Freeze-thaw effects on greenhouse gas emission, investigated by on-line concentration and isotope analyses
|Target group:||Biology, Biochemistry|
|Educational level:||Masters, Bachelor|
There is global concern that greenhouse gas emissions are affecting climate. Carbon dioxide and methane are the two most important greenhouse gases in terms of climate change; however, there are still uncertainties about their release from soils, and the effect of different plant species on emission rates.
|Methods used:||On-line CO2 and CH4 measurements of air in mini-ecosystems in growth chamber, using isotopes in ecology, relating to soil and plant cover|
|Keywords:||greenhouse gas emission, arctic and temperate ecosystems, influence of plant species, plant-microbe interactions, freeze-thaw and dry-rewet processes|
