11. Earthworm and arbuscular mycorrhizal communities in agricultural soils : management of key soil organisms for sustainable agriculture
Sammanfattning : Intensive agriculture is detrimental to soil biodiversity and functioning. Promoting communities of key soil organisms, such as earthworms and arbuscular mycorrhizal (AM) fungi, may help improve agricultural sustainability by replacing inputs with ecosystem services. LÄS MER
12. Ecology of fungal denitrifiers in terrestrial ecosystems : global patterns and effects of management in agricultural soils
Sammanfattning : Denitrification is the dominant source of nitrous oxide (N2O) from terrestrial ecosystems, a potent greenhouse gas and stratospheric ozone-depleting agent. Fungi can perform denitrification and terminate the process with N2O, making them a potentially important source of N2O. LÄS MER
13. Diversity of soil microbial communities: In the perspective of targeting functional genes
Sammanfattning : Abstract Intensive land use in agriculture can lead to higher loss of biodiversity in soils and subsequently carbon due to tillage and application of pesticides and fertilizers. The microbial communities are pivotal to ecosystem processes in soil such as nutrient cycling, soil formation and plant productivity and thus are affected by land use. LÄS MER
14. Soil microbial responses to mild winters and seasonal change
Sammanfattning : The aim with this thesis work was to study microorganisms response to milder winters, different seasons, and altered temperature. Winter warming treatments were established in a semi-natural temperate grassland, simulating mild winters for two years. LÄS MER
15. On the Ecology of Saprotrophic Fungi and Bacteria in Soil: Biotic and Abiotic Control of Growth Rates
Sammanfattning : Two groups of organisms dominate the decomposition in soil: fungi and bacteria. One of the most important parameters to optimise for any organism is its growth, and thus a direct way to study the effect of environmental factors on fungi and bacteria in soil is to measure their growth rate.
