  1. 1. Växt-växtbaserad kommunikation : hur sortblandningar påverkade tillväxten hos vårkorn

    University essay from SLU/Dept. of Ecology

    Author : Alexander Pettersson; [2021]
    Keywords : allelobios; allelopati; flyktiga organiska substanser; vårkorn;

    Abstract : Växter utgör grunden för många ekosystem och näringskedjor. Som platsbundna organismer behöver växter kunna anpassa sig efter de rådande förutsättningarna kring växtplatsen. Växter anpassar sig inte bara efter abiotiska faktorer, utan även stress från skadegörare och andra växter spelar en stor roll för en växtens överlevnad. READ MORE

  3. 2. Methane flux from Carex ramenskii on coastal meadows and grazing lawns in western Alaska

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

    Author : Kaj Lynöe; [2017]
    Keywords : Arctic wetlands; Greenhouse gases; CH4 emission; Plant mediated gas release; Geese grazing;

    Abstract : In this study we determined the magnitude of plant mediated CH4 emission (flux) in two vegetation types of Carex ramenskii. The objectives of this paper were to quantify the proportion of CH4 emissions from plant mediated flux and the total flux (plant and soil). READ MORE

  4. 3. Analys av metanflöden från sjön Erken

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Ryan Mintz; [2016]
    Keywords : methane; transfer velocity; flux; waterside concentration; eddy covariance; Nyckelord: metan; utbyteskoefficient; flux; metankoncentration; eddy kovarians;

    Abstract : While it is not the most abundant greenhouse gas, a significant portion of the greenhouse effect is caused by methane. The amount of methane in the atmosphere is increasing, indicating that there is a continuous source of methane to the atmosphere. READ MORE

  5. 4. Variability of GHG emissions from emergent aquatic macrophytes in mixed boreal and Equisetum dominated communities

    University essay from Linköpings universitet/Tema Miljöförändring; Linköpings universitet/Filosofiska fakulteten

    Author : Nina Marliden; [2015]
    Keywords : plant-mediated; GHG flux; methane; carbon dioxide; nitrous oxide; Equisetum fluviatile; wetland; lake;

    Abstract : Plants (macrophytes) growing in lake and wetland sediments are known mediators of greenhouse gases (GHG), specifically methane (CH4), carbon dioxide (CO2) and nitrous oxide (N2O). Current studies have emphasized the potential risk of underestimation regarding emissions of plant-mediated GHGs from terrestrial systems including lakes, streams and other freshwater bodies.

  6. 5. Diurnal variation in methane flux in a low-arctic fen in Southwest Greenland

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Bjarne Munk Lyshede; [2012]
    Keywords : geography; physical geography and ecosystem analysis; diurnal; methane; wetland; Arctic; Greenland; Earth and Environmental Sciences;

    Abstract : Popular science: A Day in the Life of a Methane Bog Methane gas is continuously released from wetlands around the world. In Kobbefjord, Greenland the release of methane is low during the cold of winter and higher in warm summer months. But the amount released also varies from day to night; a pattern that has to do with both temperature and light. READ MORE
