  1. 1. 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

  3. 2. Plant community responses to 15 years of nitrogen and phosphorus fertilization along an elevational gradient in the subarctic tundra

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

    Author : Gaya Ten Kate; [2023]
    Keywords : arctic tundra; climate change; fertilization; nitrogen; phosphorus; plant community composition; species richness; Simpson’s diversity; Shannon-Wiener diversity; elevational gradient;

    Abstract : Climate change in the Arctic has profound effects on tundra vegetation, directly through increasing temperatures and indirectly through changes in plant community composition and nutrient cycling. Fertilization experiments are widely used to study the effects of increased nutrient availability on arctic tundra vegetation. READ MORE

  4. 3. MOUNTAIN ROADS AND THE HOMOGENIZATION OF PLANTS. A study on plant communities and their traits along the elevational gradient.

    University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Author : Violetta Chernoray; [2022-09-28]
    Keywords : anthropogenic disturbance; spatial ecology; Northern Scandes; functional traits; roadsides; beta-diversity.;

    Abstract : Overexploitation, land use, and other anthropogenic disturbances have increased in recent years, and are expected to increase even further. A very common anthropogenic disturbance, that can be seen even as far as in mountain regions, is roads. READ MORE

  5. 4. FLOWERING TIME DEPENDENCE ON MICROCLIMATE ACROSS AN ELEVATIONAL GRADIENT IN ARCTIC PLANT COMMUNITIES

    University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Author : Maria Pavolotskaia; [2022-07-06]
    Keywords : The Arctic; flowering time; flowering phenology; elevation; elevational gradient; temperature; snowmelt; snow cover; microclimate.;

    Abstract : The Arctic is the fastest-warming region on Earth. Arctic plant communities are highly sensitive to temperature change; temperature-dependent advancement of flowering dates has already been observed in the Arctic. Flowering time is critical for reproductive success. READ MORE

  6. 5. INDIVIDUAL TRAIT MATCHING OF BUMBLEBEES (BOMBUS) AND FLOWERS ALONG AN ENVIRONMENTAL GRADIENT

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

    Author : Johan Per Michael Svedin; [2022]
    Keywords : Arctic climate change; Bombus; Flower morphology; Plant-pollinator trait-matching;

    Abstract : Insect pollinators serve a critical role in maintaining plant biodiversity and are especially susceptible to changes within their environment. To study the possible effects of seasonal variation in temperature, as well as climatic temperature increase on the plant-pollinator community, the relationship between bumblebee and flowering plant traits along an elevational gradient, representing warming-induced changes in plant community, were examined.
