1. Biodiversity patterns and the processes regulating them along elevation gradients in the Swedish mountains
Abstract : Biodiversity describes the total variation of life and includes the taxonomic, genetic, and phenotypic differences among organisms. Variations of biodiversity in space and time may be driven by ecological, evolutionary, or neutral processes. READ MORE

2. Investigating and Enhancing Performance of Multiple Antenna Systems in Compact MIMO/Diversity Terminals
Abstract : Today, owners of small communicating device are interested in transmitting or receiving various multimedia data. By increasing the number of antennas at the transmitter and/or the receiver side of the wireless link, the diversity/Multiple-Input Multiple-Output (MIMO) techniques can increase wireless channel capacity without the need for additional power or spectrum in rich scattering environments.

3. The Effects of Mutation and Selection on the Rate and Pattern of Molecular Evolution in Birds
Abstract : By comparing sequence diversity and divergence on sex chromosomes one can study how the rate of evolution in affected by mutation and/or selection. The rate of mutation in male biased, meaning that relatively more mutations are created in the male germ line than in the female. READ MORE

4. Characterization of Terminal Antennas for Diversity and MIMO Systems by Theory, Simulations and Measurements in Reverberation Chamber
Abstract : This thesis is based on the work of designing and building a small reverberation chamber, and to use this chamber for characterization of antennas on mobile terminals such as phones. The characterization is done in terms of radiation efficiency, diversity gain and maximum available capacity. READ MORE

5. Diversity and Ecosystem Functioning : Redundancy and Resilience in Freshwater Bacterial Communities
Abstract : Bacteria are immensely diverse and hold key-positions in essentially all biogeochemical cycles. In freshwater ecosystems, bacteria degrade and mineralize organic compounds, linking the pool of dissolved organic matter to higher trophic levels. READ MORE
