  1. 1. Carbon sequestration processes in tropical seagrass beds

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Liberatus Dominick Lyimo; Mats Björk; Martin Gullström; Mariam Hamis; Teresa Alcoverro; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Seagrass; Carbon sequestration; Carbon sink; Eutrophication; Productivity; Nitrous oxide; Methane; Greenhouse gases; Tropical; Eastern Africa; växtfysiologi; Plant Physiology;

    Abstract : Seagrass meadows may play a substantial role in climate change mitigation as they are capable to sequester and store substantial amounts of anthropogenic carbon in plant biomass and, more importantly, in their underlying sediments. In this PhD thesis, the carbon-burial potential was assessed by quantifying the amount of organic carbon stored in different seagrass meadows, each dominated by one of the four major seagrass species in the Western Indian Ocean region.

  2. 2. Flocculation of Allochthonous Dissolved Organic Matter – a Significant Pathway of Sedimentation and Carbon Burial in Lakes

    University dissertation from Uppsala : Universitetsbiblioteket

    Author : Eddie von Wachenfeldt; Lars Tranvik; David Bastviken; John Downing; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; flocculation; dissolved organic carbon; allochthonous; carbon sequestration; carbon cycle; boreal lakes; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Freshwater ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi Limnisk ekologi;

    Abstract : Inland waters receive substantial amounts of organic carbon from adjacent watersheds. Only about half of the carbon exported from inland waters reaches the oceans, while the remainder is lost en route. This thesis identifies flocculation as an important and significant fate of carbon in the boreal landscape. READ MORE

  3. 3. Permafrost carbon in a changing Arctic On periglacial landscape dynamics, organic matter characteristics, and the stability of a globally significant carbon pool

    University dissertation from Stockholm : Department of Physical Geography, Stockholm University

    Author : Niels Weiss; Peter Kuhry; Duane Froese; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Permafrost; Carbon; Climate; Arctic; Soil; Organic Matter; Cryosphere; Geomorphology; naturgeografi; Physical Geography;

    Abstract : Organic matter (OM) in arctic permafrost ground contains about twice as much carbon (C) as is currently present in the atmosphere. Climate change is particularly strong in the Arctic, and could cause a considerable part of the OM in permafrost to thaw out, decompose, and be released as greenhouse gases; further enhancing global warming.

  4. 4. Carbon stocks and fluxes in a young Siberian larch (Larix sibirica) plantation in Iceland

    University dissertation from Stockholm : Department of Physical Geography, Stockholm University

    Author : Brynhildur Bjarnadottir; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; interannual variability; carbon balance; Larix sibirica; afforestation; stock-change method; carbon sequestration; eddy covariance; biomass functions;

    Abstract : The understanding of how forests function with respect to carbon (C) balance and its interaction with the climate system is a fundamental question in climate change research. Another important question is how large the sink for CO2 is in northern forests and how it varies with forest type, management, stand age and with external factors, such as climate variability.

  5. 5. Ectomycorrhizal fungi: Their role in nitrogen retention and carbon sequestration in northern coniferous forests

    University dissertation from Department of Biology, Lund University

    Author : Adam Bahr; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ectomycorrhizal fungi; Carbon sequestration; Nitrogen deposition; Nitrogen leakage; Field survey; Boreo-nemoral forest; Boreal Forest; Ergosterol; Free ergosterol; Mesh-bags; Multivariate analysis;

    Abstract : Almost all northern forest tree species live in symbioses with ectomycorrhizal fungi (EMF). The trees allocate up to half of the photoassimilated carbon (C) through the roots to EMF. In return EMF deliver nutrients from both inorganic and organic sources in the soil, as well as water. READ MORE
