1. 21. Genetic diversity and hardiness in Scots pine from Scandinavia to Russia

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Jenny Olsson; [2019]
   Keywords : Pinus sylvestris; recolonization history; genetic diversity; cold hardiness; clinal variation;

   Abstract : The postglacial recolonization of northern Europe supposedly originated from Western Europe and the Russian Plain, however, recent molecular and macrofossil-based investigations suggest that the history may be more complex than previously thought. This study aims to investigate the genetic diversity and population structure of Scots pine from Scandinavia to Russia to re-evaluate its recolonization history, and to examine whether the pattern of spatial genetic diversity has any adaptive significance.

3. 22. Estimating the Early Evolution of Brachiopods Using an Integrated Approach Combining Genomics and Fossils

   University essay from Uppsala universitet/Paleobiologi

   Author : Chloé Robert; [2019]
   Keywords : Brachiopoda; evolutionary history; phylogeny; Maximum likelihood; Bayesian inference; fossil calibrations; Brachiopoda; evolutionhistoria; fylogeni; Maximum likelihood-metoden; Bayesiansk statistik; fossilkalibering;

   Abstract : The Brachiopoda, a major group of the Lophotrochozoa, experienced a rapid early evolutionary diversification during the well-known Cambrian explosion and subsequently dominated the Palaeozoic benthos with its diversity and abundance. Even though the phylogeny of the Lophotrochozoa is still hotly debated, it is now known that the Brachiopoda are a monophyletic grouping. READ MORE

4. 23. Formation and Evolution of Protoplanetary Disks

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Johan Appelgren; [2019]
   Keywords : protoplanetary disk; protoplanetary disk formation; protoplanetary disk evolution; planet formation; Physics and Astronomy;

   Abstract : A star forms with a surrounding protoplanetary disk after the collapse of a molecular cloud core. Subsequently, over a period of several Myr this protoplanetary disk of dust and gas is accreted onto the host star. We model the formation and evolution of such a protoplanetary disk using a one-dimensional numerical model. READ MORE

5. 24. Genomic analyses of Scandinavian TRB farmers and their relation to other Neolithic populations

   University essay from Uppsala universitet/Människans evolution; Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Tatiana Ruiz-Bedoya; [2018]
   Keywords : ;

   Abstract : Human population history and the social composition of human groups during the Middle Neolithic (MN) in Scandinavia is still to be fully understood. The possibility of obtaining genomic data from ancient tissues has opened a new horizon for understanding ancient human populations. READ MORE

6. 25. SVenX: A highly parallelized pipeline for structural variation detection using linked read whole genome sequencing data

   University essay from Lunds universitet/Examensarbeten i bioinformatik

   Author : Vanja Börjesson; [2018]
   Keywords : Biology and Life Sciences;

   Abstract : Genomic rearrangements larger than 50 bp are called structural variants. As a group, they affect the phenotypic diversity among humans and have been associated with many human disorders including neurodevelopmental disorder and cancer. READ MORE
