1. 6. Population Dynamics and Conservation of the Sand Lizard (Lacerta agilis) on the Edge of its Range

   Författare :Sven-Åke Berglind; Pekka Pamilo; Per Sjögren-Gulve; Coulson Tim; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; demography; extinction; habitat; Lacerta agilis; management; metapopulation; peripheral populations; population dynamics; population viability analysis; reintroduction; reptiles; umbrella species; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

   Sammanfattning : The sand lizard (Lacerta agilis) reaches the northern periphery of its distribution in south-central Sweden, where small, isolated relict populations occur in pine heath forests on sandy sediments. Modern forestry and fire suppression have reduced the amount of suitable open habitat for the species in this area and seem to be important for its decline. LÄS MER

3. 7. From QTLs to Genes: Flowering Time Variation and CONSTANS-LIKE Genes in the Black Mustard (Brassica nigra)

   Författare :Marita Kruskopf Österberg; Martin Lascoux; Ulf Lagercrantz; Thomas Bataillon; Uppsala universitet; []
   Nyckelord :Molecular genetics; Flowering time; Brassica nigra; CONSTANS; CONSTANS-LIKE 1; Genetik;

   Sammanfattning : The transition to flowering is a major developmental switch in angiosperms, the timing of which is expected to be important for fitness. In this thesis the focus has been on identification of genes affecting natural variation in flowering time in Brassica nigra. The background for this thesis is an earlier QTL-mapping study in B. nigra. LÄS MER

4. 8. Adaptive Evolution and Demographic History of Norway Spruce (Picea Abies)

   Författare :Thomas Källman; Peter Tiffin; Uppsala universitet; []
   Nyckelord :;

   Sammanfattning : One of the major challenges in evolutionary biology is to determine the genetic basis of adaptive variation. In Norway spruce (Picea abies) the timing of bud set shows a very strong latitudinal cline despite a very low genetic differentiation between populations. LÄS MER

5. 9. Effects of Selection and Demography on DNA Polymorphism in Black Mustard (Brassica nigra)

   Författare :Per Sjödin; Martin Lascoux; Ulf Lagercrantz; Mikkel Schierup; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; population genetics; Genetik; Genetics; Genetik;

   Sammanfattning : The evolution of three genes from the CONSTANS-LIKE gene family is studied in Brassica nigra. We use a combination of population genetic and phylogenetic techniques in order to assess the relative importance of selection and demography on the pattern of DNA variation. LÄS MER

7. 10. Evolution of Flowering Time in the Tetraploid Capsella bursa-pastoris (Brassicaceae)

   Författare :Tanja Slotte; Martin Lascoux; Ulf Lagercrantz; Juliette de Meaux; Uppsala universitet; []
   Nyckelord :Biology; flowering time; homoeolog; hybridization; introgression; microarray; multiple origins; polyploid; QTL; Biologi;

   Sammanfattning : Although polyploidy is believed to be a major source of evolutionary novelty, few studies have examined the genetic basis of phenotypic variation in wild polyploids. In this thesis I have studied the genetic basis of flowering time variation in the wild tetraploid crucifer Capsella bursa-pastoris, as well as the evolutionary history of this species. LÄS MER
