  2. 16. Mosses as mediators of climate change : implications for tree seedling establishment in the tundra

    Author : Signe Lett; Ellen Dorrepaal; David Wardle; Marie-Charlotte Nilsson; Vigdis Vandvik; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; arctic; alpine; B. pubescens; bryophytes; competition; facilitation; mosses; P. sylvestris; precipitation changes; seedlings; traits; tree line; warming;

    Abstract : Alpine and arctic tree line expansion depends on the establishment of tree seedlings above the current tree line, which is expected to occur with climate warming. However, tree lines often fail to respond to higher temperatures. Other environmental factors are therefore likely important for tree seedling establishment. READ MORE

  4. 17. Preferential Processing: a factor with implications : Personality traits as explanatory factors

    Author : Mats Najström; Lennart Högman; Anders Flykt; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Preferential preattentive processing; trait anxiety; emotional vulnerability; SCR; Psychology; Psykologi; psykologi; Psychology;

    Abstract : Preferential processing favouring threatening information has received increased attention because cognitive formulations have placed increased emphasis on its role as a key cognitive factor underlying vulnerability to and maintenance of anxiety disorders. The present dissertation comprises four empirical studies within the area of preferential processing. READ MORE

  5. 18. On the importance of inflammation for personality traits and psychiatric morbidity

    Author : Petra Suchankova; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; inflammation; C-reactive protein; complement factor H; S100B; receptor for advanced glycation end products; polymorphism; gene expression; personality traits; suicidal behaviour; schizophrenia; depression; Flinders sensitive line;

    Abstract : Background: Pro-inflammatory mediators have been implicated in processes that could be both beneficial and toxic to cells in the brain. On the one hand balanced levels of these mediators favour e.g. READ MORE

  6. 19. Linking functional traits and cultural ecosystem services in urban areas through human preferences

    Author : Julie Goodness; Erik Andersson; Thomas Elmqvist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Functional traits; ecosystem services; cultural ecosystem services; urban; cities; human perception; preferences; ecosystem management; vetenskap om hållbar utveckling; Sustainability Science;

    Abstract : Urban areas are now the daily lived experience for the majority of the world’s people, and it is therefore important to explore what kind of ecological communities and corresponding ecosystem functions and services are being generated in these environments. Urban areas are shaped by a variety of factors, but arguably one of the most influential is that of people, in terms of how their preferences and active selective choices for biota play out in the landscape.

  7. 20. Genetic Heteroscedasticity for Domestic Animal Traits

    Author : Majbritt Felleki; Erling Strandberg; Lars Rönnegård; Ole Fredslund Christensen; Högskolan Dalarna; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Quantitative genetics; genetic heteroscedasticity of residuals; genetic heterogeneity of environmental variation; genetic heterogeneity of residual variance; double hierarchical generalized linear models; teat count in pigs; litter size in pigs; milk yield in cows; somatic cell count in cows; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Abstract : Animal traits differ not only in mean, but also in variation around the mean. For instance, one sire’s daughter group may be very homogeneous, while another sire’s daughters are much more heterogeneous in performance. The difference in residual variance can partially be explained by genetic differences. READ MORE
