  2. 11. Familial thoracic aortic aneurysms and dissections : studies on genotype and phenotype

    Author : Matias Hannuksela; Bo Carlberg; Bengt Johansson; Eva-Lena Stattin; Anders Gottsäter; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Thoracic aorta; familial aortic aneurysm; familial aortic dissection; genetics; aortic stiffness;

    Abstract : Background: Thoracic aortic aneurysms and dissections (TAAD) have a genetic component with an estimated 20-25% of the patients having a positive family history. An aneurysm often precedes a dissection. Acute aortic dissections are associated with high mortality and morbidity, even when operated on. READ MORE

  4. 12. Stress Coping Strategies in Brown Trout (Salmo Trutta): Ecological Significance and Effects of Sea-Ranching

    Author : Daniel Brelin; Svante Winberg; Erik Petersson; Jörgen Johnsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zoophysiology; Stress-coping-strategies; Animal-personalities; Behavioral-syndromes; Brown trout; Salmo trutta; Catecholamines; Sexual maturation; Hatchery; Phenotype; Learning; Zoofysiologi; Biology; Biologi;

    Abstract : Two distinct stress coping strategies, proactive and reactive, have been stated in various animal studies, each associated with a set of behavioural and physiological characteristics. In a given challenging situation, proactive animals show more aggression, a higher general activity and a predominant sympathetic reaction. READ MORE

  5. 13. Phenotypic and Genotypic responses in the planktonic diatom Skeletonema marinoi - Effects of Natural Processes and Anthropogenic Stressors

    Author : Susanna Gross; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diatoms; genotype; phenotype; resting cell; eutrophication; spring bloom; diversity; grazing; adaptation; phytoplankton; microalgae; Skeletonema;

    Abstract : Diatoms are one of the most diverse and abundant phytoplankton taxa and are highly important as primary producers, accounting for nearly half of the marine primary production and constituting the base in the marine food web. Despite their high dispersal potential they are genetically diverse and display genetically structured populations. READ MORE

  6. 14. Hybrid zone dynamics, assortative mating, and migratory programmes in a willow warbler migratory divide

    Author : Keith W. Larson; Susanne Åkesson; Staffan Bensch; Martin Schaefer; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; migratory divide; phenotype; willow warbler; hybrid zone; tension zone; Phylloscopus trochilus; migratype; assortative mating; migration; biology; biologi; evolutionär genetik; evolutionary genetics; migratory divide; phenotype; willow warbler; hybrid zone; tension zone; Phylloscopus trochilus; migratype; assortative mating; migration;

    Abstract : In this thesis I will compare and contrast the two willow warbler subspecies (Phylloscopus trochilus trochilus and P. t. acredula) with differing migratory phenotypes (or "migratype") in the context of their migratory divide and hybrid zone in central Sweden. Their migratory programs differ in the direction and distance traveled during migration. READ MORE
