  1. 1. The role of HMG-coenzyme A reductase (HMGCR) and statin medication in the Central Nervous System : Cognitive Functions, Metabolism, Feeding and Sleep Behaviour

    Författare :Ahmed Alsehli; Helgi B. Schiöth; Michael J. Williams; Heinrich Dircksen; Uppsala universitet; []
    Nyckelord :Statin; cardiovascular disease; HMGCR; PCSK9; sleep; insomnia; circadian; Chronotype; feeding;

    Sammanfattning : Millions of people are currently on statin medications (HMGCR inhibitors) to prevent cardiovascular diseases. Despite considerable central nervous system expression, little is known about HMGCR function in the brain. LÄS MER

  3. 2. Transport by Benthic Macrofauna: Functional Classification and Biogeochemical Response

    Författare :Stina Lindqvist; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Marine sediments; Early diagenesis; Bioturbation; Functional groups; Benthic fluxes; Imaging; Ecosystem function; Sediment reworking; Transport proxies; Fluorescent particles;

    Sammanfattning : Burrowing and reworking activities by benthic macrofauna regulate rates and pathways during organic matter mineralisation in bioturbated sediments. In so doing, they also affect the overall cycling of elements crucial in the biosphere (e.g. C, N, P, Fe, Mn and S). LÄS MER

  4. 3. The Macroinvertebrate Community in a Nature-like Fishway with Habitat Compensation Properties

    Författare :Stina Gustafsson; Olle Calles; Martin Österling; Jostein Skurdal; John Brittain; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nature-like fishway; biodiversity; macroinvertebrates; functional feeding groups; Biology; Biologi;

    Sammanfattning : Nature-like fishways are often constructed to restore connectivity in streams exploited for hydropower. They also have the potential to compensate for important habitats that have been degraded or lost. LÄS MER

  5. 4. Habitat compensation in nature-like fishways : Effects on benthos and fish

    Författare :Stina Gustafsson; Olle Calles; Martin Österling; Jostein Skurdal; Paul Giller; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biocanal; biodiversity; brown trout; freshwater pearl mussel; functional feeding groups; habitat heterogeneity; large woody debris; macroinvertebrates; PIT-tag; salmonids; Biology; Biologi;

    Sammanfattning : The construction of nature-like fishways has become an increasingly common measure to restore longitudinal connectivity in streams and rivers affected by hydroelectric development. These fishways also have the potential to function as habitat compensation measures when running waters have been degraded or lost. LÄS MER

  7. 5. Species community structure and functional redundancy in Swedish headwater streams : local versus regional control

    Författare :Emma Göthe; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Streams and rivers only contain a small proportion of the Earth's freshwater, but nevertheless harbour much biodiversity. Headwater streams are the most prevalent running water environments, but despite their wide distribution, they are often excluded from important freshwater legislation and national monitoring programmes.
