  1. 1. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

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

    Author : Rasmus Staaf; [2024]
    Keywords : artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

    Abstract : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

  3. 2. Dynamic minimum flows in the bypass reach of Juktån : A post-implementation evaluation of the effects on riparian vegetation

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

    Author : Walter Gezelius Gezelius; [2024]
    Keywords : Restoration; Environmental flows; riparian vegetation;

    Abstract : The purpose of the paper was to evaluate the effects of the restoration efforts in Juktån on the plant species richness and composition, vegetation zonation and soil composition. The restoration involved implementation of a dynamic flow, in addition to hydro-geomorphological alterations. READ MORE

  4. 3. Non-native plants in mountain ecosystems. An exploration of plant diversity and its response to road disturbance and alien invasion.

    University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Author : Anderberg Lina; [2023-10-19]
    Keywords : ;

    Abstract : Understanding patterns of invasive plants becomes ever more important as anthropogenic presence continues to facilitate their spread. In mountainous landscapes, cases of establishment by nonnative species have become frequent, despite the environmentally unfavorable conditions for plants less adapted to the harsh climate.

  5. 4. The bzzzt of frirends. Interspecific competition in Arctic plants for pollination services.

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Malin Olsson; [2023-06-27]
    Keywords : the Arctic; pollinator networks; competition; autonomous selfing; Arktis; pollinationsnätverk; konkurrens; autonom självpollinering;

    Abstract : The Arctic has a harsh environment that is challenging for the flora and fauna that inhabits the region. The ruling abiotic factors of the region results is a low species richness that creates a potential challenge for the region’s plant species. READ MORE

  6. 5. Pollinator communities on a landscape complexity gradient in southern Sweden

    University essay from SLU/Dept. of Ecology

    Author : Hanna Olsson; [2023]
    Keywords : pollinator; bumblebee; rough pasture; semi-natural pasture; unimproved grazing; landscape complexity;

    Abstract : Investigating how pollinator populations are affected by land use changes is crucial for predicting their persistence in the landscape and thereby the persistence of the significant service they provide to crop production. Pollinator populations are subjected to multiple threats, particularly overall intensification of cropping systems and landscape simplification. READ MORE
