  1. 1. Controls over stream temperature in a northern boreal landscape

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Oskar Damström; [2023]
    Keywords : Aquatic ecosystems; Climate change; Stream warming; Boreal streams;

    Abstract : With widespread increases in air temperature, it is expected that the temperature of aquatic ecosystems will also increase, especially at high latitudes. Warmer streams and rivers could have severe, direct impacts on cold-adapted aquatic fauna but may also indirectly influence species by reducing the amount of suitable habitat. READ MORE

  3. 2. Riparian vegetation ecology : an observational study into the effects of forest management on understory vegetation communities along boreal headwaters

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Ruben Jonathan Baan Hofman; [2023]
    Keywords : riparian forest; forest management; understory vegetation; headwater streams; community ecology;

    Abstract : Riparian forests along headwater streams have long been recognized for their role as an interface between the terrestrial and aquatic ecosystem. The over- and understory vegetation performs essential ecological and biochemical functions, which are important for stream functions. READ MORE

  4. 3. Sediment transport in small streams is related to riparian buffer width : a comparison between wide and narrow riparian buffers

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Rasmus Staaf; [2022]
    Keywords : Riparian Zone; Protective Zone; Headwater Stream; Forestry; Clear – cut Harvest; Organic Sediment; Inorganic Sediment; Near Stream Logging;

    Abstract : This study aims to provide information about how different widths of riparian buffers affect the quantity and quality of sediments transported in a small stream after a clear – cut harvest. Small streams have critical influences on downstream rivers and excessive transported sediments can have large negative effects on the aquatic system. READ MORE

  5. 4. Forest Ditches As Habitat For Aquatic Macroinvertebrate In Boreal Landscapes

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Lara Sánchez Calderón; [2022]
    Keywords : aquatic macroinvertebrates; drainage ditches; Sweden; mineral soil; peat soil; forestry;

    Abstract : Large areas of northern Sweden have been ditched to promote forest growth by draining wet soils and peatlands. These ditches have greatly added to length of Sweden’s stream and river network, but the ecological properties of these man-made aquatic environments is poorly understood. READ MORE

  6. 5. Dynamic streams in a pre-alpine catchment

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Andreas Sølberg; [2021-07-12]
    Keywords : Temporary streams; Streamflow; Stream mapping; Pre-Alpine catchment; Stream dynamics; Topographic wetness index; Upslope accumulated area;

    Abstract : This thesis aims to investigate the factors controlling the dynamics of temporary streams, i.e., streams that do not flow throughout the year. Temporary stream hydrology is a relative unexplored scientific field. READ MORE
