey
Phil is a Professor of Ecosystem Science at The University of Stirling and is the lead scientist on the Prime-Time project. He has extensive experience in soil and ecosystem ecology at high and mid-latitudes, both in tundra ecosystems and forests. He has worked since 1991 on the potential effects of environmental change on the structure and function (specifically nutrient cycling, soil organic matter dynamics and trace gas exchanges) of terrestrial ecosystems in the Fennoscandian mountains, Svalbard, northern Iceland and the North Slope of Alaska. He chaired the International Tundra Experiment (ITEX) from 1996-2003, and currently chairs the IASC (International Arctic Science Committee) Terrestrial Working Group and the UK Arctic and Antarctic Partnership (UKAAP).

David Johnson
David is a Professor of soil microbial ecology at the University of Manchester. His research focuses on understanding biological interactions in the terrestrial environment, particularly among plants, soils, mycorrhizal fungi and herbivores. Much of this research concerns the role of biological interactions in the context of carbon and mineral nutrient cycling, and therefore his group uses isotopic tracers to quantify nutrient fluxes. A key research focus is on the ecology of symbiotic mycorrhizal fungi that inhabit the roots of most plants and are ideal models for testing ecological theory, and crucial in regulating biogeochemical cycling and plant fitness. His group's research is applied to tropical and temperate forests, peatlands, grasslands and agri-ecosystems. |
Jens-Arne Subke
Jens-Arne is an Associate Professor and ecosystem scientist at the University of Stirling interested in understanding the response of biogeochemical cycles in terrestrial ecosystems to changes in environmental conditions, whether these are a result of climatic change, human land use, or perturbations from pollution. Past projects have included the following themes: Environmental controls on biotic CO2 flux dynamics, plant-soil interactions at the boreal treeline, plant-soil interactions in the decomposition of soil carbon in the rhizosphere, use of stable isotopes in ecology and biotic and abiotic drivers of methane (CH4) fluxes in peatlands.

Iain Hartley
Iain Hartley is a Professor in Terrestrial Ecosystem Science at the University of Exeter. His research focuses on the responses of terrestrial ecosystems to global change. He has worked in a wide range of ecosystems, from Arctic tundra to tropical rainforests. In particular, his research interests include: 1) determining the effects of permafrost thaw on greenhouse gas emissions from high-latitude ecosystems; 2) investigating the extent to which tropical forest productivity is limited by nutrient availability versus atmospheric CO2 concentrations; 3) quantifying the effects of global warming on soil and ecosystem carbon storage. Iain's research has been funded by the Natural Environment Research Council (NERC) and the UK Department of Energy and Climate Change (DECC), and he sits on the scientific steering committee of the AmazonFACE project, which will be the first experiment to expose a mature rainforest canopy to elevated CO2. He also currently serves on the NERC Radiocarbon Facility steering committee. |
Karina Clemmensen
Karina is a researcher and senior Lecturer at the Swedish University of Agricultural Sciences in Uppsala (SLU), her overall research interest is to incorporate detailed knowledge of fungal communities and their functioning into an ecosystem framework - particularly in relation to carbon balance and environmental change in Arctic and Boreal biomes. For more information about Karina's current research projects and past publications, click here. Lorna Street Lorna is a NERC independent fellow based at the University of Edinburgh, and is working with PRIME-TIME as a project partner. Her research focus is on the interactions between carbon and nutrient cycling, using stable or radio-isotope based experiments in combination with process-based models. Her fellowship research topic "Plant nutrition as Earth System Science" addresses the interactions between soil carbon dynamics, plant nutrient uptake, and plant growth |
Björn Lindahl
Björn is a Professor at the Swedish University of Agricultural Sciences in Uppsala (SLU) where he heads a group, conducting research about fungal ecology in boreal forest ecosystems. They study the interplay between fungal communities and their environment; how community composition depends on environmental parameters and disturbances, but also how fungi affect their environment, primarily as degraders of organic matter. For more information about Björn's research can be found here. Mark Garnett
Mark is the deputy director of the NERC Radiocarbon Facility (RCF) in East Kilbride. His expertise is in application of radiocarbon analysis for establishing chronologies and investigating the terrestrial carbon cycle. As part of this he develops methods to recover samples of carbon dioxide for 14C analysis from different environments for understanding the source and rates of carbon cycling (e.g. soil respiration, deep peat CO2, evasion from surface waters, atmospheric CO2). He is also interested in radiocarbon analysis of methane, carbon cycling and accumulation in soils/peats ,applications of bomb-14C, e.g. to age the surface layers of peats and application of 14C analysis in soil meso-fauna studies. More information about Mark and the RCF can be found here. |
