1. Lake bathymetry as driver of salmonid population size structure and biomass
Sammanfattning : Most fish species undergo ontogenetic niche shifts from feeding on pelagic zooplankton, to larger benthic invertebrates and in some cases also to fish. These ontogenetic niche shifts have strong impact on the interactions within and between species, with effects on individual growth, population abundance and food web dynamics. LÄS MER
2. Ribosome and ribosomal RNA Structure : An experimental and computational analysis of expansion segments in eukaryotic ribosomal RNA
Sammanfattning : Ribosomes are large ribonucleoprotein complexes which incorporate amino acids into peptide chains during translational process in all types of living cells. The eukaryotic ribosome is larger compared to its prokaryotic counterpart. LÄS MER
3. Structure Determination and Prediction of Zeolites : A Combined Study by Electron Diffraction, Powder X-Ray Diffraction and Database Mining
Sammanfattning : Zeolites are crystalline microporous aluminosilicates with well-defined cavities or channels of molecular dimensions. They are widely used for applications such as gas adsorption, gas storage, ion exchange and catalysis. The size of the pore opening allows zeolites to be categorized into small, medium, large and extra-large pore zeolites. LÄS MER
4. Essays on Capital Structure
Sammanfattning : Chapter 2 analyses the relationship between capital structure and industry classification of Swedish firms. This study also analyses the determinants of the capital structure at the industry level. LÄS MER
5. Genetic structure and dispersal in plant populations
Sammanfattning : This thesis focuses on the spatial structure and methods to identify spatial structure in plants. Methods that investigate genetic structure can mainly be divided into equilibrium methods that reveal summed dispersal over many generations, and cluster methods, that reveal more recent dispersal events.
