1. 1. Systematics of polyploid Dactylorhiza (Orchidaceae) - genetic diversity, phylogeography and evolution

   Författare :Sofie Olofsson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microsatellites; allozymes; ITS; plastid DNA; Dactylorhiza majalis ssp. traunsteineri; allopolyploidy; AFLPs; immigration history; diploidization; hybridization;

   Sammanfattning : This thesis examines genetic variation in allotetraploids of the Dactylorhiza incarnata/maculata polyploid complex in different parts of Europe. The molecular markers used were AFLPs, allozymes, ITS, nuclear microsatellites and plastid DNA markers. LÄS MER

3. 2. Stellar Winds of Cool Giants : Investigating the Mass-Loss Mechanism of AGB Stars

   Författare :Sofie Liljegren; Susanne Höfner; Kjell Eriksson; Bernd Freytag; Hans Olofsson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; late-type stars; AGB stars; stellar winds; stellar atmospheres; dust; stellar pulsation; hydrodynamics; radiative transfer;

   Sammanfattning : Asymptotic giant branch (AGB) stars are luminous cool giants of low to intermediate mass that are strongly pulsating and non-spherical, with heavy mass loss through a stellar wind. The mass loss makes these stars important for galactic chemistry, as the wind enriches the interstellar medium with new elements and dust, and it determines the final fate of these stars. LÄS MER
