1. Changing population distribution in Sweden : long term trends and contemporary tendencies
Abstract : The aim of the thesis is to describe and analyse the population redistribution in Sweden at different geographical levels from the beginning of the 19th century to the end of the 20th century. The analysis is approached in three different ways. First, the redistribution at different geographical levels is analysed (papers I and II). READ MORE

2. The role of microclimate for the performance and distribution of forest plants
Abstract : Microclimatic gradients may have large influence on individual vital rates and population growth rates of species, and limit their distributions. Therefore, I focused on the influence of microclimate on individual performance and distribution of species. READ MORE

3. Finding fitness : empirical and theoretical explorations of inferring fitness effects from population-level SNP data
Abstract : The distribution of fitness effects (DFE) describes the likelihood that a new mutation has a specific effect on the fitness of an individual in a given population. The shape of the DFE is a result of several factors such as population size, mating system and selective environment, and can in turn influence the evolutionary potential of a species. READ MORE

4. Biofilms in Nitrogen Removal - Bacterial Population Dynamics and Spatial Distribution
Abstract : Efficient nitrogen removal at wastewater treatment plants (WWTPs) is necessary to avoid eutrophication of recipient waters. The most commonly used approach consists of aerobic nitrification and subsequent anaerobic denitrification resulting in the release of dinitrogen gas into the atmosphere. READ MORE

5. Ecology and genetic population structure of Indo-Pacific bottlenose dolphins in East Africa
Abstract : Many marine mammal populations are threatened by anthropogenic activities. The Indo-Pacific bottlenose dolphins (Tursiops aduncus) off Zanzibar are subject to high levels of bycatch, negative impact from tourism and were previously hunted. READ MORE
