  3. 2. Diet of Arctic char and brown trout in Northern Sweden : potential effects of burbot and lake area

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Sebastian Dagman; [2023]
    Keywords : arctic char; brown trout; diet; stomach content; salmonids; burbot;

    Abstract : To manage and conserve different fish species, it is important to know what factors affect the presence and performance of the species. Relatively few studies have focused on burbot and how they interact with other species. READ MORE

  4. 3. 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

  5. 4. Legacy effects of temperature alterations on microbial resistance and resilience to drying and rewetting

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Franklin Lee Harris; [2023]
    Keywords : microbial ecology; soil; carbon dynamics; high latitudes; climate change; moisture stress; isotopes; respiration; trait based ecology; soil microbes; Environmental Changes in High Latitudes EnCHIL ; Earth and Environmental Sciences; Biology and Life Sciences;

    Abstract : With warming in soils due to climate change, a series of secondary factors arise, which have multifaceted effects on soil microbial communities. Of these, alterations to soil moisture are among the most crucial to understanding how microbial functions will change in the face of climate change. READ MORE

  6. 5. 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
