16. Modeling lichen performance in relation to climate : scaling from thalli to landscapes
Sammanfattning : Lichens can colonize nearly all terrestrial habitats on earth and are functionally important in many ecosystems. Being poikilohydric, their active growth periods are restricted to periods when the thallus is hydrated from atmospheric water sources, such as rain, fog and high relative humidity. LÄS MER
17. 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
18. A study of ethylene production via the 2-oxoglutarate dependent pathway in S. cerevisiae
Sammanfattning : The detrimental effect of the petroleum industry on the environment combined with the threat of peak oil has driven the exploration for alternative strategies to produce traditional petrochemicals. Biotechnological production could be an alternative, using microorganisms to convert renewable feedstocks into desired products. LÄS MER
19. Microbial temperature dependences in soil: The belowground feedback to climate change
Sammanfattning : Since the Industrial Revolution, human activities have elevated atmospheric CO² concentrations. The consequences of this include rising temperatures, shifts in precipitation patterns, and increased intensity and frequency of extreme weather events, such as heat waves and droughts. LÄS MER
20. Soil salinity as a driver of microbial community structure and functioning
Sammanfattning : Soil salinization is a pressing agricultural problem in many areas of the world, particularly in areas heavily reliant on irrigation agriculture. While the negative effects of salinity on crop plants have been widely studied, its effects on soil microorganisms have received less attention, and the impact of soil salinity on both microbial community structure and functioning is not well understood.
