  1. 16. Effects of farmland heterogeneity at multiple spatial and temporal scales on house sparrow (Passer domesticus) population ecology

    Författare :Maria von Post; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Farmland heterogeneity; house sparrow; agricultural intensification; farm specialisation; landscape complementation; resource separation; population limitation;

    Sammanfattning : Strong declines of European farmland birds in recent decades are assumed to be caused by decreased food availability resulting from agricultural intensification and concomitant loss of farmland heterogeneity. One of the species suffering particularly strong declines in NW European countries is the house sparrow. LÄS MER

  3. 17. Disability in people with multiple sclerosis with focus on fatigue

    Författare :Sverker Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Disability; energy; fatigue; functioning; health services; multiple sclerosis; perceived impact on health;

    Sammanfattning : Background: Knowledge of the concurrent presence of disabilities and of their association with the perceived physical and psychological impact of MS on health in people with MS is sparse. Fatigue is commonly reported and may cause limitations in daily life. LÄS MER

  4. 18. Psychiatric comorbidity in multiple sclerosis : biological and epidemiological aspects

    Författare :Philip Brenner; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Multiple sclerosis (MS) is a chronic, neuroinflammatory disease and one of the leading reasons for neurological disability among young people in the Western World. MS patients commonly experience neuropsychiatric symptoms including depression and cognitive dysfunction. LÄS MER

  5. 19. Using multiple performance parameters in testing small graphical symbols

    Författare :Dominic Paul T. Piamonte; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk psykologi; Engineering Psychology;

    Sammanfattning : The main objective of the study was to analyse the understanding of small graphical symbols (pictograms and icons) among different potential user groups around the world using different test indices or parameters. Pilot studies using videophone symbols designed in Japan, USA and England were initially done. LÄS MER

  7. 20. Swedish seagrass ecosystems in a changing climate : Coastal connectivity and global change sensitivity

    Författare :Diana Perry; Martin Gullström; Jason Hall-Spencer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coastal seascape; shallow-water ecosystems; fish assemblages; connectivity; global change; climate change; multiple stressors; seagrass; Zostera marina; temperate region; Marine Ecology; marin ekologi;

    Sammanfattning : Coastal shallow-water ecosystems are essential for providing several goods and services globally, with seagrasses as an important contributor for maintaining high biodiversity and productivity within the nearshore seascape. The temperate species Zostera marina serves as a vital habitat for many species, including ecologically and economically important juvenile fish. LÄS MER
