Tracing silicon cycling in the Okavango Delta, a sub-tropical flood-pulse wetland using silicon isotopes
(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 ...
Assessment of benefits and risks of growing Jatropha (Jatropha curcas) as a biofuel crop in sub-Saharan Africa: a contribution to agronomic and socio-economic policies
(Springer Link, https://link.springer.com, 2017-07-17)
In sub-Saharan Africa (SSA), the main goals behind the development of a biofuel industry are employment creation and income generation. Jatropha (Jatropha curcas L.) has emerged as a candidate for biodiesel production. It ...
Rival group scent induces changes in dwarf mongoose immediate behavior and subsequent movement
(Behavioral Ecology, https://academic.oup.com/beheco, 2016-05-15)
In many social species, groups of animals defend a shared territory against rival conspecifics. Intruders can be detected from a variety of cues, including fecal deposits, and the strength of response is expected to vary ...
The effects of extended water supply disruptions on the operations of SMEs
(African Journal Online, https://www.ajol.info, 2017)
The objective of this study was to analyse the effects of extended water supply disruptions on SMEs, in relation to returns, profitability and expenditure patterns. It investigated the impact of regular and/ or extended ...
Abiotic and biotic factors influencing the mobility of arsenic in groundwater of a through-flow island in the Okavango Delta, Botswana
(Elsevier, https://www.elsevier.com, 2014-10-10)
The Okavango Delta of Botswana is a large arid-zone wetland comprising 20,000 km2 of permanent and seasonal floodplains and over 100,000 islands. It has been shown that island groundwater can have very high dissolved arsenic ...
Physicochemical controls of diffusive methane fluxes in the Okavango Delta, Botswana.
(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 ...
A vegetation-based hierarchical classification for seasonally pulsed floodplains in the Okavango Delta, Botswana
(Taylor & Francis, http://taylorandfrancis.com, 2011-12-11)
A classification scheme is presented for seasonal floodplains of the Boro-Xudum distributary of the Okavango Delta, Botswana. This distributary is subject to an annual flood-pulse, the inundated area varying from a mean ...
Sap flow variation in selected riparian woodland species in the Okavango Delta, Botswana
(Wiley, https://onlinelibrary.wiley.com, 2017-04-28)
In the tropical Okavango Delta, transpiration by trees is an important process partly responsible for maintaining the basin as a freshwater environment. Quantification of evapotranspiration from terrestrial landforms of ...
Macrophyte species distribution, indices of biotic integrity, and sampling intensity in isolated Florida marshes
(Springer Link, https://link.springer.com, 2012)
This study examined the distribution of wetland plants used in macrophyte-based index of biotic integrity (IBI) metrics to determine the effectiveness of zone sampling in assessing wetland condition. Using sampling data ...
Dynamics of the feeding ecology of selected fish species from the Okavango River delta, Botswana
(Acta Ichthyologica et Piscatoria, https://www.aiep.pl, 2012)
Background. This study contributes to the understanding of the potential impact of changes in flooding patterns and (potential) fish production as a consequence of upstream developments in floodplain systems. Therefore, ...
