1. 1. 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

3. 2. Haga Företagscenter - historical and preliminary technical investigation of a contaminated site in Anderstorp, Småland, Sweden

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Max Boestam; [2022-12-21]
   Keywords : ;

   Abstract : The Haga Företagscenter site in Anderstorp, Sweden has a long industrial history, which include the extensive use of chlorinated solvents. Trichloroethene (TCE) was used in large quantities here but the release to the environment has not been previously investigated. READ MORE

4. 3. Aquaculture and its effect on the wild fish resource in a Swedish lake : An evaluation of changes in fat content, protein content and trophic niche

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

   Author : Emmy Nyberg; [2022]
   Keywords : Aquaculture; wild fish; fat content; protein content; stable isotopes;

   Abstract : Fish is nutritious and important as a food source for many people. It contains high levels of protein, important omega-3 fatty acids as well as micronutrients. For a sustainable fish consumption, aquaculture is needed but it can affect nearby ecosystems in many ways. READ MORE

5. 4. Arctica Islandica – Annually Banded Mollusc Offers High Temporal Resolution Record Into End Of North Sea Little Ice Age

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Eilidh Towers; [2022]
   Keywords : sclerochronology; Arctica islandica; palaeoenvironments; Little Ice Age; radiocarbon reservoir effect;

   Abstract : Sclerochronology affirms the well-established fact that banded growth increments in marine molluscs accurately record oscillations in climate and environment for the past millennia or more. This study considers how such records can enhance understanding of environmental shifts across the 18th to 20th centuries. READ MORE

6. 5. Traits of peat- and upland-derived stream dissolved organic carbon in the permafrost region around Abisko, northern Sweden

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Nora Kainz; [2021]
   Keywords : physical geography; ecosystem analysis; permafrost degradation; DOC; DOC concentration; stable isotope carbon signature; DOC quality; DOC degradation; Atmospheric Sciences and Biogeochemical Cycles; Earth and Environmental Sciences;

   Abstract : Climate change-induced thawing of permafrost mobilizes previously frozen carbon of high potential reactivity, thereby, fuelling microbiological production of greenhouse gases. For this work, an analysis of the quantity, quality, and bioreactivity of DOC in streams from the Stordalen discontinuous permafrost catchment was carried out with stream water samples during the relatively warm summer of 2018.
