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

    Author : Albert Monteith; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES; remote sensing; temporal variation; tomography; antenna array; temporal coherence; Synthetic aperture radar SAR ;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 5. Temporal variation and phytotoxicity of Batatasin-III produced by Empetrum hermaphroditum

    Author : Anna Wallstedt; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Palaeobotany; nitrogen uptake; photosynthesis; inhibition; temporal variation; chemical interference; boreal forest; Empetrum hermaphroditum; batatasin-III; phylogeny; palynology; Paleobotanik; fylogeni; palynologi; Biology; Biologi;

    Abstract : In northern Sweden, the clonal dwarf shrub Empetrum hermaphroditum Hagerup exerts strong inhibitory effects on other plant species. These inhibitory effects may, at least in part, be attributed to the high production of the secondary metabolite, batatasin-III, which is released from leaves and transported to the soil by rain (throughfall) and snowmelt.
