Research expertise

Nick is an ecologist and biogeochemist interested in global change effects of land use, climate change and atmospheric deposition on biodiversity and other ecosystem services. He also has a history of work on plant-soil interactions and their influence on carbon and nitrogen cycles in peatlands and grasslands in the UK and around the world.  He is a Professor at Lancaster University.

 

Supplying food, fibre, energy and water to an increasing human population whilst protecting biodiversity and natural resources in a changing world is one of the greatest challenges facing our generation

 

Selected projects

Plant functional diversity and peatland carbon cycling (NERC 2008-2011)

Peatlands represent a vast store of terrestrial carbon. We are exploring how changes in vegetation composition and diversity resulting from long-term management influence the cycling of C in peatland ecosystems. The study is carried out at Moor House National Nature Reserve an Environmental Change Network site in the Pennine hills of northern England.

Do Arctic plant-soil communities acclimate to long-term elevated CO2 exposure? (NERC 2011-2014)

Arctic ecosystems are of critical importance to global conservation and store up to one-third of global soil carbon reserves. Their stability under future atmospheric CO2 scenarios will have major influences on global biodiversity and warming. This work is a collaboration with Dr Dylan Gwyn Jones and Dr John Scullion (Aberystwyth University).

Linkages between plant functional diversity, soil biological communities and ecosystem services in agricultural grassland (BBSRC 2011-2016)

The issue of soil carbon storage is high on the political and scientific agenda, largely due to growing interest in the extent to which soils can sequester carbon. This study is testing whether grassland "plant community traits" can be managed to promote sequestration of carbon in soils, as a result of altering the amount and quality of carbon inputs to soil and their processing by the microbial community. Work involves establishment of long-term large-scale field experiments that will provide the first information on the potential for plant diversity to be utilised to manipulate soil nutrient cycling towards greater carbon and nitrogen storage, and lower greenhouse gas emissions.  

The project is joint collaboration between Dr Nick Ostle and Prof Richard Bardgett (Lancaster University), and Prof Liz Baggs (Aberdeen University).

Respiration in the Andes: climate sensitivity of soil respiration (NERC 2010-2013)

View of Trocha Union-San Pedro

The eastern flank of the Tropical Andes is the most biologically diverse region of the planet. This region is likely to warm by 3-5 ºC this century with likely consequences for ecosystem processes and biological diversity. The climatic vulnerability of the exceptionally large soil carbon stores in the region is very poorly documented and, as argued by the IPCC (Intergovernmental Panel on Climate Change), understanding is urgently needed.
