1. Studies of declining populations - temporal genetic analyses of two arctic mammals
Abstract : Many populations and species are threatened with extinction today. Understanding the extinction process and the factors behind population decline is therefore important. READ MORE

2. Palaeogenomic reconstruction of woolly mammoth evolutionary history and extinction dynamics
Abstract : Biodiversity is declining globally. Yet, the biological and genetic processes associated with these declines on a longer timescale are still poorly understood. Ancient DNA is a powerful tool to study evolution in real-time. Despite advances in the field, there is further need for refinement of laboratory and computational techniques. READ MORE

3. Genomic analysis of the process leading up to the extinction of the woolly mammoth
Abstract : Species worldwide are subject to contractions in both abundance and geographical range, and their persistence in a changing environment may thus depend on the ability to survive in small and fragmented populations. Despite the urgent need to understand how extinction works, our knowledge of pre-extinction genetic processes is limited because techniques allowing population and conservation genomics to be studied in wild threatened populations have become available only recently.

4. Genetic structure, demographic change and extinction dynamics in the collared lemming and woolly mammoth
Abstract : In light of current climate change it is critical to understand how different species have been affected in the past by well-known climatic events. In this thesis, DNA was retrieved from ancient material to study the population dynamics of two cold-adapted taxa that capture the extremes of body size range in mammals: the collared lemming (Dicrostonyx sp.
