  1. 1. Radar Measurements of Temporal Variation in a Boreal Forest

    Författare :Albert Monteith; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; remote sensing; temporal variation; tomography; antenna array; temporal coherence; Synthetic aperture radar SAR ;

    Sammanfattning : Synthetic aperture radar (SAR) on a satellite platform is a suitable technique for all-weather global monitoring of forest parameters such as biomass. This is important for increasing the accuracy of the global terrestrial carbon flux, the largest uncertainty in our current understanding of the Earth’s carbon cycle. LÄS MER

  4. 3. Seasonal variation and landscape regulation of dissolved organic carbon concentrations and character in Swedish boreal streams

    Författare :Anneli Ågren; Mats Jansson; Irena Creed; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DOC; temporal variation; spatial variation; seasonal variation; forested catchment; wetland catchment; catchment characteristics; DOC characteristics; absorbance-ratio; bioavailability.; Physical geography; Naturgeografi;

    Sammanfattning : The seasonal variation and landscape regulation of dissolved organic carbon (DOC) concentrations in streams have been studied in two watersheds in the boreal zone. The seasonal variation was found to be highly correlated to variations in runoff. An increase in runoff was always accompanied with an increase in DOC concentration. LÄS MER

  7. 5. MHC diversity and expression in a songbird : Temporal and transgenerational variation

    Författare :Samantha Mellinger; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MHC diversity; MHC-I gene expression; songbirds; genome assembly; amplicon HTS; temporal variation; family data; great reed warbler Acrocephalus arundinaceus ;

    Sammanfattning : The immune system is of central importance to clear-off pathogens in order to keep an organism healthy. In vertebrates, the Major Histocompatibility Complex (MHC) is a genomic region that holds key genes involved in adaptive immunity and in particular in the antigen presenting process. LÄS MER
