  1. 1. Biogeochemistry and Peat Properties of Restored Peatlands

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

    Author : Pelle Belaieff Kronborg; [2022]
    Keywords : Drainage; Bulk density; Nitrogen; Carbon; Stable isotopes;

    Abstract : Globally, peatlands comprise the most important soil organic carbon pool storing approximately one third of all terrestrial soil carbon. Drainage can turn peatlands to net sources of carbon dioxide. Peatlands have historically been drained to increase the productivity of agriculture and forestry. READ MORE

  3. 2. Beaver wetland and lake effects on Francisella tularensis in Swedish landscapes and hares

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

    Author : Lovisa Pihlgren Hökby; [2022]
    Keywords : tularemia; francisella tularensis hola; beavers; hares; wetland restauration; epizoology; vector borne diseases;

    Abstract : The zoonotic disease tularemia is caused by the bacterium Francisella tularensis that infects both humans and wildlife in Sweden. Associations between outbreaks of tularemia and lakes and rivers have earlier been observed, and semi-aquatic rodents and mosquitoes are believed to be key species groups in the epidemiological cycle of the disease.

  4. 3. Effects of drought on waterchemistry in a boreal streamnetwork

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

    Author : Enrique Gómez de Salazar Martínez; [2021]
    Keywords : : drought; boreal streams; Krycklan Catchment Study; land cover; biogeochemistry;

    Abstract : Hydrological drought at high latitudes represents a rising environmental hazard induced byglobal climate change. Yet, we still know little about how drought events influence thebiogeochemistry of boreal streams. READ MORE

  5. 4. When age makes all the difference : Methane production in sediment of contrasting Swedish lakes

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Ursula Ronja Zellmer; [2020]
    Keywords : sediment; methane; limnology; biogeochemistry;

    Abstract : Lakes are a significant source of the powerful greenhouse gas methane (CH4) globally. Methaneis produced through microbial processes in anoxic sediments. Methane emission from lakes ishighly variable in space and time. READ MORE

  6. 5. Beavers and environmental flow : the contribution of beaver dams to flood and drought prevention

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

    Author : Wali Uz Zaman; [2019]
    Keywords : beaver dam; beaver pond; environmental flow; flood; drought; GIS;

    Abstract : Before they were driven to near extinction, beavers populated the smaller rivers in Europe, Asia and North America. They are ecosystem engineers, since their dam building activities have a cascading effect on biogeochemistry, hydrology, ecosystem structure as well as biodiversity of the affected and surrounding area.
