  1. 6. On the role of terrestrial ecosystems in a changing Arctic

    Författare :Adrian Gustafson; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Northern high latitudes; Arctic climate change; climate-vegetation feedbacks; shrubs; shrubification; treeline migration; LPJ-GUESS; RCA-GUESS; nitrogen; carbon; Northern high latitudes; Arctic climate change; climate-vegetation feedbacks; shrubs; shrubification; treeline migration; LPJ-GUESS; RCA-GUESS; Nitrogen; Carbon;

    Sammanfattning : The global temperature rise is proportional to the cumulative amount of CO2 emissions to the atmosphere. This observation is consistent between climate models and historical observations. LÄS MER

  3. 7. Aquatic vegetation in coastal ecosystems : The role of biotic interactions and environmental change for ecosystem functions and resilience in the Baltic Sea

    Författare :Åsa Austin; Johan S. Eklöf; Joakim P. Hansen; Serena Donadi; Matthew E. S. Bracken; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biodiversity; ecosystem functions; ecosystem multifunctionality; water clarity; fish recruitment; functional traits; feedbacks; biotic interactions; competition; facilitation; foundation species; seagrass; macrophytes; lagoons; brackish water; Baltic Sea; marin ekologi; Marine Ecology;

    Sammanfattning : Coastal ecosystems are among the most productive on Earth but subjected to many human pressures. In shallow coastal areas, aquatic vegetation constitutes foundation species that sustain secondary production and act as a nutrient filter, which may buffer human impacts. LÄS MER

  4. 8. Mitochondrial permeability transition following calcium overload. - Its role in neuronal cell death and potential as a pharmacological target

    Författare :Magnus Hansson; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; farmakognosi; farmaci; Bioenergetik; Bioenergetics; neuropsykologi; toxikologi; neurofysiologi; Neurologi; Neurology; neurophysiology; neuropsychology; Neurodegeneration; Mitochondria; Brain; Pharmacological sciences; pharmacognosy; pharmacy; Farmakologi; toxicology;

    Sammanfattning : There is currently no clinically available drug with neuroprotective properties to limit the evolving cell death following e.g. stroke or traumatic brain injury. The mitochondrial permeability transition (mPT) is a potential pathological mechanism causing cell death in the CNS. LÄS MER

  5. 9. Older and Feeling Unsafe? Unravelling the Role of Perceived Unsafety in the Well-being of Older Adults Residing in Senior Apartments

    Författare :Nadezhda Golovchanova; Katja Boersma; Henrik Andershed; Karin Hellfeldt; Liesbeth de Donder; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; perceived unsafety; fear of crime; well-being; life satisfaction; men-tal health; emotion regulation; vulnerability; older adults; advanced age; upplevd otrygghet; rädsla för brott; välmående; livstillfreds-ställelse; mental hälsa; känsloreglering; sårbarhet; äldre vuxna; åldrande;

    Sammanfattning : Feeling safe in one’s place of residence is important for the well-being of older adults when ageing in place; in contrast, feeling unsafe is likely to have negative consequences for well-being while ageing. Although substantial knowledge of perceived unsafety has been accumulated within various disciplines, there are certain knowledge gaps related to perceived unsafety in older age. LÄS MER

  7. 10. Forests, Functions, and Food Webs : Riparian processes through an ecological and molecular lens

    Författare :Jeffery Marker; Eva Bergman; Rolf Lutz Eckstein; Denis Lafage; Rachel E. Bowes; Ann Erlandsson; John S. Richardson; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Riparian systems; functional diversity; stable isotope analysis; metabarcoding; Tetragnathidae; Lycosidae; forestry management; prey subsidies; Biology; Biologi;

    Sammanfattning : Riparian systems are critical ecological interfaces that have a significant impact on the surrounding aquatic and terrestrial ecosystems. The riparian and surrounding systems have significant roles in regulating energy flow, providing essential nutrients, and supporting unique species, making them important for ecosystem function.
