  • Physicochemical controls of diffusive methane fluxes in the Okavango Delta, Botswana. 

    Masamba, Wellington R.L.; Gondwe, Mangaliso J.; Murray-Hudson, Mike (Springer Science, https://link.springer.com, 2015)
    Atmospheric methane (CH4) is one of the three key greenhouse gases (GHGs) driving global climate change. The atmospheric concentration of CH4 has increased by about 150 % above pre-industrial levels of 400–700 ppb due to ...
  • The role of vegetation in the Okavango Delta silica sink 

    Struy, Eric; Mosimane, Keotshephile; Van Pelt, Dimitri; Hudson, Mike Murray; Meire, Patrick; Frings, Patrick; Wolski, Piotr; Schaller, Jörg; Schoelynck, Jonas; Conley, Daniel J.; Gondwe, Mangaliso J. (Springer Link; https://link.springer.com, 2014-12-16)
    We assessed the role of vegetation and hydrology in the Si cycle in the Okavango Delta. Our results show a large storage of biogenic Si (BSi) in vegetation and the sediments. The biological storage is among the highest ...
  • Tracing silicon cycling in the Okavango Delta, a sub-tropical flood-pulse wetland using silicon isotopes 

    Frings, Patrick J.; De La Rocha, Christina; Struyf, Eric; van Pelt, Dimitri; Schoelynck, Jonas; Murray-Hudson, Mike; Gondwe, Mangaliso J.; Wolsk, Piotr; Mosimane, Keotsheple; Gray, William; Schallerf, Jorg; Conley, Daniel J. (Elservier, https://www.elsevier.com, 2014-07-22)
    Chemical weathering of silicate minerals releases elements into solution whereas the neoformation of secondary minerals works in the opposite direction, potentially confounding estimates of silicate weathering rates. Silicon ...
  • Water balance and variations of nutrients and major solutes along a river transect through the Okavango Delta, Botswana 

    Gondwe, Mangaliso J.; Masamba, Wellington R.L.; Murray-Hudson, Michael (Botswana Notes and Records; http://journals.ub.bw/index.php/bnr/, 2017-07-05)
    Wetland goods and services provide a means of survival for many riparian rural communities in developing countries, particularly in the Sub-Saharan Africa. To sustain the provision of goods and services for human use, ...
