  2. 11. Spatial heterogeneity and biotic interactions : scaling from experiments to natural systems

    Author : Ulf Bergström; Göran Englund; Erik Bonsdorff; Sebastian Diehl; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; zooekologi; Animal Ecology;

    Abstract : Much of current ecological theory stems from experimental studies. These studies have often been conducted in closed systems, at spatial scales that are much smaller than the systems of interest. READ MORE

  4. 12. Negative experiences of encounters in healthcare

    Author : Maja Wessel; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : A positive encounter is essential to the provision of qualitative healthcare. Experiences of negative encounters in healthcare may affect the patient’s wellbeing and health, and have a negative effect on the patient’s trust in the healthcare system. READ MORE

  5. 13. Deformation zones in models and nature

    Author : Katarina Sofia Persson; Carl Ehlers; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; mineralogi; petrologi och tektonik; Mineral Chemistry; Petrology and Tectonics;

    Abstract : Field studies encounter several complicating factors not studied in the models. Examples are oblique convergence, heterogeneous materials and thermal softening by intruding magmas. READ MORE

  6. 14. Near-ambient pressure velocity map imaging

    Abstract : Catalytic reactions on solid surfaces have been studied under Ultra-high vacuum (UHV) conditions for decades. These studies provide crucial information for catalytic reactions, such as surface structures, adsorption sites, and reaction mechanisms. READ MORE

  7. 15. Interactions between natural enemies and the dioecious herb Silene dioica

    Author : Viktoria Pettersson; Barbara E. Giles; Lars Ericson; Pia Mutikainen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silene dioica; Delia criniventris; Caryocolum viscariella; Microbotryum violaceum; plant-herbivore interactions; plant -pathogen interactions; sex bias; sex rato; successional gradients; fitness effects; Skeppsvik Archipelago; Terrestrial ecology; Terrestisk ekologi; ekologisk botanik; Ecological Botany;

    Abstract : About 6% of all angiosperms are dioecious. This separation of sexual function to male and female individuals, and the fundamentally different patterns of reproductive resource allocation that follows that separation, are thought to have important ecological and evolutionary consequences for plant enemy interactions.
