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

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

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

    Sammanfattning : 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. LÄS MER

  3. 7. Hydrological control of plant species composition and distribution in Dal River alluvial meadows

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Matouš Jimel; [2023]
    Nyckelord :Riparian zone; Alluvial meadows; Riparian vegetation; Regulated river; Flooding;

    Sammanfattning : Northern boreal alluvial meadows are ecologically significant semi-natural ecosystems within the riparian zone. The effects of disturbance like flooding, grazing, and mowing have historically maintained high nutrient turnover and succession disruption that led to high biodiversity, leading to their inclusion in the Natura 2000 network.

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

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

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

    Sammanfattning : 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. LÄS MER

  5. 9. Go with the flow - can environmental flows save us? : A study of the flow patterns in Bredforsen and possibilities for the future

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Hilda Brynjarsdotter; [2022]
    Nyckelord :Riparian zone; Riparian vegetation; Riparian vegetation zones; Regulated rivers; Floodings; hydropower;

    Sammanfattning : Freshwater systems have, during human history, endured large-scale impacts. According to the water framework directive, measures must be developed to create a better environment for species in, and connected to, freshwater systems. Hydropower plants has caused loss of natural disturbance (e.g. LÄS MER

  7. 10. En inventering av bottenfauna i Trönningeån med två biflöden

    Kandidat-uppsats, Högskolan i Halmstad

    Författare :Johannes Glännman; Kalle Ström Töttrup; [2022]
    Nyckelord :Bottenfauna; Trönningeån; ekologi;

    Sammanfattning : Benthic macroinvertebrates are usually small animals living in our lentic and lotic ecosystems, they have been used as indicators of water quality and biodiversity for a long time. Dam removals have become one of the “go-to” conservation methods for restoring connectivity in lotic ecosystems and thereby enabling passage upstream for migrating species. LÄS MER
