1. Bacterial and fungal growth in soil: The effect of temperature and substrate addition
Abstract : Bacteria and fungi are the main agents in decomposition of soil organic matter. Their activity is determined by the availability and quality of substrate, especially its content of carbon, but also nitrogen and phosphorus. Other environmental factors, which affect the activity of the microbial community in soil, are temperature, moisture and pH. READ MORE

2. Factors Affecting Rates of Change in Soil Bacterial Communities
Abstract : The soil bacterial community is under the constant influence of its environment. Changing any of the factors affecting the bacterial community will induce a selection pressure which, with time, will change the community. In this work the effect of changing the temperature or pH on the soil bacterial community was studied. READ MORE

3. Soil microbial responses to mild winters and seasonal change
Abstract : 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. READ MORE

4. Microbial temperature dependences in soil: The belowground feedback to climate change
Abstract : 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. READ MORE

5. Boreal Lake Sediments as Sources and Sinks of Carbon
Abstract : Inland waters process large amounts of organic carbon, contributing to CO2 and CH4 emissions, as well as storing organic carbon (OC) over geological timescales. Recently, it has been shown that the magnitude of these processes is of global significance. READ MORE
