1. Modelling animal populations
Abstract : This thesis consists of four papers, three papers about modelling animal populations and one paper about an area integral estimate for solutions of partial differential equations on non-smooth domains. The papers are: I. Å. Brännström, Single species population models from first principles. READ MORE

2. Ontogeny and Population Biology of a Sex-Limited Colour Polymorphism
Abstract : This study has involved investigation of number of populations of the damselfly Ischnura elegans over several years, looking at frequency changes over time, morphological differences between the sexes and the morphs, differences in growth rate and development time, differences in fecundity between the morphs, and genetic differentiation between populations. I. READ MORE

3. Quantitative Genetics and Genome Structure in a Wild Population: the Use of a Great Reed Warbler Pedigree
Abstract : Long-term studies of birds play an important role in the understanding of quantitative traits in natural populations. The relative ease by which individual birds can be monitored and caught in the wild enable us collect detailed information from individuals throughout their life time, sometimes from several generations in a population.

4. Population ecology and management of waders breeding on coastal meadows
Abstract : Many wader (Charadrii) populations are declining throughout in Europe, but the underlying causes are often poorly known and diverse. To fully grasp the reasons behind declines in vulnerable wader populations, it is crucial to understand the demography. READ MORE

5. Effects of size-dependent predation and competition on population and community dynamics
Abstract : Most animals grow substantially during their lifetime and change in competitive ability, predatory capacity and their susceptibility to predation as they grow. This thesis addresses the implications of this on regulation and dynamics within populations as well as between population interactions. READ MORE
