  • 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 ...
